ECOLEX 10
Manufactured by Phillips Usfa, it was used by by the Dutch Ministry of Foreign Affairs and the Dutch military.

The machine had a number of thumbwheels to set the daily key. On top of that a noise generator was used to add extra random key which was transmitted to the far end. When not actually encrypting data, the unit kept transmitting over the link.
