1. Overview
This document describes the 228-3530 VEX IQ Smart Radio.
2. Operational Modes
The Smart Radio can be commanded to transmit, receive or be idle. It does not
simultaneously transmit and receive. The Smart Radio may be queried to provide internal
register contents.
3. Ports
The Smart Radio has one digital port to get power, ground, and digital information
to/from the Host. The Host controls the Smart Radio via a Serial Peripheral Interface (SPI)
bus and two interrupt lines.
4. Basic Operation
Power ON: The unit is on when power is applied to the digital connector. The default state at
Power ON is Idle. No RF activity is occurring during idle.
Control: The unit will be controlled by and submit information as queried by the Host over the
digital port.
Radio Operation: The unit will be controlled by commands from the Host over the digital port.
Data includes modulation, frequency, unique identifier imbedded in the RF message, power
level and Forward Link / Reverse Link selection.
