Operator Manual
User Information
Purpose of the Manual
This Manual provides all information the operator needs for data link operation with VLF>HF Re>
ceivers EK 895 and EK 896.
All functions and commands marked with a crossreference to the User Manual 6045.6712.12.xx are
possible in data link operation; however, they are not essential for the actual data link operation.
Not included in this Manual are the necessary information and instructions concerning the instal>
lation, putting into operation and control of the unit, and troubleshooting instructions down to
module level. For this the User Manual 6045.6712.12.xx is required which is supplied as an acces>
sory.

BIT In the BIT (built>in test) it is checked whether all modules of
the basic unit are installed and operative. If required, error
messages are output which may also inform on the operating
status of the installed options. In addition, the Tx and Rx paths
are checked. The BIT is initiated either through switch>on or on
purpose during operation by pressing softkey BIT in the MAIN
menu.
CM In CM (continuous monitoring) all important equipment
functions are permanently monitored. This check is automatic.
Error messages are output following which the operator can
initiate the BIT to localize the fault.

(see Fig. 1.1 for EK 896 or Fig. 1.2 for EK 895)
1.1.1 General
Note:
In the text which follows only data link>
relevant functions are described. All other
functions are dealt with in the User Manual
(6045.6712.12.xx).
Local control is carried out via
f Keys with a fix function (hardkeys),
f Multi>functional keys (softkeys),
f Switches,
f Controls and a
f Tuning knob.
All essential receiver settings can be entered di>
rectly:
f Frequency
f Channel
f Modulation mode
The technical data stated in the data sheet are
guaranteed for frequencies as of 10 kHz.
f Entries outside the permitted entry range
will not be accepted.
f If within approx. 2 s no entry is made for
frequency or channel, the initial indication
will be displayed again.
For EK 895 only:
The softkeys obtain their different functions
either by selection from the menu (software)
or via previous actuation of the ENT key (separ>
ate functions menu 1).
The LEDs assigned to keys FRQ and CH indicate
which function the tuning knob and the nu>
meric keypad currently have an effect upon. If
the LED assigned to key FRQ is illuminated, the
stepwidth of the tuning knob can be altered by
means of the cursor control keys (Æ and ¨).
Once the maximum or minimum value is
reached, turning the tuning knob further will
have no effect on the indication (this does not
apply to the channel number!).
For entries via the numeric keypad the follow>
ing should be observed:
f Entries can be corrected at any time by ac>
tuation of key CLR.
f Entry of leading zeros is not required (0.04
= .04).
f Entry of zeros following the decimal point
is not required (1 = 1.000).
f Complete entries are to be terminated by
actuating key ENT or softkey ENT or NEXT.
6075.6991.82.01
For EK 896 only:
The softkeys obtain their different functions
either by selection from the menu (software)
or via key MENU 1 (separate functions menu 2).
The LEDs assigned to keys FRQ and CH indicate
which function the tuning knob and the nu>
meric keypad currently have an effect upon.

Operator Manual f General
If the LED assigned to key FRQ is illuminated,
the stepwidth of the tuning knob can be al>
tered by means of the cursor control keys (Æ
and ¨).
Once the minimum or maximum value is
reached, turning the tuning knob further will
have no effect on the frequency indication.
The key MORE only obtains a function if on the
right>hand side on the display the character
'>' appears.
Note:
The individual functions are called up via the
main menu.
A description of how the operator gets from
the individual sublevels back to the main menu
is not provided. Unrestricted control of the re>
ceiver is still possible with a particular function
being called up. If required, the main menu can
be called up again by pressing the key MENU
several times.

Operator Manual f Operating Modes
1.1.3 Operating Modes
The receiver can be operated in the following
two operating modes:
f MANUAL
f CHANNEL
> FIXED CHANNEL
1.1.3.1 MANUAL
In the operating mode MANUAL no channel is
set. In manual operation the following mani>
pulations are possible:
f Entry or modification of frequency
f Selection of modulation mode
f Selection of special function
f Selection of system function
f Selection of separate function
f Storage into a channel
f Clearing a channel
1.1.3.2 CHANNEL
In the operating mode CHANNEL there is a
channel set. In channel operation, the follow>
ing manipulations are possible:
f Channel call>up and scanning
f Editing the channel data
As soon as one of the basic settings (frequency
or modulation mode) is altered, the receiver is
automatically in the operating mode MANUAL
(see 1.1.3.1). That is, no channel will be indi>
cated.
Cleared (inhibited) channels cannot be called
up.
Only those channels are permitted to be called
up where one of the following modulation
modes is stored:
LL LU LIL LIU
In the MANUAL mode the different software
levels may be called up without affecting the
receive operation.
For all manipulations with the exception of sys>
tem reset, store and clear, the stored channel
contents remain unchanged.
Complete receiver settings, consisting of fre>
quency and modulation mode, can be stored in
a single channel.
1.1.3.2.1 FIXED CHANNEL
In the operating mode FIXED CHANNEL it is
possible to call up only those channels which
were previously stored. All other operating
functions are blocked. However, this does not
apply to remote operation.
The operating mode FIXED CHANNEL can only
be activated and deactivated by entering a
password.

value. If overwriting with a default value takes
place in a channel, this channel is additionally
inhibited.

Following initialization the LCD illumination is
switched on.
In the LED test the function of LEDs FRQ, BFO,
CH and NOTCH / PBT is checked.
The processor evaluates the BIT messages (BIT
criterion) from the HF unit as well as the CM
messages from the synthesizer and the IF / AF
processor.
As soon as one of the following messages is dis>
played, carry out troubleshooting acc. to 4.2

ation acc. to 3.1.19.7 (see User Manual
(6045.6712.12.xx). Switch receiver off and on
again.
In the LCD test all segments are switched on for
approx. 2 s and then switched off again. This
allows a visual check of the LCD.
In the built>in equipment test (BIT) it is first
checked whether the modules synthesizer, HF
unit and IF / AF processor are installed.
Subsequently a 100>kHz test signal is fed into
the receive path instead of the antenna signal,
and the receiver is set to a receive frequency of
100 kHz.
Once the BIT is terminated successfully, the last
receiver setting is reactivated and the main
menu is displayed. In the FIXED CHANNEL
mode the display CHANNEL MODE EXIT is indi>

within the frequency field (9) below any
of the displayed figures. This does not
apply to the 10>MHz place!
In addition the cursor (10) can be shifted
to the right and out of the frequency field
(9), as a consequence the freely pro>
grammed stepwidth (see 1.1.7.3 and
1.1.7.4) for the tuning knob will become
effective.

In the text which follows only the data link>relevant commands are described. All other com>
mands are dealt with in the User Manual (6045.6712.12.xx).
2.1 General
The commands entered on the computer have to be in a specific format. The format or the com>
mand block consists of up to 150 characters. Each command block begins with the ASCII character
LF (= line feed, 10
(= carriage return, 13
r<command block>?
in the following represented by r) and ends with the ASCII character CR
dec,
in the following represented by ?).
dec,
The ASCII character LF is followed by the equipment address in addressed operation or the first
command in unaddressed operation. Addresses from A01 to A99 are admissible. In addressed
operation the equipment address is followed by the first command.
Addressed operation
r<address><command 1><command 2> ... <command x>?
Command blocks beginning with the address A00 are accepted by all receivers, regardless of the
set receiver address.
Unaddressed operation
r<command 1><command 2> ... <command x>?
The command itself consists of a code and up to 21 parameters. Consecutive parameters have to
be separated by a comma. For parameter entry guiding zeros and the plus sign can be omitted.
<code><parameter 1>,<parameter 2> ... <parameter 21>
The code consists of up to five capital letters. The parameters may come as numerical parameter
(numbers and the minus sign), character (small letter) and the question mark. The question mark
(?) signals that a reply is requested.
The reply consists of the code followed by the question mark and the setting value(s). The
reply(ies) is (are) inserted into a reply block, the sequence is not required to be the same as for the
command block. The reply block begins with the ASCII character F (r) and ends with the ASCII
character CR (?). In addressed operation LF is followed by the equipment address. Leading zeros
are not integrated into the reply.
Consecutive commands without parameters are to be separated by a blank (in the following rep>
resented by
e.g.: r<command 1>≤≥<command 2>?
≤≥
).

Operator Manual f Operating Modes
2.2 Operating Modes
The receiver can be operated in the following
two operating modes:
f MANUAL
f CHANNEL
2.2.1 MANUAL
In the MANUAL mode no channel is set.
For the basic settings of the VLF>HF receiver the
following codes are possible:
f F (frequency)
f I (modulation mode)
The possible special functions are characterized
by the following codes:
f L (receive level)
f PL (level line)
f P (level line status)
f C (CM status)
f BI (BIT status)
f ST (storage into channel)
f K, CL, RS (editing of channel contents)
f PA (preamplifier)
f SE (switching digital selection on or off,
with FK 896 only)
The possible system functions are characterized
by the following codes:
f A (address)
f V (software version)
f FIB (IF filter)
f OP (options)
f SA (signal BYPASS)
f IF (IF signal)
f M (operating status)
f ERR (error status)
f RESET (software reset)
f REM (local control)
f IDENT (software type and Ident. No.)
Via the command Ks<parameter> a channel
can be called up, and the receiver is auto>
matically in the CHANNEL mode (see 2.2.2).
2.2.2 CHANNEL
In the CHANNEL mode there is a channel set.
In channel operation, as in the MANUAL mode
(see 2.2.1), it is possible to execute
f Special functions and
f System functions.
If one of the basic settings (frequency or
modulation mode) is altered, the receiver auto>
matically operates in the MANUAL mode (see
2.2.1).
