1. Internal AF Input gain is factory set for 1V
2. Carrier detect on RX1M mutes the AF and RXD outputs when RF input signal is <-123dBm.
3. There are no pullups on the open collector outputs. External pull-up resistor should be used.
4. With 1200baud modem mode enabled, parallel selection of channel is unavailable as the P1-P3 lines
distortion. Analogue gain may be set for an input level of 50mV – 2V
without appropriate test equipment. Contact factory for details
This can be factory disabled if required.

DC coupled input for 3-12V CMOS logic. Leave open if unused
AC coupled Analogue Input. Limit to 1V
<1.5% and peak FM deviation >2.5kHz (>2kHz for 60-65MHz)
DC supply. 75mA maximum drain. Only present when TXE is low
Ground
Parallel frequency select inputs. Inverted logic, 10k pullups to 4V
Function
DC level between 0.5V and 2.5V. 60dB dynamic range
Noise operated carrier detect. Open collector. ON/low = no signal
200mV
Open collector output of data slicer. Need external pull-up
DC supply. 75mA maximum drain. Present if unit is powered.
Ground
Serial programming/configuration input at RS232 level
Parallel frequency select inputs. Inverted logic, 10K pullups to 4V
Transmitter enable. Low = ON, open = off. 4k7 internal pullup to Vcc
