Overview
Built to perform in the field.
SATELLINE M3-TR9 is a compact 902–928 MHz frequency-hopping transceiver module designed for integration into OEM equipment. Its low-voltage CMOS-UART interface, small RF-shielded PCB and wide functional temperature range suit battery-powered, mobile and space-constrained systems.
The module provides a 115.2 kbit/s radio link with programmable output up to 1 W. User-selectable hopping bands, patterns, channels and frequency zones allow the radio plan to be adapted to the installation. In the United States and Canada, the 902–928 MHz ISM band supports license-free operation subject to the integration and RF-exposure requirements in the guide.
Configuration and firmware management are supported through SATEL NETCO DEVICE, SATEL Configuration Manager and SL commands. The integration guide covers the 20-pin DTE interface, power sequencing, antenna integration, mechanical mounting and host-product labeling requirements.
