LRM Radio Module – Host Interface Specification Document p/n: 9S02-7954-A501 Rev. 1. 1.1 Introduction A Introduction 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.
