The AC4790 is a cost effective, high performance, frequency hopping spread spectrum transceiver designed for integration into OEM systems operating under FCC part regulations for the 900 MHz ISM band. AC4790 transceivers operate in a Masterless architecture. The unique feature of this architecture is its dynamic Session extension and Collision Avoidance mechanism, which uses a proprietary scoring system to promote contention free communication and ensure that each node has fair access to the network. This instinctive dynamic peer-to-peer networking architecture enables several transceiver pairs to carry on simultaneous conversations on the same network. To boost data integrity and security, the AC4790 uses AeroComm’s field-proven FHSS technology featuring optional Data-Encryption Standards DES . Fully transparent, these transceivers operate seamlessly in serial cable replacement applications. Communications include both system and configuration data via an asynchronous TTL or optional RS-485 serial interface for OEM Host communications. Configuration data is stored in an on-board EEPROM and most parameters can be changed on the fly. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver. This document contains information about the hardware and software interface between an AeroComm AC4790 transceiver and an OEM Host. Information includes the theory of operation, specifications, interface definition, configuration information and mechanical drawings. The OEM is responsible for ensuring the final product meets all appropriate regulatory agency requirements listed herein before selling any product. Note Unless mentioned specifically by name, the AC4790 modules will be referred to as the “radio” or “transceiver”. Individual naming is used to differentiate product specific features. The host PC/Microcontroller/Any device to which the AC4790 module is connected will be referred to as “OEM Host”.

Agency Compliancy Information Agency Compliancy Information AC4790-1X1 Due to the RF antenna trace residing on the OEM Host PCB, the FCC will not grant modular approval for the AC4490-1x1 and requires the OEM to submit their completed design for approval. Contact AeroComm for the approval procedure. AGENCY IDENTIFICATION NUMBERS Agency compliancy is a very important requirement for any product deployment. AeroComm has obtained modular approval for its products so the OEM only has to meet a few requirements to be eligible to use that approval.
