:DATA carries the required information for the message
:
‘:’ (COLON) character is used to separate the header (ADDR CMD REG)
and DATA information.
DATA
Carries the information for the message. Some messages require no
DATA (e.g. Read Commands) so the field is optional.
Termination
Message termination is possible in two ways.
 : For normal communications that do not involve checksums use either a CRLF (ASCII 13, ASCII
10) as a terminator or a semicolon (‘;’ ASCII ). There is no start-of-message delimiter:
<Message> 
Ring Network Enhancement
Instruments with software revision V2.31+ can be configured in a Ring Network via a M42xx module
(software revision 1.01+). This requires the central computer to send additional framing characters,
‘Echo-On’ (=<DC2> =ASCII 12 H) and ‘Echo-Off’ (=<DC4> =ASCII 14 H) around each command.
Below is an example Ring Network command and response with two indicators:
COMMAND
<DC2>20110150:<CR><LF>
<DC4>
RESPONSE
<DC2>20110150:<CR><LF>
81110150:07/01/2030 17-29<CR><LF>
82110150:07/01/2030 17-30<CR><LF>
<DC4>
