Exhibit 8
The Data Radio is connected to a host device using a 20-pin dual in-line header. This
connection provides the radio with the required DC power source and allows the Data
Radio to be programmed, configured, and provides I/O lines for a TTL level RS-232
port.
Data is transported across the RF channel in a transparent, promiscuous mode. In
other words, data sent into the serial port on one radio will be presented out of the
serial port on all other radios that are within range and have the same group code.
Data verification and retries are the responsibility of the host (DTE) device.
The CIM board provides visual indication of operation and packet reception using on-
board LED indicators.
