7 SMS 8104 Serial Digital Frame Delay Introduction The SMS 8000 product line consists of a 1RU frame which holds up to four modules. The modules provide such functions as video delay and format conversion. Modules are selected by the user to suit their particular requirements. The SMS 8104 Serial Digital Frame Delay Module is used to delay 525 and 625 serial component digital video. Features of the 8104 module include: Delay Adjust (Slow/Fast, Pixel or Line Steps, ±) Freeze Frame (2 Fields) Local or Remote (GPI) Control 8 Digit Program Delay Display (Line/Micro-seconds) (Serial Input) Signal Present LED Indicator The module has a user enabled (jumper select) automatic Freeze Frame circuit for those cases where the serial input TRS is not detected for 9 consecutive lines. The 8104 has a Freeze Field circuit (front panel select) that causes full frame Þeld 1 data to be output when selected. Auto Freeze Frame and Freeze Field modes are used for factory test only. Both modes generate video that does not comply with SMPTE 259M The 8104 module resides in a standard SMS 8000 one rack unit frame. SMS 8104 Instruction Manual 1

8 SMS 8104 Serial Digital Frame Delay Functional Description The 8104 provides a user adjustable delay of up to 2 Þelds for either 525 or 625 line component serial video data (270 Mbit per SMPTE 259M). At Þrst time power-up, the circuit is conþgured to minimum delay. Subsequent power-ups program the delay and conþguration set at the last power-down. Upon power-down, an EEPROM stores the delay setting, Freeze Frame/Field status, mode conþguration (525 or 625) and display contents. Delay adjustments are made using card edge delay increase, delay decrease, and shift momentary push-buttons. An eight-digit LED display indicates the program delay in Lines and Microseconds. A toggle switch allows the user to select between local (card edge) control or remote (GPI) control. A momentary toggle switch enables the user to select between Freeze Frame, Freeze Field, or Freeze Off modes.

Insert the module into the frame so that the left and right edges of the module slide inward between the card guides. 2. Press the front-panel retaining/ejecting tab in to lock the module in place. 3. Additional information concerning frame and power supply installation is located in the SMS 8000 Frame and Power Supply Manual. 4 SMS 8104 Instruction Manual

11 Installation Module Configuration SMS 8000 series modules are fully aligned at the factory and normally require no adjustments in the Þeld. If adjustments are necessary, they should be attempted only by qualiþed technicians using, at a minimum, the following equipment (or equivalents): Fluke 77 DVM Tektronix 2465 Oscilloscope or HP 5384A Frequency Counter GVG SMS 8000 Series Extender Card Source of SMPTE 259M Serial Digital Video Note SMS 8000 Series extender module, assembly , may be used to position a module outside the frame during adjustments. Auto Freeze Disable Auto Freeze Disable jumper P82 is used for factory adjustment. Insure that P82 is in the DISABLE mode. Figure 2 illustrates the setting and location of P82. DISABLE P82 Figure 2. P82 Jumper Setting Free Run Frequency Adjustment To adjust the Free Run Frequency follow the steps listed below. 1. Place the module on an extender board. (Allow 5 minutes to reach operating temperature.) 2. Remove input signal. 3. Set Jumpers P10 and P60 in the TEST position. See the Figure 3 for jumper locations. SMS 8104 Instruction Manual 5

Connect a frequency counter or a calibrated oscilloscope with frequency counter capability to TP Adjust R103 for a frequency of 27MHz ( ns period). 6. Connect a frequency counter or a calibrated oscilloscope with frequency counter capability to TP Adjust R629 for a frequency of 27MHz ( ns period). 8. When calibration is complete, set P10 and P60 to the NORM Operating position. GPI Remote The GPI connector on the back of the SMS 8000 frame allows (customer supplied) remote interface. Switch closures to GND on the GPI inputs allow delay and freeze control when the card edge Remote/Local switch is in the Remote position. 6 SMS 8104 Instruction Manual

GPI Pin Numbers and Functions Pin Number Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Signal GND Freeze Frame Freeze Field Not Used Not Used Pin 6 Shift Pin 7 Delay + Pin 8 Delay Pin 9 GND Front Panel Controls/Display The 8104 Front Panel consists of three momentary push-buttons, two toggle switches, a signal present LED, an eight digit LED display, and three test points; -5V, GND, and +5V. The front panel is illustrated in Figure 4. DELA Y Ð SHIFT DELA Y + RMT/LOC SIGNAL FREEZE OFF SMS 8104 FRAME DELAY PRESENT FRM FLD Figure Front Panel -5V GND Factory Test Mode +5V Delay is increased/decreased when pressing the indicated button. When <Shift> is pressed at the same time as one of these, the delay is increased/ decreased line-by-line. One momentary press of a button (or buttons) will cause a delay change of one pixel (or line). Continuing to press a button (or buttons) causes the delay to change at a smoothly accelerating rate until the button (or buttons) is released. The Freeze-Frame/Freeze-Field three-position momentary toggle switch allows the user to select between either Freeze Off (center position), Freeze Frame, or Freeze Field states. To select either Freeze Frame or Field, momentarily press the switch bat in the indicated direction. To disable, press again. When in the frozen state, delay adjustment is disabled. To cause a hard reset of the microcontrol logic, the <shift> button and Freeze- Field (Reset) switch are activated simultaneously. SMS 8104 Instruction Manual 7

14 SMS 8104 Serial Digital Frame Delay Freeze Field is used for factory test only. Freeze Field mode output video does not conform to SMPTE 259M (EAV/SAV Field bit set to Field 1). The second toggle switch (Þxed position) switches between local and remote mode. In local mode, the front panel controls are active and the GPI remote is locked out. In remote mode, the opposite is true. The 8-digit display consists of two four-digit dot matrix LEDs. The display reads lines of delay (4 digits) and XX.XX micro-seconds (4 digits, no decimal points) from left to right. The display indicates FREZ FRM, FREZ FLD, or AUTO FREZ when in those modes and is not blanked during remote operation or delay adjustment. Table 4 lists the displays that will appear for 1 second when the module is powered up or reset. (Displays with * only appear if the associated error occurs.) Table 4.

To change the format conþguration of the 8104 to operate in D1 serial 625 mode, follow the steps listed below: 1. Press SHIFT and FREEZE FRM simultaneously for 5 seconds. SEL CFG will appear on display. 2. Select Mode: Press DELAY Ð for Display will show Press SHIFT for Display will show To exit, press FREEZE FRM. Approximately 30 seconds later, the software will reset and the board will be reconþgured per your selection. 8 SMS 8104 Instruction Manual

15 Service Rear Connector The frame rear panel for each module consists of six BNCs, and one 9-pin D connector. Each module uses a unique overlay which labels the connector set appropriately for the function of that module. One BNC is serial input data, and 4 BNCs are delayed serial output data. The sixth BNC, is unused in this application. The 9-pin D connector provides GPI interface. Ensure that the rear connector overlay, on the rear of the frame, is in the correct location. Figure 5 illustrates the 8104 rear connector overlay. 8104/8204 SER OUT SER IN 8104/8204 Figure Rear Connector Overlay Service The 8104 Component 525/625 Serial Digital Frame Delay module makes extensive use of surface mount technology and programmable parts to achieve compact size and adherence to demanding technical speciþcations. Circuit modules should not be serviced in the Þeld. If your module is not operating correctly, proceed as follows. Check input signals Check cables and connections Check switch positions on front panel Check mode conþguration i.e or Verify source equipment is operating correctly Check output connections If the module is still not operating correctly, replace it with a known-good spare and return the faulty module to a designated Tektronix repair depot. Call your Tektronix representative for depot location. For jumper settings or adjustments, refer to the Module ConÞguration section of this manual. SMS 8104 Instruction Manual 9
