DS1204V Description
The DS1204V Electronic Key is a miniature security system that stores 64 bits of user-definable identification code and a 64-bit security match code that protects 128 bits of read/write nonvolatile memory. The 64-bit identification code and the security match code are programmed into the key via a special program mode operation. After programming, the key follows a procedure with a serial format to retrieve or...
