USB Support on MS-2000 WK Controllers

Identification of WK Controllers

There are several way to identify a WK Controller:

  • Refer to the label on the bottom of the controller. The Model number will begin with “WK”, not “MS”.
  • With Dip-Switch 2 in the DOWN position, the last line of the LCD should display the firmware version. “WK” controllers will be version 8.0 or higher.
  • When queried with the Version command, “v”, from a terminal program, the firmware version response will be version 8.0 or higher.

Instructions for Installing USB Support for WK Controllers

ASI currently employs Silicon Laboratories’® CP210x USB-to-UART Bridge Virtual COM Port (VCP) in its WK-series controllers for emulated COM Port (RS-232) communication over USB connectivity.

To enable your computer’s USB ports to successfully communicate with ASI’s WK-series controllers, you need to download and install Silicon Labs® VCP Driver.
