RS-232 Interface
RS-232 Control Mode
In Control Mode, the ViewStation EX, ViewStation 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 ViewStation EX, 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.
