CDH Communications
Introduction
The CDH Communications 9Xtreme is a frequency hopping data transceiver radio
designed for integration with other products. The 9Xtreme operates within the 900 MHz
ISM Band under Part 15 of the FCC Rules and Regulations.
The 9Xtreme allows OEMs to integrate the radio into their own systems. When installed
using a CDH Communications approved antenna, the system integrator needs to make
sure the 9Xtreme’s FCC label, or a copy of that FCC label, is clearly visible on the
outside of the integrated product.
Caution: If this radio is integrated into another product, the system integrator is
responsible for complying with the external labeling requirements as directed in the FCC
Rules and Regulations Part 15.19. 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.

In order to comply with the FCC RF exposure requirements the Data Radio 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.
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.
