Basic format for control data

The transmission of control data from the computer starts with a STX signal, followed by the command, the parameters, and lastly an ETX signal in that order. If there are no parameters, then the parameter signal does not need to be sent.

Notes:

•If multiple commands are transmitted, be sure to wait for the response for the first command to come from this unit before sending the next command.

•If an incorrect command is sent by mistake, this unit will send an “ER401” command back to the computer.

•SL1A, SL1B, SL2A and SL2B of Command IMS are available only when a dual input terminal board is attached.
