QUERY COMMAND (“Q”)
The 5 byte command to request power supply status information is the Query (“Q”)
command.
The protocol for the Query command will be as follows:
The power supply will receive a Q command requesting information. If the
command is properly received with no errors detected, the power supply will return
the Response packet back to the computer. If errors are detected in the command,
the power supply will return an appropriate error message.
The format of the command is:
SOH Q Check1 Check2 <CR>
Entered at the keyboard:
Ctrl-A Q 5 1 Enter
Sent in ASCII coded hexadecimal:
01 51 35 31 0D
where the checksum, which does not include the SOH character, will always be hex
51, transmitted in two ASCII bytes representing 5 and 1.
