Operator Terminal Cabling
On the NCM, the Operator Terminal connection can be made to:
• Port 2 (RS-232), see Figure 16 and Figure 17
• Port 3 via a modem, see Figure 10
• Port 4 (RJ-12 connector via an NT Emulator cable), see Figure 14
• Port 4 (RS-232), see Figure 16 and Figure 17
Note that the Operator Terminal can be an actual VT100 terminal
(VT220), or a VT100 emulation program (for example, ProComm®
terminal) running on a PC. When selecting the Operator Terminal
software set, Port 4 accepts the Operator Terminal; it accepts no other
RS-232 device. (The NT cannot be used on an NCM running the
Operator Terminal software.)
Figure 14 shows how to connect the OT via the RJ-12 connector of
Port 4 using the NT Emulator Cable. Figure 16 shows how to connect
the Operator Terminal (VT220) from the 9-pin connection of
Port 2 or 4. (This connection requires a DB9 Female end for
connection to the VT220.) Figure 17 shows how to connect the
Operator Terminal from the 9-pin connection of Port 2 or 4 to either
the 25-pin serial port or 9-pin serial port of the PC or the VT100.
