Antenna
The radio must be installed within range of the trunk
system’s control channel. A high gain, Yagi-style
directional antenna is recommended for all installations.
Good coax design is required between the antenna and
the radio. In order to minimize phasing interference in a
Simulcast trunking system, the use of a Yagi directional
antenna is of utmost importance.
Placement
The radio should be placed where RF interference that may interrupt its RF
reception is minimized. Since there is rarely any need to touch the radio, there is
no need for the radio to be easily accessible.
Connection to the PC
The transceiver is connected to the computer using one of two methods.
•
If the transceiver has the Topaz Interface enabled, a TCP/IP connection
will be used to receive data from the radio. Standard networking
equipment and cables can be used to connect to the PC.
•
If the transceiver is connected via serial port, the EFJ Remote
Programming Interface (RPI) can provide a PC connection through the
PTT port on the front of the transceiver. At least one RPI is required to
program the transceiver.
A serial connection to the PC is completed by way of a DB9 RS-232 cable. If
necessary, this cable may be extended. A cable length over 50 feet (15 meters) is
not recommended. Use good data standards to decide if shielded cable is required
for a situation and RF environment.
Motorola XTL Series Digital Transceiver
Radio
The radio needs to be an RF-modem capable Motorola XTL series radio. System
monitoring requires a Millennium-enabled digital transceiver. The Motorola XTL
2500 and Motorola XTL 5000 are examples of these types of radios. The RF-
modem feature must be purchased from Motorola.
Power
Genesis offers a power supply for the Motorola XTL series radios. This power
supply includes a place to mount the Motorola XTL series radio. To ensure
reliability, an uninterruptible power supply (UPS) should be considered.
