Serial Ports 1 and 2

On the TMCPN710, the asynchronous serial ports (Serial Ports 1 and 2)

are configured permanently as data circuit-terminating (Figure 1-4)

equipment (DTE). The COM1 port is also routed to a RJ-45 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 J7 on the transition module must be configured to enable COM1

on either the transition module or the processor board. To enable the

COM1 port on the transition module, connect pins 2-3 of J7. To enable

COM1 on the processor board, connect pins 1-2 of J7.

Note If the J7 jumper is not present on the TMCPN710, the board

automatically enables COM1 on the MCPN750A.
