LRM Radio Module – Host Interface Specification Introduction
Document p/n: 9S02-7954-A001 Rev.A
Cattron-Theimeg Inc. Proprietary and Confidential Page 1-1
1. Introduction
1.1 Purpose
A new family of RF module, the LRM family, 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.

LRM Radio Module – Host Interface Specification Features Summary
Document p/n: 9S02-7954-A001 Rev.A
Cattron-Theimeg Inc. Proprietary and Confidential Page 2-1
2. Features Summary
The LRM 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.
• On-board CPU – The interface is controlled by an on-board Renesas CPU. This CPU controls also the details of
operation of the RF peripherals. This approach has several advantages:
a. Unified host interface definition – A single host interface can be defined for all LRM family members.
b. Low requirement on Host CPU resources – The on-board CPU takes care of most aspects of RF control and
timings. This allows releasing CPU resources (processing time, ROM/RAM space, hardware timers) that
become available for more features addition.
c. Simple Host device drivers - Most of driver firmware complexity is transferred on the radio CPU; the Host
device driver is much simpler, easier to test, and not as critical in regard to timings.
• Minimum buffers/Minimum Delay – Radio CPU firmware is implemented to provide a “almost transparent”
operation; transmission and reception delays are kept to a minimum
• Several interface modes – Several interface modes are supported in order to allow integration with other Cattron
legacy products:
a. Data interface - support for synchronous and asynchronous serial link.
b. Configuration interface - support for I2C, SPI and asynchronous serial access.
• Stand-alone operation for firmware download and production test – The LRM can interface almost directly to a
PC serial port for firmware download and for testing (no need for CPU board); only a TTL/RS232 translator is
required (such as Cattron flashbox).
• Support for advanced feature – The LRM family is designed to support advanced features such as FHSS
(Frequency Hopping Spread Spectrum) and Adaptive Channel Allocation, with minimal impact on Host
firmware.
These different aspects are covered in the rest of this document.

LRM Radio Module – Host Interface Specification LRM Configuration Concept
Document p/n: 9S02-7954-A001 Rev.A
Cattron-Theimeg Inc. Proprietary and Confidential Page 4-4
4. LRM 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 LRM 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 I2C
Signals I2C_SDA and I2C_SCL are used, according to the I2C standard protocol.
The LRM I2C configuration interface LRM emulates the behavior of the 1Kbytes I2C E2PROM found in all Unity
RF modules. This way, I2C operation is consistent for all Unity radios.
• Device Address: 0xA0 (same as other Unity RF modules)
• Device select code:
• Write operations: supports “Byte write” and “Page write”.
• Read operations: supports “Random Address Read” and “Sequential Random Read”.
For more details, refer to the M24C08 serial I2C E2PROM datasheet.
4.2 SPI
Signals SPI_PDO, SPI_PDI, SPI_CLK and SPI_PLE are used.
[TBD: Timings. (the LRM is a clock consumer)]
4.3 Console Interface
The serial interface configuration port is enabled by asserting !CONFIG signal; the serial interface is automatically
reconfigured in asynchronous mode, running at 38400bps, 8N1. All ASCII strings received are interpreted as
configuration commands. This mode is particularly useful for stand-alone testing, when the unit can be controlled
from a PC or by an operator/tester using a terminal emulation program.
4.3.1 “Write” command
wrCmd register value , where:
wrCmd = write command. w or wr can be used and are equivalent
register = register identification. Can use the register name or register address
value = value to be written, in decimal or hexadecimal format. Hexadecimal values are preceded by ‘0x’
Examples:
wr txf 915000000 : Write 915000000 to register txf (Tx frequency)
LRM Radio Module – Host Interface Specification LRM Configuration Concept
Document p/n: 9S02-7954-A001 Rev.A
Cattron-Theimeg Inc. Proprietary and Confidential Page 4-5
wr 0x80 18 : Write 18 to register address 0x80
wr txf 915000000 0x80 18: Concatenate the two writes above in a single instruction
4.3.2 “Read” command
rdCmd reg where:
rdCmd= read command. r or rd can be used and are equivalent
reg = register identification. Can use the register name or register address
Examples:
rd txf : Reads register txf (Tx frequency)
rd 0x80 : Reads register address 0x80
rd txf 0x80 : Reads registers txf and 0x80 in a single instruction
4.3.3 “Help” command
helpCmd where:
helpCmd= help command. h, help or ? can be used and are equivalent.
The LRM responds with the list off all available configuration registers.
4.4 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.
Figure 4.1 - LRM 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 [3].
4.5 Firmware Download
As shown in Figure 4.2, the LRM firmware can be downloaded using the Cattron FLASHBOX, as the rest of Unity
products family. A proper adapter needs to be used to fit to the LRM host interface connector.
