Hi Everyone,

Thanks for all the info on this post. I've been able to gather a lot from here and the National Instruments site. Just want to make sure I have the info correct.

1.)The signal outputs of the sensors should go to the Digitial I/O, and no pullup is needed because the I/O card has built in pullups.

2.) It is safe to connect the signal to the Digital I/O, despite the higher voltage supply because the outputs are open collector.

3.) The Sensors can be powered by the 12V supply, but it may dip below the minimum 10.4 volts.

4.) Based on the ruling, one Solenoid breakout may connected to the 24V output, and a solenoid output can be used to power the sensors.

5.) Sensor supply lines may be spliced together (Or connected to a terminal block.) and connected to one 12V line, or one Solenoid output.)

It seems like the 24V option would be the better way to go, but I have one question. It seems to me that since the line trackers are only used for autonomous, what are the odds of the battery dipping below 10.4 volts during this 10 second period? Has anyone tested this and seen it fail with a fresh battery? Just wondering if the "Quick and dirty" method of using 12V, will suffice for practical purposes.

On a different note, does anyone know if the 24V ruling was done to accomodate the 24V solenoid that shipped in the KOP?
