The device is intended for use by the
German Armed Forces and Government, as well
as by NATO sphere countries, and replaces existing fill devices like
and (partially) KYX-15.
When unkeyed, the DTD-II remains a Controlled Cryptographic Item (CCI).
The device has a 20 x 6 character liquid crystal display (LCD) and
a keyboard with 43 keys. It can handle variable length black and red keys, that are protected by means of a Crypto Ignition Key (CIK).
Up to 8 users are allowed per device, each of which is allowed an individual
CIK and keys.
The DTD-II is housed in a ruggedized die-cast aluminium enclosure and is suitable
for use under harsh conditions. It supports
three interface types: DS102 –
also known as Common Fill Device Interface (CFDI), used for legacy equipment –
and data header) and RS232D (for PC applications) all of which are wired via
the 6-pin U-229 (ODU) socket on the device [A].
