Connecting the PC
Direct Local Connection
For a direct local connection, you must connect the PC to the system
programming jack. This is the lower modular RS-232 jack on the
processor module, as shown in Figure 1. (The upper jack is reserved for
the SMDR printer.)
To connect a PC more than fifty feet from the control unit, see Figure 2.
For direct local connections, the system supports speeds of 1200 and
2400 bps.
NOTE:
You must use a direct local connection to program in surrogate
mode.
