CHAPTER 1: INTRODUCTION
This document is written as an introduction to Daniels Electronics
Ltd. MT-4R and MT-4D P25 Digital and Analog Radio Systems. The
document assumes the reader is familiar with conventional Two-Way
Radio Communications systems.
Chapter 1: Introduction

Project 25 is a standards initiative, to be amended, revised and added
to as the users identify issues and as experience is gained.
DANIELS MODEL NUMBERS
Daniels Electronics Ltd. has manufactured radio systems for more
than 60 years. In the early years, Daniels manufactured AM and
SSB radiotelephones for the marine industry, and more recently,
the MT series of radios for mountain top repeaters and base station
applications.
MT-2
The MT-2 series of radio modules were originally manufactured in the
1980s. This radio series was a crystal controlled analog radio system
capable of wideband (25 KHz) operation. Although systems are still in
operation throughout North America, this series of radio modules was
discontinued in the 1990s and is no longer supported.
MT-3
The MT-3 series of radio modules were originally manufactured in the
early 1990s. This radio series was available with both crystal controlled
and synthesized analog radio modules capable of wideband (25 KHz)
or narrowband (12.5 KHz) operation. The MT-3 radio modules were
discontinued in 2006, with the exception of the VHF Lowband and AM
products. For more information on the MT-3 series of radios, see the
Daniels MT-3 Analog Radio Systems User Guide.

MT-4
The MT-4 series of radio modules entered production during 2001.
This radio series is the P25 compliant digital narrowband radio
system, capable of analog (wideband and narrowband) or P25 digital
operation.
Daniels Electronics is committed to continually improving and
enhancing our product line. As the MT-4 P25 products evolve, the
hardware, fi rmware and software of the radio modules change. In order
to defi ne these changes, the MT-4 product line is further described
as:
MT-4R
The MT-4R series of P25 radios were manufactured from 2001 until
the end of 2003.
MT-4D
The MT-4D series of P25 radios were manufactured from 2003 until
the middle of 2006.
MT-4E
The MT-4E series are the current line of Analog and P25 modules.
DIFFERENCES BETWEEN MT-4R AND
MT-4D SERIES MODULES
The MT-4R and MT -4D modules are basically identical in operation, with
some advancements taking place in the RSS software programming
for the MT-4D (such as the ability to software program the squelch tail
on/off and timer). The only signifi cant difference between the MT-4R
and MT-4D is in the transmitter modules. The MT-4R transmitter was
not capable of being programmed for mixed mode operation. Mixed
mode is the ability for one transmitter channel to operate on either
analog or digital, based on the received signal. In order to simulate
mixed mode, the MT-4R transmitter was programmed with Bank A
as the analog channels and Bank B as the digital channels, and the
received signal simply switched between Bank A and B. The MT -4D is
capable of mixed mode, so Bank A and B can be programmed in either
analog or digital operation.
User
Guide
A P25 system can be comprised of both MT-4R and MT-4D modules.
For example; an MT-4R receiver and MT-4D transmitter can be used
to create a repeater, or an MT-4D link pair can be added to an MT-4R
repeater.

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. MT4D 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.

HARDWARE, FIRMWARE AND
SOFTWARE DEFINITIONS
Hardware
The hardware is the radio module itself. Daniels P25 Receiver module
hardware is comprised of a front end fi lter, an RF board (comprised
of a local oscillator, mixer and demodulator), and DSP and controller
boards and audio circuitry . Daniels P25 T ransmitter module hardware
is comprised of the audio circuitry, DSP and controller boards, RF
board (modulator), and RF amplifi er. The hardware for the different
MT-4 series is slightly different, using different chipsets in the MT4R, and MT-4D series, as well as differences for base and repeater
modules.
Chapter 1: Introduction

Firmware
The fi rmware is the programming that is contained within the radio
module. The fi rmware resides within the DSP and controller boards
and is programmed at the Daniels factory. The RSS programming
software can read the fi rmware version number of MT-4D modules.
The RSS programming software for the MT-4R modules is not capable
of reading the fi rmware version.
Software
The Radio Service Software or RSS is used to program features and
options. The RSS programs RF frequencies, modes of operation
(analog, digital or mixed mode), CTCSS, NAC codes, etc. The RSS
connects to a radio module using an adapter between the serial port
on a computer and the RJ45 interface on the front panel of the radio
module. There are different RSS versions for the different series of
modules as well as for base and repeater modules.
AVAILABLE FREQUENCY BANDS
The MT-4R and MT-4D modules were available in the VHF (136 174 MHz) and UHF (406 - 430 MHz and 450 - 470 MHz) frequency
bands.

JACKS
Daniels MT-4R and MT-4D Radio Equipment uses RJ45 jacks on the
Receiver, Transmitter and controller cards. These jacks have several
different uses, depending on the model series and confi guration of the
equipment. The receivers and transmitters each have two separate
jacks that are connected in parallel to signal lines inside of the module.
The jacks are labeled A and B and are identical.
On the MT-4R and MT-4D Repeater modules, the jacks are used
to connect the Receiver to the controller and the controller to the
Transmitter through RJ45 interconnection cables. The interconnection
cables carry Low Voltage Differential Signaling (LVDS) serial data
as well as analog and digital COR and PTT signals. The RJ45
interconnection cables are specifi c to Daniels Electronics equipment.
Do not use Ethernet or other manufacturers cables.
On the MT-4D Base modules, the jacks are used to connect to a
Motorola® KVL3000 or KVL3000 PLUS key loader, to load encryption
keys in the Receiver and Transmitter encryption modules. This
connection uses a custom Daniels cable from the key loader to our
radio.
On all MT-4R and MT-4D Receiver and Transmitter modules, the
RJ45 jacks are also used to connect the Daniels RSS programming
software. Daniels custom Radio Programming Interface Module
(RPIM) allows the serial port of a computer to communicate with the
receiver or transmitter for RSS programming.

LVDS SERIAL DATA
Daniels MT-4R and MT-4D Repeater modules use Low Voltage
Differential Signaling (LVDS) serial data to communicate between
receiver, controller and transmitter modules. MT-4D Base modules
do not use LVDS serial data.
A conventional analog repeater uses analog audio to communicate
between the different modules. Daniels P25 radio systems use serial
data between modules to allow for a completely transparent digital
path between the modules. This means that all digital information is
passed through the repeater system quickly and completely intact.
When a Daniels P25 Receiver receives a P25 digital transmission,
the receiver samples the incoming information and then creates
an LVDS serial data stream (of 257.8 kbps) that contains the same
information as the Common Air Interface (with some overhead data).
When a Daniels P25 Receiver receives an analog transmission, the
receiver samples the incoming information and then creates a serial
data stream (of 257.8 kbps) of the analog information. The incoming
frequency and deviation is converted to serial data through an A/D
converter. The transmitter uses this information to recreate the P25
digital or analog transmission.
DANIELS P25 DATA PACKET REPEATING
(OTAR, GPS, ETC.)
The P25 Common Air Interface (over the air signaling) supports
Voice Messages and Data Packet Units (confi rmed or unconfi rmed
data messages). Data Packet Units support Over The Air Rekeying
(for encrypted systems), GPS position information, and other data
applications.
Daniels P25 MT-4D repeater modules are capable of repeating the
P25 Data Packet Units. The MT -4D receiver and transmitter modules
must have fi rmware version 2.0 or higher to properly repeat Data
Packet Units. MT-4R modules are not capable of repeating Data
Packet Units.

MIXED MODE OPERATION
Mixed mode operation is used to allow the receivers and transmitters
to work in either analog or P25 digital mode without reprogramming
the radio.
A mixed mode receiver will receive the incoming FM or C4FM
transmission and will automatically detect and demodulate the signal
to an analog or P25 digital signal. The receiver will then output either
an analog or digital COR signal, as well as the appropriate serial data.
A mixed mode transmitter will accept the incoming serial data and
analog or digital PTT and will modulate the signal as either FM or
C4FM, based on its input. This allows the repeater to repeat both
analog and P25 digital signals.
The MT-4R and earlier MT-4D modules mixed mode response times
are slightly delayed compared to analog only mode or P25 digital only
mode. MT-4D modules with fi rmware version 2.0 or higher now have
the same response times in mixed mode as in analog only mode or
P25 digital only mode.
