PREREQUISITES
•
A computer with a USB port
•
A USB Link (Part #USB-L)
•
For the Field Assistant application to communicate with the controller, the controller must have been

CAUTIONS
•
Maintain polarity when controllers share power.
•
Failure to maintain polarity while using the USB Link on a computer that is grounded via its AC adapter may
damage the USB Link and the controller.
•
If multiple controllers share power but polarity was not maintained when they were wired, the difference
between the controller's ground and the computer's AC power ground could damage the USB Link and the
controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link. Purchase a USB isolator online from a third-party manufacturer. Plug the isolator into your computer's
USB port, and then plug the USB Link cable into the isolator.
The USB Link driver is installed with a v6.5 or later system. Please refer to the Silicon Labs website and
1
search "CP210x USB to UART Bridge VCP Drivers" for the most current device drivers. Install the driver before
you connect the USB Link to your computer.
