Elpro Technologies E2-450 Radio Module Instruction Manual CHAPTER 1 - INTRODUCTION The S2900 is a radio modem module that will be used as a base radio for a number of Elpro wireless products in the future. It will be primarily used to act as a wireless network adapter for transfer of 802.11 data frames over lower speed wireless links. The S2900 consists of a host microcontroller, an RF transceiver section, and a power supply section.

Elpro Technologies E2-450 Radio Module Instruction Manual SELECT MOSI Start Byte 0 Byte 1 BYTE_READY Radio TX data Lead-in SYNC Byte 0 Byte 1 End of Frame Data from Radio to Controller Data from the radio to the controller always consists of received radio data. Data transfer is initiated by the radio raising the BYTE_READY signal. The Controller then lowers the SELECT line, and transfers the data from the radio. The radio raises the BYTE_READY signal as soon as a radio lead-in is detected.

The Lead-in Found code is 0xFF.
Elpro Technologies E2-450 Radio Module Instruction Manual current channel then raises the BYTE_READY line to indicate to the controller that the RSSI data is ready. The controller then transfers the RSSI data from the radio with a second SPI transfer. Country Code Request If the Host Controller supports operation in multiple countries, the country code may be requested from the radio. The host controller sends the code 0xED (Request Country Code).

Elpro Technologies E2-450 Radio Module Instruction Manual CHAPTER 5 - Locale The S2900 radio is designed to operate in frequency bands 902 MHz to 928 MHz. These bands are fully supported for North America.
Elpro Technologies E2-450 Radio Module Instruction Manual CHAPTER 7 - Protective Earthing Point There are five mounting screw points around the cage, 4 of which are connected to the ground plane of the module. These should be screwed on with metallic screws to the metallic casing or ground points on the host system.
