Operator’s Guide DM-24 Digitiser

Issue G January 2003

GPS Type: The digitiser can utilize time signals from different sources. Options

available from GSL are Trimble GPS units (now obsolete), Garmin GPS units
or stream synchronization. In stream synchronization, time signals from a GPS
antenna or one of the radio time standards are sent via telemetry from a central
site to the digitiser. In order to synchronize with the time standard, the correct
option must be selected.
