CONFIGURATION
This chapter describes the hardware and software configuration of the modem.
Note: All jumper settings are described in their appropriate tables.
3.1 Display/M&C
The Display/M&C PCB (AS/2305) is located on the front panel of the modem.
Figure 3-1 shows the Display/M&C card and the jumper locations. The jumper settings
are listed in Table 3-1.
All modem functions can be remotely controlled and monitored via an RS-485/
RS-232-C communications link. The 2- or 4-wire, half-duplex RS-485 interface makes it
possible to operate 1 to 255 modems on a common communications link. The RS-232-C
interface is used to communicate with a single modem.
The M&C module must be hardware configured to one of the two interfaces as listed in
Table 3-1.
