The TWE-Basic (RAD-ISM-900-EN-BD/B) transmits Ethernet data from remote locations, even in high interference environments. The “basic” indicates the removal of the standard RS-232 and RS-485/422 ports. It is a “slave-only” device, so it must be used in conjunction with a standard TWE or TWE-BUS radio acting as the master. Like the other Trusted Wireless radios, the basic version features the MOTR-9™ radio platform, a 1 W frequency-hopping spread spectrum (FHSS) transceiver. It operates in the license-free 902-928 MHz ISM band. The MOTR-9 radio lets you configure over-the-air data rates up to 500 kbps. Adjustable packet sizes maximize data speed and minimize latency. The radio also incorporates selectable 128/192/256-bit AES encryption to prevent unwanted intrusion and keep data secure.
