1. When ordered with a RS-485 interface (not available on the AC4490-1x1).
2. Must be tied to VCC or GND if not used. Should never be permitted to float.
3. If used, requires a shunt 0.1μF capacitor at pin 15 followed by a series 1k resistor.
4. If used, requires a series 1k resistor at pin 20 followed by a shunt 0.1μF capacitor.

Pin
• All I/O is 3.3V TTL with exception of 5V inputs on AC4490-200.
• All inputs are weakly pulled High (10k) and may be left floating during normal operation.
• Minimum Connections: VCC, VPA, GND, TXD, & RXD.
• Signal direction is with respect to the transceiver.
• Unused pins should be left disconnected.

When logic Low, the transceiver interprets OEM Host data as command data. When logic High,
the transceiver interprets OEM Host data as transmit data.

When logic Low, a Client is in range of a Server on same Channel and System ID. Always low on
a Server radio.
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.
