3.16.3. TX_ON Indicator (TX_ON)
Note: This feature is not available on the HL7548.
The AirPrime HL7588 module provides a signal, TX_ON, for TX indication. The TX_ON is a 2.3V
signal and its status signal depends on the module transmitter state.
Refer to the following table for the status of the TX_ON signal depending on the embedded module’s
state.
