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.

Chapter 1: Introduction

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.
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.
UG-001 Daniels MT-4R and MT-4D Radio Systems www.danelec.com
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).

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
5
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.
Guide
UG-001 Daniels MT-4R and MT-4D Radio Systems www.danelec.com
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.
