USB Remote Interface

Use the instructions in the subsequent sections to wire and configure a USB Remote
Interface.

Wiring

The Calibrator comes with a standard USB cable. The USB cable has a 1394 connector
(Calibrator connection) on one end and a standard USB connector on the other (computer
connection).
To use the USB interface for remote operation, a driver needs to be installed on the
computer. After the driver is installed and the Calibrator is connected to the computer, the
USB connection appears as a virtual COM port in the PC communication software (for
example, MS Hyper-terminal). The driver is included on the CD that shipped with the
Calibrator. If the CD is lost, or a updated driver is necessary, go to
http://www.ftdichip.com/Drivers/VCP.thm.

Communication Setup

To use the USB remote interface, the Calibrator must be configured to communicate with
the computer. Configuration is done in the Communication Setup menu on the Calibrator.
