Intercom communication for both crew members and Radio access for the commander
Easily installable with minimal set-up time required
Minimal training with user-friendly HMI (Human Machine Interfaces)
Up to four radios can be supported
Functional control of main features of radios (dependent on access permitted by OEM of radios)
Live intercom capability allows crew to perform other tasks simultaneously
Full duplex Intercom audio
RFI suppression circuitry significantly reduces effects of near vicinity high power RF transmissions
Functional Characteristics
The System “A” model is the basic Intercom/Radio system which comprises three units;
- Standard (SMCU) or Enhanced (EMCU) Master Control Unit
- Base Unit (BU)
- Power Supply Unit (PSU)
The System A is a wired intercom system normally for two crew members (Commander and Driver) who are directly connected to the MCU which in turn connects to the BU. The Driver is afforded Intercom only and the Commander has both Intercom and access to each of the installed radios (maximum of 4). The MCU provides control of the system plus control of the installed radios. The MCU, at a minimum, can provide channel selection, volume control and PTT functions. Inputting of frequencies and mode chan ges can be controlled depending on the access to protocols.
Intercom functions as follows:
- Mic mute (through keypad on SMCU)
- Live mic (through keypad on SMCU)
- Volume switch on front panel
- Intercom interupt for master position
- Intercom privacy
Radio functionality as follows:
- Radio PTT (through pressel on helmet assembly)
- Live radio select switch on front panel
- Monitor radio select switch on front panel
- Individual radio volume switches on front panel
- Channel select (through keypad on SMCU)
- Mode select (through keypad onS MCU)
- Radio precedence (through keypad on SMCU)
- Radio privacy
- Radio precedence
- Emergency Interrupt
- Other functions can be programmed in to suit
User requirements provided sufficient data on selected radio can be made available
