Configuration of Serial Ports 3 and 4

B-4
The asynchronous serial ports (Serial Ports 1 and 2) are configured
permanently as data circuit-terminating equipment (DTE). The port
configuration is shown in
DB9 connector on the front panel of the processor board. A terminal for
may be connected to either the processor board or the transition
COM1
module, but not both.
The synchronous serial ports (Serial Port 3 and 4), are configured through
a combination of serial interface module (SIM) selection and jumper
settings. The following table lists the SIM connectors and jumper headers
corresponding to each of the synchronous serial ports.

Port 3 J6
Port 4 J24
Port 3 is routed to board connector J6. Port 4 is available at board
connector J24. Typical interface modules include:
❏
EIA-232-D (DCE and DTE)
❏ EIA-530 (DCE and DTE)
❏ V.35 (DCE and DTE)
❏ X.21 (DCE and DTE)
You can configure Serial Ports 3 and 4 for any of the above serial protocols
by installing the appropriate serial interface module and setting the
corresponding jumper. SIMs can be ordered separately as required.
