Connecting a system terminal (or modem)
Options 51C, 61C, 81, and 81C terminal guidelines
During an installation, you can connect terminals to the CPSI ports for split
mode monitoring, or programming, or both. (Due to the speed of the system
messages displayed, personal computers are useful for file capture and
review.) Terminals connected to the CPSI ports can be installed as follows:
— one terminal connects to a CPSI port in one CPU (the cable is switched
from module to module as needed); one terminal is required in addition
to the terminal for the SDI port connection (see Figure 62)
— one terminal connects to a switch box that connects to a CPSI port in each
CPU: one terminal and a switch box are required in addition to the
terminal for the SDI port connection (see Figure 63)
— one terminal connects to a switch box that connects to an SDI port and to
a CPSI port in each CPU: one terminal and a switch box are required (see
Figure 64)
The Option 51C has only one CPU module and requires only one CPSI
terminal connection and one SDI port connection. A single terminal with a
switch box can be used.
Connecting a terminal to a CPSI port
Use the following procedure to connect a CPSI port directly (no switch box)
to a terminal (see Figure 62):
— Set the terminal to 9600 baud, 7 data, space parity, one stop bit, full
duplex, XON.
— Connect an NT8D95 cable to a matching connector on the terminal.
— Connect the NT8D95 cable to J25 on the I/O panel in the rear of the Core
or Core/Network Module.
— If you are using only one terminal for both CPSI ports, switch the cable
as needed. The terminal connected to the SDI port will always
communicate with whichever CPU is active.
