LRM Radio Module – Host Interface Specification Introduction Document p/n: 9S02-7954-A501 Rev. A 2015 LAIRD Proprietary and Confidential Page 1-1 1. Introduction 1.1 Purpose A new family of RF module, the LRM family, is being developed by Laird. 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. 1.3 Applicability Applies to LRM family members, P/N 2PCA-7954-xxxx 1.4 Definitions, Acronyms 1.4.1 Definitions 1.4.2 Acronyms
LRM Radio Module – Host Interface Specification Features Summary Document p/n: 9S02-7954-A501 Rev. A 2015 LAIRD 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 Laird 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 Laird 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 Laird 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-A501 Rev. A 2015 LAIRD 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: 1 0 1 0 0 A9 A8 R/Wb7 b6 b5 b4 b3 b2 b1 b0  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)

A 2015 LAIRD 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 Laird FLASHBOX) to connect to a PC serial port. 21LRM, host interface26RXDTXD25!CONFIG3V3GND2722RS232 - TTL transceiver(ex: Laird FLASHBOX)3.3VDCRS232PC, running automated test program, or ANSI terminal emulation software*Note: The LRM !RX_EN, !TX_EN and !RESET all have internal pull-ups, so they can be left unconnected. 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].
