How do I know if my PE+ supports ID023 protocol?
Go into the menu by pressing the white test button. If you find a option that says "Country code: xx", it is most likely ID023. The reason you can assume this is that the older ID022 did not use country code.
So what if I don't find the option that say "country code: xx" on my PE+ ?
Your machine most likely does not support ID023 protocol. You can not use the interface board "out of the box". You would need to change software eproms on your machine to be able to use the interface board.
How do I know if my S+ supports ID023 protocol? (Methode 2 is prefered)
Methode 1) Go into the menu by pressing the white test button. Press a couple of times until you see Selection <0> [5], then use the reset switch to navigate forward in the sub menu. If you find the <0> [20], that is the option for country code and you most likely have support for ID023.
*NOTE 1: If option 17 (bill acceptor enable) is set to 0, option 20 will not show.
*NOTE 2: some SP chips, like SP1271, uses <0> [9] for Bill Acceptor Display. It looks like country code is displayed under <0> [30].
Methode 2) If you are a newlifegames member, you can download spreadsheet https://newlifegames.com/nlg/index.php?topic=33460.0. Look up your SP chip number in the list. If it supports bill validator protocol "ID023", "Version 2.4" or "Version 2.5" it is most likely ID023 support.
So what if I don't have ID023 support on my S+?
You can not use the interface board "out of the box". You would need to change software eprom on your machine to be able to use the interface board.
Do I need anything else to use set up the machine to work with the adapter?
You might need a SET chip to activate the bill acceptor, set the country code and set the denomination.
Not sure how to set up and use the adapter?
This video demonstrates setup and use.
