Description

 

The 915MHz Wireless Telemetry Module (GFSK90 ISM) is a small scale, low power 915MHz ISM FSK transceiver module. The low receive sensitivity (–118dBm) coupled with adjustable +5dBm - +20dBm output power ensures extended range and improved link performance over greater distances. Automatic antenna switching, frequency hopping spread spectrum (FHSS) and GFSK Modulation further extend range and enhance radio performance. This RS485 enabled telemetry module can be used to implement high-speed twisted pair RS485 communication links as well as facilitate collection, processing and logging of serially transmitted data which commonly requires improved noise suppression and cancellation. This module may be joined with our picLinkUSB modem (DCE) which can be used to facilitate a wireless DTE to DCE communications link.
