REVIEWING THE TRACER 4206 REAR PANEL DESIGN
The TRACER 4206 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
T1A, T1B, T1C 
and
 T1D 
(RJ-48C jacks) for connecting to a T1 device
A
NTENNA
 (N-Type connector) for the antenna feedline cable
T
EST
 
(1/4” stereo jack) for
 
QPSK constellation test point
Ground lug for connecting to earth ground
RS-232
 (DB-25 female) for connecting to a VT100 terminal or PC with terminal emulation 
software
Figure 2 on page 26 identifies the various features of the TRACER 4206 rear panel. A detailed discussion 
of all interfaces (including pinouts, where applicable) follows the figure.

Antenna Interface
The 
A
NTENNA
 
interface (N-Type connector) connects to the antenna (customer supplied) using standard 
antenna feedline cable. When determining the cable specifications for your application, refer to Section 2, 
Microwave Path Engineering Basics (
Coaxial Cable on page 19) for a discussion on cable length and loss 
factors.
Fuse
The fuse holder, accessible from the rear panel of the TRACER 4206, accepts a generic 1 Amp, 250 Volt, 
2-inch slow-blo fuse.
RF LOW
Red (solid)
the RSSI level is below suggested minimum threshold.
TST
Amber (solid)
there is an active test being performed by the system or 
there is an active loopback.
