Video Conferencing Data Stations
■ Cables:
— Two male/male EIA-232-D cables, 8 ft. (24 m), to connect the PORT
1 connectors on the 7500B data modules to the EIA-232/V.35
converters
— Two male/male V.35 DB-37 cables, 8 ft. (24 m), to connect the V-35
communication ports on the video codec to the EIA-232/V.35
converters
— Two male/male RS-366 DB-25 cables, 8 ft. (24 m), to connect the
RS-366 dialing port of the video codec to PORT 2 on the 7500B
data module
Figure 6–6 shows an example of a video conferencing configuration.
NOTES:
1. If you are connecting MLX telephones, omit both 440A4 terminating resistors.
2. The maximum cord length from the 7500B data module to the telephone is
80 ft. (24.38 m).
