Safety Instructions
Safety Instructions
-
-
Observe the VDE safety regulations!
Observe the admissible maximum level when feeding signals.
A maximum of 0.5 watts of total power may be applied to the RF input.
Only fuses which have the same cut out characteristic may be used.
The unit is also live when disconnected.
In order to avoid electromagnetic interference, the unit may only be operated
with all screening covers and in a closed condition. Furthermore, make sure
that only suitable shielded cables are used.
There is a danger to life during mains operation when the unit is improperly
tampered with!
Connections
Faulty wiring can lead to operating disturbance or defects.
Proper use
The operator must make sure, that
·
the signal meter is only used in accordance with the requirements,
·
the signal meter is only operated in a perfect, functional condition,
·
the safety instructions and warnings on the signal meter are not removed and
remain legible.
Mechanical loadbearing capacity
The MSK 33 is designed for mobile use and the mechanical demands made there.
After strong mechanical loads such as collisions, hits or drops, the MSK 33 may
no longer be used because this could damage the unit.

With Sat/TV/FM signal meter MSK 33, detailed quality assessment of DVB-C,
DVB-T and DVB-S signals may be carried out along with level measurements of
analogue and digital TV and Sat reception signals. The unit is constructed in
modular technology, so future function extensions by means of plug-in cards are
easily possible.
The MSK 33 can be optionally supplied with power via the integrated lead accumulator of the integrated power supply unit (110…240 V~). A microcontroller is responsible for controlling the unit and scanning the keyboard entries with the hard
and softkeys as well representing the level and frequency on the integrated TFT
display screen. The high definition display screen allows a precise picture assessment.
Four different detectors for peak, average, maximal and minimal values are available for the level measurement of analogue and digital signals. Correction values
are determined by the level calibration of the MSK 33 and stored in an EEPROM.
This allows precise level measurements to be made with the MSK 33.
The MSK 33 is developed for the standards B/G, D/K, I, L, M, M Japan and Nicam.
The video signal can be processed and reproduced in the colour standards PAL,
SECAM and NTSC.
There is a bar display on the front display to help locate transmitters. In addition, a
level-dependent acoustic tracking signal simplifies the alignment of an antenna
without having to look at the screen.
The LNB supply voltage is 10 V…20 V for max. 500 mA in increments of 0.1 V.
For control of the receiving system, the 22 kHz signal as well as the commands for
DiSEqC 2.0, UFOµ-DiSEqC or V-SEC commands can be produced.
Level values, frequencies and plus the entire frequency spectrum can be printed
out via the integrated dot-matrix printer.

When installing the unit, ensure, that there is adequate heat dissipation.
To avoid heat build-up, the openings for the ventilators and the ventilation slots on
the top of the unit must always be free.
Use the leather case MZK 15 from Kathrein for mobile use.
Mains voltage / mains switch
The unit can be operated on AC current networks of 110...240 V with a network
frequency of 50...400 Hz. The unit is automatically set within the allowed voltage
range on the connected voltage.
The mains connection socket is located on the rear panel of the unit, and the mains
switch is located underneath the mains socket. As soon as the power supply is
connected, the green LED lights up on the front panel of the unit and the internal
accumulator is charged.

On/Off switch
With the On/Off button on the front panel of the unit, the MSK 33 can be switched
on and off. When the MSK 33 is switched off with this button, the last unit setting is
stored and activated again when the unit is switched on again.
Safety fuse
For exchanging the mains fuse, please proceed as follows:
·
Before exchanging the fuse, the power supply to the unit must be disconnected.
·
First, remove the fuse holder . To do so, insert a screwdriver into the designated gap and pull out the fuse holder.
·
After exchanging the fuse, reinsert the fuse holder into the unit.
Only use the following fuse types for the MSK 33:
F1: IEC 127 T1 A / 250 V
Despite mains separation, the unit can still contain voltages via the battery!
21
Accumulator and Battery Operation
Accumulator and Battery Operation
Accumulator operation
The accumulator of the MSK 33 is not charged in delivery status and must be
charged before initial operation. To do so, connect the unit with the mains, and
switch on the power supply with the mains switch on the front panel of the unit.
When the green LED on the front panel lights up, the accumulator is charged. The
charging time of an empty accumulator is about 6-7 hours.
After a complete discharge or during longer pauses of operation, the accumulator
must be recharged as soon as possible, otherwise the accumulator may be damages or even destroyed.
The charging procedure automatically starts after the unit has been connected to
the mains and switched on. Overload of the accumulator is not possible.
An internal over-discharging guard circuit automatically switches off the unit at a
capacity of 0%.
The maximal operating time with a charged accumulator is ca. 80 minutes (without
LNB voltage supply). For the LNB supply of 200 mA, the accumulator operating
time is about 1 hour.
The unit should be connected to the mains during longer pauses of operation (conservation of the battery).
Improper handling of the accumulator can damage the unit and result in total
breakdown.
The loading status of the built-in lead accumulator can be determined in the main
menu. The following displays are available:
Operating mode
Mains
Battery
Loading status charging-discharging current
CHARGING : 53% I = 0.76 A
ACCU CAP. : 90% I = -1.30 A
DC socket (option)
The DC socket (XLR socket) is located on the rear panel of the MSK 33. The unit
can be operated via this socket with a DC source of 11...14V (auto battery or power
supply unit). The charging of the internal unit accumulator is also possible via this
socket.
Here, disconnect the LNB voltage supply.
The operation of the MSK 33 guaranteed but not the charging of the internal
accumulator.
Only use the supplied cables with the original connectors.
If the external DC voltage decreases below 11 V, the MSK 33 automatically
stops the loading process of the internal battery and operation via the external power supply. As soon as the fed –in voltage reaches 13.5 V, the MSK 33
switches over again to external DC operation and charging of the internal accumulator. This function is indicated by the green LED on the rear panel of
the unit.
22
Connections
Connections
RF output
% # 9
The receiving signal is fed into the RF input socket (BNC socket). It delivers also
the remote power feeding voltage.
The remote power feeding voltage is adjustable and disconnectable from 10 to
20V. For control, the red LED over the RF input socket lights up when the LNB
voltage is switched on. The green LED underneath the input socket lights up,
when the MSK 33 is connected to the mains.
Make sure that,
- no voltage level over 130 dBµV,
- no positive DC voltage over 30 VDC,
- no negative DC voltage and
- no AC voltage over 70 VAC
is connected to the RF input socket.
Exceeding these values can damage the input stages and the unit!
Headphone connection
In order to better assess the sound quality, a connection of stereo headphones to
the 3.5 mm jack socket (rear panel, position 7) is possible. The MSK 33 provides a
stereo signal in Sat and TV operation and for FM a mono signal, each according to
the transmission type, on the headphone connection.
Modem / RS232 interface
The serial interface RS 232 is designed as a 25-pin SUB-D socket. It requires a
new software for controlling the MSK 33 and charging.
Scart socket
AV
A monitor or television set (video or RGB) can be connected to the Scart socket. It
is possible to feed in a video signal via the Scart socket and watch a picture on the
MSK 33. For the connection of a decoder, the Scart socket can be configured as a
decoder socket (Menu AV), in order to receive encrypted signals.
Occupying the Scart socket is shown in the chapter, „Technical Data“.
Socket TS PARALLEL (optional)

is moved between two carriers or in frequency gaps. The C/N measurement is carried out in medium or small span.
The softkey (yellow marker) must display the setting „dig.“
For noise bandwidth matching, the symbol rate set in the SAT or TV menu (for
DVB-T the chBW) is used. It must have been set for the C/N measurement in the
SAT range to 27.5 MS and in the TV range to 6.9 MS (at DVB-T to 7 or 8 MHZ).
Carry out the C/N measurement for the satellite reception directly behind the LNB.
For systems with cable slope, the measurement result can be incorrect, if the C/N
measurement occurs for subscriber connection.
For analogue or digital C/N measurements, the symbol rate in the SAT MEASURE
menu must be set to 27.5 MS. The noise measurement bandwidth is based on 27.5
MHz.

The function constellation diagram can be called up in the operation types, SAT
(DVB-S), TV (DVB-C and DVB-T), TV-IF or return path (DVB-C). Operating the
constellation functions is principally the same in the various operating types. The
differences are described below.
Colour representation of I/Q value pairs
The colour representation of the I/Q value pairs should
simplify the analysis of the constellation diagram in regards to
the occurring error. The colour of the I/Q value pairs changes
with the number of hits on one point within the decision field.
In an ideal case, the I/Q value pairs are always in the middle
of the decision field. However the I/Q value pairs are
influenced by interference on the transmission paths or in the
modulator on the transmitting side. As long as the I/Q value
pairs lie within the decision waves, a clear relation of valence
in the receiver can occur. The decision field is subdivided into
signal subsurfaces, also called pixels. For a black/white
representation, one could not represent the frequency of the
hits of a I/Q value pair on the surface of a pixel. The colour
representation of the MSK 33 allows the frequency of the hits
of a I/Q value pair on the surface of a pixel to be described by
the changing of colour. If many I/Q value pairs meet on a
pixel, RED is represented, however if very few I/Q value pairs
meet on a pixel, blue is represented. Four colours are available for the assessment of the „scores.“
RED – very many hits
YELLOW – many hits
GREEN – few hits
BLUE – very few hits
Constellation diagram for QPSK (DVB-S)
For the digital transmission via satellite,
the modulation type QPSK (Quadrature
Phase Shift Keying) is used. Every 2 information bits are put together to one
symbol and modulate one carrier in its
phase. With this, four conditions are possible, which a receiver must recognise.
A crosshair with four clouds, which represent the possible symbols or their frequency in the quadrants appear on the
colour screen.
Measurement of the bit error rate (BER)
Since it deals with transmission of binary data for DVB-S, the bit error rate can be
considered as measurement for the occurred transmission error in the data stream.
In the MSK 33, a BER measurement is carried out before the viterbi decoder and
displayed on the screen. The bit error rate is the ratio of the number of received defected bits divided by the entire number of the received bits. The lowest bit error
72
Const Menu
rate, which the MSK 33 can measure, is 1.0 e-8. If the rate is lower than these
values, the display of the BER jumps to zero „0“ (no longer bit error). The highest
BER, which can be displayed, is 1 e-2. Generally, it can be assumed, that picture
disturbance can occur by a BER of ca. 1 e-3.
Measurement of signal noise ratio (SNR)
The conception of the MSK 33 allows the S/N ratio of the I- and Q- data stream to
be displayed in addition to the C/N measurement on the digital carriers in the
Const-menu. The measurement is carried out after the QPSK demodulation and
can be called in as an indicator for the noise on the I/Q signals. Differences in the
result to the C/N measurement in the spectrum menu can be caused by the complex interfering influences of the digital signal or by differences in the input level.
The SNR value is displayed on the upper edge of the TFT screen.
The best value, which the MSK 33 can measure, is 12 dB. If the value is better
than 12 dB, this is indicated with a arrow in front of the measured value.
Carrier offset
The carrier offset display represents the difference between the set receiving frequency on the MSK 33 and the transmitting frequency of the digital signal in MHz.
The carrier offset is displayed on the upper edge of the TFT screen.
With the cursor buttons, ◄►, the receiving frequency of the MSK 33 can be
changed and the frequency offset can be set to zero. The carrier offset displays,
which frequency position the LO of the used LNB has.
Frontend locked
If the receiving unit of
the MSK 33 is locked on
the carrier frequency of
the received signal, the
display „frontend locked“ appears on the
screen. „Not locked“, appears in the
display, if a representation of the
constellation diagram is not possible. An
analysis of the constellation diagram or an
assessment of the measurement results
can first occur, as soon as the receiving

Constellation diagram for QAM (DVB-C)
For digital transmission via cables, the
modulation type QAM (Quadrature Amplitude Modulation) is used. The MSK 33 can
represent the constellation of the modulation types, QAM64 and QAM128. For
QAM 64, every 6 information bits are put
together to one symbol and modulate one
carrier in its amplitude and phase. With
this, 64 conditions are possible, which a
receiver must recognise for correct assessment of a QAM signal.
A „chessboard“ with 64 or 128 clouds,
which represent the possible symbols or
their frequency in the fields, appears on
the colour screen.
You can select the menu items by pressing the buttons on the right of the screen.

pressing the appropriate softkey. The buttons are represented in yellow for activated functions. Buttons, which have multi-functions, are indicated with an arrow
and are represented in yellow as well. By repeatedly pressing the same button, different parameters can be called up and displayed.
Measurement of the bit error rate (BER)
Since it deals with transmission of binary data for DVB-C, the bit error rate can be
considered as measurement for the occurring transmission error in the data
stream. In the MSK 33, a BER measurement is carried out before the error
correction and displayed on the screen. The bit error rate is the ratio of the number
of received defective bits divided by the entire number of the received bits. The
lowest bit error rate, which the MSK 33 can measure, is 1.0 e-8. If the rate is
lower than this value, the display of the BER jumps to zero „0“ (no longer bit error).
The highest BER, which can be displayed, is 1 e-2. Generally, it can be assumed,
that picture disturbance can occur by a BER of ca. 1 e-3.
Measurement of modulation error rate (MER)
In the DVB measuring guidelines, the measurement size is determined, which are
combined with the broad interfering influences. The MER is calculated to record the
entirety of the signal interference, which is available on the input of this receiver. It
gives instructions regarding the ability of the receiver, to decode a signal correctly.
The MER is the ratio of the average signal performance divided by the error power
in dB. The higher the MER value is, the better the received signal is. Measurements of the MER can be displayed on the upper edge of the screen.
Carrier offset
The carrier offset display shows the difference between the set receiving frequency
on the MSK 33 and the transmission frequency of the digital signal in MHz.

data for DVB-T, the bit error rate can be
observed as measurement for the occurring
transmission error in the data stream. The
BER measurement is carried out before the
viterbi decoder and displayed on the screen.
The bit error rate is the ration of the number
of the received defective bits divided by the
entire number of receive bits. The low bit
error rate, which the MSK 33 can measure, is 1.0 e-8. If the measured value is below this value, the display of BER skipped to zero „0“ (no bit error available). The
highest displayed BER is 1 e-2. Generally, it can be assumed, that the picture disturbance can occur for a BER of ca. ca. 2.2 e-2.
Measurement of signal noise ration (SNR)
The conception of the MSK 33 allows the S/N ratio of the I- and Q- data stream to

Broadband Cable Analysis Measuring System MSK 33 /
MVG
Broadband Cable Analysis Measuring System MSK 33 / MVG
The broadband cable analysis system consists of the antenna
measuring instrument MSK 33 (including return path option) and the
signal generator MVG 10.
Both units function in the frequency range from 4.0 MHz to 860 MHz.
It allows the measurement of cable systems in CATV range (downstream) and in the return path range (upstream).
The measurement can also be carried out in the supplied cable.
The signal generator MVG 10 can wobbulate in many segment
ranges, which means that ranges which are occupied can be locked
by the generator, thus allowing TV reception not to be disturbed.
Therefore, before the measurement, make a frequency and level plan!
The MVG 10 requires a bandwidth of ca. 500 kHz for transmitting the
telemetric data, which means, that the set frequency points must have
at least a distance of 250 kHz from the used signal on the cable system, provided the amplitudes of the used signal and MVG 10 signal
are the same.
Before each frequency change, the MVG 10 transmits the next reception frequency to the MSK 33 via a telemetric signal. In occupied
ranges, which must not be swept, the MSK 33 can carry on the measurements in the same raster with maximum scanning speed. During
this time, the MVG 10 pauses. The MSK 33 measures the transmitted
level and represents in the spectrum. the measurement can be printed
out via the built-in printer.

Modem / RS 232 interface
The serial interface RS 232 is executed as 25-pin SUB-D socket. it is required for
controlling the MSK 33 via mode, or PC.
Connection cable for modem / RS 232
In order for he MSK 33 to be able to be remotely controlled via the RS 232, a connection between the signal meter and the PC or external modem must be established. if a modem is used, this connection occurs with a RS 232 interface cable,
which connects the modem with the RS 232 socket on the rear panel of the MSK
33 1 : 1.
If a PC is directly connected, a so-called zero modem cable must be used. Here
next to the transmitting and receiving wire, all handshake wires are also crossed.
Note: For deactivating the handshake operating on the MSK 33 (see below), it is sufficient to use a zero
modem cable, in which only the TVD wire and the RXD wire are crossed. However, the operating software
of the MSK 33 works faster, if the handshake
operation is activated (especially, if no modem
is connected). The MSK 33 first answers
without handshake after the entry of a RETURN on the PC.

Connection assignment of the zero modem
cable for the remote control of the MSK 33 via

If the MSK 33 is directly connected with the PC, it is represented in
the upper display field in the ‚modem menu,‘ if the zero modem cable
is properly connected. All three displays (DSR, DCD and CTS) must
show the message „ON“. Many zero modem cables have no connection with the DCD connection of the RS 232 connector. If so, the
display ‚OFF‘ appears near the DCD. In this case, a bridge from DSR
to DCD must be provided in the connector of the zero modem cable
(refer to illustration) or the handshake operating must be switched
off.

Setting baud rate
rate
< >
The field lights up yellow, as soon as the softkey is pressed. Afterwards, the interface speed from 2400 to 115200 baud (each 8 bits / no parity /no stop bit) can be
set with the aid of the cursor buttons, „<„ and „>.„ This setting is only based on the
interface communication between the modem and the MSK 33 and has no influence on the transmission characteristic data of the modem.
Setting local echo
echo
off
Normally, all characters received by the modem are sent back by the MSK 33. This
means, that a character entered in on the terminal (PC keyboard) is not immediately displayed on the screen, but rather sent via the near modem (on the PC) to
the farther modem (on the MSK 33). Here, the character is analysed and sent
back (echo function).
If the local echo on the terminal is activated, the character appears twice and one
of the both echoes must be terminated.
Setting hardware handshake
r/cts
off
By pressing the button, R/CTS, the hardware-handshake can be activated or deactivated. If the handshake operation is deactivated, it is not possible for the MSK 33
to recognise, when a connected PC or modem has taken over the operation. In this
case, the MSK 33 first answer after entry of a RETURN on the terminal programme.
If the handshake is activated, this occurs automatically, as soon as the terminal
programme has been called up or the modem has been successfully called. If the
MSK 33 is switched off during this procedure, it will switch on by itself or switch off
after exiting the terminal programme or loss of the carrier on the modem.
Init (Initialisation string) for the MSK 33 modem
init
< >
90
Here, the currently valid initialisation string for the MSK 33 modem can be read.
With the aid of the initialisation string, a connection to the MSK 33 modem is established after switching on the MSK 33. With this, a change of the basic setting in the
modem is carried out, for example the setting of a common baud rate. A change of
the initialisation string can occur after pressing the INIT button. Hereby, it is possible to select the character with the cursor buttons, or to select the position which is
to be edited. The character string is sent to the first space after deactivating the
INIT button.
Interfaces
After pressing this button, the MSK 33 is reset to the factory setting.
Code (Password)
Here, the currently valid password can be read, which must be known by the used
for the remote request or control of the MSK 33. The password can only be
changed in active modem operation.
PIN1
is the master PIN and opens all functions of the MSK 33
(including download of the unit software). Just in case,
you should not register yourself under this PIN, in order
to avoid overwriting the programme software (other safeties are built in).
PIN2
opens all function of the MSK 33 with the exception of
locking the programme memory and the new programming of programme memory. The important settings on
the MSK 33 can be remotely controlled with this.
PIN3
allows one to only receive measurement values form the
MSK 33. The changing of important settings is not possible after login in under this PIN.
Note: For changing a PIN (only possible via RS232), the
PIN is always taken over, under which you have loggedin with.
Operating of the MSK 33 via modem
The MSK 33 can be remotely controlled in two terminal modes. It is distinguished
between the TTY mode and the ANSI mode.
The TTY mode
The TTY mode is line-orientated and complies for the most part with the usual operation via a serial interface or a modem. This means, the command abbreviations
are entered in via the keyboard, interpreted by the MSK 33 and the command is
appropriately executed. MSK 33 confirms the execution of the commands with text
information- After each command, the screen is scrolled up line-by-line. This
method is used in general for the automation of measurement tasks. A written
measurement programme from the user cyclically calls up certain commands of the
MSK 33 and analyses measurement values sent by the MSK 33.
the ANSI mode
In ANSI mode, it is possible for the MSK 33 to generate a intuitively easy to use
surface by simple control characters on the controlled page, which is in the SAA
standard under DOS. A advantage of this method is that any terminal programme
for controlling the MSK 33 can be used (e.g. Term95, Telemate, Hyperterminal
etc.). The installation of a separate control software on the PC is not necessary.
Other control computers can also be used as well. Here, The available control
characters in ANSI standard are fallen back upon a subset.
The log-in procedure
The MSK 33 responds to the user with the request of the password (PIN), after a
carrier has been recognised on the modem or for deactivation of the handshake after the entry of RETURN on the terminal programme. If no PIN is available (all positions of the respective PIN in the modem menu of the MSK are highlighted yellow), here RETURN must be pressed once more for confirmation.
91
Interfaces
Requesting help
In the TTY mode, the list of the available commands can be requested with the
question mark. In this list, the first three letters are capitalised, which should indicate that it concerns a key abbreviation. The entry of the first three characters the
command (occurs with RETURN) is here sufficient to trigger the respective command. If it concerns commands without parameter entry (calling up measurement
values or switch-over of specific modes etc.), the command is switched off. For
commands with parameter entry e.g. FRE (for receiving frequency entry), the request of the frequency appears after the command abbreviation by the MSK 33. It
is also possible to add the parameter (here the frequency) to the command
abbreviation as an attachment (separated by a space). Example FRE 266.25 MHz.
The command must be here entered in with a point. Units are proposed as default
and must only be added for a difference. Example FRE 10.7 G means 10700 MHz,
FRE 10.7 however 10.7 MHz. It is sufficient to type in the first letters of the unit
In ANSI mode, context-sensitive help is switched on. This means, that the user receives notes concerning the command selected from the pulldown menu, which
appear on the lower section of the screen.
Example for logging-in in ANSI mode
In ANSI mode, it is possible, to type in the commands, like in TTY mode) as command abbreviations, to select the commands from the pulldown menus with the
cursor buttons or to call up the commands via the button combinations.
In order to select from the pulldown menus, any cursor button must simply be
pressed. Now with the cursor buttons, the menu can be selected (left-right cursor)
or the command in the menu (up-down cursor) can be selected and with RETURN
the selection can be confirmed. The pulldown menu can be opened with the CONTROL + highlighted cipher, in order to then select a command with the highlighted
letter. Example: For frequency input, press CONTROL + C and afterwards F.
92
Interfaces
Note: Alt + S + cipher is in general base on functions of the respective terminal
programme.
The picture of the left shows an
example of a pulldown menu. On

Maintenance
The maintenance of the unit is confined to cleaning the interior and exterior of the
unit.
Unit calibration
The calibration interval depends on the use and demand, and should be made
every 1 and 2 years. The calibration can be carried out by the KATHREIN customer service centre (see below).
Exterior cleaning
The exterior of the unit is cleaned when needed with a soft, not fibrous dusting rag
or brush. For very dirty areas, a spirit or mild soap agent can be used. Never use
solutions such as nitro-thinner, acetone etc, because these could damage the writing on the front panel or the plastic parts.
Interior cleaning
The unit should be regularly dusted in the exterior every 1 to 2 years to ensure
adequate ventilation. The cleaning interval depends on the amount of dust of the
operating space. The housing cover is removed for cleaning the interior of the unit.
The dust can be removed with the brush or with compressed air.
Function testing
It is recommended to check the given required data in the measured time intervals.
The data and its tolerances are taken from the data sheet.
Required means of measurement:
- TV / Sat test signal generator e.g. Grundig VTG 700
- DVB test signal generator e.g. Rohde & Schwarz SFQ
Exchange of components
The modular construction principle of the MSK 33 allows an exchange of components by the user. Contact our service centre before each component exchange.
Storage
The storage temperature range of the unit is: -40...+70°C.
When the unit is stored for a longer period of time, it should be protected from dust.

General notes:
Observe the bold lines. The non-bold notes can only help you solve a problem in
cases of error. <RET> means to trigger the command with RETURN on the terminal programme.
1. Copy the file „MSK33.BXX“ (XX stands for the version number) from the
diskette into an easily found directory of your hard disk.
2. Connect the MSK33 with the PC via a zero modem cable (see respective
section). Set the baud rate to 19200 baud in the MODEM menu (SETTING /
MODEM). Note down the PIN (If no entry is available, PIN1 is <RET>).
If problems occur when using a 9-pin serial interface, the hardware handshake
(r/cst) can be set to OF in the MODEM menu.
3. Switch off the MSK33, and press down any number key on the MSK 33.
Start a terminal programme (we recommend Term95 in DOS mode) on
the PC => MSK33 switches on.
For switched of hardware handshake, the MSK 33 must be switched on by
hand.
Note: When using the terminal programme, Hyperterminal, under Windows95,
we recommend to use the fonts TERMINAL STANDARD 14 and OEM/DOS.
Set emulation to automatic recognition or ANSI.
4. the MSK 33 answers now with the bootloader „MSKUL>„. Enter in PIN1
and confirm the entry with <RET> (Standard PIN1 is-MSK-33-).
For switched off handshake, the MSK 33 first answers after entry of <RET>. If
the MSK 33 answer with „MSK 33>„ instead of „MSKUL>„, it must have been
changed in the upload operating with the command, UPL<RET>.
Note: With the command, LAN<RET>, you can change the language.
5. With the command UNL<RET>, the FLASH is released for programming.
Afterwards switch the MSK 33 to reception with the command,
BIN<RET>.
If the message is given from the MSK 33, that the access is refused, you may
have tried to log-in with PIN2 or PIN3. In this case, start over with step 1.
6. Now, start the upload of the file „MSK33.BIN“ on the terminal programme.
This occurs in the XMODEM mode (at 19200 baud ca. 3 minutes).
ATTENTION: Of the upload is not started within a certain period of time, the
MSK 33 locks up. In this case, you must start new from step 5 (command
UNL, BIN).
7. After the upload, the uninterrupted transmission is confirmed by the MSK
33.
In the RAW-mode, the message is given after the successful download, that
232144 characters were downloaded.
8. Ext the terminal programme, switch off the MSK 33, switch on the MSK 33
on again without terminal programme and set fact.setup in the menu,
SETTING / SYSTEM.
