OM In order to control the outputs from the host application the outputs must be configured using the OM command. A “1” bit in the mask will open the corresponding output channel for outputs from the IO command and a “0” bit will leave the channel controlled by the setpoint. Issuing the OM command without any parameters returns the current mask in the form OM:0011. Change the mask by issuing the IM command with the appropriate four-digit value in the form OM 0001.
NOTE: This command is called IM on other H&B devices.
