A GPS Receiver is required when a Transmitter is set to use GPS as its time source.
Determine a suitable location for the GPS Receiver unit. Location is extremely important to ensure the best operation of the system.
GPS Receiver location
Must be mounted where it has a "clear view of the sky" to receive a GPS signal 24 hours a day.
Typical mounting locations include the inside of a window (not a Low-E glass window), to an exterior pole, or on a rooftop.
Must be kept away from large metal objects.
GPS Receiver and cable must be mounted above any potential standing water, snow depth, leaves or other obstructions and is protected from the weather.
10 ft. (3 m) GPS cable supplied. Extension cables available from Primex.
Transmitter with internal antenna: Maximum total distance of the GPS cable to the Transmitter cannot exceed 200 ft. (60.96 m).
Transmitter with external antenna: Maximum total distance of the GPS cable to the Transmitter cannot exceed 100 ft. (30.48 m).
GPS cable located outdoors: Cable routing to inside of building requirement 2 in. (5 cm) minimum conduit and weatherhead. Use of a GelWrap splice enclosure is strongly recommended.
GPS and extension cables connections must be weatherproofed.
Supplied Ferrite Bead is required to be attached to the GPS cable to prevent electromagnetic interference (EMI) between the Transmitter and GPS Receiver. Ferrite Bead should be located no greater than an inch from the end of the GPS cable – as near as possible to the Transmitter GPS IN input connection.
