Integrators’ Reference Manual for ViewStation EX, ViewStation FX, and VS4000

Both endpoints in Pass-Thru Mode —Two stations set to Pass-Thru Mode behave as a null-modem between their respective externally connected devices. Data from the RS-232 port on one endpoint is pushed through the call to the other endpoint, and then transmitted to the endpoint’s RS-232 port. The data channel speed is dynamically allocated. The maximum data flow rate is based on the bandwidth of the call.

Because data throughput has priority over video throughput, video bandwidth may be restricted to support data requirements. Audio is not compromised.

Far-site endpoint in Control Mode—If the near site is set to Pass-Thru Mode and the far site is set to Control Mode, the far-site device acts as a slave under the control of the device connected to the near-site endpoint’s RS-232 port.

The following table summarizes the port operation based on the

RS-232 mode configured by each endpoint.
