The GPS antenna can be connected to the receiver at any time before or after the
receiver is powered on. Make sure the threaded collar turns easily when tightened
and is not cross-threaded.

GPS Receiver - Communication Module

The Z-Max requires that a Communication Module be connected whenever the unit
may be exposed to blowing dust or moisture. If the RTK base system is using UHF
radios, then an empty Communication Module housing (called V-Module) is required
to protect the Z-Max. If the RTK base system is using a cellular modem, then the
Communication Module serves as the modem transmitter.
The Communication Module connects directly to the left-hand side of the GPS
Receiver Module without cables. To connect the module, insert the small ledge of the
module into the rear of the GPS Receiver Module housing first as shown in Figure
3.4. This will correctly align the module. Using the ledge like a hinge, swing the
