4. REVIEWING THE TRACER 4108/4208 REAR PANEL DESIGN
Figure 2 identifies the various features of the TRACER 4108/4208 rear panel and Table 1 provides a brief
description of each interface.
Figure 2. TRACER 4108/4208 Rear Panel
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
applications) are provided following the pinout.
