2.2 XR Transmitter Set Up
2.2.1 General Set Up Considerations
The XR transmitter should be located in an area that maximizes the propagation of the signal to the largest area in the
facility. The FCC license needs to be applied for and granted before the equipment can be set up and operated. The
channel switch setting on the back of the transmitter must match the channel authorized by the license.

Set the transmitter on the supplied shelf, if purchased, or on another rack or mounting device as desired. If the rack
mount option is used and the transmitter is mounted in a rack, the transmitter must be on the top of the rack and the
rack must not have a top cover or it will interfere with the operation of the transmitter.

For better transmission it is recommended that the XR transmitter be located a minimum of 3 feet above the floor and
away from large metal objects, such as lockers, cabinets, ladders, power distribution panels, communications or
computer racks, metal or shielded walls, etc. The antenna radiates in a circular pattern, therefore the coverage for an
area will be better when the transmitter is more centrally located than when the transmitter is in the corner of a
building. In a multi-story building, locating the transmitter nearer to the top of the building often gives the best
coverage.

2.2.2 Hardware Set up
Prior to plugging the supply into the wall outlet and the jack into the back of the transmitter, the following set up steps
must be performed:
must be performed:
1. Connect the 46” whip antenna to the top of the XR transmitter on the NMO antenna mount. Be very careful to
start the antenna base square and not to cross-thread the antenna base onto the connector. When connected
properly, the antenna base will seat flat against the transmitter case top.

2. Set up the time synchronization input for the transmitter to one of the following options:
a. If this is a GPS synchronized master transmitter, install the GPS receiver outside using the supplied
mounting hardware, or in a window near the transmitter if the GPS will not be mounted outside. The
GPS receiver should have a full view of the sky whenever possible to get the best signal and the quickest
synchronization time possible. NOTE – the GPS receiver will not receive a signal through Low E
Glass. Make sure the NTP/GPS switch on the back of the XR transmitter is in the GPS position. The 7-
Pin MiniDIN connector from the GPS receiver or extension cables must be plugged into the GPS IN
connector on the back of the XR transmitter.

b. If this is a satellite transmitter synchronized by a repeater, mount the repeater on the wall as far away
from the transmitter as possible. The transmitter/repeater combination should be located within receiving
distance of the master transmitter. You can determine if the repeater is receiving the signal if the master
GPS transmitter is broadcasting by powering up the repeater. After approximately 20 seconds, the green
LED on the repeater should be flashing indicating that it received the signal from the master GPS
transmitter. Make sure the NTP/GPS switch on the back of the XR transmitter is in the GPS position.

c. If this is a network synchronized transmitter with a wired network connection, you need only connect the
supplied CAT 5 patch cable to the NETWORK LAN connector on the back of the transmitter and then to
the RJ45 wall jack that was set up for the transmitter’s network connection. Make sure the NTP/GPS
switch on the back of the XR transmitter is in the LAN position.

is a wireless access point within receiving distance of the XR transmitter. Make sure the NTP/GPS
