8. Command and Response Structure
8.2 COMMANDS AND STRUCTURE
The meter responds to over 150 different commands from the computer. This section
gives the format and lists all commands by COMMAND CLASS and COMMAND SUFFIX.
8.2.1 READ COMMUNICATIONS CONFIGURATION COMMAND
To have the meter report its current communication parameters, the special command
“^AE” is provided when transmitted to the meter with the correct baud rate, parity
information, stop bit(s), and address (if multipoint). The meter will return 4 bytes
(9 characters including carriage return) of information as follows:
Byte #1 = Recognition character
Byte #2 = Meter address
Byte #3 = Bus Format
Byte #4 = Communications configuration
This “READ ONLY” command is the only one without a leading recognition
character.
Command Format:
^AE<CR> for point-to-point,
or
^AE[nn]<CR> for multipoint
where nn = device address from 01 to C7 (hex) = 01 to 199 decimal.
Response detail is given in Sections 8.8 and 8.9.
