A.1.4 Serial Interfaces COM1 P2200 and COM2
P2201/P2203
The CR9 offers two RS232 serial ports. All COM ports are accessible via the
Transition module at 10-pin headers and are software selectable for RS232 or
RS422/485 operation. The RS485 output drivers can be enabled or disabled with the
DTR signal. An active DTR means the drivers to be enabled. When using the RS422
setting the output drivers are always enabled and the DTR signal is not used. COM2
is also available at the rear panel with a 9-pin D-sub connector.
