Remote Control
of the PR-680/680L is accomplished using commands sent from the PC in ASCII (text)
strings to the instrument. These commands are then executed and the requested information including
measured values or instrument setup parameters are returned to the PC.
The PR-680/680L is controlled from a personal computer over the Universal Serial Bus (USB) interface.
This is achieved by using a driver that parses appropriate ASCII (text) commands from the PC application
then transmits them over the USB I/F to the PR-680/680L.
Communication protocol is identical to RS-232 communications. The USB driver emulates an
RS-232 interface including opening a COM: port, setting a baud rate, parity, stop bits and flow control.
This makes Remote Control operations available for application software written in Microsoft Visual
Basic, Microsoft C++ or any other language that is capable of opening a COM: port.
Note:
While the PR-680/680L is in Remote Mode, the instruments touch screen is disabled.
