RS-232 Connection (DB-25) — Terminal Use

The RS-232connector provides a female DB-25 terminal connection (wired as a DCE interface), which is used for terminal access to the TRACER 4106/4206 system. The RS-232port provides the following functions:

•Accepts EIA-232 input from a PC or terminal for controlling the TRACER 4106/4206 system

•Operates at 9600 bps

Table 2 shows the pinout. Wiring diagrams for connecting to the RS-232connector (for various applications) are provided following the pinout.
