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.
Caution: If this radio is integrated into another product, the system integrator must make
sure that the FCC label is visible from the outside of the final product, or that the
external label provided with this device is placed on the outside of the final product. The
system integrator may only use antennas that have been tested and approved with this
radio to maintain the FCC approval. If a system integrator uses a non-approved antenna
they are responsible for obtaining their own FCC certification. The radio also requires
+5V source voltage. Any voltage higher than 5.5V will damage the radio.

Caution: The 9XTREAM has been certified as a mobile device as per FCC Section
2.1091. In order to comply with the FCC RF exposure requirements the 9XTREAM must
be installed with the antennas listed above and a minimum separation distance of 20 cm
must be maintained from the antenna to any near by persons. If the OEM integrates the
9XTREAM into their final product, where the final product is classified as a portable
device per FCC Section 2.1093 (less than 20 cm separation distance between the antenna
to any near by persons). The OEM is responsible for obtaining a separate authorization
on the final product.
The Radio uses an asynchronous serial interface with a start bit, stop bit and eight (8)
data bits at TTL levels for communicating with the host system. Using an RS232 driver
chip (such as a Maxim MAX232) the Radio can communicate directly to a standard
Serial Communications Port on a PC. See the section titled Demo Kit Instructions for a
tutorial to help get started using the 9Xtreme Radio.
9Xtreme Features:
• Frequency Hopping Spread Spectrum (FHSS) technology
• Secure over the air data encryption
• Resistant to noise and interference.
• 100mW transmit power
• Up to 25 mile (40 Kilometer) effective range (line of sight, 9600 baud)
• Broadcast (promiscuous) networking protocol – data sent to the RX pin on one radio
will be presented out of the TX pin of the serial port on all other radios that are within
range and have the same network identifier code.
