Connections
The DB-9 connector located on the front panel of each gateway Module is an RS-232 serial port.
The connector is employed to provide system trace and diagnostic routines for the individual
Modules. The MFIMs have one such port, which may be assigned for the desired function
(SMDR, ACD, etc.). Refer to the
iPECS Admin & Program Manual
.
The Phase 4 and higher Modules and PSU are set-up for 8-bits, no parity, and one (1) stop bit
running at 115,200 bps. To modify the speed and other settings, refer to the
iPECS Admin &
Program Manual
.
The RS-232 connectors for gateway Modules, POE8 and MFIM are terminated in a Data
Communications Equipment (DCE) configuration as displayed in Figure 4.5.1.8-1. The RS-232
connector in the PSU is terminated in a Data Terminal Equipment (DTE) configuration. Use a
cable pre-terminated with DB-9 connectors to connect an appropriate device (terminal, printer,
etc.) to the Module.
