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.
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.
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.
