Reading The Serial Number - EUCHNER EKS Manual

Manual EKS Electronic-Key Adapter Ethernet TCP/IP

8.3.3 Reading the serial number

The Electronic-Key read/write also has a unique 8-byte serial number that is permanently written to the memory
during the Electronic-Key production process. The serial number can therefore not be changed. This serial
number is used for secure distinction of every single Electronic-Key. It is necessary that all 8 bytes are
completely evaluated for secure distinction. The serial number is appended to the freely programmable memory.
The serial number can be read by entering the start address byte number 116 and the number of bytes 8 (see
chapter 8.3.2).

Information!
The current status of the EKS Electronic-Key can be polled actively at any time using the command
identification Ek. The EKS device responds also with command identification Ek and the information on
whether an Electronic-Key is in place or not.
This status message is sent automatically by the EKS also without request via the command message,
as soon as the Electronic-Key is put in place or removed.
