5.5. RS422 Connections
5.5.1. RS422 Connector Pinout
The RS422 connectors are used to connect a remote control (from EVS or third party) to
your server.
The cable wiring is a straightforward pin-to-pin connection as illustrated in the following
diagram. You should use a shielded cable to avoid electromagnetic interference on long
distances.
Warning
The RESET command line from the remote control is sent through the pin 5 of
the RS422 connector. This function should be disabled when the controller on
connector #1 is not an EVS controller.
The technical specification for the RS422 link is as follows:
◦ 19200 bauds
◦ No parity
◦ 8 data bits
◦ 1 stop bit
5.5.2. Redundant IPDP Serial Link
The IPDirector communicates with the server via one serial link. If that link fails, the XS
server can no longer be controlled by any IPDirector.
A failover mechanism has been put into place: it switches the IPDirector link from one port
of an XS server to another port on another XS server.
