Industrial temperature version available (-40°C to 80°C)1.1.1.1. OverviewOverviewOverviewOverviewThe AC4490 is a member of AeroComm’s ConnexRF OEM transceiver family. It is designed forintegration into OEM systems operating under FCC part 15.247 regulations for the 900 MHz ISM band.The AC4490 is a cost-effective, high performance, 900 MHz frequency hopping spread spectrumtransceiver. It provides an asynchronous TTL level serial interface for OEM Host communications.Communications include both system and configuration data. The Host supplies system data fortransmission to other Host(s). Configuration data is stored in an on-board EEPROM. All frequencyhopping, synchronization, and RF system data transmission/reception is performed by the transceiver.The AC4490 transceivers can be used as a direct serial cable replacement – requiring no special Hostsoftware for operation. They also feature a number of On-the-Fly Control Commands providing theOEM Host with a very versatile interface for any situation.AC4490 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peer-to-Peerarchitecture. One transceiver is configured as a Server and there can be one or many Clients. Toestablish synchronization between transceivers, the Server emits a beacon. Upon detecting a beacon,a Client transceiver informs its Host and a RF link is established.This document contains information about the hardware and software interface between anAeroComm AC4490 transceiver and an OEM Host. Information includes the theory of operation,specifications, interface definition, configuration information and mechanical drawing.The OEM is responsible for ensuring the final product meets all FCC and/or appropriate regulatoryagency requirements listed herein before selling any product. 1 See AC4424/AC4490 Integration Guide for details

CTS OnCTS OnCTS OnCTS On in conjunction with CTS On HysteresisCTS On HysteresisCTS On HysteresisCTS On Hysteresis control the operation of CTS. CTS Onspecifies the amount of bytes that must be in the buffer for CTS to be disabled (High).

OnceCTS is disabled, it will remain disabled until the buffer is reduced to the size specified by CTS OnHysteresis.5.1.55.1.55.1.55.1.5 RTS Handshaking (pin 8)RTS Handshaking (pin 8)RTS Handshaking (pin 8)RTS Handshaking (pin 8)With RTS ModeRTS ModeRTS ModeRTS Mode disabled, the transceiver will send any received packet to the OEM Host as soon asthe packet is received.

This can causepackets sent at the same time by a Server and a Client to collide with each other over the RF. Toprevent this, Full Duplex Mode can be enabled. This mode restricts Clients to transmitting on oddnumbered frequency “bins” and the Server to transmitting on even frequency bins. Though the RFhardware is still technically half duplex, it makes the radio seem full duplex. This can cause overallthroughputs to be cut in half.

The AC4490 is a spread spectrum frequency hopping radio with a fixed hopping sequence.Without synchronizing the different networks to each other, different channel numbers could possiblyinterfere with each other and create “cross-talk.” To avoid cross-talk interference, co-located networksshould use Sync-to-ChannelSync-to-ChannelSync-to-ChannelSync-to-Channel. A Server radio with Sync-to-Channel enabled will synchronize itsfrequency hop timing to a system located on the RF Channel specified by Sync ChannelSync ChannelSync ChannelSync Channel. The onlyrequirement is that Sync Channel be numerically less than RF Channel. Therefore, every co-locatednetwork will be synchronizing to the network with the lowest RF Channel.
