VAB700 SERIES START-UP PROCEDURE
1. Remove units from the box. Check for power supplies and AC power cords
shipped with the units.
2. Audio cards should have the associated terminal block adapter inserted in
each header. Consult the manual to ascertain the proper wiring configura-
tion. Wire each audio channel according to the pin designation in the
manual. Be sure to observe the (+) and (-) designation for balanced audio.
3. Use a standard 75ohm coax cable terminated in a BNC connector (e.g. RG 59U
with a BNC connector) to connect the video. Connect the video source to the
Video In BNC connector on the transmitter. Connect the Video Out BNC con-
nector on the receiver to the monitor.
4. Connect the fiber optic cables to the transmitter and receiver. Be sure that the
connectors on the cables are properly seated in the adapters on the units.
5. Attached the power supplies (shipped with the units) to the VABX Transmitter
and Receiver via the 3 pin terminal bloc pre-wired to the supply. Apply power to
the units using the 3 terminal AC Power cord.
Note: Apply Power to the Transmitter First. Then apply power to the Receiver. If there
is distortion in the Audio, recycle Power to the Receiver. (Due to the crucial timing
of digital circuitry, it is necessary to Power the Transmitter first, allowing the
Receiver circuitry to synchronize with the Transmitter timing signals.)
6.Verify all link and Video Presence status LEDs. Adjust all Video and Audio
input levels to within specification.
