5 PRODUCT DESCRIPTION

The M7200 mobile is a state-of-the-art radio that operates seamlessly between the 800 MHz frequency

band and the 700 MHz frequency band. The M7200 is designed to meet the critical communications

demands of public service users and complies with MIL-STD-810F specifications.

The M7200 is capable of supporting multiple operating modes, including OpenSky digital operation,

EDACS or ProVoice trunked modes, P25 digital trunked mode, P25 digital conventional mode, and

conventional analog mode.

The M7200 uses Time Division Multiple Access (TDMA) technology in the OpenSky mode to allow

multiple users to share a single RF channel. In addition, a single RF channel can support simultaneous

digital voice and data communications.

The M7200 provides integrated voice and data services. Voice operation is provided using a microphone

and speaker included in the radio installation kit. For data transfers, the M7200 is constructed with an

industry-standard RS-232 interface serial port for connecting an optional laptop PC.

A PC, not included with the M7200, provides network connectivity through the standard serial

(DCE-type) interface.

The M7200 has an integrated Global Positioning System (GPS) receiver. This allows the M7200 to fully

support the Automatic Vehicular Locator (AVL) for fleet management and dispatch applications.

The OpenSky M7200 benefits from a flexible, software-based digital radio design. Features and user

profiles are software-defined and can be reprogrammed over the air. The optional over-the-air

programming feature allows communication protocols to be changed easily and added at any time.

For remote mount installations configured with a CH721 control head, all normal radio operations and

interfaces can be handled via the control head connected to the radio unit by a single twisted-pair

connection routed through a vehicle. Up to six control units may be attached to a trunk mount radio. Each

control head provides a serial access point for data and any one (only one at a time) can be connected to a

data device such as a personal computer.

Where multiple control heads are connected or where a dash-mount radio is installed with additional

remote control heads, the following features are available from each position:

• Outgoing voice calls can be initiated. (Any control head can initiate a call but only one can talk at a

time. All other connected control heads will hear both sides of the conversation.)

• Incoming and outgoing audio can be heard. (Outgoing audio is not broadcast at the source position.)

• Independent audio control is available.

• Radio settings such as talk group, scan mode etc., can be controlled. (Any connected control head can

override the radio settings of other connected control heads.)

• Comfort settings, such as volume and display brightness that are applicable to the individual control

head can be adjusted and cannot be overridden by other control heads.

• An optional intercom function is available between control units. (Audio will be broadcast to ALL

connected control heads.)
