CDR-9150 Data Radio

General Information and Labeling Requirements

This CDR-9150 is a frequency-hopping spread spectrum data transceiver operating in
the 902-928 MHz ISM band. The unit is designed to operate under Part 15.247 of the
FCC rules and regulations and is designed as an OEM module for integration into other
products or field devices. When installed using an approved antenna, the user need
only ensure that the appropriate FCC information is clearly visible on the outside of the
integrated product. This label should contain one of the following phrases to be
considered valid.

1. "Contains Transmitter Module FCC ID: PHO-CDR9150" or

2. "Contains FCC ID: PHO-CDR9150

For integration into products sold in Canada, the label should read as follows.
Contains Transmitter Module IC: 4315A-CDR9150

The term “IC:” before the certification/registration number only signifies
that the Industry Canada technical specifications were met.

Caution: If this radio is integrated into another product, the user is responsible for

complying with the external labeling requirements as directed in the FCC Rules and
Regulations Part 15.19. To avoid the need to obtain additional certification, the user
should only use antennas that have been tested and approved for use with this radio.

The unit operates on 50 discrete frequencies within the ISM band, each frequency
about 400 kHz apart. Using a frequency agile phase-locked loop synthesizer, the radio
is able to scan all 50 channels and quickly acquire synchronization with a transmitting
radio.

The radio is connected to a host device using a 10-pin SIP header. This connection
provides the radio with the required DC power source, allows it to be programmed and
configured and provides all I/O lines for an asynchronous serial interface.

CONFIGURATION

The CDR-9150 is supplied with an easy-to-use Windows98™ configuration program.
The configuration program allows the user to control the operation of their radio
network.

Installing

The configuration software does not require an installation. Simply run it from the CD
labeled “CDR-9150 Tools” or copy it onto another drive. Start the program by locating
and double-clicking on the “Programmer” icon. This will launch the configuration
program and display the screen below.

Click on the “PC Settings” tab, then select which COM port will be used to connect to
the data radio. As shown below, ports COM1 thru COM4 are available. This setting will
be retained the next time the configuration program is run.

Getting Started
To configure the radio, click on the appropriate tab for the radio being configured. Then

select the radio Communications Port. The default setting is for asynchronous serial
mode, UART (Universal Asynchronous Receiver/Transmitter). The default baud rate is
9600 bits per second. The interface baud rate can be set to standard values between
2400 and 57600 as shown on the following page. This mode supports 8 data bits, 1
stop bit and no parity.

Addressing

The radio has been designed to be very versatile in its addressing functions. Each radio
has its own identifier consisting of a group number and address number.

The Source Group specifies which group of radios the unit being configured belongs to.
The Source Address specifies the address within that group that uniquely identifies this
radio. The radio will decode packets containing a Destination Group and Address
matching its own. With the exception of broadcast messages, all others will be ignored.

Broadcast messages are those messages where the destination address is 0 and the
group is the same as the radio receiving it, or those messages where the destination
address and group are both 0. When the destination group is set to 0, all radios in all
groups will decode the packet.

Likewise, the Destination Group specifies which group of radios the transmissions will
go to. The Destination Address specifies the individual radio within that group that will
receive the message.

TX Hold Off Time

TX Hold Off Time sets the amount of time that must elapse after the last byte to be
transmitted is received by the radio before a transmit packet will be initiated. Setting
this value higher will prevent numerous small packets from being sent when the
transmit data is not continuous. The default setting will be adequate for most
applications.

Acknowledgement (Ack-Back™)

The CDR-9150 has powerful built-in path management features designed to make OEM
integration quick and easy. Activating packet acknowledgement will virtually guarantee
all data transmitted is received. Any packet transmitted by the CDR-9150 is then
acknowledged by the receiving radio. If any packet is not acknowledged, the
transmitting radio will resend the data. While reducing throughput, this feature also
handles missed transmissions as well as performs path management, allowing full
duplex communications.

The Retries field specifies the number of attempts the radio will make in trying to
resend unacknowledged packets. The Timeout field determines how long the radio will
wait for the acknowledgement before resending. (See Hardware Timing for more
information)
