1. If you do not use vs2010 as a development tool, it doesn't matter, only need
1.1 will EPCSDK. DLL in running the program directory
1.2 will EPCSDKHelper. Cs copied to the source packages.

2. Use as follows
/ / define a current handle, in addition to the OpenComm all called method will need the handle.
IntPtr p = IntPtr. Zero;
try
{
Int portNum = 1; / / serial number
P = EPCSDKHelper. OpenComm (portNum);
}
Catch (Exception ex)
{
MessageBox. Show (ex. The Message);
}
/ / definition need to accept the parameters,
Int main = 0;
Int sub = 0;
/ / out to show this parameter for output parameters
Bool b = EPCSDKHelper. ReadFirmwareVersion (p, out main, out sub);

Int paramNum = 4;
Byte [] bo = new byte [paramNum];
/ / vc byte * type corresponding c # type for byte [], need to be in calling methods before, first instance parameters. If byte not to confirm the word length, length set big points.
EPCSDKHelper. GetReaderParameters (p, 0, 4, bo);

/ / other function is similar
When using please note:
A. test this DEMO, the first to "connect the reading and writing".
B. "began to read sheet card", make sure card reader set to output a serial port, if is connected to ensure that the 485 set to 485 output. At the same time card reader to DEMO software Settings to use single card mode.
C. "began to read more CARDS, be sure the card reader" set to a serial port, if is linked to the 485 output is to ensure that set to the 485 output, at the same time, with a card reader software set to DEMO multiple CARDS mode.
D. to label operation (read or write tag), the first to "basic operation" down "stop to read the label".
E. "quick write card", only can write EPC area, the input is four, eight, and twelve, 16, 20 a, or 24 a hexadecimal number, that is the most 12 bytes. Write card be wrote the card last.
F. "write card" is can write EPC area, can also write other area (such as reservations, the user area), but only can write a word, namely two bytes.
G. "to read the label" can read EPC area, also can be other area (such as TID area, reservations, the user area), the length and the address can be specified.
EPC area the longest six words (12 bytes), EPC data from address 2 begin.
TID area the longest 4 words (8 bytes), TID data from address 2 begin.
Reserves, the longest 4 words (8 bytes), address 0, 1 is destroyed MiMaOu, address 2, 3 is to visit MiMaOu.
Once a user area most read 8 words (16 bytes), address from 0.
H. "read the card" read-only EPC area address 2-7 six words (12 bytes), this command reading card distance than "to read the label" far.
I. password default is 00000000, password is 8 0 words, EPC area is can't lock, even if the lock can rewrite
When the password for the 0, the EPC area if lock cannot be rewritten, if want to rewrite must first to unlock, can write data once again.
