Serial Port Configurations; Setup Menu For Com Ports - Octagon Systems XE–700 Reference Manual

Serial port configurations

COM1 and COM2 are dedicated RS–232C interfaces. They are always enabled.
COM1 uses address 3f8 and IRQ4, COM2 uses address 2f8 and IRQ3.
COM3 and COM4 can be configured as RS–232C, RS–422 or RS–485. The COM3/4
ports are enabled and configured in BIOS Setup.
If COM3 or COM4 are used for RS–422 or RS–485, and the XE–700 is at the end of
the network, these ports will have to be terminated. Switch 2 terminates the
network. The default setting is terminated. If the XE–700 is not at the end of the
network the switch must be set to unterminated.
The COM ports configurations are shown in Table 4–1. Tables 4–2 through 4–4
show the COM pin-outs for the COM ports, and Table 4–5 shows the switch
settings.
