General Message
Syntax Example.
Example Format
For your benefit, we're presenting message/response examples with syntax
required for Series 942 communication. Information bracketed by < > indicates
a description, rather than literal characters. We show each ASCII character
that you must transmit to the Series 942, including space between the charac-
ters. (A "space" is itself an ASCII character, hex 20). For clarity, we also
represent each ASCII character as a hexadecimal pair. The pairs are spread
apart on the page for easy reading. However, electronic devices "see" the hex
pairs all together in "strings," with no spaces in between.
For instance, from the example just below, you want to set the Alarm 1 Low
(A1LO) parameter to 500°. Notice the syntax just below which uses the "="
command.
= A1LO 500
Command List
These commands, represented by their respective ASCII characters, will

descriptions of the commands are on the pages noted.
