ii DOCUMENT CONTROL This document has been produced, verified and controlled in accordance with Daniels Electronics’ Quality Management System requirements. Please report any errors or problems to Daniels Electronics’ Customer Service Department. DOCUMENT REVISION DEFINITION Daniels Electronics Ltd. utilizes a three-level revision system. This system enables Daniels to identify the significance of a revision.
iii RF Exposure Warning Exposure to radio frequency (RF) energy has been identified as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed maximum permissible exposure (MPE) limits for field strength and power density, listed in FCC 47 CFR 1.1310 and IC RSS-102 Issue 2 Sect 4.

1 General Information NOTE: The General Information and the Theory of Operation sections are common for all models of MT-4E Receivers and Transmitters. Information that is specific to individual models will be identified where relevant. I n troduct ion P25 Digital Mode The MT-4E Receiver and Transmitter are FM radio modules capable of analog operation in 12.5 kHz (narrow band) or 25 kHz (wide band) channels. A firmware upgrade may be purchased to allow P25 Digital operation.
2 General Information Secure Communications The receiver and transmitter are capable of decoding and encoding secure communications if a DES‑OFB / AES Encryption Module is installed. To successfully decode or encode a transmission, the encryption module must be programmed with a valid encryption key using the Motorola KVL 3000 Plus Keyloader in conjunction with a Daniels Keyloader Cable. The Daniels Keyloader Cable plugs into the front panel RJ45 jack on the front of the receiver or transmitter module.
General Information C ha nnel and Bank Se l ec ti on Four channel select lines, CSEL 0 – CSEL 3, from the motherboard are brought into the receiver and transmitter modules by the 48-pin rear connector, allowing selection of 16 different channels. These signals are normally pulled low in the receiver and transmitter, but are typically set by jumpers on the motherboard to select Channel 1 by default. In addition, a bank select input is provided to switch between Bank A and B, each of which has 16 channels.

5 Radio Service Software Programming I n troduct ion NOTE: This manual contains general information about Radio Service Software (RSS). Software revisions occur regularly. For current RSS versions and instructions, refer to up-to-date help files on the Daniels Electronics website (www.danelec.com > Products > Software > Radio Service Software (RSS) > RSS Download Page). Once RSS is downloaded with either the full or demo version, click Help to access the help files.
6 Radio Service Software Programming Installation The RSS should install automatically once the CD is inserted. If not, run SETUP.EXE, located on the CD. NOTE: The receiver and transmitter must be programmed separately. Once the connections are made, the RSS may be run on the computer and the radio switched on. The first time a receiver or transmitter is connected, the USB drivers will need to be installed from the CD using the Hardware Update Wizard. To test the connection: 1.
7 Radio System Configurations R epeat er The MT-4E series receivers and transmitters may be configured in a repeater configuration. The standard way of setting up a repeater system is to connect the receiver to the transmitter through a Radio Interconnect Cable plugged into the RJ45 CNTL BUS connectors on the front panels of each radio module. This cable routes analog and digital COR / PTT signals and LVDS Serial Data from the receiver to the transmitter in both analog and P25 Digital mode.
8 Radio System Configurations An a lo g Fixed (Base ) Stati on In terface The MT-4E series receivers and transmitters may be configured in a fixed (or base) station configuration with an analog interface. An Audio Control Card or Base Controller is added to the system for E&M control. For tone remote control of the system, a Tone Remote Adapter is added to the system along with the base controller.
9 VHF & UHF Receivers and Transmitters The following section provides information that is primarily for VHF / UHF receiver and transmitter modules. For specific information on 700 / 800 / 900 MHz receiver and transmitter modules, see the 700 / 800 / 900 MHz section in this manual.
