AC4790 - 200A

http://www.lairdtech.com/products/ac4790

The high-performance AC4790 radio modules utilize Laird's masterless protocol, allowing each radio module to communicate with any other in-range radio module for true peer-to-peer operation. Using field-proven 900MHz FHSS technology that needs no additional site licensing*, AC4790s reject interference, enable co-located system operation, and ensure data integrity. The AC4790's protocol features a dynamic addressing scheme, that simplifies node-to-node communication. The radio module enables identification of the most efficient transmission path, so OEMs can design routing sequences that optimize the RF network. This makes the AC4790 ideal for a wide variety of industrial applications that must rely on smooth, constant data flow. Developer tools and comprehensive technical support are available to aid integration. Let Laird help you find the best fit for your application.

Features

FLEXIBLE RF PROTOCOL

Laird Technologies’ RF232™ embedded transparent protocol simplifies the OEM’s integration process by providing drop-in installation. As each radio module receives raw data, it manages the over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not required. The AC4790’s flexible “masterless” topology supports simple cable-replacement up to complex peer-to-peer configuration. It allows you to broadcast to all radio modules or address packets to a specific destination using unique MAC addresses embedded in each radio module.

RF Protocol Modes

Communication: Unicast (one-to-one addressing), Broadcast (one-to-multiple addressing)

Acknowledgement mode (ACK): API with hardware and/or software, ACK indication
