Allows control of many types of radios operating in conventional analog networks and analog and digital trunking networks: EDACS, TETRA, MPT1327, DMR, IDAS, NEXEDGE. Hardware and software developed specifically for this purpose ensures the highest possible reliability. The controller can control radios from different manufacturers. Currently there are applied protocols of, among others, companies: Motorola Solutions, Yaesu, Vertex, Kenwood, Icom, SpectraEng, Hytera, Harris, TPRadio, Radmor and others.

Hardware

Minikom IP controller is manufactured in the form of modules installed in a 19” cassette of 1U height. One cassette accommodates 2 Minikom IP controllers.

HOT SWAP technology and the separation of the connection connectors from the printed circuit allows the replacement of a damaged component without the need to disconnect the connection cables or disconnect the power source. This superbly simplifies maintenance work.

Local operation

The controller is equipped with an LCD display, LEDs indicating its status, an internal speaker and a universal control knob. These front-panel elements allow quick diagnostics of the current status and signal possible errors in the operation of the controller and the control network. Using the control knob, quick configuration is possible without the need for an external computer.

If necessary, an external microphone can be connected, and with the use of the built-in speaker it is possible to actively conduct correspondence in the radio network with the possibility of changing the channel, talk group, volume, etc. In service mode, voice communication is possible between the controller and the dispatching station via IP network.

Supported radio communication protocols

  • The built-in DSP processor allows the controller to support multiple radio communication protocols regardless of the base radio used. A whole range of functions are available, such as, for example, encoders/decoders of various radio standards or signal intelligibility measurement algorithm.
  • Simplex and duplex operation
  • Built-in hardware VoIP codec (G.711, G.723, G.726, G.728, G.729)
  • Built-in CTCSS, DCS, invert DCS tone encoder/decoder
  • Built-in encoder/decoder for 5-tone signaling of all popular standards (including ZVEI, CCIR, EEA, EIA) with the ability to define user’s own standards
  • Built-in STQC signaling encoder/decoder of Digitex’s DSP system used in alarming Volunteer Fire Brigade units

Administration

The controllers are supplied with administration software for remote configuration and firmware replacement. Monitoring functions are extended to include an internal and external thermal sensor as well as the ability to diagnose the connected radio (available for selected radio models).

Status monitoring of the controllers is done via SNMP protocol.

The built-in VoIP codec allows the use of various formats for voice transmission using bandwidths from 8 kbit/s to 64 kbit/s.

Hardware features

  • Cartridge height – 1U for two controllers
  • HOT SWAP, possibility to replace the controller card without disconnecting the control cables
  • Internal temperature sensor and possibility to use additional external sensor
  • 3 general-purpose alarm inputs with indication of change of their status on dispatch consoles
  • Optional antenna path VSWR level sensor – antenna fault signaling on Unikom consoles
  • Internal speaker and microphone jack for local operation and service intercom
  • Built-in encoder/decoder of marine selective calling system DSC and ATIS signaling used in inland navigation
  • Receiving RSSI level (in analog and digital mode) and recognizing the level of speech interference
  • Audio signal delay for simplex-duplex operations, e.g. during RADIO<->TELEPHONE calls
  • Local recording of voice correspondence on a memory card

In response to customer demand, in 2017 we introduced the Minikom IP controller in a version that allows its installation on the local radio operator's station while retaining the ability to control this radio from the Unikom consoles of Multikom IP systems.

The controller is made in the form of a board for mounting inside the controlled radio (so-called "option board"). It is currently available for Motorola Solutions (DM4xxx series) and Hytera radios. The controller controls the radio's operation using the radio manufacturers' proprietary protocols. Basic information about the status of the controller is available on the displays of the controlled radios. The module is powered from the radiotelephone, and is controlled via an externally routed network connector.
