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.

= <Space> A1LO <Space> 500

Command List

These commands, represented by their respective ASCII characters, will

enable you to program the Series 942 from your computer. More detailed

descriptions of the commands are on the pages noted.
