According to the Universal Wiring Diagram I posted to help with this question, you would need to put the jumper in the 2-3 position (Or as the above illustration shows, position 'B').
The I/O board in the diagram is the rev. A (838-13683-91), where the jumper has a different location and is marked IN/OUT. The pic I posted is of a rev. B (838-13683-93). I would imagine that if his I/O didn't match the pic I posted he wouldn't have said that the jumper was OK.

Friend sorry!!! Quest resolved!
I cont the pins on inverse order... on remove the board from gabinet I see this connector start on pin 14 and coming on decrescent order! On count again pin 4 and pin 8 working very well. I use GND from Jamma and this board is REV. B, jumper on positon 1-2 (A) working ok! I so gratefull for help of MKL and Joshua3dg! Great helpers! Thanks Again.
There are more 'B' versions since the 'A' version was discontinued early, so I tend not to mention it unless it's necessary. To make things simple, the jumper needs to be set to the 'IN' position.

Measure the resistence to ground of the faulty one and compare it to that of the other inputs on the same connector. It could be a bad P181 transistor. In that case you could replace it with one from the unused input lines.
This information is very important for fix a input with hardware problem! Thanks MKL!
