Also, the antennas should be vertical, not horizontal. 3-You only used 2 of the 4 screws to secure the swipe unit. It's all MDB. I tried the antennas further apart, vertical, and outside of the machine. No change. Still "cards offline by vendor". Link to comment Share on other sites More sharing options...
AZVendor Posted October 3, 2019 Share Posted October 3, 2019 Then it's an eprom issue or your card reader is bad. Link to comment Share on other sites More sharing options...
DAG Posted February 7, 2020 Share Posted February 7, 2020 Hi all, Just reading this post so a bit late to the show. How do you confirm that DEX works on a machine before committing to adding card readers, etc.? Link to comment Share on other sites More sharing options...

I don't know of any way to "test" a machine other than doing the install, but the list will let you know which machines should work.... Link to comment Share on other sites More sharing options...
DAG Posted February 7, 2020 Share Posted February 7, 2020 Southeast Treats (and anyone else on this thread), Thanks for the reply. This makes me wonder - would it be of value to have an App on the Apple App store for your iPhone or iPad that could perform a DEX and parse and display that information? I have written an App that does that using a few different manufacturers bluetooth adapters as well as a plug-in lighting port cable. I was thinking maybe a basic free version that just tests if DEX works and maybe a pay version that does more analysis of the data. Trying to understand if it is worth my effort to get this thing into the App store. I wrote it and currently use it as part of my consulting business for a few large bottlers to help with their vending businesses. It also has features that help speed-up the set-up of vending machines by setting prices, space-to-sales, etc. Any feedback would be much appreciated.

Apple Leisure Posted February 7, 2020 Author Share Posted February 7, 2020 I probably should have announced this earlier, but since DAG reminded me (thanks) I did replace the eprom and the cc reader works perfectly fine now. Nothing else was changed, i.e. antenna location etc. I hope that helps someone. Link to comment Share on other sites More sharing options...
DAG Posted February 7, 2020 Share Posted February 7, 2020 That is usually the culprit. We first check if the machine will DEX. If it can DEX, the eeprom version is usually stored in the DEX data. We have a look-up that checks the eeprom version for each manufacturer and check if it is up-to-date to support the features we need. If not, we update the eeprom to the latest.

For someone like me it could be used as a test tool, and it wouldn't need to be parsed. I would pay .99 for a tool like that if I was DEXing, but I currently have a test solution with my VMS. I've been reading raw DEX for many years now. Link to comment Share on other sites More sharing options...

DAG Posted February 7, 2020 Share Posted February 7, 2020 Thanks for the feedback. Yes - it is useful as a diagnostics tool when the telemetry won't DEX. Can trace or test bad wiring and old eeproms. Link to comment Share on other sites More sharing options...
Corvus Corax Posted February 10, 2020 Share Posted February 10, 2020 I put on some 4 in 1 units and had a bad 5v power supply on one. It would intermittently shut off the reader. I would definately start with an up to date eprom first, before you drop real money into it. Link to comment Share on other sites More sharing options...
