In standard mode, all possible sync sources will be made availble and usedfor autoSync operation. In remote mode, sync over power port will not be available as a sync source. Remote Device mode is where the AP or BHM timing port is connected to an SM or BHS timing port via a sync cable. In this mode, GPS data is unavailable and sync over power port shouldn't be used. If sync over power is desired, and a CMM or other sync over power device is in use, then select standard mode. This should really be named deviceType because this applies to both AP and BHM, but left this as apType for legacy purposes.
