the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high
output indicates a transmitter fault caused by either the TX bias current or the TX output power
exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the
output is pulled to <0.8V.
MOD_ABS pulls line low to indicate module is plugged in.
Select is set at Bit 3, Byte 110, Address A2h. Tx Rate Select is set at Bit 3, Byte 118, Address A2h.
Note: writing a “1” selects maximum bandwidth operation. Rate select is the logic OR of the input
state of Rate Select Pin and 2-wire bus.
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
