Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
CDH Communications Introduction The 9XTREAM-192/96 radio is a 100-milliwatt frequency hopping wireless modem that communicates with other equipment using a standard 19200 or 9600 baud asynchronous serial data stream. The radio is half-duplex and can sustain close to a continuous data stream at the specified data rate. The 9XTREAM operates within the 900 MHz ISM Band under Part 15 of the FCC Rules and Regulations.
CDH Communications Connections The Data Radio is connected to a host device using the 11 pin and the 4 pin berg headers. These connections provide the radio with the required DC power source (+5V) and allow the Data Radio to be configured and provide the I/O lines for the asynchronous line level (TTL) RS-232 connection.
CDH Communications Operating States Scanning When the radio is neither transmitting nor receiving, it is continually scanning for valid transmissions. From the Scanning state the radio can either transmit, if data is presented on the serial port; or receive, if data is presented over the air. The radio will return to scanning when data is no longer present either on the air or on the serial port, or if a receive error is detected.
