Tech Tip: Using a Mars VN validator in an amusement machine

Recommended Posts

Posted (edited)

With this downturn and stay at home order I have a golpher ton of time on my hands. 

As I have been cutting down my fleet of single price sodas and upgrading my snacks with UCBs I have found myself with a golpher ton of surplus Mars VN 2501s and 2511s. Many are in nice shape and are new 5 ready, so I wanted to see if I can use them in my cranes instead of buying AEs. Normally, the VN needs a coin mech to enable it to work. The AE can be enabled without anything plugged into it using a switch, which is why it is ideal for amusements.

I found the manual, here: https://www.vend-resource.com/sites/default/files/mei_vn_series_2000_operational_service_guide.pdf

It references enable jumper cable, Mars P/N 250074011. This allows the validator to remain always enabled, like an AE.

A quick search reveals this: https://www.dsvendinginc.com/p-2360-d250074011-marsmei-harness-vn-series-125-enable-jumper.aspx

And this: https://www.capitalvending.com/mei-enable-board.html

However, the same shutdown that has blessed me with a bunch of time has also taken my money. And DS is closed.

So, I set off to make my own. Turns out shorting pins 10, 27, 28, 29 together, and then 25, 13, 14, 15 together (2 different sets of shorted wires) is what the jumper harness does. Disclaimer, do it at your own risk. I am not liable for any errors or omissions, nor your own incompetence.

Then, you just plug in a regular Mars power/credit harness. https://na.suzohapp.com/products/bill_validators/42-7057-00

For the full line guys out there this is also a good way to test a 110V validator without needing a machine.
