Module
This section describes the 9111 Dual RS-232 Expansion Option Module. The
module is a two-port RS-232C serial interface card for the 9111 MultiPro series
unit. The module has two female DB-25 connectors (Port 5 and Port 6) and
occupies the same expansion slot as the Ethernet option card shown in Figure 2-4.
The interfaces for the module expand the capabilities of the 9111 to five ports. The
two expansion ports can be configured for either DCE or DTE by positioning the
jumpers located on the circuit board (see Figure 2-11). All other parameters are
configured through the console interface or through the NMCS program the same
as the other serial ports.
