Found it. It's a small plug that was included in the P3 upgrade kit.
Hi,
I have a 50ohm BNC terminator plug. Can i use this as the NULL Plug.
If you wanna have accurate results: No. The original plug is short circuited - see also http://www.aquariumcomputer.com/Foru...l-plug&p=16243I have a 50ohm BNC terminator plug. Can i use this as the NULL Plug.
Thanks Wirus,
As a test, I made a null connector as described in the post. It looks like the 50ohm terminator creates enough of a short.
My adc1 was the same (427) with both the shorted connector and the terminator.
