National Vendors Snacktron 1, using a Mars TRC-6000 coin mech and a Mars VN2511 bill validator. The validator flashes a code that it is disabled from the mech/VMC and I can't find out why. During power-up the validator goes through its initialization but immediately starts flashing the two flashes of the LED. The arrows on the outside of the bezel are not lit and it will not accept bills.
I have tried restarting the whole machine, unplugging and replugging the components, moving the dip switches in the coin mech. Nothing makes any difference. The coin mech works fine, it vends and makes change. The coin tubes are full and function normally.
What do I try next?

I have a REfreshtron with the same setup that flashes disabled because the door is open.Find the white door switch and hold it in to see if it stops flashing(mine does. This may seem like a dumb question but,is there enough nickles in it?Does your machine say coins only on the display,if not then the problem is in the validator.National Vendors Snacktron 1, using a Mars TRC-6000 coin mech and a Mars VN2511 bill validator.

I've tried the door switch. It makes no difference. The coin tubes are full. The display says "coins only" and the machine passes all other diagnostic tests. I've had it in operation this weekend and it works fine with coins. It vends, makes change, and does all it's supposed to do. It just won't take a bill. Won't even try.
There's a coupon setup button on the validator and if I have all the mech dip switches set to off and hit that button, it will go into coupon setup mode. During that mode it will take a bill, hold it for a second, then spit it back out and go back to the error code.

There are a few things that can cause the problem. 1.there is a credit already established 2.coin tubes must have at least 10 coins in them. 3.coin tube sensors malfunctioning (rare but can happen). 4.check "machine Configuration" make sure its set for the right validator and it is set to accept the right denomination. 5.this is probably the most important depending on what harness and interface your using since it is mars mars there should be two flat black connectors in the side of the validator 1 small and 1 larger there is probably a bent pin where the big one plugs in. Its hard to see and you will probably have to pull validator out to see it. Just a thought.Replying to both: It's a 145. The number on the plate inside the door is 145 54143. I bought this machine used from a man who had several machines on a 5 county route. It was supposedly in good working condition but he was upgrading all his machines and selling off the old ones. He plugged it in and tried most functions - price change, diagnostics, etc. He had the door open during all this and neither of us thought to check the validator. I have been unable to reach him by phone since that time but I'll keep trying. He mentioned when I picked it up that it would not vend without coins in the tubes so we robbed the soda machine to fill the tubes when we got it home.

I checked the flat connector on the side, there were no bent pins. It was all in the dips. I set it to accept bills in 2-way, turned ON the $1 permission (!) and set the security level. I had to trip the door switch, which was suggested above. Once I did that, the flashing LED turned solid. I closed the door and fed it a bill. It clicked, whirred, took my bill, - and just sat there. No credit. No "Thank You", not even a good night kiss.
After pulling the validator 3 more times I noticed dip #8, "credit". I turned that one on and everything started working. It now accepts $1 bills, issues credit, makes change, everything it's supposed to do. Like an old, fat, grizzled prince kissing Sleeping Beauty out of a deep sleep, we're back in business.
Thanks to all who replied, I would never have gotten the nerve to pull the validator out without your encouragement. I have the manual downloaded which gave me all the dip settings but this is uncharted territory for me. I can adjust the valves and rebuild the carburetors on a 1100cc Honda V-4 motorcycle engine in the dark but with this thing I feel like Jethro Bodine doing brain surgery.
Thanks again for all the advice. Next week I'm going to try to tickle this ancient Dixie Narco can machine to do bottled water, I'm sure I'll be back.
