I picked up a few Craigslist specials for IGT s+ games. I am looking to replace DBV on both. How do i know what validators to use?
i already have 2 working machine that use differnt DBV's one is a dbv-200 the other is dbv-145.
The main difference between a DBV-145 and a DBV-200 is the -145 only accepts a bill 1 particular way. The bill has to be inserted face up and with the top of the portrait head to the left. (I think that's correct).
The -200 has what is called 4-way acceptance, meaning you can insert a bill any way you want, face up, face down, portrait facing left or right. Another difference is that since the -200 is the newer model it had software updates later in time. Neither is getting updates anymore but in some instances a -200 will accept a few more bills still in use than the -145 will.
These bill validators are made by a company called JCM, but they are used in a variety of machines made by different companies. Each company has a different communication method for the machine's mpu (processor) board to "talk" to the bill validator. So inside the bill validator is software loaded into a chip that customizes the bill validator for that particular machine. This communication method is called the ID protocol, it has a number such as ID-023 or ID-003. For the IGT S+ machines ID-023 is used. If you look at your DBV heads that work in your S+ slot you may see a sticker with the marking "ID-023" or something similar.
Usually, but not always, there is a label or sticker on the DBV saying what ID protocol it is programmed with. But over time sometimes someone will reprogram the software to a different ID protocol for another machine and not change the label. On the DBV-200 you can turn it upside down and view the eprom or flash rom, sometimes there is a label on it. For the DBV-145 you have to take off part of the housing to view the rom inside.
The DBV-200 is a direct replacement for the DBV-145, as long as you get one that has the same ID protocol (ID-023 in this case). You can remove the DBV "head" of the bill validator unit, leaving the transport and other housing components and install another "head" easily. If you find a good working DBV-200 that you want to use but it is the wrong ID protocol the -023 software can often be loaded into it. The last DBV-200 heads were made with either an eprom or a flash rom to hold the software. Those with an eprom can have software updates done by anyone with an eprom burner. Those with flash rom require a more elaborate setup using a special cable and programming software from JCM.
