Allen-Bradley 1747-UIC USB to RS-485 Converter

The Allen-Bradley 1747-UIC USB-to-DH-485 interface converter is a dedicated USB-to-RS-485 bridge that enables a PC to communicate with DH-485 devices on an RS-485 network, notably SLC 501/502/503 CPUs and other DH-485-equipped components. The unit provides a USB connection on the PC side and a DH-485-compatible RS-232 interface on the device side, allowing token-passing communication between a Windows PC and Allen-Bradley hardware used in SLC 500/MicroLogix environments; it serves as a modern replacement for older serial programming cables. Setup requires Rockwell Automation drivers, typically via RSLinx Classic, after which the 1747-UIC is recognized by the PC (Found New Hardware will show Allen-Bradley 1747-UIC during installation). Catalog Number 1747-UIC is documented for use with RSLogix 500, RSNetWorx for DH-485, and PanelBuilder32 in DH-485 projects, providing a straightforward path to programming and configuration of DH-485 networks from a PC. The product is specifically described as a USB-to-DH-485 interface converter, bridging USB with the DH-485 network to support Allen-Bradley SLC and MicroLogix communications via the RS-485 protocol.
