5.1.4 Port 3 RS422
Port 3 can be configured as an RS422 port. There are only two RS422 ports on the Nebula Control
Card (2445); if Port 2 is configured to RS422 Port 3 is not available. Default settings the frame is
supplied with give you
Port 1
RS422 Multidrop protocol
Port 2
RS232 Configuration
Port 3
RS422 General Switcher Protocol
NOTE: For Port 3 to operate as an RS422 port the following application “Reroute 2
nd
port / SDC Na-00743
SW-P-02 over IP” must be loaded onto the Beck Chip (SC12/SC13), this is done by default when the Pyxis is
shipped from Snell.
This allows Port3 to be used for General Switcher protocol ONLY. It also allows General Switcher over IP
operating in parallel with the serial connection.
As with all Snell control, any changes to crosspoint settings made by any control port or panel will be
broadcast to all other control ports.
