Smart Com Remote Diagnostics Manual - Rev 6

Smart Com Remote Diagnostics Manual - Rev 6 Chapter 1: Overview Varis' Remote Diagnostics (RD) allows you to remotely troubleshoot your Smart Com communication system via the mine's own local area network (LAN). This version of the software supports remote diagnostics for Smart Com 150/150IS, Smart Com 450/450IS and Smart Com Ethernet systems. Regardless of the size of the system, Remote Diagnostics can improve uptime and provide confidence in the system. Smart Com 150/150IS: All Smart Com 150 and 150IS amplifiers periodically send RD data back to the DRX located in the Base Station. software. Mine personnel can then simply point their web browser to the RD web server in order to view the status of the system. Smart Com 450/450IS: Smart Com 450 and 450IS amplifiers are polled using the RD web server software through a serial connection between the server and 450 Head End. Currently, amplifiers must be added to the system via the web interface to be polled. Future versions will automatically detect amplifiers installed along the leaky feeder network. Smart Com Ethernet: Smart Com Remote Diagnostics is also capable of showing CMTS (Cable Modem Termination System) and cable modem diagnostics for Smart Com Ethernet systems. The RD web server will periodically poll Ethernet devices using SNMP to retrieve diagnostic information. Key Benefits: Immediate notification of system faults (emailed alarms). The ability to pinpoint faults so that technicians can be dispatched directly to the problem area. System status can be viewed from any computer on the mine's LAN. Reduced need for expensive equipment to troubleshoot the Smart Com 150/150IS, Smart Com 450/450IS and Smart Com Ethernet systems. Chapter 2: Software 1 Requirements It's recommended that the Remote Diagnostic software be installed and run on Varis server hardware. Please contact us for more information. If alternate hardware must be used, the recommended system specifications are: Pentium 4 or equivalent processor. 2 GB of RAM. Windows XP, Windows Server 2003/2008. C:\Workspace\...\help\help_en.xml page 1 of 56

500 MB free disk space. Ethernet adapter. Serial port (only required for Smart Com 450/450IS systems) MS Internet Explorer 6+ (Javascript enabled). Administrator access to PC. 2 Installation The RD web server must be installed on a computer connected to the mine's LAN and must have a static IP address. Ask your IT Administrator for help in setting this up. 1. To install, run the "rdweb-setup-x.x.x.exe" file located on the distribution CD and follow the installation wizard. It is recommended that you use the default file locations. 2. The HTTP Port selection screen allows you to select which port the web server will run on. The default is port 80, but if you already have a web server running on port 80 (such as IIS), then you can chose an alternate port such as 3000. Please note: if you chose a port other than the default of 80, then you will have to specify the port number in the web address URL. For example, to access the main Remote Diagnostics web page, you would use the following URL: http://ipaddress:3000/amplifier/list, where ipaddress is the IP address of the web server PC. 3. The Site Name input screen allows you to enter the name of the site where the system is installed (i.e., mine name). 4. The System Type screen is used to select the type of Remote Diagnostics system; either Smart Com 150, Smart Com 450, or both Smart Com 150 and 450. This can be changed through the Administration interface later if incorrectly specified here. See Viewing Amplifier and Ethernet Data for more information. Note: It is important that the web server PC remain running at all times. This will ensure that all diagnostic data is displayed by the Remote Diagnostic web server.

see a screen similar to the one shown below: This screen shows a graphical display of cable modem diagnostic data over time. Using the check boxes along the top, you can control which fields are displayed on the graph (Downstream Power, Upstream Power, and Signal-to-Noise). You can also control the time period for which the data is retrieved by setting the Start Time and the Resolution. The Start Time can be changed using the calendar component shown below. This component allows you to select both the date and time. The Resolution is adjusted using the drop down box shown below. C:\Workspace\...\help\help_en.xml page 27 of 56

The resolution sets the interval for data retrieval. If you set the resolution too fine, you may get too much data to be displayed on the graph. If this happens, you must reduce the resolution until the data fits. Clicking the Live check box will provide a live view of the current Ethernet device data. The start time will be automatically offset based on the current resolution setting such that Start Time + Resolution = Current Time. This screen will automatically update every 10 seconds. You can also use the navigation arrows shown below to move the time range forward or backward by predefined amounts (10 minutes, 1 hour, 24 hours). The current time range is shown to the right of the arrows. 5 Configuring Amplifiers Varis' Remote Diagnostics allows you to order amplifiers such that it reflects the actual system layout. Each of the four branches on the main interface can contain a tree of amplifiers with subbranches (See Layout Example). Note: When a Varis amplifier initially reports in to the diagnostic receiver, it will be displayed under "Unassigned Amplifiers" until otherwise configured. MultiCOM amplifiers do not automatically add themselves to the unassigned amplifiers branch. Instead, MultiCOM amplifiers must be added before amplifier data will be displayed on the interface. Head end amplifiers with the latest firmware will be automatically added to the Head End branch. 5.1 Adding Amplifiers 1. To add an amplifier to the system, click on the Add Amp link next to the branch you would like to add the amplifier to. You should see a screen similar to the one below: C:\Workspace\...\help\help_en.xml page 28 of 56

The New Amplifier form has the following fields: Amplifier ID - The unique ID number of the amplifier you are adding to the system. The Amplifier ID must be in the form of 255.nnn.xxx for Varis Smart Com 150 amplifiers, 254.nnn.xxx for Varis Smart Com 150IS amplifiers, 100.nnn.xxx for Varis Smart Com 450 amplifiers, and 1.nnn.xxx or 5.nnn.xxx for MultiCOM amplifiers. Each number "nnn" must be in the range of 0 to 255 and each number "xxx" must be in the range of 1 to 255. Location - A general description of the amplifier's location. The Location field is optional but it is recommended that you enter a meaningful description of the amplifier's physical location. For example, "2300L Refuge Station". Branch - The branch you are adding the amplifier to. Insert - Where to insert the amplifier relative to another amplifier (defined by the "Amp" field). Can be one of "before", "after", or "as branch under". The Insert and Amp fields are used together to determine where the amplifier is to be placed in the tree. For example, "Insert before Amp 255.1.6" would insert the new amplifier before amplifier 255.1.6 in the tree. To simulate a splitter between amplifiers, you would select "Insert as branch under Amp 255.1.6" (See Layout Example). Amp - The related amplifier. 2. Click the Save button to commit the changes. The main page should now contain your newly added amplifier. Note: You can also add amplifiers by clicking on one of the buttons next to the amplifiers. This will automatically setup the new amplifier form to insert after the amplifier you clicked the button for. For example, clicking next to amplifier 255.1.6 will automatically preselect the Insert and Amp fields on the new amplifier form to read "Insert after Amp 255.1.6. This makes it quicker and easier to add amplifiers one after another. C:\Workspace\...\help\help_en.xml page 29 of 56

Chapter 7: Understanding Smart Com 150/150IS Amplifier Data The amplifier ID, location, RF downstream signal strength, RF upstream signal strength, attenuator setting, mode, voltage, and time since last report are displayed for each amplifier. Following is a description of these data reports. Amplifier Number: This is a unique 24 bit identifier which has been programmed into each amplifier (i.e., 255.0.100 - Varis, 1.68.108 - MultiCOM). The Amplifier ID must be a valid ID number in the form of 255.nnn.nnn for Smart Com 150 amplifiers, 254.nnn.nnn for Smart Com 150IS amplifiers and 1.nnn.nnn or 5.nnn.nnn for MultiCOM amplifiers. Varis amplifiers are indicated by a icon while MultiCOM amplifiers are indicated by a icon. Location: Down indicates signal presence and strength. In a properly functioning Varis system, RF Down can vary from -16 dbm (no signal present) to +6 dbm (signal present) for line amplifiers in a non-piloted system. The output signal strength during signal transmission can vary between +2 and +6 dbm (Varis line amplifier). Please note that Varis head end amplifiers have an output signal strength 5 dbm higher than line amplifiers. This information is available for both Varis and MultiCOM amplifiers. Up: This value shows the RF upstream signal strength (dbm). This information is available for MultiCOM amplifiers only ("--" is displayed for Varis amplifiers). Atten: This value is shown for Varis amplifiers only ("--" is displayed for MultiCOM amplifiers). This shows the Automatic mode, the attenuation applied by the CPU is displayed. While the amplifier is in manual mode, the Atten field shows the position of the manual attenuation switch (IC14) located on the amplifier board. An attenuation value of 0 db indicates that the amplifiers gain is at 100%. Alternately, an attenuation of 15 db indicates that maximum attenuation is being applied by the amplifier. Note: An attenuation of 5 db or more indicates that this amplifier has enough gain that it could possibly be moved further out along the Smart Com system. Contact a Varis technician for more information. Varis Modes: This data field indicates whether the amplifier is running in Automatic or Manual mode. The amplifiers mode setting is determined by the position of the mode jumper (JU30) on the front of the amplifier board. controlled by the position of the attenuation switch (IC14). C:\Workspace\...\help\help_en.xml page 41 of 56

MultiCOM Modes: MultiCOM amplifiers may display several modes depending on the position of the Mode jumper/switch and the Return pilot generation feature. Valid modes and their jumper/switch position are shown in the following table. MultiCOM Modes Mode IN IP BN Description Position 1 - This amplifier detects a Return pilot and has disabled its pilot generation feature (See Note 3). Position 1 - The amplifier does not detect a Return pilot and has generated its own pilot (See Note 4). Position 7 - This amplifier is in "Branch Mode" and is operating at maximum gain. Ensure 350 meter spacing is strictly adhered to. (See Note 1) RP Position 8 - This amplifier's Return pilot (175.000 MHz) has been enabled (See Note 2). NJ No jumper is installed. Immediate repair is required. **All other modes are factory settings and should not be used. Notes: 1. For any branch with less than 5 amplifiers, select jumper position 7. This will cause the amplifier to run at full gain and may increase the overall Return noise floor, but is preferable to having another pilot for the branch. This will reduce Return pilot noise in a MultiCOM system. 2. Enable the 175.000 MHz pilot tone for any amplifier at the end of a long branch (more than 6 amplifiers). 3. Always select jumper position 1 if the amplifier does not meet the criteria outlined in Notes 1 and 2. 4. Any MultiCOM amplifier in "IP" mode indicates that there is a cabling or pilot fault. Immediate repair is required. Voltage: This value indicates the DC Line voltage detected at the amplifier. Report: The number of minutes that have elapsed since the amplifier last reported to the DRX. A maximum of 24 hours will be displayed.

Chapter 12: Searching for Amplifiers You can search for a particular amplifier by typing the amplifier's ID number into the Find Amplifier search box and pressing Enter. If the amplifier exists in the system it will be highlighted in the amplifier list as shown in the screen shot below: Chapter 13: Updating Amplifier Firmware Smart Com 450/450IS amplifiers can have their firmware remotely programmed using the Remote Diagnostics web interface. When amplifiers are being programmed, the system will not receive new amplifier diagnostics data until the programming is complete. From the Administration menu, click on the Amplifiers tab and then select the Smart Com 450 tab. This will display the 450 amplifier list in a table as shown below: C:\Workspace\...\help\help_en.xml page 51 of 56

The amplifier table displays the amplifier ID, Firmware version, Board Revision, the Last Report time, and whether the amplifier is currently in Programing Mode or not. When an amplifier is being programmed, it is put into Programming Mode and can only respond to programming commands and thus will not respond to requests for diagnostics data. If the firmware update fails or the serial connection is interruped, the amplifer will remain in Programming Mode until is successfully programmed. Amplfiers that are in Programming mode are highlighted in red: 1 Select amplifiers Select the amplifiers to be updated by clicking on the checkbox next the amplifier ID. You can select all amplifiers C:\Workspace\...\help\help_en.xml page 52 of 56

in the list by clicking the checkbox in the header. 2 Select new firmware file Click the Update Selected button and then browse your computer's file system for the new firmware file to be used. 3 Update firmware Click the Update button to begin updating the firmware on the selected amplifiers.

If the firmware update was successful, you will see the following screen: Chapter 14: System Settings To access the System Settings page, click on Admin and then the System tab. C:\Workspace\...\help\help_en.xml page 53 of 56

On this screen, you can change various system settings. Each of the fields are described below: Site name: The Site Name is usually set to the name of the mine or tunnel where the system is installed. This is displayed along the top of every screen. System type: The System Type box is used to select the type of Smart Com Leaky Feeder system that is installed. 150, 450 or 150 and 450 if both types of systems are installed. UDP port: 150/150IS only - The UDP port is the port on the server PC used to receive data from the DRX unit and should be left to the default value of 4322 unless there is a conflict with another application. DRX alarming: If checked, this option will set the DRX alarm state on/off depending on the alarm state of the diagnostics system. COM port: 450/450IS only - The COM port to use on the server for serial communications with the Head End. Baud rate: 450/450IS only - The baud rate to use for the serial connection to the Head End. Poll delay: 450/450IS only - This value controls how long the system waits between complete system polls. If there is a small number of amplifiers in the system, this value should be increased to reduce the amount of time the amplifier spends responding to diagnostics data requests. Poll timeout: 450/450IS only - This value determines how long the system should wait to get a response from an amplifier. If the server is connected to the Head End via serial-ethernet convertors for example, there can be a significant delay in communications, and the timeout value may need to be increased. Increasing this value will cause an increase in the time it takes to do a complete system refresh (retrieve data from all amplifiers in the system). C:\Workspace\...\help\help_en.xml page 54 of 56

Chapter 15: Printing In order to generate a printable list of amplifiers click on the Print icon below the Find Amplifier search box near the top of the page. This will display the amplifiers in a printer friendly layout. To print this page go to the browser's menu and click File, then Print. It is recommended that the page layout be set to landscape in order for all amplifier data to fit on the page. Chapter 16: Frequently Asked Questions (FAQs) How often will each amplifier report to the diagnostic receiver? Each Varis amplifier will report in to the diagnostic receiver approximately every 4-8 minutes. This default report time varies between amplifiers to minimize data loss through transmission collisions. Why are all amplifiers being reported as Unassigned? Varis (not MultiCOM) amplifiers automatically add themselves to the UNASSIGNED AMPLIFIERS branch when they first call in (See Configuring Amplifiers). What are the differences between Varis and MultiCOM amplifiers? MultiCOM amplifiers have AGC (Automatic Gain Control) in both the Forward (Down) and Return (Up) directions. A MultiCOM system usually generates a pilot in each amplifier at the end of a long branch (more than 6 amplifiers). The combination of several Return pilots (175.000 MHz+/-100 khz) at splitters and at the Head End increases noise in the 172-174 MHz band and significantly reduces signal to noise ratio, thereby reducing cable range (350 meters). Varis AGC amplifiers do not require the generation or maintenance of pilot tones. Varis amplifiers can be used to replace the "main trunk" of MultiCOM amplifiers and the MultiCOM amplifiers can be re-deployed on smaller branches. This has the following benefits: No pilot required in the "main trunk" reduces Return pilot noise. Varis 500 meter spacing means fewer amplifiers, less noise and greater range from the cable. Local Diagnostic LED's show system status immediately without special training or tools. More consistent amplification of channels as Varis' 15 MHz Bandpass is completely flat over the 2.4 MHz MultiCOM operating range. Why does the DRX Status show a warning icon even after configuring the DRX? If the DRX Status indicates there is no communication from the DRX ( check: ), there are a number of things you should Make sure the network cables are connected and/or not loose. Check that the DRX is correctly configured for the network. Use the ping command to verify that you can "see" the DRX from the web server. Verify that you entered the correct Web Server IP address on the DRX. If you have a firewall running on the web server or somewhere between the web server and the DRX, you must configure it to allow UDP packets through on port 4322. For example, in Windows XP, open the Windows Firewall dialog from the Control Panel. Click on the Exceptions tab, then the Add Port... button. For the Name, enter "Remote Diagnostics UDP" and for the Port Number, enter 4322. Also make sure you check the UDP radio button. Finally, click OK to save the changes.
