Remote Control Operation

GeneralRemote control input bits are opto-isolated and connectedby a logical OR function to the local switch settings. For
remote control set the corresponding local switches to“Remote”, "AC" and "H” and select the desired setting via
a bit-code at the corresponding digital inputs.
Mixed operation, e.g. local AC/DC setting and remotecontrolled gain setting, is also possible.
The switch setting “FBW / 10 Hz” of the lowpass signal
filter is not remote controllable.
