78970 TRX module meets Part 90 of the FCC rules and regulations. Compliance with the labeling
requirements, FCC notices is required. In order to comply with FCC Certification requirements, the
Original Equipment Manufacturer (OEM) must fulfill the following requirements.
1. The system integrator must place an exterior label on the outside of the final product
housing the 78970TRX Module. The figure below shows the contents that must be included
in this label.
2. 78970 TRX modules may only be used with the antennas that have been tested and
approved for use with the module.
Labeling Requirements
The OEM must make sure that FCC labeling requirements are met. This includes a clearly visible
exterior label on the outside of the final product housing that displays the contents shown in
below.
WARNING: The 78970 TRX modules have been tested by the FCC for use with other products without

FCC Part 15.105(b) Warning Statement
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.
IC RSS-GEN, Sec 7.1.2 Warning Statement- (Required for Transmitters)
ENGLISH:
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more
than that necessary for successful communication.
FRENCH:
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain
de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante.
IC RSS-GEN, Sec 7.1.2 Warning Statement-
(Required for Transmitters w/ detachable antennas)
ENGLISH:
This radio transmitter (IC: 1007A-78970,Model Number: 78970TRX) has been approved by
Industry Canada to operate with the antenna types listed
below with the maximum permissible gain and required antenna impedance for each
antenna type indicated. Antenna types not included in this list, having a gain greater than
the maximum gain indicated for that type, are strictly prohibited for use with this device.
FRENCH:
Le présent émetteur radio (IC:1007A-78970, Numéro de modèle: 78970TRX) a été approuvé
par Industrie Canada pour fonctionner avec les types d'antennes énumérés ci-dessous ayant un
gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types
d'antennes non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué,
sont strictement interdits pour l'exploitation de l'émetteur.

1. Introduction
1.1 Purpose
A new family of RF module is being developed by Cattron. This family includes high-selectivity radios covering
several RF bands used world-wide for remote control applications. They are built around a common architecture,
and present a uniform host interface definition. The host interface is used for data communication and radio
configuration.
1.2 Scope
This document describes the host interface signal definitions, timings, operation mode, available functionalities, and
provide details about its integration to Unity products. This document does not cover RF specifications or power
supply specifications.

2. Features Summary
The ADL design addresses in first place Unity applications requirements. Its interface however is general enough to
allow compatibility to other legacy Cattron products.
Direct electrical compatibility to Unity RF interface – The interface is defined for natural integration to Unity
product line.
Data interface - support for synchronous and asynchronous serial link.
Stand-alone operation for production test – The ADL can interface almost directly to a PC serial port for testing
(no need for CPU board); only a TTL/RS232 translator is required.
These different aspects are covered in the rest of this document.
Figure 2.1 - ADL Module Block Diagram
The TCXO provides the reference frequency to transceiver chip
When the module is in RX mode, the RF switch is set to RX enable. The RF signal is sent to transceiver chip via
a bandpass filter. The transceiver chip will decode the rf signal to digital signal and pass to the control interface
When the module is in TX mode, the digital signal will be send to transceiver chip. After the RF signal will be
delivered through RF switch and radiated via either MMCX RF port or embedded PCB loop antenna

Document p/n: 9S02-7897-A001 Rev.A1
Laird Inc. Proprietary and Confidential Page 4-4
4. ADL Configuration Concept
All LRM configuration and status parameters are accessible through addressable registers.
- All parameters can be read in any of the following state: IDLE, RX, TX
- All writable parameters can be written in the following state: IDLE only
In order to facilitate adaptation to different platforms, the ADL configuration registers can be accessed using anyone
of three methods: I2C, SPI or serial asynchronous with ASCII strings.
The definition of the configuration registers is given in reference [3]. This section addresses the basic description of
all these three methods.
4.1 Stand-Alone Test Mode
The LRM can be operated in stand-alone mode for production/service tests. In this case, only a 3.3VDC supply is
needed, and a RS232/TTL transceiver (like Cattron FLASHBOX) to connect to a PC serial port.

*Note: The LRM !RX_EN, !TX_EN and !RESET all have internal pull-ups, so they can be left unconnected.
Figure 4.1 - ADL connection for stand-alone operation
The LRM will support several built-in test modes to ease testing from a PC. For example
a. Transmission Tests
- Generation of different type of carrier: unmodulated (CW), or modulated with “101010..” or pseudo-random
sequence
- Automatic generation of test RF frames with predefined content
b. Reception Tests
- Measure PER (packet error rate) when receiving the predefined test RF frames
- Measure RF input level
More details about the test modes can be found in reference [9P13-7949-A001].
