8.9 GPS Unit
The 7035 terminal can support an optional GPS unit. This unit, a Garmin GPS
35HVS (TLX PN 30969), is a complete GPS receiver and antenna contained in a
small, water resistant package. The Garmin GPS 35HVS can track up to 12 satellites
at a time, while providing fast time-to-first-fix and one second navigation updates.
The GPS unit was designed to be used in conjunction with the Psion Teklogix
Powered Sled (Model 7937B), the Lithium Ion Battery Pack (PN 20605-003) and
the Psion Teklogix Port Replicator (TLX PN 21655). The GPS unit plugs directly
into the Port Replicator which supplies the GPS unit with power (from the Powered
Sled supply) and connects the data lines to the 7035 terminal.
The GPS unit should be mounted with a clear, unobstructed view of the GPS
satellites. For optimal performance, the GPS unit should be mounted in an area that
provides exposure to as large a swath of unobstructed sky as possible – a vehicle
roof is an excellent choice.
Important: Keep in mind that some windows have thermal and/or UV filter or
tint coatings that may shield satellite signals from the GPS
receiver.
Psion Teklogix provides four types of Garmin mounting brackets to secure your
GPS unit in position.
