Powering Coin Mechs

Pages: (1/3) > >>

urbecrisch:

My project is converting a CAB to Mame.  There are 4 working coin mechs in my CAB and I'm wondering what I should do to power them up and connect them to my encoder.

1. When powering 4 coin mechs, can I use my 5v PC power supply split into 4 ways or use my CAB power supply?  Will each get equal power if the wires are split?

2. I'm assuming all I need to do to get the coin mechs to work is connect each coin slot (1&3 will be 1 player, 2&4 will be two player) to the encoder?

My coin mechs were plugged into the Jamma harness and powered through the CAB.  I just want to make sure I can disconnect the old wires on the coin mechs and use new wire running to the encoder and powered by the CPU 5v.

Here in the USA coin acceptors are mechanical devices. They mechanically check the physical properties of a coin then send a valid coin out the "accept" hole to trip a coin microswitch.

The only "power" going to the coin door shoud be for the coin entry lamps that light up the reject buttons and if your door is so fitted, for coin "lockout" coils.

urbecrisch:

You're right.  I wasn't specific enough.  If I want to "power" the lamps, is it OK to split the 5v coming from the PC power supply?  I know the coin mechs work, it's just a question of powering the lamps.
Cheers!

Ken Layton:

Coin door lamp powering has already been quite well-discussed on these forums.
