Page 66 Appendix C — Configuring the RS-232 Interface
Using RS-232C communications
RS-232C communications can be divided into two sections —
Operate mode and Reprogramming mode. See Appendix B for a
complete discussion of the Re-programming mode used with the
Electronics Module.
RS-232C
operate mode
In Operate mode the RS-232C port outputs the following data.
- DP C=XXXX
- DP F=XXXX
- RH=XXXX
- TMP C=XXXX
- TMP F=XXXX
The data output by the Electronics Module can be modified in two
ways. First, the user can customize the data output to some subset
of the above. Second, the user can type various letters to obtain
immediate output of a single parameter. See the Re-programming
mode in Appendix B for details.
In addition to the output data, the Electronics Module will also
output various status flags as shown below.
Some subset of these prompts will appear after the output data.
They will be displayed with every system update as long as they are
active. Each prompt is followed by a carriage return.
Status Flag Description
ALARM The alarm relay is activated. Disabling the alarm relay will
also disable this prompt.
CONTROL The Electronics Module is in control at a dew/frost point.
BALANCE The Electronics Module is in PACER or AUTO balance
mode.
SERVICE The system optics require service, cleaning, or adjustment.
COOL The sensor is in maximum cooling mode.
HEAT The sensor is in maximum heating mode.
SHUTDOWN The Electronics Module has shut down because of exces-
sive temperature.
