RS-232 Connection (DB-25) — Terminal Use
The RS-232 connector provides a female DB-25 terminal connection (wired as a DCE interface), which is
used for terminal access to the TRACER 4108/4208 system. The
RS-232 port provides the following
functions:
• Accepts EIA-232 input from a PC or terminal for controlling the TRACER 4108/4208 system
• Operates at 9600 bps
Table 2 on page 29 shows the pinout. Wiring diagrams for connecting to the RS-232 connector (for various
