IEC 61406-1
One serial, one link.
Every unit we build carries a serial number. Its identification link, per IEC 61406-1, is that serial appended to this host, and it resolves to the unit's record here.
How a link is built

- Serial
- Printed on the nameplate as
SDN-EC1-26-00001-2: issuerSDN, model code, two-digit year, five-character sequence and a check character. The link uses the same serial without dashes. - Typing it in
- Dashes, spaces and letter case do not matter, and the usual misreads (I or L for 1, O for 0) are corrected. A serial whose check character does not verify is refused rather than guessed.
- Permanence
- A serial is issued once, never changed and never reused, even after the unit reaches the end of its life. The link stays valid for as long as the unit exists.
