REVIEWING THE TRACER 4305 REAR PANEL DESIGN
The TRACER 4305 rear panel contains the following interfaces:
•
A
LARM
interface (terminal block) for connecting to an external alarm monitoring system
•
DC P
OWER
(terminal block) for connecting to a proper 21-63 VDC power source
•
DS3 I
N
and
O
UT
(BNC interfaces) for connecting to a DS3 device
•
Antenna (N-Type connector) for the antenna feedline cable
•
Ground lug for connecting to earth ground
•
RS232
(DB-25 female) for connecting to a VT100 terminal or PC with terminal emulation software
Figure 2 on page 27 identifies the various features of the TRACER 4305 rear panel. A detailed discussion
of all interfaces (including pinouts, where applicable) follows the figure.
