1. 9XTend OEM RF Module
The 9XTend OEM RF Module was engineered to provide OEMs an
easy-to-use RF solution that provides reliable delivery of critical
data between remote devices. The module transfers a standard
asynchronous serial data stream, operates within the ISM 900 MHz
frequency band and sustains up to 115.2 Kbps data throughput.
