1-10. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
The ANCD is a hand-held device capable of receiving, storing, and transferring data between compatible equipments. The
primary application shall be the transfer of variable length electronic keying material, frequency hopping data, and other
Communication Security (COMSEC) related variables. The ANCD is sufficiently programmable to replace and preclude
the development of equipments tailored to a unique system. The programmability of the ANCD is versatile to the point of
operating application programs under Digital Research Disk Operating System (DR DOSTM). Thus, the ANCD, in a
general sense, can be considered a hand held PC. All application software is required to be cryptography signed by NSA.

1-11. EQUIPMENT DATA AND POWER REQUIREMENTS.
Power is supplied to the ANCD via battery. The standard configuration pack consists of three 3-volt lithium batteries.
In emergencies, a 9-volt Alkaline battery may be used when the regular batteries are not available. The power
supply logic is contained on the COMSEC PWA and provides all of. the necessary operating and standby voltages.
Also, during battery changes this logic maintains the backup power to RAM for a minimum of two minutes. During
normal operational periods the battery is expected to last approximately 30 days, assuming that the ANCD is on for
approximately one hour and in standby condition for 23 hours each day.
1-12. PHYSICAL DESCRIPTION.
The ANCD case is weather resistant and a lid opens to provide access to a LCD display and keypad. A fill
connector, A Crypto Ignition Key (CIK) port, and a battery access cover are the only external openings to the sealed
case. The ANCD measures 1.97 inches (50 mm) in height, 6.343 inches (161 mm) in width, and 4.4 inches (112
mm) in depth. With battery and CIK installed the weight equals 1.5 pounds (.68 kg).
