Using the UV-VIS Detector Sync Signals on the 920-LC/940-LC.

UV-VIS detector Ready, Start, and Fault inputs can be triggered, and UV-VIS detector Ready, Start

and fault outputs can be detected, using the signals from the Detector Sync connector at the rear of the

Varian 920-LC/940-LC instrument.

A circuit board with screw terminals to plug into the

Detector Sync connector is available (P/N 02-102285-00)

to be used with a customers own flying lead cable. This

board does not have any electronics on it, it just provides

a terminal block to screw wires into. Alternatively the

customer can assemble their own cable with the desired

terminations themselves.

These circuit diagrams show the electrical interface of

these signals inside the Varian instrument, to enable

anyone to use these signals.
