2.1.4 RS-232 Computer Interface Setup
If your Control Unit does not have this capability, skip to Section 2.1.5 on page 2-12.
This available capability permits data output to, and gauge control by, a host computer. Output is
either by a command-response mechanism or by a talk-only mode which is invoked via a switch on
the RS-232 board. If you have this module in your unit, configure it to your system requirements by
setting the switches as directed in Section 2.1.4.1 on page 2-8.
A variety of baud rates and byte framing options are available, as well as switches to force the
handshake lines to an “always true” condition.
Stabil-Ion System RS-232 factory defaults are:
9600 BAUD, 8 data bits, no parity, 1 stop bit;
DCD, CTS, and DSR forced “true”.
The interface protocol is set using 8 switches. Refer to Figures 2-10, 2-11, and 2-12 for switch
numbering.
NOTE: Internal switches are read upon 370 power up. Changes in settings will take effect upon
next power-up cycle.
