VAB700XD Series User’s Manual
4.1 Turn-On Procedure
To operate the video transmission system, connect power to the units. The green
indicator “POWER” on the front panel shows that the unit is properly powered.
The green LINK light on the receiver should be ON.
This indicates that the receiver is receiving a valid optical signal from the transmitter.
There are no adjustments to be made.
5 Maintenance and Troubleshooting
5.1 MAINTENANCE
There is no operator maintenance other than keeping the units clean and verifying that
the units are operating in an environment that is within operating specifications for
temperature, humidity and power.
5.2 TROUBLESHOOTING
Troubleshooting is the systematic approach to solving a problem. Each step must be
performed in sequence, or erroneous test results may be obtained.
The VAB700XD Series has one optical transmission indicator: LLINK. RLINK is
applicable only in bi-directional systems. Only the VAB700XD-R unit has an optical
detect status indicator. The LLINK always refers to the Optical Transmission Status of
the transmitter.
For example, if you are looking at the front panel of the VAB700XDR and the LLINK is
illuminated GREEN, this indicates that the VAB700XDR is receiving a valid optical
signal. If the RLINK LED is GREEN, this means that the remote end unit (e.g.
VAB700XDT) has a valid optical signal. For troubleshooting purposes LOCAL END
refers to the unit with the indicators you are observing and REMOTE END refers to the
unit at the other end of the optical cable.
