n 64 sets of user-selectable pseudo-random hopping patterns,
intelligently designed to offer the possibility of separately
operating multiple networks while providing security, reliability
and high tolerance to interference;
n encryption key with 65536 user-selectable values to maximize
security and privacy of communications;
n built-in CRC-16 error detection and auto re-transmit to provide
100% accuracy and reliability of data;
n ease of installation and use – the MHX-920E module uses a
subset of standard AT style commands, very similar to those
used by traditional telephone line modems.
While the typical application for the MHX-920E is to provide a short- to
mid-range wireless communications link between DTEs, it can be adapted to
almost any situation where an asynchronous serial interface is used and data
intercommunication is required.
