The following is a table outlining possible problems, symptoms, and solutions for Model 903:
SYMPTOM
No link ready lights
No diagnostics
No data and/or no
data LEDs
No Video
No video sync lights
at console
Console module
voltage reading low
Noisy video
Very bright video
•
PSU LEDs are on solid if +5, +12, -12 VDC rails are valid.
•
AIB-4 Data Direction LEDs: Red = Receive (into front panel); Green = Go (from front panel). A lit red LED at
one end of the system should have corresponding lit green LED at the other end of the system.
•
Only on during the space state (TTL = 0) and off during the mark state (TTL = 1); data activity is indicated by the
flashing or brightness of the LED. Idle signals are usually in the mark state (TTL = 1, LED = off)
•
FMB-VTX Link LED is on with valid downlink frames, including synchronization frames.
•
FMB-VRX Line LED is on with valid uplink frames, including synchronization frames.
•
FMB Video Activity LEDs (on with sync pulse present on each video channel)
•
Ethernet LEDs (on with valid link and/or collision)

Application Note
POSSIBLE PROBLEM
Non-functioning optical cable/damaged or
dirty connector
Optical loss is too high
Unit(s) not powered
One or both FMBs in wrong configuration
Cable not connected to console FMB
Cable not straight connection (DTE-DCE)
Program not installed or properly started
Improper channel configuration (also see no
link lights). Improper wiring of WAGO
connector. (RED LED = Data into Mux;
GREEN LED = Data out of Mux)
Data I/O board not connected at the remote
end (903-HD only)
Non-working data daughtercard
Improper channel configuration (see also no
link lights)
No video source at remote end
PSU internal 110/220 VAC selector switch
(bottom side of cassette) may be set
incorrectly (default is 110 VAC)
Partial LINK observable in diagnostics
Video signal input is too large

POTENTIAL SOLUTION
Change optical cable
Clean optical connections
Reduce optical loss
Apply power to modules
Configure both the same (e.g. MS/HS)
Install "straight through" RS-232 Cable
(EL-E0017)
Run 903-0406-00 VDM.exe and press
START button (see software manual).
Reference appropriate manual section
for data board configuration & wiring of
WAGO connector
Install ribbon cable at J5 of both HDB-
TX and DATA IO boards
Replace daughtercard
Reference appropriate manual section
for video and high density board
configuration
Plug camera into appropriate remote
video channel.
Set switch to appropriate AC input
voltage (110 or 220 VAC)
Inspect / clean / replace optical cable
system. Ensure valid ground connection
on video cables.
Ensure video input is 1.0Vpp
