4.2 Avoiding Pitfalls Using the 613T and 613R

If any of these problems occur, we recommend the following solutions:

If the display device shows only a black screen:

 Make sure that all the AC and DC plugs and jacks used by the external

power supplies are firmly connected

 Be sure that the BNC connectors are firmly plugged into the SDI source and the

display devices, and be sure that the transmitter and receiver modules are

correctly plugged into the source and SDI display devices, respectively

 Check if the SDI source and display are powered ON and properly booted

 Reset the system by unplugging and then replugging the transmitter SDI port

or receiver SDI port and then reboot the system

If the picture on the screen appears distorted or displays noise, check the quality

of the SDI source and the length of the optical fiber cable.

Caution:

Be sure that the fiber optic cables are always stored

and used away from liquid or dirt
