PIN DEFINITIONS
The AC4790 has a simple interface that allows OEM Host communications with the transceiver. The table below shows the
connector pin numbers and associated functions. The I/O direction is with respect to the transceiver. All outputs are 3.3VDC levels
and inputs are 5VDC TTL (with the exception of AC4790-1x1 and AC4790-1000 transceivers which have 3.3V inputs). All inputs are
weakly pulled High and may be left floating during normal operation (with the exceptions listed for the AC4790-1x1).

When ordered with a RS-485 interface (not available on the AC4790-1x1).
Must be tied to VCC or GND if not used. Should never be permitted to float.
If used, requires a shunt 0.1μF capacitor at pin 15 followed by a series 1kΩ resistor.

Session status if Protocol Status is enabled. Otherwise, generic output.
Transmitted data out of the transceiver
Non-inverted RS-485 representation of serial data
Data input to the transceiver
Mirror image of RS-485 A
Generic Input pin
Signal Ground
Has internal connection, for AeroComm use only.
Clear to Send – Active Low when the transceiver is ready to accept data for
transmission.
Request to Send – When enabled in EEPROM, the OEM Host can take this High
when it is not ready to accept data from the transceiver. NOTE: Keeping RTS High
for too long can cause data loss.
Received Acknowledge status pin if Protocol Status is enabled. Otherwise, generic
output.
AC4790-1x1: 3.3V, ±50mV ripple
AC4790-200: 3.3 – 5.5V, ±50mV ripple (Pin 10 is internally connected to Pin 11)
AC4790-1000: 3.3 – 5.5V, ±50mV ripple
AC4790-1x1: 3.3V, ±50mV ripple
AC4790-200: 3.3 – 5.5V, ±50mV ripple (Pin 11 is internally connected to Pin 10)
AC4790-1000: 3.3V ±3%, ±100mV ripple
Test Mode – When pulled logic Low and then applying power or resetting, the
transceiver’s serial interface is forced to a 9600, 8-N-1 rate. To exit, the transceiver
must be reset or power-cycled with Test Mode logic High.
Received Signal Strength - An analog output giving an instantaneous indication of
received signal strength. Only valid while in Receive Mode.
Generic Input pin
RESET – Controlled by the AC4790 for power-on reset if left unconnected. After a
stable power-on reset, a logic High pulse will reset the transceiver.
Signal Ground
When logic Low, the transceiver interprets OEM Host data as command data.
When logic High, the transceiver interprets OEM Host data as transmit data.
10 bit Analog Data Input
Has internal connection, for AeroComm use only.
When logic Low, the transceiver is in Session
RF Interface
Active Low version of UP_RESET. If RESET is used, UP_RESET should be left floating and if
UP_RESET is used, RESET should be left floating.
