RS-232 Interface

RS-232 Control Mode

In Control Mode, the ViewStationEX, ViewStat ion FX, or VS4000 is

under the control of the PC or other device connected to its RS-232

port.

RS-232 Pass-Thru Mode

Pass-Thru Mode allows two endpoints to pass data from one unit’s

RS-232 port to the other unit’s RS-232 port, using the H.320 call as

the connection. Pass-Thru Mode is a proprietary feature that is only

available if both endpoints are ViewStationEX, ViewStation FX, or

VS4000 systems. Pass-Thru Mode is available only in H.320 mode

(ISDN or V.35/RS-449/RS-530) calls. It is not available in H.323 (IP)

video calls or multi-point calls.

Note

When using Pass-Thru Mode, both endpoints must be set to the

same baud rate.
