Ich habe ein Problem mit der Umsetzung des mittgelieferten Code nach Delphi?[/B]
Wer kann etwas damit anfangen?
"leider keine
DLL"
Danke für jeden Tipp..
The K8019 communicates in bytes, not with text, don’t use telnet
A packet looks like this:
<42> = always 42 hex
<??> = size (in bytes) of the en�� re packet
<??> = command byte
<ff > = always ff hex
<??>...<??> = op�� onal extra data
NOTE: <42> is the hexadecimal number 42, contained in 1 byte
Card swipe event
receive: card swiped
<42><09><07><ff ><??><??><??><??><??> (= tag of 5 bytes)
Reading all cards
send: read database
<42><04><02><ff >
receive: transfer started
<42><05><03><ff ><??>(= index of master card)
receive: card
<42><04><04><ff ><??><??><??><??><??> (= tag of 5 bytes)
receive: transfer complete
<42><04><05><ff >
Adding a single card
send: add card
<42><09><07><ff ><??><??><??><??><??> (= tag of 5 bytes)
Clearing the database and adding mul�� ple cards
send: start database update
<42><05><06><ff ><??>(=index of master card)
send: card (repeat for each card)
<42><09><07><ff ><??><??><??><??><??> (= tag of 5 bytes)
receive: card added (for each card)
<42><04><08><ff >
send: end database update
<42><04><09><ff >
