7.4 GENERAL FORMAT OF SCL RESPONSES
Upon receiving a valid command, an IMUX 2000 multiplexer, or to be precise the addressed CM4
Common Module, always responds initially with the line:
*OK
FROM NET ADDRESS=XX
This line indicates only that a valid command was received, and not necessarily that the multiplexer
itself is "OK".
If the received command is SET, UNLOCK, or LOCK, which do not require explicit responses, then
no additional response lines are generated. However, if the received command is CONFIG? or
STATUS?, then the "* OK" line is followed by one or more lines contain the requested information.
Examples of CONFIG? and STATUS? responses are included in the following sections.
If the received command is invalid (if, for example, it contains an unrecognizable command or an
invalid subaddress, or the user attempts to send a SET command while the remote port is locked), then
the addressed multiplexer responds with one of three invalid command response formats:
*WHAT?;
or
*WHAT? <descriptive message>;
or
*WHAT? <descriptive message> (rest of descriptive message);
In all cases, the last line of an SCL response, and only the last line, terminates with a semicolon (;). All
responses are immediately followed by a carriage return and line feed <CR> <LF>.
