Physical locations of the serial channels

The physical location of the COM1 and COM2 drivers depends on the link mode used
which, in turn, depends on the used communication hardware option. Serial channels
can be found on communication boards COM1004...COM1005.
• X7 is the fiber-optic interface. Only driver COM2 can be configured into fiber-
optic mode.
• X8 is the RS-485/IRIG-B interface. Both drivers COM1 and COM2 can be
configured to this interface: COM1 and COM2 can act as two RS-485 2-wire
links or, alternatively, COM1 can act as one single RS-485 4-wire link. Both ports
are galvanically isolated serial communication ports.
