Chapter 3: GTR 8000 Base Radio Installation
Description
NOTICE: The length of the cable
between the site controller and
the base radio should be no
greater than 30 ft.
IP interface connection to the site LAN
switch port for this channel or connection to
site controller B base radio port for this
channel. An optional SDM RTU device
connects to the site LAN switch that is con-
nected to this port.
RF coax to receive path for antenna A.
RF coax to receive path for antenna B.
This port is used for dual diversity for
TDMA.
RF coax to transmit antenna.
Provides secondary power to a convention-
al comparator for a conventional base ra-
dio, or to the site controller in an ASTRO
25 repeater site.
Connection to temperature sensor, allow-
ing for temperature compensated battery
charging.
Antenna relay and presence detect, exter-
nal circulator load temperature (external
wattmeter not supported).
Input from and output to a 48 VDC power
supply or backup battery. When AC power
is not available, the device switches to op-
erate from a DC source if the optional DC
power (8AWG; length 9 ft), CA01400AA is
ordered and installed. One end connects
into the Batt/DC port and the other end
connects into the DC source. The contacts
are 39-83503N02 (AMP #53880-2), the re-
ceptacle housings are 15-83502N01 (AMP
#53884-1) and the mounting ears are
07-83504N01 (AMP #53887-1).
3084869Y06 cable is used for a positive
ground system. 3084869Y02 cable is used
for a negative ground system.
Input from 120/240 VAC nominal power
source.
