4 1 The multiplexer / de-multiplexer pair at a glance The SDI-TD-3GMX-5 is a Flashlink time-division multiplexer (TDM) that either allows any pair of supported HD-SDI or SD-SDI inputs or a single HD-SDI or SD-SDI input, plus up to 4 SD-SDI inputs to be transported over a single 3GHD-SDI link. The SDI-TD-3GDX-5 is a Flashlink time division de-multiplexer that either recovers the 2 HD-SDI/SD-SDI streams or the single HD-SDI/SD-SDI stream plus 4xSD-SDI streams from the 3GHD transport signal. The selection is automatic, based on what is detected in the stream. The HD-TD-3GMX-2 is a Flashlink time-division multiplexer (TDM) that allows any pair of supported HD-SDI or SD-SDI inputs to be transported over a single 3GHD-SDI link. The HD-TD-3GDX-2 is a Flashlink time division de-multiplexer that recovers the 2 HD- SDI/SD-SDI streams from the 3GHD transport signal. Other key features of the multiplexer / de-multiplexer pair include: Supports all the most common video standards including SDTI. Accepts any combination of synchronous or asynchronous HD-SDI 1485 Mbps or SD-SDI 270 Mbps input formats, as long as the video standard is supported. Correct video formats will be recovered at the de-multiplexer end. Separate stream clock reference data for each channel is transferred for remote clock regeneration. Correct clocks will be recovered at the de-multiplexer end. Automatic input format detection for each channel. All streams embedded in the 3GHD transport signal are completely independent. No cross-contamination of the other stream when one input is lost. Low latency. Can be combined with SDI-TD-MUX-4 and SDI-TD-DMUX-4 modules to transport up to 8 SD-SDI channels over one 3GHD link. High performance optics for short and long haul applications available, including CWDM and DWDM. Optical and electrical 3GHD TDM outputs are available simultaneously from the multiplexer cards, if purchased with an optional laser. Change-over functionality between de-multiplexer electrical and optical inputs. The transport signal is compliant with the SMPTE-425M Layer B standard and will always be marked as 1080/30P. Standard 3GHD infrastructure can be used to transport the multiplexed signal. Multicon interface allows remote control, status monitoring, error reporting and SNMP support. The HD-TD-3GMX-2 and HD-TD-3GDX-2 can be field upgraded to the SDI-TD- 3GMX-5 and SDI-TD-3GDX-5 respectively if the need arises. nevion.com 4

Microcontroller HD/SD output 1 HD/SD output 2 Remote Control Figure 2: Logical building blocks for the HD-TD-3GDX-2(-R) The HD-TD-3GMX-2 board embeds up to two independent HD or SD video streams in one output 3G stream. After the two HD or SD streams have been remapped, to avoid synchword conflicts with the transport stream frame, they are embedded in a 2.97 Gbps (3GHD) stream in a proprietary protocol which is still compliant to the SMPTE and SMPTE Level B standards. In order to reduce latency, the streams are embedded asynchronously to each other and to the transport stream. The combined latency of the HD-TD-3GMX-2 and HD-TD-3GDX-2 boards is always well below 100µs. If the two HD streams were fully synchronous when entering the HD-TD-3GMX board, they can have individual phase shifts of several samples after being demultiplexed at the HD- TD-3GDX-2 end, but the clock frequencies will be the same as soon as the system has stabilized (after a few seconds). After demultiplexing in the HD-TD-3GDX-2 board, the data structure that was remapped on the sender side will be restored and the data rate (pixel clock) will also be restored to exactly the same rate as it was received on the HD-TD-3GMX-2 board. The 3G signal is seen and transported as a standard 3G-SDI Level B (1080/30p) video by external equipment. No other format can be set at the sender side of the link and no other format will be accepted at the receiver side of the link. An HD-TD-3GDX-2(-R) or an SDI- HD-3GDX(-R) board is required to reconstruct the two HD signals from the 3GHD at the receiving end. Note that frame synchronization or switching of the 3G transport signal should be avoided, as switching or repeated/deleted frames will cause severe signal failures in the recovered streams at the receiving end of the link. nevion.com 10

11 The HD-TD-3GMX-2 can receive any combination of two HD or SD video standards, synchronous or asynchronous. The HD-TD-3GMX-2 embeds timing information that the HD-TD-3DX-2 uses to regenerate the HD or SD signals with the same clock frequency as the original inputs. The two signals are treated as two completely independent streams, which means that there will be no cross-contamination of the other stream when one input goes missing or has inherent errors. The output from the HD-TD-3GMX-2 module is either electrical 3G-SDI according to the SMPTE 425M standard, or if an optional laser module is added, simultaneous electrical and optical 3GHD-SDI according to SMPTE If the customer has purchased an optional long haul or short haul receiver module for the DMUX side (in which case the DMUX module will have an R-L or -R appended to its name), there will be an option available to select either input manually, or to select between them automatically. 4.2 The SDI-TD-3GMX-5 and SDI-TD-3GDX-5 The SDI-TD-3GMX-5 has two distinct modes of operation, set by the user: Either the same two-input mode described above for the HD-TD-3GMX-2 / HD-TD-3GDX-2, or a mode with up to five inputs, where only the first one can be HD-SDI. The latter mode is really the same as the first, but with the addition of a 4xSD-to-1xHD software module from the SDI-TD- MUX-4. This means that the HD stream normally coming straight from input 2, will now be replaced with a multiplex of four SD-SDI inputs. This in turn means that input 2 can only handle SD-SDI input signals in this mode, not HD-SDI. The user selection of the two modes will prevent the possibility of overflowing the 3GHD-SDI carrier stream. On the de-multiplexer side of the 3G transport link, the card will be able to read control words embedded in the transport signal to determine which mode it should operate in. No user control is necessary on the de-multiplexer side. The SDI-TD-3GDX-5 fully supports input from both the SDI-TD-3GMX-5 and the HD-TD-3GMX-2, whereas the HD-TD-3GDX-2 will only be able to recover the signals for outputs 1 and 2 if fed a signal from an SDI-HD- 3GMX HD ancillary data limitations Because the total usable transport bandwidth in the 3G output of the multiplexer is slightly less than that of two full HD streams, a small number of samples must be dropped from the incoming horizontal blanking intervals. The active picture will never be affected. The number of samples dropped varies depending on the HD format as shown in Table 1. Samples will be removed from the tail end of the HANC, following a left-alignment of all valid packets. Given typical HANC payload size, such as required to carry AES audio, the sample deletion will have no impact as it will occur entirely in unused samples. In the case of an unusually full HANC, such that sample deletion would result in a fragmented HANC packet, the remaining fragment will be deleted to maintain SMPTE compliance. HANC data that are not contained within a valid SMPTE 291M packet are not guaranteed to be transported, and may appear as null or black values when de-multiplexed. There are no limitations to the active video area portion of the HD signal to be transferred this will always be restored to its original content at the receiving end of the link, as long as it is a valid video signal according to applicable SMPTE standards. nevion.com 11

13 5 Configuration and monitoring Both multiplexer and de-multiplexer cards are self-configuring in the sense that they will start working according to default factory settings once power and input signals are applied. HD-SDI or SD-SDI video standards will be detected and handled automatically. 5.1 Configuration Configuration parameters can be changed in two ways: via changes to the DIP switches or via the system controller Multicon GYDA. The lower DIP switch of the module is labeled OVR. If this DIP is set to the ON position, the module will not accept commands from the Multicon system controller, but will instead be controlled entirely by the position of the rest of the DIP switches. Multicon GYDA will however be able to monitor the module and retrieve the current configuration (this will be stored to enable hot-swap functionality with another module under Multicon control). Conversely, if the OVR switch it is set to the OFF position, the other DIPs are disregarded altogether and the module is under full Multicon GYDA control. As delivered from the factory, all DIPs should be in the Off position. The module will then be under Multicon GYDA control Configuring the multiplexers from Multicon GYDA The HD-TD-3GMX-2 product contains a subset of the features found in the SDI-TD-3GMX- 5. The description below contains blocks that will only be found on the full featured product, the SDI-TD-3GMX-5. The picture of the HD-TD-3GMX-2 configuration page is provided for reference, see Figure 4. Starting from the top of the page on the SDI-TD-3GMX, the following things can be set/adjusted: Card label: This field enables the user to set a name for each module (Actually, it s the slot in the frame, as the label will persist even if the card/backplane combination is replaced by a completely different module). The name will show up above the card type on the info page and on the configuration page, and it will also be shown as a mouse-over text when the mouse cursor is held over the card s icon in the pictured rack. Locate card: Flashes the 4 LEDs on the front of the module at about 0.5 Hz for the number of seconds the user specifies. This is intended to help find a card quickly in a large setup. Firmware upgrade: The firmware for the onboard microcontroller and the FPGA can both be upgraded, if needed. This red line only shows up if the Multicon GYDA system controller has found a folder containing Flashlink firmware files. Contact Nevion Support if you need an updated firmware. Mode of operation: (Stored setting) The multiplexer can work in two distinct ways. It can simply pack two HDs into one 3G stream, or it can pack 4 SDs into one HD before packing the resulting HD with another HD from input 1. In the first case, the 2 HDs can each be replaced with a single SD, but still only transport 2 channels over the 3G transport stream. This will be handled automatically. In the second case, the HD on input 1 can be replaced with an SD signal. This will also be handled automatically. The other 4 inputs will only accept SD, and any HD signal on these inputs will simply be ignored. The reason for splitting the operation into two modes can be seen when considering what would happen when the card was fed 2 HDs and 3 SDs simultaneously. It would obviously not be possible to transport all these signals over one 3G stream, so something has to be given priority over the other inputs. The key is really whether input 2 is HD or SD, so if this toggled between HD and SD, it would not only mean that one channel was unstable, it would also affect whether inputs 3-5 would be transported or not. Hence the user is made to make the choice. A corner case is when the mode is set to be HD/SD+4xSD and inputs 3-5 have no signal at all. In that case it is possible to transport an HD from input 2 (and it nevion.com 13

14 will be!), but it is a fragile state, as it will immediately be replaced with one or more SDs as soon they re detected on inputs 3-5. Input integrity 1 5: (Stored setting) The user can select which errors should be counted and which can be ignored. The CCS and YCS count settings work as a pair, meaning that both will either be counted or both will be ignored. If the user makes a change to one of these bits, the module assumes that the new setting should be applied to both bits. The web page will always be updated to show the actual setting. The CCRC and YCRC error bits also work as a pair. The available error bits are as follows: EAV End of active video error SAV Start of active video error LNUM Line numbering error (HD only) YCRC Luma CRC error (HD only) CCRC Chroma CRC error (HD only) YCS Luma checksum error CCS Chroma checksum error LOCK Lock error AP-CRC Active picture CRC error (SD only) FF-CRC Full frame CRC error (SD only) VS Video standard error Inputs 3-5, which are SD only, will not have LNUM, YCRC or CCRC errors available, since these only have meaning for HD. Laser: (Stored setting) The only setting available for the laser is power On or Off. All other settings should already be done at the factory. The laser module is optional. Boards with factory mounted laser will have -T appended to the module s name, and only they will display the laser block in the graphical user interface. nevion.com 14

17 5.1.2 Configuring the de-multiplexers from Multicon GYDA Figure 5: The SDI-TD-3GDX-5 configuration page in Multicon GYDA. Starting from the top of the page, the following things can be set/adjusted: Card label: See multiplexer description. Locate card: See multiplexer description. Firmware upgrade: See multiplexer description. Input select: (Stored setting, only available when an optional optical input is installed). This control is only available for boards with the optional optical input. Here the user can select to force the input to be taken from either the electrical or the optical input, or allow the card to automatically select between them. In manual mode there is no fallback to the other input available at all. In auto mode, there s always a fallback to the other input available, the user only has to select which input is considered the main input. The other is considered the backup. The input selector is always latching. This means that if the input selector has (for some reason) switched away from main to the backup, the selector will continue to stay in this position until either the user selects to push the latch reset button, or the backup disappears (at which point the logic will start to look for a valid input on either of the two inputs, but starting with the main input). Through the hold time and the latch time the user can select how long the module will cling on to a lost signal and hope that it will reappear, and how long a signal must be present before it is considered valid and stable, respectively. nevion.com 17

18 Integrity of 3G TDM input: (Stored setting) Sets the maximum error rate or the maximum number of errors that can be present before Multicon GYDA sets off an alarm. Also sets which types of errors should be counted and which should be ignored. See input integrity in the multiplexer section for a description of the error bits.

Has no effect without mounted pin diode module (optional). This DIP is only read at power up. See box below for full explanation of the factory reset function. This DIP is only read at power up. OVR is short term for Multicon GYDA override. None of the other DIP switches will be read unless the Control mode switch (marked OVR ) is in the Manual mode position (marked On ). A factory reset is a 3 step process: * Set Factory reset DIP to the On position and boot the card (The Control mode must also be set to Manual mode). * Remove power and set the reset switch back to normal position (Off) * Power up the card as normal. nevion.com 19

20 The operation of the card will immediately reflect the freshly loaded default settings. However, the card must be kept powered for at least 10 seconds to ensure that these settings are stored locally to be retrieved again at the next start-up. The card s operational environment must also be kept static during those 10 seconds (i.e. no change in incoming video standards, no commands issued). Failing to meet these requirements could result in an incomplete reset and require the user to restart the factory reset sequence. 5.2 Monitoring The information page for the multiplexer cards The information page shows a dynamic block diagram of the board and some additional information in text form. The block diagram updates with the board status, showing missing signals (by red crosses over the appropriate signal lines). The text table on the information page gives additional information not easily conveyed in a graphical manner. From the text table, we can read the following: Both cable equalizers are enabled ( Normal ), as opposed to Bypassed. None of the two reclockers has been able to lock to a legal input. That the reclockers are unlocked can also be seem from the two red crosses over the signal lines to the right of the reclocker boxes. When the reclockers are locked, the bit rate will be indicated. The error counter has found no errors for input 1 or 2 (at least not errors of the types that are set be counted). We can also tell that the voltages are reasonably close to their nominal values. If this were a board with the laser option, the table would display an additional line like this: Here we can see that the laser is powered and what kind of laser it is (wavelength, power and type). nevion.com 20

22 Figure 8: The MUX info page in Multicon GYDA The information page for the de-multiplexer cards From the text table, we can read the following: The electrical input has been manually selected. This (and the name of the module) also indicates that this board has the optional optical input installed. No carrier is detected on the optical input. The error counter has found no errors for the HD input (at least not errors of the types that should be counted). We can also see that the voltages are reasonably close to their nominal values (It is quite normal for the 5V supply to be 0.1V 0.2V under its nominal value). nevion.com 22

25 6 Using the cards with the SDI-TD-MUX-4 and SDI-TD- DMUX-4 The SDI-TD-MUX-4 can be used to multiplex 4 SD-SDI signals into a single HD-SDI. This HD-SDI signal can in turn be used as input to the HD-TD-3GMX-2 or the SDI-TD-3GMX-5. This means that is possible to embed up to eight SD-SDI signals on one 3G transport signal with the use of either two SDI-TD-MUX4 + one HD-TD-3GMX-2 or one SDI-TD-MUX-4 + one SDI-TD-3GMX-5. In addition, one SDI-TD-MUX4 + one HD-TD-3GMX-2 can effectively be used together as one SDI-TD-3GMX-5, but at a slight penalty in the power consumption and by using two rack slots instead of one. The de-multiplexer side should normally be a mirror of the multiplexer setup. Although the SDI-TD-DMUX-4 (and indeed the SDI-TD-MUX-4) has built-in matrices for routing ( shuffling ) the four SD-SDIs, it s not possible to do any routing on the HD-SDI level. nevion.com 25

26 7 Connections 7.1 Power connections Power is applied to the board via the backplane board, which in turn is plugged into the power distribution bus in the Flashlink rack. The HD-TD-3GMX-2 and SDI-TD-3GMX-5 boards both consume 5.0 W of power from the +5 V supply and 1.5 W of power from the +15 V supply. The HD-TD-3GDX-2 and SDI-TD-3GDX-5 boards both consume 3.7 W of power from the +5 V supply and 1.7 W of power from the +15 V supply. For all boards, this means that some power supplies will limit the number of cards per frame to less than 10 (a fully populated frame). Check the power ratings of the supply you plan to use! 7.2 Backplane All cards mentioned in this manual use the same backplane. The direction of each BNC port will depend on whether it is used with a multiplexer or a de-multiplexer board. Table below shows the signal directions for the SDI-TD-3GMX-5 board, with the directions for the SDI-TD-3GDX-5 in parentheses. The GPI I/Os consists of alarm signals for driving external alarm devices and one input to disable the laser output for the SDI-TD-3GMX-5/HD-TD-3GMX-2. See chapter Figure 11: The backplane, common for all cards mentioned in this manual. nevion.com 26

RJ GPI connections, RJ45 Table 4: Back plane connectivity Figure 12: Pin layout Pin number Multiplexer functionality De-multiplexer functionality 1 Card OK. This pin essentially follows the card s status LED: When the LED is green, the pin will indicate card OK. The pin will indicate NOT OK when the LED is yellow, that is when the FPGA is being loaded. 2 Input 1 present Output 1 present 3 Input 2 present Output 2 present 4 Input 3 present Output 3 present 5 Input 4 present Output 4 present 6 Input 5 present Output 5 present 7 Output OK. This pin follows the output LED: It will indicate OK when the output LED is green, which is when output is present and the laser not faulty. 8 Ground (GND) Table 5: GPI pin-out Input OK. This pin follows the LOS LED: It will indicate OK when the LOS LED is green, which is when input is present and taken from the main input. The polarity of the GPI pins is such that OK/present is indicated by a leading transistor connection to ground. Conversely, an error is indicated by high impedance to ground. 7.3 The main board There are also a number of connectors on the board itself. None of these are intended for the end-user. nevion.com 27

28 The rear end of the boards (with the connector that mates to the backplane) is towards the right side of the board. The boards must be mounted in a Flashlink FR-2RU-10-2 frame with dedicated backplanes. Avoid inserting the HD-TD-3GMX-2 or the HD-TD-3GDX-2 board into a non-compatible backplane, as this may cause electrical and/or mechanical damage to the main boards and/or the backplane.

The text is not printed on the front panel. Each module has 4 LEDs. The colors of each of the LEDs have different meanings as shown in the table below. SDI-TD-3GMX-5/HD-TD-3GMX-2: Diode \ state Red LED Orange LED Green LED No light Card status PTC fuse has been triggered, FPGA FPGA is being loaded, or Module FPGA loaded and module OK Module has no power programming has failed, or laser has failed has not been programmed HD1 Los/Lock No valid HD/SD N/A Locked to a valid Module has HD2 Los/Lock Output signal present No valid HD/SD signals present 3G output stream is missing (measured at the output serializer) SDI-TD-3GDX-5/HD-TD-3GDX-2: Mode of operation is HD/SD+4xSD, and the 4 SDs are neither all present, nor all missing Valid 3G output detected, but laser indicates an error Table 6 LED SDI-TD-3GM/DX-5 HD/SD signal Locked to a valid HD/SD signal, or all 4 SD inputs locked (depends on mode of operation) Valid 3G output detected and laser OK no power Module has no power Module has no power Diode \ state Red LED Orange LED Green LED No light Card status PTC fuse has been triggered or FPGA programming has failed or laser has failed FPGA is being loaded, or Module has not been programmed FPGA loaded and module OK Module has no power HD1 Stream HD/SD video stream empty or not present at all N/A HD or SD stream present and OK Module has no power nevion.com 29

30 HD2 Stream Input HD/SD video stream empty or not present at all Input not locked to a valid 3G signal HD video stream containing SDs is present, but the 4 SDs are not all present Input locked to a valid 3G signal, but it is a fallback signal (check main signal) Table 7 LED HDI-TD-3GM/DX-2 HD/SD video stream is present. If it is an HD containing 4 SDs, all of them are present Input locked to a valid 3G signal. If the setup includes two physical inputs, input is taken from main Module has no power Module has no power Exceptions for the LEDS: The locate command will make all four LEDs blink orange and off synchronously. The operation of the card will not be affected. If only the Card status LED blinks between orange and off, this means that the mounted DWDM module is either too hot or too cold to output the correct wavelength, and that the output has temporarily been shut off. If this occurs other than for a short moment immediately after start-up, the thermoelectric element on the DWDM module is most likely broken. Firmware upgrades will activate running lights on the LEDs after the firmware download has finished. Do not remove power to the card when running lights are active, the card is unpacking and installing the new firmware. The modules will automatically reboot after a successful upgrade. nevion.com 30

31 8.2 RS422 commands FLP4.0 required commands, common for MUX and DMUX cards Block Blk# Commands Example Response Control - -?? product name\ SW rev n.m\ FW rev r.s\ protocol ver 4.0\ Hello command. Note 1: No other commands will be available until the card has received this hello. Note 2: This command will also enable checksums. Note 3: Cards are designed to be hot-swappable. To sync with the start of a new command, the cards will wait for a <lf> character before looking for a valid command. conf 0 - conf 0 *too long to list* Configuration settings Retrieves the card's configurable settings. Each addressable block is represented by a single line. Dynamic status may be included in response, but is usually reported in info only. - - info info *too long to list* Dynamic status info Blocks with static settings only will usually not be included, see conf above. - - chk off chk off ok Checksum off If issued twice in succession, this command will disable checksums. Note: Responses will still have the checksums appended. NOTE1:? command turns the checksum on again - - locate on <seconds> locate off locate on 3 locate off ok Card locator This command will cause all the LEDs to flash for a user specified number of seconds. If omitted, the value <seconds> will be set to a default of 120 seconds. The flashing can be terminated at any time with locate off. - - address Address address <address> Card address This command will force the module to check and update its current rack and slot address. This is normally only done at start-up. - - filename filename sditd3gdx mfw filename sditd3gdx ffw <name>'.'<extensio n> Firmware update The <name> part must match the card's hardware and include a revision number, and the extension must be either 'ffw' for FPGA firmware or 'mfw' for microcontroller firmware. After running this command, the board will be ready to receive its new firmware in Intel-hex format. - - fin Fin ok Finalize Finalize the programming of the microcontroller. See description of the uc boot loader (separate document). nevion.com 31

32 Block Blk# Commands Example Response Control misc 0 - STATUS NOT AVAILABLE BY SEPARATE COMMAND, ONLY FOUND in conf 0 AND info RESPONSES! prog fin ' ' ovr ' ' err Misc info prog if the card is freshly programmed by the boot loader and the program is still un-finalized. fin is the normal condition. ovr if DIP-switch 16 is set to the ON position and the card is under DIPswitch control. Note 1: The info part of misc has additional functionality when locate is used: locating <remaining seconds>. This enables a visible countdown clock in Multicon GYDA, but is not a required part of FLP Normal control blocks for the MUX cards Block Blk# Commands Example(s) Response Control lsr 0 on off lambda <wavelen> lpwr <laser_pwr> type ( c t n ) lsr 0 off lsr 0 lambda 1310 lsr 0 lpwr 0 lsr 0 type c mtx 0 <input> <output> mtx mtx on type C 1310nm 0dBm size 2:1 <in1> <in2> pwr <nom>vnom <volt>v Laser control (MUX only) Only on/off is directly available from Multicon. The other commands does not affect the laser itself, they just provide a tool to set information about the laser fitted to the board.

The MUX board has one rcl block for each input. The 2-input mux cards only display 2 reclockers. vmon 0-4 reset vmon 0 reset vmon N cnt <errors> err msk <bit_mask> Video monitors (MUX) The vmon blocks 0-1 consist of an error counter for each HD input. Each error counter can be reset with its reset command. Which errors are to be counted is set for each error counter with its msk command. Legal bits are contained in 0x7FF for the HD inputs, and 0x7E3 for the SD inputs, see the chapter on Signal integrity for explanation on the bit values. The 2-input cards only display 2 video monitors. nevion.com 32

33 8.2.3 Normal control blocks for the DMUX cards Block Blk# Commands Example(s) Response Control cho 0 pri <k> pri <k> <l> pos man <k> pos auto latch reset t1 <hold_time> t2 <lock_time> cho 0 pri 0 cho pri 0 1 cho pri 0 2 cho 0 pos man 1 cho 0 pos auto cho 0 latch reset cho 0 t cho 0 t size 3 pri k,l auto t1 <hold time> t2 <lock time> size 3 pri k,l man m latch t1 <hold time> t2 <lock time> cho 1 size 3 pri k,l auto size 3 pri k,l man m Video input select pri: a prioritized list of inputs, used when change-over is automatic. The list can have 1, 2 or 3 entries, or levels. Manual mode is effectively the same as automatic mode with one priority level only, but has its own command. 0 = from electrical input 1 = from optical input t1 and t2: change-over doesn't happen immediately, as a precaution against glitches and unstable signals. The timers t1 and t2 let the user decide how long (in ms) we will cling on to a missing input before we consider it gone and move on to the next pri level, and how long an input with a higher priority should be present before we consider it repaired and switch back, respectively. No commands available. Included to show internal status and to update Multicon GYDA graphics. mtx 0 - mtx 0 size 6:1 <in1> Operating mode mtx 0 has no valid commands, it is only used to display the current configuration set from the MUX side. The values has the following interpretations: 0: HD+HD 1: HD+SD 2: SD+HD 3: SD+SD 4: HD+4xSD 5: SD+4xSD=5xSD pin (0) - pin 0 cd ncd Pin diode status (DMUX only) No control.

35 9 Laser safety precautions These are guidelines to limit hazards from laser exposure. Therefore this note on laser safety should be read thoroughly. The lasers emit light at wavelengths from 1270 nm up to 1610 nm. This means that the human eye cannot see the beam, and the blink reflex cannot protect the eye. (The human eye can see light between 400 nm to 700 nm). A laser beam can be harmful to the human eye (depending on laser power and exposure time). Therefore: Be careful when connecting / disconnecting fiber pigtails (ends). Never look directly into the pigtail of the laser/fiber. Never use microscopes, magnifying glasses or eye loupes to look into a fiber end. Use laser safety goggles blocking light at 1310 nm and at 1550 nm Instruments exist to verify light output power: Power meters, IR-cards etc. Flashlink features: All the laser module cards in the Flashlink product range, are Class 1 laser products according to IEC , and class I according to 21 CFR when used in normal operation. Maximum output power 1 : Operating wavelengths: 5 mw > 1270 nm 1 Max power is for safety analysis only and does not represent device performance. nevion.com 35
