Introduction / Overview

The SW-SB is an active repeater which will allow the T24 range of modules to span around obstacles

or increase range or coverage.

The connectivity module provides a battery holder for a pair of alkaline ‘D’ cells and has regulator circuitry

for an external power supply. The batteries can also be used to provide power in case of external supply

failure. The case is environmentally sealed to IP65.

The repeater will allow messages to be repeated once which can effectively double the radio range.

Adding more repeaters will not increase range but can increase coverage.
