Operator's Guide
3 Operation
The CMG-RTM has two 10-pin bayonet connectors: one, on the right,
for attachment to a power supply (during synchronisation) or to a
digitiser (during operation) and one, on the left, for attachment to a
GPS receiver.
If the unit has been disconnected from power for some time, the
internal battery will be discharged. The unit automatically shuts
down under these circumstances.
The unit should first be connected to either a digitiser or power
supply, using the right-hand connector. The following screen will be
displayed:
The second line shows the date and time, according to the internal
clock. The third line shows that no GPS data are currently being
received.
A GPS receiver should then be attached to the left-hand connector.
The third line of the display will change to show that GPS signals are
being received.
