2. To ensure proper ground, make cable connections between the 1747-UIC and the DH-485 device or interface first. See Making Cable Connections on pages 5 through 7.

3. Plug the 1747-UIC USB cable into the computer’s USB port. The green OK LED should turn on to indicate that the 1747-UIC is receiving power through the USB port.

4. If this is the first time that this 1747-UIC has been connected to this computer, you must install the 1747-UIC drivers. See Installing Drivers on page 7.

5. Identify which COM port has been assigned to the 1747-UIC. See Identifying the Assigned COM Port on page 11.

6. Create an RS-232 DF1 Driver within RSLinx. See Configuring the 1747-UIC in RSLinx on page 12.

7. Verify DH-485 communications using RSWho. Both the USB and DH-485 green LEDs should be flashing when communications are working.
