Flow Control None
The serial interface supports a command line interface (CLI) which provides an easy-to-use means for
gathering basic information. The CLI is supported through any terminal emulation software. The terminal
should be set to echo locally so that typed commands are shown on-screen for ease of entry. The CLI does
not provide a prompt; instead, commands can be entered at a blank line. The CLI requires that all sent
commands be terminated with either a carriage return character (denoted <CR> in the following sections)
if the device is operating in Non-addressed Mode, or with both a carriage return character and a line feed
character (denoted <CR><LF>) if the device is operating in Addressed Mode. The terminal emulation
software should be configured to automatically translate transmit line endings (which occur when the “Enter”
key is pressed) into either <CR> or <CR><LF> as appropriate.
Commands
Each CLI command can be sent as either an Addressed Command or a Non-addressed Command.
Addressed commands include an RS-485 address, and can thus be targeted at a specific device if multiple
devices are connected to the same RS-485 bus. Devices will only respond to addressed commands if their
RS-485 address is between 0 and 6 (inclusive) and if their RS-485 address matches the address included
in the command. Devices will only respond to Non-addressed Commands if their RS-485 address is set to
7.
Note that addressed mode is not available if Ethernet option is present.
The command format for Addressed Commands is as follows:
<address>/<cmd><CRC><CR><LF>
Both a carriage return character and a line feed character are required for Addressed Command
termination.
The command format for Non-addressed Commands is as follows:
<cmd><CR>
Only a carriage return character is required for Non-addressed Command termination.
In both cases, the < cmd > string is a command word (in ASCII text) followed by zero or more sets of
parameter-value pairs. While the parameter-value pairs are required for some commands, a few commands
have optional parameters that may be omitted without triggering an error response.
For Addressed Commands, the <address>
value must match the device’s RS-485 address specified via
pins E, F, and K of the M&C connector. Addressed Commands sent to an address that does not match the
