1. USB Interface Connection

Users can remotely control the power supply via PC over the USB interface. Upon installation of
the USB driver, the PC can control the instrument over virtual COM.

Connecting Instrument to PC

a) Download the USB drivers from www.bkprecision.com .
b) Connect the included USB cable to the power supply and the USB port on the PC.
c) When Windows recognizes the USB connection, do not follow the default Windows driver

installation wizard. Simply run the setup file from the downloaded USB drivers and follow
the prompt to install drivers.

d) The computer will recognize the instrument as a USB (virtual COM) device, it will be

detected as a serial COM port. Windows will automatically assign a COM port to the
instrument. Please verify which COM port Windows has assigned by going into Device
Manager.
