REPEATER AND BASE MODULES
Daniels MT-4D product line is separated into base and repeater
modules. There is different hardware, fi rmware and software for
the base and repeater modules. MT-4R modules are all repeater
modules, so no distinction between base and repeater is made. MT-
4D modules are referred to as either MT-4D Repeater modules or
MT-4D Base modules.
The MT-4D Repeater modules are capable of being connected in
a repeater confi guration or a base station confi guration with no
encrypting / decrypting capability (clear mode). MT-4D Base modules
must be used when encryption capability (secure mode) in a base
station confi guration is required. MT-4D Base modules have limited
repeat capability using analog audio paths. The analog audio repeat
path does not pass all digital information through the repeater (such
as NAC, TGID, encryption and data packets).
IDENTIFYING MT-4 MODEL NUMBERS
Being able to identify the series of MT-4R or MT-4D P25 module that
you have is critical for programming, and understanding capabilities
and operation of the equipment. The model number of the P25
receiver or transmitter can be found on the bottom of the front panel
of the receiver or transmitter module as shown in Figure 1-1. Figure
1-2 and 1-3 show the breakdown of the receiver and transmitter model
numbers.
