classes: classes: “E”, and”Z” Command
classes:
Point-to-point mode Point-to-point mode Point-to-point mode
* ccc<data><cr> * ccc <cr> * ccc <cr>
Multipoint mode Multipoint mode Multipoint mode
* nnccc [<data>]<cr> * nnccc <cr> * nnccc <cr>
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.
“ccc” stands for the hex-ASCII Command Class letter (one of eleven given in Table 5.1),
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 5.3).
“<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 string, since some commands contain no data.
“<nn>” are the two ASCII characters for the device Bus Address of RS-485
communication . Use values from “00” to hex “C7” (199 decimal).
Table 5.3 and 5.4 shows the command letters and suffix for i-Series devices.
