I thought buying this unit was going to be easy to set the password for waiters to access them menus. All i need is to get an example to write 4 digit passwords eg: 1133. thats it. That is what the waiters/manager need to do swipe their cards and they get into the software.
Can we get some information on what it is you bought?
Hey,
I am still having the bizarre task of trying to just get this card reader/writer to actually write anything.
Do you mind giving me the program/code to how you’re even writing anything on cards?
If I use the sparkfun program, I can read cards. After that, I can not get hyperterminal or any program to write to a single card. I just want the basics - read, erase, write.
Thanks
Jules
I’ve gotten this to work, both reading and writing. But so far, only with the Example software, and only on COM1. Also the read/writer gets its 5V power from the ps2 connector. Without the ps2 connector connected, the device will not work.
