Page 174 of 456 Connecting a system terminal or modem
Terminals connected to the COM1 ports can be installed as follows.
1One terminal connects to a COM1 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 69 on page 175).
2One terminal connects to a switch box that connects to a COM1 port in each CPU; one terminal and a switch box are required in addition to the terminal for the SDI port connection (see Figure 70 on page 176).
3One terminal connects to a switch box that connects to an SDI port and to a COM1 port in each CPU; one terminal and a switch box are required (see Figure 71 on page 178).
Connecting a terminal to a COM port
Use Procedure 18 to connect a COM1 port directly (no switch box) to a terminal (see Figure 69 on page 175).
Procedure 18
Connecting a terminal to a COM port
1Set the terminal to 9600 baud, 7 data, space parity, one stop bit, full duplex, XON.
2Connect an NT8D95 cable to a matching connector on the terminal.
3Connect the NT8D95 cable to J25 on the I/O panel in the rear of the cPCI Core/Network Module.
4If you are using only one terminal for both COM1 ports, switch the cable as needed. The terminal connected to the SDI port always communicates with the active CPU.
