ACKNOWLEDGING RECEIPT OF COMMANDS
Each request sent to the HV-CTL have by default two possible responses, an acknowledgement of a correct
request or an error response. The acknowledge response will be:
Ok<cr><lf>.
The HV-CTL may also be confi gured via command (see below) to suppress all responses. The user should
exercise care when confi guring no response as the user will obviously have no feedback as to the success of
the command.
ERROR RESPONSE
In the event an invalid command is sent to the HV-CTL, it will respond with the message "ERR: unknown
command". If an invalid parameter is sent to the HV-CTL, the unit will respond with the message "ERR: "
followed by the valid syntax for the errored entry.
Example:
A connect request with an incorrect input number:
CON 8<cr>
The error response would be:
ERR: CON <"1"|"2"|"3"|"4"|"5"|"6"|"7">|<"?"><cr>
Note that the returned error response may be expanded to a more detailed version by entering verbose mode.
This mode may be turned on by issuing a VRB Y command. The expected syntax for the command will be
returned, as above, and a description of each parameter.
For example, if verbose mode were turned on and the above command issued, the response would be:
ERR: CON <"1"|"2"|"3"|"4"|"5"|"6"|"7">|<"?"><cr>
