4. REVIEWING THE TRACER 4206 REAR PANEL DESIGN
The TRACER 4206 rear panel contains the following interfaces:
• ALARM interface (terminal block) for connecting to an external alarm monitoring system
•
DC POWER (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
•
ANTENNA (N-Type connector) for the antenna feedline cable
•
TEST (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 ANTENNA 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.
