5.1.2 USBTMC
The instrument supports USBTMC (Test & Measurement Class) interface. Use a USB Type A to Type B cable to
connect the USB device port in the rear panel to the computer. A driver is required before it can be used for
remote communication. A computer with VISA-such as NI-VISA-installed will automatically have the driver
available, and upon connecting the USB to the device, drivers will automatically install on Windows®7 or later.
5.1.3 USBVCP
USBVCP is a USB Virtual COM interface option. A driver is required (downloaded from www.bkprecision.com) to
be installed before it can be used. The setup is similar to an RS232 interface, except that a USB Type A to Type B
cable is required for remote connection instead of a DE-9 serial cable.
5.2 Handler Interface
The instrument has a 36-pin handler interface, which is primarily used for outpuing BIN sorting results. This
section describes the pin definition of this interface.
Mating connector: 36 pin Centronics type, male.
