COM1 and COM2 Asynchronous Serial Ports

On the TM-PIMC-0001, the asynchronous serial ports (COM1 and COM2) are configured permanently as data circuit-terminating (Figure 1-7) equipment (DTE). The COM1 port is also routed to an RJ45 connector on the front panel of the processor board. A terminal for COM1 may be connected to either the processor board or the transition module, but not both.

Jumper J11 on the transition module must be configured to enable COM1 on the processor board. If J11 is not configured, COM1 is automatically routed to PIM 1 on the transition module. Jumper J2 on the transition module must be configured in the same way for the COM2 port.
