1.Overview

1.1 introduction

E30-490T20S is based on originally imported SI4438 fro m
Silicon Labs, with transparent transmission available, TTL level
output with air wake-up
consumption). They feature half duplex and SMD interface. 490M
frequency, long wave length and strong ability of penetration and
diffraction. They are applicable in the industrial and living
environment like a plant or indoors.
The module features FEC (Forward
algorithm, which ensure its high coding efficiency & good correction
performance. In the case of sudden interference, it can correct the interfered data packets proactively, so that the re liabilit y
& transmission range are improved correspondingly. But without FEC, those data packets can only be dropped.
E30-490T20S strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
