1. 9XTend‐PKG‐R™RFModem
The 900 MHz XTend RF Modem is MaxStream’s longest range drop-in
wireless solution. Out-of-box, the RF modem is equipped to sustain
long range wireless links between devices. Simply enter serial data into
one modem and the data surfaces on the other end of the wireless link.
The modem transfers a standard asynchronous serial data stream
between two or more modems. Its built-in RS-232, RS-485 and RS-422
interface allows for rapid integration into existing data systems.
