Command Formats cont.
Where "*" is the selected Recognition Character. You may select any ASCII table symbol from "!" (HEX address "21")
to the right-hand brace (HEX "7D") except for the caret "^", "A", "E", which are reserved for bus format request. "(nn)"
are the two ASCII characters for the device Bus Address. Use values from "00" to hex "C7" (199 decimal).
"ccc" stands for the hex-ASCII Command Class letter (one of eleven given in table 3.12), followed by the two Hex-
ASCII Command Suffix characters identifying the meter data, features or menu items to which the command is directed
(given in table 3.13).
"<data>" is the string of characters containing the variable information the computer is sending to the meter. These
data (whether BCD or binary) are encoded into Hex-ASCII characters, two characters to the byte. Square brackets
(indicating optional status) enclose this <data> string, since some commands contain no data.
"<nn>" is the device address for RS-485 communication and the max is 199 in decimal.
Examples:
1. To reset the controller, send *Z02 (Table 3.1)
2. To read Setpoint 1, send *R01 (Table 3.2)
3. To change Setpoint 1 to 100.0
