InterSense 900MHz Radio Module
(Part Number R69-00198)
User Manual
1. Overview:
The InterSense 900MHz radio module is used for real-time applications where it is
important to maintain low and predictable latency. The radio module is a low
powered device that operates over a frequency range of 906MHz to 926MHz
allowing up to ten radios pairs to coexist by using different channels.
The device has two antenna options that will be configured during manufacturing.
The device will be used either with a built in chip antenna or with an external strip-
line antenna that is connected through an MMCX type connector.
2. Technical Description
The radio section of the InterSense 900MHz Radio Module consists of an Atmel
ATZB-900-B0 Wireless module which consists of an Atmel ATmega 1281
microcontroller and Atmel AT86RF212 RF Transceiver. All radio configuration and
control firmware is programmed into the microcontroller and the user has no ability to
manipulate the operation of the radio.

3. InterSense 900MHz Radio Module Pin Definitions
A 6-pin surface mount connector is included on the InterSense assembly to allow
communication to and from the radio using the InterSense VSP serial protocol.
Power is also provided through this interface; the radio operates with an input
voltage range of 4-9Vdc. An on board voltage regulator reduces the input voltage to
3.3V for proper radio operation.
