The Wi.232 module combines a state-of-the art low power wireless transceiver with a powerful multipoint-to-multipoint protocol controller to form a transparent wireless communication solution capable of replacing wires in any RS-232/422/485 application. With a 120dB link budget and very low power operating modes, the Wi.232DTS module is excellent for AMR, RFID, Home Automation, and any other application requiring long range (<1500ft LOS) and long battery life (2 years from AA battery).

The module is designed to be totally transparent. No special addressing or formatting of data is required. Data is validated using an internally generated CRC-16 and encrypted using a proprietary encoding algorithm. Multiple modules can operate on the same channel because of the built-in carrier-sense-multiple-access (CSMA) protocol.

The transceiver operates in two modes: low-power and DTS. In low-power mode, transmitter output power is 0dBm and the maximum data rate is 38.4kbit/sec. In DTS mode, the output power is +12dBm and the maximum data rate is 152.34kbit/sec.

In DTS mode, the Wi.232DTS module is an excellent alternative to expensive and power-hungry frequency hopping modules. With 114dB link margin at the highest data rate, the Wi.232DTS will work farther and faster than any module in its class. Because DTS does not require frequency hopping, synchronization is very fast, allowing long duty cycles and very good battery power performance .
