Universal Serial Bus (USB) to DH-485 Interface Converter 3
Overview
The 1747-UIC allows you to connect devices that communicate using DH-485 protocol directly to a computer’s USB port, using either the 1747-UIC’s RS-232 or RS-485 port and user-provided programming cables. Three LED indicators on the 1747-UIC provide communication status.
Computer and Operating System Requirements
The USB to DH-485 interface converter works with RSLinx version 2.41 or higher and Windows98/2000/XP, on computers equipped with USB ports.
Install the Interface Converter
To install the interface converter:
1.Determine whether you will mount the interface converter. The interface converter can be mounted on a DIN rail using the DIN rail mounting kit (included).
2.Install the Ferrite Collar for EMC Compliance. See page 4.
3.Slide the switch (SW) on the interface converter to indicate the appropriate port.

4.To ensure proper ground, make cable connections between the interface converter and the DH-485 device or interface first.
See Connect DH-485 Devices to the Interface Converter’s RS-485 Port on page 5 or Connect DH-485 Devices to the Interface Converter’s RS-232 Port on page 6.

5.Plug the 1747-UIC USB cable into the computer’s USB port. The green OK LED indicator should turn on to indicate that the 1747-UIC is receiving power through the USB port.
6.If this is the first time that this interface converter has been connected to this computer, you must install the 1747-UIC drivers.
See Install the Drivers on page 7.
7.Identify which COM port has been assigned to the interface converter. See Identify the Assigned COM Port on page 11.
8.Create an RS-232 DF1 Driver within RSLinx.
See Configure the 1747-UIC Interface Converter in RSLinx on page 11.
9.Verify DH-485 communications using RSWho. Both the USB and DH-485 green LED indicators should be flashing when communications are working.
IMPORTANT |
Always stop the RSLinx RS-232 DF1 driver or shut down RSLinx |
|
prior to unplugging the interface converter from the computer’s |
||
|
||
|
USB port. |

Install the Ferrite Collar (European EMC Compliance)
Install the provided ferrite collar on the 1747-UIC cable for suppression of electromagnetic emissions and interference. The collar is required for compliance with the European EMC directive.
To be most effective, the ferrite collar must be placed between the cable ties on the USB cable where the cable exits the 1747-UIC interface converter.
1.Fold the collar so that it encircles the cable.
2.Press the plastic housing until the collar snaps together.
3.Check that the collar is fully latched.
