WARNING
VOLTAGES INSIDE THE HC-530/535 CIPHERING TERMINALS CAN CAUSE DEATH OR
INJURY. UNDER NO CIRCUMSTANCES SHOULD THESE UNITS BE OPENED WITHOUT
FIRST DISCONNECTING THE POWER CORD FROM THE MAINS SUPPLY. NEVER APPLY
POWER TO A UNIT IF IT IS OPEN.
WARNING
NEVER ALLOW A SHORT CIRCUIT TO OCCUR ACROSS THE TERMINALS OF THE REMOV
ABLE NICKEL-CADMIUM (NI-CD) ACCUMULATOR OF THE HC-530/535. THE LOW IN
TERNAL IMPEDANCE OF THE ACCUMULATOR WILLALLOW HIGH CURRENTS TO BE THEN
PRODUCED, WHICH CAN HEAT AND MELT CONDUCTORS, PRODUCING BURNS, FIRE
HAZARDS AND EQUIPMENT DAMAGE. FURTHER, SINCE NI-CD ACCUMULATORS CONTAIN
HIGHLY-POISONOUS CADMIUM, NEVER DISPOSE OF WORN-OUT ACCUMULATORS IN THE
GARBAGE, NEVER OPEN THEM AND NEVER BURN THEM. RATHER ALWAYS RETURN THEM
TO CRYPTO AG FOR RECYCLING.
CAUTION
BEFORE CONNECTING THE LINE CORD TO YOUR AC MAINS SUPPLY, ENSURE THAT
THE VOLTAGE SELECTOR SWITCH (FIGURE 3.1) IS SET TO YOUR LOCAL SUPPLY
VOLTAGE VALUE (110 OR 220 VAC) NOTE: THIS CAUTION DOES NOT APPLY IF A
DC CHARGER MODULE PSB-530 IS BEING USED; IT HAS NO VOLTAGE SELECTOR
SWITCH.

1. GENERAL
1.1 DESCRIPTION
The CRYPT0MATIC®HC-530/535 is a universal ciphering terminal for
mobile or stationary use. It serves primarily for the ciphering
and deciphering of text in the off-line mode, yet can also be used
for ciphered transmission directly over the line via serial or
coupler outputs.
The unit is available in a civilian version (HC-530), which comes
in a compact elegant Samsonite attache case or in a military ver
sion (HC-535), which comes in a ruggedized military-type case
(Appendix 1). Both units can be operated without being removed
from their cases.
The various text input and output possibilities as well as a
powerful microprocessor system give the units an exceptional
flexibility. Operation of the units is simple and logical.
The units will operate, due to their rechargeable, gas-tight
nickel-cadmium accumulator (batteries), for up to 5 hours in
dependently of the mains supply. A removable AC (or DC) charger
module allows mains buffer or charging operations at all times.
The integral printer can also be continuously operated from the
accumulator if ever necessary for a duration of approximately
0.8 hours.
The robust metal housing of the HC-530/535 gives excellent EMC
protection. The standard text memory is 2000 characters and an
optional version with 6000 characters is available. An independent
6000 character receiving memory is available for coupler recep
tion.

1.2 APPLICATIONS
The HC-530/HC-535 allows ciphering and deciphering of secret mes
sages. Messages may be transferred via the acoustic coupler, gal
vanic coupler or serial interface. The serial interface permits
output/input via various types of peripheral equipment such as a
tape punch/reader or a telegraph interface for a teleprinter.
1.3 CONSTRUCTION
The HC-530/535 consists of the following plug-in assemblies
(modules), Appendix A2:
- Alpha-numeric keyboard and display
- Thermo-printer
- Serial interface
- 5 printed circuit (PC) boards in EURO-format
- Couplers (acoustic and galvanic) with common modem
- Power converter PC board for internal voltages
- AC charger module
- A c c u m u l a t o r ( i . e . , r e c h a r g e a b l e b a t t e r y ) p a c k .
The connections between modules are provided mainly by ribbon
cables.
1.3.1 KEYBOARD
The keyboard of the HC-530/535 has four rows. An n-key rollover
function permits fast and error-free inputting. Each key is equip
ped with a mechanical contact which locks the key during opera
tion. The contact is gold plated and is located in a dust-proof
housing. The key caps are removable. The code correlation is pre
set in a matrix. All control and operating commands are entered
via the keyboard (by pressing the control key CTRL and another key
simultaneously).

The following warning signals are also shown (flashing display):
- an asterisk (*) alternating with text (indicates memory nearly
full)
- Blank display alternates with text (indicates that the Ni-Cd
accummulator is nearly discharged).
1.3.3 PRINTER
A robust thermo-printer is located in the HC-530/535. Printing is
in transverse format, i.e., along the long dimension of the
thermo-paper strip, providing clear easily-readable text. The
printer consists of a transport roller, a thermo-head with 100
printing points and a stepping motor with gearing. A pushbutton
for paper feed is located under the lid covering the printer. When
this pushbutton is operated the printer head is lifted and
mechanical pressure released. Paper feed can only be carried out
when the unit is in monitor mode (status M).
1.3.4 SERIAL INTERFACE
The serial interface serves for serial data input and output as
well as for test purposes. The asynchronous data input and output
signals are available in V28/V24 levels. These signals as well as
other signals are available on the interface plug in TTL level
(CMOS 5 volt). In addition, the supply voltages are fed to the
interface plug for test purposes. Serial data transmission speeds
can be selected from 50 to 1200 baud. It is also possible to em
ploy external clocks, whereby 16-fold bit rate can be applied.
The bit rates for input and output can be independently preselect
ed by means of an operator-controlled variable parameter program
ming mode. It is possible to work in either 5 bit Baudot code or
in 8 bit ASCII. In 8 bit code there are various format possibili
ties: with and without parity, 1 or 2 stop-bits as well as 7 or 8
data bits.

HAGEUN-CRYPTOS
3B945 ■■1- 5
CRYPTO AG
The serial interface pin assignments are given in Appendix A3.
1.3.5 COUPLERS
Various types of coupler operation are programmable
- Normal or
one time: 240 baud (48 characters per second)
- FEC (or
redundant): Multiple transmission with multiple decision
during reception. In this way interference inter
ruptions of up to approximately 0.5 seconds can be
bridged.
- Selective
Call: Individual addressing or group calling
1.3.5.1 ACOUSTIC COUPLER
The acoustic telephone coupler allows transmission of ciphered
messages over telephone lines. The design of the telephone coupler
allows coupling to practically all current types of telephone hand
sets. Transmission takes place synchronously.
1.3.5.2 GALVANIC COUPLER
The galvanic coupler is an electronic interface which allows tele
phone and radio communications with the HC-530/535 to take place
electrically, i.e., without conversion to an acoustic signal. The
galvanic coupler is supplied as part of the acoustic coupler op
tion and uses the same modem.
Switchover from acoustic to galvanic operation occurs automati
cally as soon as the galvanic coupler is connected to a telephone
interface (such as, e.g., the TFG-530 Telephone/Galvanic Switch
over Interface) or to a radio transmitter (both covered in Chapter
4).

HAGEUN-CRYPTOS
3B945 ■■1- 6
CRYPTO AG
The galvanic coupler allows data to be transferred completely
electrically thus avoiding background noise sources which can
negatively influence acoustic coupler reception.
The galvanic coupler pin assignments are given in Appendix A4.
1.3.6 POWER SUPPLY
The mains supply feeds the charger module of the HC-530/535. (By
"mains supply" is meant the 110/220 VAC source for the standard AC
charger module or the 10 to 30 VDC source for the optional PSB-530
DC charger module.) The HC-530/535 charger module works with a 24
volt nickel-cadmium (Ni-Cd) accumulator in buffer operation as
follows: The accumulator will charge regardless of whether the
HC-530/535 is turned on or off, but only when the HC-530/535 is
connected to the mains supply. When the printer is operating, how
ever, the accumulator helps the charger module supply power to the
printer; the accumulator will thus be discharging somewhat when
the printer is in use. (The accumulator can, of course, supply
power if both operation and printing when the mains supply is not
connected.)
Complete discharging of the accumulator during operation (unit
switched on) is not possible since a monitor control switches out
the accumulator as soon as the terminal voltage drops below appro
ximately 21V. For mains independent operation the unit should be
charged for 12 to 15 hours before use. This gives up to 5 hours of
normal operation or 0.8 hours of continual printing operation.
With a used accumulator these operating times are, of course,
reduced. The accumulator voltage is stepped-down by a power con
verter to provide the internal voltages (see also Section 4.6).
This power converter is equipped with over-current and over-
voltage cut-out devices. The over-current protection is provided
by a fuse. The charger module is also protected by a fuse on the
secondary side. The charger is fitted with a thermal fuse on the
mains side.

A separate 4.8V Ni-Cd accumulator protects the basic key and vari
able parameter memories. (This accumulator is mounted on the key
board and display PC board - Appendix A2.)
