Troubleshooting

May 2008

Start with basic information:

What Model Number? What Power Supply? Fiber Type? Instruction Manual? Pin-outs

May 2008

May 2008

Things To Check:

LED Indicators: • OLI Optical Loss Indicator• VLI Video Loss Indicator• PWR Power Indicator

May 2008

Things To Check:

Transmission Distance? What Splices and Patches are in the system? Loss Budget (Calculated vs. Actual)

May 2008

More detailed troubleshooting:

Patch cords Proper audio balance Misaligned connectors 75 ohm video termination 120 ohm RS485 (RS422) data terminations Physical damage (Shock, water…)
