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 Transmitter 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 MT-
4R, and MT-4D series, as well as differences for base and repeater 
modules.
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.
