FCC Compliance Warning:
Changes or modifications to the 9Xtream Data Radio not expressly approved by CDH
Communications, Inc. could void the user’s authority to operate this product.
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. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
•
•
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1)
This device may not cause harmful interference, and
(2)
This device must accept any interference received, including interference that
may cause undesired operation.

Introduction
The CDH Communications 9Xtream Radio is a frequency hopping data transceiver
designed for integration with other products. 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 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.
• 140mW transmit power
• 20 mile (40 Kilometer) effective range (line of sight)
• Broadcast (promiscuous) networking protocol – data sent to 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. No two radios can transmit simultaneously, when one
radio is transmitting, all others on the network will await a pause in transmissions.

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 programmed, configured and provide the I/O lines for the
asynchronous line level (TTL) RS-232 connection.

Introduction:
Use this demo kit to experience the power and sensitivity of
the CDH 9Xtream radio. This radio transmits data at 19200
bits per second in the license-free 900MHz ISM band. See how
simple it is to communicate with the radio using asynchronous
serial communications by following the instructions below.

Test Connection
a. Place cursor in HyperTerminal window of Computer 1 and type a message. Notice that
text appears only in the window of Computer 2 and text typed on Computer 2 appears
only on Computer 1. This text is being transferred over the air by the CDH 9Xtream
radios.
b. Transfer the file RAT.TXT
i. On Computer 1: Select Transfer menu -> Send File(or try right-clicking in the
HyperTerminal window). Insert the disk into the A: drive and enter Filename:
A:\RAT.TXT Select Protocol: Ymodem (See figure 4). Press Send.
ii. On Computer 2: Select Transfer menu -> Receive File. Select a folder in which
to place the file and select Protocol:
Ymodem (see figure 5). Press Receive.
iii. The file will begin to transfer and any errors
or retries will be accounted for. Touch the
antennas and move the radios around to
notice that errors or retries do occur under
certain circumstances.
iv. When the transfer completes, open
Figure 4 – Send File Dialogue
RAT.TXT on Computer 2 and observe the
Box
pattern of text, it will be easy to see if any
characters were lost or corrupted.
v. Any file can be transferred this way. Use
either Xmodem or Ymodem protocol. Both
computers must have the same settings.
c. Try range testing by distancing the two computers
from each other. The radios can send and receive data
over 20 miles line of sight.

Dialogue Box
Problems (Trouble Shooting)
a. Can’t find the HyperTerminal on your computer?
i. Search your hard drive for HyperTrm.exe
ii. Download a free version from http://www.hilgraeve.com
b. Power LED doesn’t illuminate when battery clip is attached?
i. Replace the battery.
c. Cannot connect to the comm port or communication not working?
i. Try selecting another comm port by selecting Properties under the File menu.
ii. If necessary test the comm ports with a null modem cable (cross RX and TX)
between the two computers to verify operation of comm ports.
d. Some characters come through but not all?
i. Verify that both comm ports are set to 19200 bits per second.
