Configuration jumpers?

[john@thedevils-den]

Can someone explain to me how to disable the p6 and p7 configuration jumpers as per the training .pdf for the Prop1 trainer?
What are they wanting me to do? I have everything sitting in front of me, just need some guidance. Thanks.

Sure, just pull them out and store them on one pin (I usually use the UP side).

Jon,

Not to sound silly, but when you say"just pull them out"......what is the them? I got my order today, by the way. Thanks for the fast shipping. Anyways, Im not sure what Im looking for on the P6 and P7 input configuration UP or DN. What is the jumper? Thanks for your help and I apologize for the very Noobie questions. I am very interested in learning the programming for these and with your help I think I can learn it.......

"Them" is the SETUP jumpers (some people call them shunts or shorting blocks).  If you look just above the reset button you'll see two horizontal 3-pin headers labeled "SETUP"; one side is labeled "UP", the other "DN".  These jumper are used to connect two pins together, in this case the middle pin connects to the I/O point, the outer pins connect to pull-up or pull-down resistors.  See page 4 in the docs for a description.

 Is there a jumper wire that connects to the 3 pin header? In the diagram, it shows a grayish circle around the correct orientation for the jumper. I am used to seeing a jumper"wire" or a plug that "jumps" two pins together..........I guess what I am asking is what actually connects the pin to either the pull up or down resistor? Do i need to make a wire with  2 pin connector, or does the prop1 come with some sort of jumper? Thanks again and sorry for the confusion.

 Ok I got it...the "Block" is removable and is used to connect the center pin to high or low........sorry

I'm still a bit confused on jumper use and the terms active-high and active low. 

When the jumper is placed in the "UP" position, the pin is pulled up
to Vdd (+5v) through a 4.7 kresistor – this is the setting to use for active-low trigger devices or configurations
(i.e., a normally open switch placed between the trigger pin and ground).

When the jumper is placed in the "DN" position, the pin is pulled down to Vss (ground) through a 4.7 kresistor; this is the setting to use for active-high trigger devices or configurations
(e.g., the output from a PIR sensor).[/i]

I am currently using a PIR along with a test button that connects the red and white.  In looking at the documentation the picture of the NO switch does not seem to correspond with the jumper indicated in the text (above).  I guess my question is what position should the jumper be when using a PIR and what position should it be when using a NO switch (manual trigger).   Thank you for your help.

If you are using a PIR the jumper should be in the DN position as stated in the docs. When you say N.O. switch you have to define what it is connected to. If you have a N.O. switch connected to RED and WHITE then it has the same result as the PIR , Active High, which means 5v positive is being supplied to WHITE when the switch is closed. For Active Low, a N.O. switch would be connected between BLACK and WHITE with the setup jumper in the UP position and no ULN. This configuration provides ground to the WHITE when the switch is closed.
