I used to use an ADC42 single channel one earlier on the parallel port on my computer (XP OS).
I recently purchased a ADC-100 dual channel logger, and connected it
to the parallel port to which the ADC-42 was earlier connected (after removing the 42). I am using an XP op. sys. I reinstalled all the software, selected the module as ADC-100, and also the port as LPT1.
But for some reason, I do not see any signal on the oscilloscope.
I am testing with a sinusoidal wave generator as signal input.
If i reconnect my ADC-42, i can see the wave on the oscilloscope.
But the ADC-100 for some reason is giving a flat line on both the channels.
Do i have a defective ADC-100 module, or is there a mistake in the way i am operating it.
