Hamilton credit card acceptor problem – Update

To get the Hamilton credit card acceptor out of the unit there are 4 bolts that hold it into the acw-5.  Unbolt them and the credit card acceptor comes right out.  Then remove 2 screws and the acceptor comes off the holder.  I then mounted the new acceptor and reversed the process, tested my credit card and everything worked great!  Now I can accept credit cards with my acw-5.

So after the download procedure I noticed that my credit card acceptor was not working.  It seems very easy to trouble shoot on the acw-5.  There are 2 plugs (second picture) on the back of the reader the second plug (red and black wire) should be 5 V DC.  While the top plug (yellow and brown) should be 5 or 8 V DC, of course it was ZERO V DC.  So I need to purchase a new credit card acceptor because Hamilton does not repair the acceptors anymore.  They cost $320 from Hamilton, but I called my buddy Randy Nix at Eagle Car Wash and he treated me right.

I called Hamilton support today (1-800-837-5561) and they dialed into my modem and checked out my credit card computer.  They said that the unit was turned off for a very long time and it was reset a lot of times.  So apparently they can not really check anything by dialing into the system.  (I knew that much!)  They did say to send the unit in to them and they think it will cost anywhere between $200 and $500 to fix.

William was trying to show me how the entry unit works and the Hamilton handheld would not work.  (The handheld, from what I have gathered, programs prices and the credit card computer.)  William called Hamilton to try and get the handheld to work but nothing would work.  Ends up that the cord was messed up (last picture).

I took the $1900 Hamilton credit card computer home with me to fix the handheld cord, which I did.  I did not take the 2 boards apart but the top board looks like an Aprotek modem.
