Communication on the move
Communication on the move, with digital communication for the cab.
How to specify the Motorola mobile radio
The equipment is a MOTOTRBO mobile radio for installation in a vehicle or in a fixed position with adequate power supply. The official documentation publishes digital DMR and analog operation, numeric display and 16 channels. The correct selection begins with the frequency band variant. There are VHF versions from 136 to 174 MHz and UHF from 403 to 470 MHz. A unit does not work on both bands at the same time.
Power per variant
The published VHF versions work from 25 to 45 W at high power. The UHF versions work from 25 to 40 W. The low power configuration goes from 1 to 25 W. The highest number alone does not define the result. Antenna system, cable, connectors, position, frequency, terrain, obstacles and interference participate in the link. The proposal must record the variant and the planned installation.
Digital and analog
The radio can support a transition between analog and digital channels. The official data sheet publishes DMR and analog FM mode. In digital, the direct mode with two capacities allows two conversations on a 12.5 kHz channel when the configuration is compatible. Radio Management is optional. Transmission interruption appears as decoding. Optional features should not be described as present without corresponding programming and license.
Dimensions and protection
The chassis measures 44 by 169 by 134 mm and weighs 1.3 kg. The published rating is IP54 and the operating temperature ranges from minus 30 to plus 60 degrees Celsius. IP54 indicates limited protection against dust and splashes under test conditions. It does not equate to washing or submersion. The position must preserve ventilation, access to controls and integrity of connectors.
Installation planning
A vehicle installation includes power point, electrical protection, bracket, cable routing, antenna system and microphone position. The cable must not be under stress nor cross risk areas without protection. The antenna must match the band and be installed according to the vehicle. After assembly, the team must check voltage, reception, transmission and intelligibility with the engine under different conditions.
Documented accessories
The cards on this page present items with code and official image in the Motorola Solutions catalog applicable to the family: compact microphone PMMN4090, microphone with keypad PMMN4089, external speaker HSN8145, vehicle bracket RLN6466, DIN kit FTN6083, power cable HKN4137 and programming cable PMKN4147. Each item must be checked by reference and actual installation. Similar category does not replace documented compatibility.
Microphones and external audio
The PMMN4090 is the compact microphone. The PMMN4089 adds a keypad. The HSN8145 is a 7.5 W external speaker. The selection depends on the operating mode, cabin space and programmed features. A microphone with more keys does not create functions that the radio or configuration do not offer.
Mounting and cables
The RLN6466 is the trunnion bracket, while the FTN6083 is the DIN mounting kit. The HKN4137 is the published power cable, and the PMKN4147 is the front programming cable. These codes avoid choosing parts only by appearance. Before the proposal, confirm space, panel, power and access needed for maintenance.
Project checklist
- Identify VHF or UHF variant and corresponding power.
- Define digital and analog channels of the network.
- Map vehicles, routes and critical points.
- Plan power, fuse, bracket and ventilation.
- Select antenna and cables by band and vehicle.
- Confirm accessories by official codes.
- Test transmission, reception and audio after installation.
- Record configuration, vehicle, date and responsible parties.
Acceptance and maintenance
Acceptance must indicate vehicle, variant, power, antenna, cables, channels and installed accessories. Test in motion and at critical locations. In maintenance, compare power, antenna, cabling, microphone, speaker and programming separately. This record helps distinguish physical failure, network change and installation problem.
