we are using a Keithley 2450 and we want to recorded the light output of OLEDs as the voltage increase.Therefore we connect the Keithley instrument to a digital Photometer L203 from IRRADIAN through the digital I/O port.
We would like to make sure that the photometer is recognised by the instrument and to know if it is possible to see it on KickStart ?
Thanks for any answer you can give us.
The kickstart software does not support third-party instruments.

I suspect the motivation for the connection between the photometer and the 2450 is for triggering or coordination of when each makes a reading.
You'll have to determine if the photometer has any sort of digital triggering feature. If yes, then it could be possible to interface that trigger input of the photometer to the trigger output of the 2450.
However, the DB9 on the photometer is an RS-232 communication port. You would connect this to a COM port on a computer.
Alternately, if photometer does not have any triggering feature, then from a custom software routine you can tell 2450 to source a voltage, measure the current and then over RS-232, tell the photometer to give you a reading. Then repeat at the next voltage if trying to generate an IV curve.
