Data transmission on "change-of-state" of inputs as well as integrity update transmissions.
The period for update transmissions is configurable. Data transmitted as bit stream data frame using a synchronous protocol with 16 bit CRC error checking. Automatic acknowledgment of error-free transmissions with up to 5 retries before communications fail is set.
Communications failure status may be configured as a digital output. Resetting of outputs on communications failure is configurable.
Transmission rates Radio 4800 bd Serial 9600 bd
Typical radio message transmission time 80ms
