Frequently Asked Questions

What is Allen-Bradley 1747-UIC?
Allen-Bradley 1747-UIC is a USB to DH-485 interface converter designed to connect a computer to compatible SLC 500, MicroLogix and PanelView equipment communicating over DH-485.

What communication ports are available on the 1747-UIC?
The converter includes a computer USB interface and selectable RS-232 (DH-485) and RS-485 (DH-485) equipment interfaces. The selector switch must match the connected port.

What is the DH-485 communication speed?
The 1747-UIC operates at 19.2 Kbps on the DH-485 network. It does not support automatic DH-485 baud-rate selection.

What USB version does 1747-UIC support?
The manufacturer specifies USB 1.1 with a USB data transfer speed of 12 Mbps and power consumption below 100 mA.

Does 1747-UIC require an external power supply?
No. The interface converter receives operating power directly from the connected computer USB port.

Which SLC 500 controllers are compatible with 1747-UIC?
The RS-485 interface supports SLC 500 fixed controllers, SLC 5/01, SLC 5/02 and SLC 5/03 Channel 1. The RS-232 interface supports SLC 5/03, SLC 5/04 and SLC 5/05 Channel 0 when configured for DH-485 rather than DF1.

Which programming cables are used with 1747-UIC?
The manufacturer specifies 1747-C13 for supported RS-485 connections and 1747-CP3 or 1756-CP3 for supported RS-232 connections. Other equipment may require different cables, and programming cables must be selected for the specific device.

How is 1747-UIC configured in RSLinx?
Install the appropriate USB drivers, identify the assigned COM port and configure an RS-232 DF1 Devices driver. Select 1770-KF3/1747-KE, CRC error checking, 19200 baud and an unused DH-485 station address. Do not use AutoConfigure.

What do the three LED indicators mean?
A solid OK LED indicates USB power and operating status. A flashing USB LED indicates USB-side data activity, while a flashing DH-485 LED indicates DH-485 network communication.

Does 1747-UIC support Windows 10 or Windows 11?
The published installation manual documents Windows 98, Windows 2000 and Windows XP with RSLinx version 2.41 or higher. Modern Windows compatibility must be verified using available drivers and the specific RSLinx configuration; support on Windows 10 or Windows 11 should not be assumed.

What are the dimensions and operating temperature?
The converter measures approximately 80.8 × 46.5 × 24.5 mm without DIN rail hardware or 109 × 50.6 × 31 mm with the specified mounting hardware. Its operating temperature range is 0°C to 60°C.

Has Allen-Bradley 1747-UIC been discontinued?
Yes. Rockwell Automation lists September 30, 2024 as the discontinuation date and indicates that no manufacturer replacement is planned. Before ordering, verify the exact catalog number, host controller and DH-485 port configuration, required cables, software drivers, computer operating system and installation requirements.
