Hello,
Ik have a wireless-payment-system in my pinball connected through NRI. On the photo the ten pins in the black cover( left from the red rectangle).
The NRI for Atack From Mats is stated at https://www.ipdb.org/files/3781/Bally_1995_Attack_from_Mars_Operations_Manual_FINAL_dated_January_1996_OCR_searchable.pdf
page 3-32, in the right upper corner. 2 wires for the current and 1 for the pulse of a specific coin door slot. When the euro/dollar is accepted a single pulse is sent. Sometimes the pinball is not picking up the pulse and the credit is not registered.
My question is: How long (duration), how much voltage and current needs the pulse to be?
Thanks for reading and possibly answering!
