Introducing: the AC4490 transceiver from The AeroComm AC4490-200 from TeleLink Communications is a cost-effective, high performance, frequency hopping 900MHz spread spectrum transceiver with 200mW output. And now there’s a high power version, the AC4490-1000, offering a very long range 1000mW output. They can be used as a direct serial cable replacement – requiring no special host software for operation. They also feature a number of on-the-fly control commands providing the OEM with a very versatile interface for any network. They provide an asynchronous TTL/RS-485 level serial interface for OEM host communications. Communications include both system and configuration data. The host supplies system data for transmission to other host(s). Configuration data is stored in an on-board EEPROM. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver. RF-232 supports point-to-point or point-to-multipoint, client/server or peer-to-peer configurations. One transceiver is configured as a server and there can be one or many clients. To establish synchronization between transceivers, the server emits a beacon. Upon detecting a beacon, a client transceiver informs its host and a RF link is established. AeroComm’s embedded transparent protocol simplifies the OEM’s integration process by allowing for drop-in installation. As each transceiver receives raw data, it manages over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not needed. Broadcast communication to all transceivers or address packets to a specific destination using unique MAC addresses embedded in each transceiver. N also avaow ilable in 1000mW version!
