1Overview about features
VSDxx is a pure digital crosspoint switch (resp. matrix switch) or digital DVI video signals. It simultaniously
connects up to eight DVI sources to up to eight displaying devices. For each video source, you can either use
a “point-to-point” mode (where you connect exactly one source to exacly one displaying device) or a
“point-to-multipoint” con iguration, where the video signal o one input is distributed to several displaying
devices.
Figure 1: typical application of VSDxx
You can operate the VSDxx by:
•manually using the ront switches (buttons)
•remotely using RS-232 control
•remotely using an (optional) in rared remote control (not included)
•remotely using the build-in webserver (and your pre erred internet browser)
•remotely using a telnet console
The VSDxx has a blue character display in the rontside aceplate, which normally shows the actual swic-
thing state, i.e. the current connections between the inputs and outputs. When operated remotely using
the web inter ace, the current switching state o the matrix is displayed graphically, with console control
(RS-232 or telnet), you can query the switching state using a command language.
When changing DVI connections between video sources and displaying devices, it is not only necessary to
switch the video connections/in ormations, but also to properly handle so called EDID-In ormation, which is
mandatory in the DVI standards. VSDxx will manage this automatically, according your setup con iguration.

2Setup and cabeling instructions
2.1 npacking
Please take VSDxx out o the shipping box, take away plastic shock protection and transportation bag. Strip
o ront panel protection tape, starting at one corner o the ront panel. Unpack power cord and all other
material supplied with the shipment, and keep it ready or use.
2.2 Packing list
Please check shipment or all parts, listed in the packing list below:
•one VSDxx-unit (size 435,0x260,0x44,0 mm)
•two side protection covers ( oam, white)
•one power cord, length 2m
•one serial RS-232 cable, length 2m, one side DSUB9 male, other side DSUB9 emale. Connected 1:1
•our black rubber stickers, to be attached, when unit is operated desktop
•optional (i ordered): one in rared remote control
•two 19-inch rack mount brackets, one with additional center cutout to support ventilation. This bag
will also have eight screws (black, M4x5mm).
•one operation manual (this document)
2.3 Operation location requirements
The VSDxx has an IP 40 degree o protection against dust and humidity (according to IEC529).
You have to ensure a mounting or operation location, where no danger o entering luids will exist.
Furthermore you must ensure compliance with the speci ied environment conditions (see chapter 8.2), es-
peciually temperature and relative humidity.
2.4 Setup and mounting
You can operate VSDxx „desktop“ on a shel or tabletop, by sticking the our rubber stickers to each corner
o the bottom o the VSDxx unit. With that stickers, small roughness o your table is compensated and the
unit will not slide away on lat sur aces.
Alternatively, you can mount the VSDxx into a 19-inch rack, using the brackets supplied. The mounting o
the brackets is simple, you just need a screwdriver (size PH2). Start on the le t hand side o the unit ( ront is
the side with the buttons, top is top when reading the ront panel tags correctly) and unmount the two
ront and the two middle screws completely. Take the one bracket with the center cutout and attach it to
the le t hand side o VSDxx, using the longer M4x5 screews contained in the bracket’s bag. A ter that, the
ventilation cutout o the VSDxx chassis should not be blocked signi icantly by the newly attached bracked.
Repeat procedure on the right hand side, using the remaining bracket.
When operated desktop or rack-mount, please ensure that nothing will cover the ventilation cutouts on
the le thand side o the unit.
2.5 Electrical connections
2.5.1 mains connection
Please attach mains cord (supplied with shipment) into the IEC-320 connector o the VSDxx. This connector
is located on the back side o the unit. Now plug the mains plug into the wall outlet o your installation.
The VSDxx has no power switch, it will immediately start operation when plugged into a “hot” wall outlet.
The unit will boot and ready or operation a ter 10..15 seconds.
The blue LED o the power button (caption: O/I, rightmost ront button) will be permanentely on, when
unit is powered and active. Each time, the main power ails and returns, the VSDxx will return to the
ACTIVE state!
As the unit has no main power switch, it will be ON after attaching the unit to a powered wall out-
let. To have the VSDxx de-energised, please detach mains power cable!
Never expose any cables to mechanical stress like strong bending or pull. This can damage cables
and impact security!

2.5.2 Attaching DVI video sources
Next step in setup procedure is attaching video sources.
To avoid damages is VSDxx and your existing video sources, all connections between components
are to be done when ALL units are powered off. Now ensure that you have powered off all video
sources and the VSDxx.
Now connect your DVI video sources to VSDxx, using your DVI-D-video cables (not with the shipment), one
a ter another. All inputs o VSDxx will be labeled with “Input 1” to “Input 8”. You are ree to use any input
you like or a speci ic source, all inputs are electrically identical.
It is a good idea to denote all input connections, i.e. which source goes to which input number.
You can use any DVI-D cable, with high quality cable you can have your video source up to 35m away rom
the VSDxx. Each input has a signal equalizer that re reshes the signal to standard levels.
I you are having your VSDxx licensed only with our inputs (i.e. VSD44 or VSD48), the inputs labeled “Input
5” to “Input 8” are out o unctionality and should not be used, i.e. you can not route signals rom these
inputs to any output. But there is not problem or damage, i you attach video sources there by accident.
Mechanically fix the connctions by using the screws of the male DVI connector. This will ensure
reliability of the system.
2.5.3 Attaching DVI displaying devices
Now connect your displaying devices (i.e. monitors, LCDs or beamers) to the outputs o the VSDxx, using
your DVI-D cables (not with the shipment). All outputs o the unit are labeled “Output 1” to “Output 8”.
Your are ree to use any o the available outputs or your devices, all are electrically identical.
Complete your written notes by denoting the output assignement, i.e. which output goes to which o your
displaying devices.
Use no DVI cables longer than 5 m as output cables when using maximum video resolutions like 1600x1200
Pixels.
I your are having a VSDxx licensed only to our outputs (i.e. VSD44 or VSD84), only “Output 1” to “Output
4” will be active. All other outputs will carry no active video signals, but provide signal levels according to
DVI standard.
Mechanically fix the connctions by using the screws of the male DVI connector. This will ensure
reliability of the system.
2.5.4 RS232 connection
I you intend to control the VSDxx matrix switch by a PC or Laptop using the RS-232 serial inter ace, please
connect the serial cord supplied to the DSUB9F-connector at the back o VSDxx, to the connector labeled
“RS-232”. The other end o the cable should be connected to the serial inter ace o your PC/Laptop. I your
equipment does not have a serial inter ace or connector, you can use either control by network/TCP or us-
ing a USB/RS-232 converter dongle available in some shops. You can ind pin connection diagram and con-
iguration data o the serial inter ace in section 8.1.5 o this document.
2.5.5 TCP/IP connection
Using a TCP/IP network connection, you can control VSDxx remotely either using a web inter ace or using a
telnet console session.
I you intend to use this kind o control, please connect a standard network cable ( or 100MBit/s CAT5 or
higher) to the port labeled “TCP/IP” at the rear o the unit and your network. The unit will support
10MBit/s and 100MBit/s TCP/IP networks, but does not have a so called “Auto-MDX”-mode, i.e. when you
like to connect it directly to a PC’s network inter ace, you have to use a “crossed” network cable or your
PC’s network adaptor must be capable o Auto-MDX.

2.5.6 Checking your cabeling
A ter doing all connections, you overall system (containing the VSDxx) should look like this:
Figure 2: VSDxx cabeling

3Operating instructions
3.1 Powering on/off, Standby-operation
When VSDxx is connected to a hot wall socket, it will start and boot automatically. All button LEDs will
lash or a short period o time and the text display will show a short welcome message ( rom the boot-
loader). A ter that, the unit trys to reach a TCP/IP network (i cable connected).
A ter 10 seconds max., the unit is up and ready or operation. The text display will switch to a “status dis-
play” mode (see igure 3). You can read all active routing connections rom that status display. All outputs
available are written in the top row, starting with “OUT:”. The lower row displays the number o the input
connected to the output above. A minus sign says, that the output has NO connection to any input. Read-
ing a number gives the number o the input channel, that is actually connected to the output.
Figure 4: Routing status display (example)
The example in igure 5 reads:
•Outputs # 1,4 and 6 are o
•Output #2 shows video connected to input #6
•Output #3 shows video connected to input #4
•Output #5 shows video connected to input #5
•Output #7 shows video connected to input #3
•Output #8 shows video connected to input #1
By pressing the “O/I”-button on roint panel longer than 3 seconds, the VSDxx will quit active mode and go
to a standby mode o operation. All active connctions break and the unit will turn o most o its internal
unctions.
I the unit is in standby, you can activate it by pressing the “O/I”-button longer than about 1 second. Then,
all previous routing connections are re-established (both video and EDID-connections).
3.2 Outline of operation
As mentioned shortly in chapter Fehler! Verweisquelle konnte nicht gefunden werden., the VSDxx can be
operated by di erent methods. These methods di er in complexity and level o control, so rookies and
pro essional users will ind their appropriate control method.
To ease handling o the VSDxx and have a quick start, let’s outline the next sections:
•make and break video routing connections
•save and recall setups scenarions with “presets”
•control system’s menu tree
•control system’s eatures through remote inter aces like console or web inter ace
3.3 Set up video connections between inputs and outputs
3.3.1 Making a connection
First, select the output number o the connection you intend to make by pressing one o the numeric but-
tons “1” to “8” (resp. „1“ to „4“, i you only licensed 4 Outputs). Now, the LED o the selected output will
lash slowly. And the cursor in the text display will lashg the number o the selected output channel.
Now pressing one o the numeric buttons “1” to “8” (resp. “1” to “4”, i you licensed only 4 inputs) will
make the connection to the selected input number. The ormer lashing LED will blank and the status text
display will show the newly established connection.
3.3.2 Modifying or breaking an existing connection
An existing connection can be modi ied by re-establisting a new connection/routing, just like described in
the previous section. I you intend to break an existing connection, just press the number o the output you
want to turn o (break connection), a ter the LED light lashing, press the “P”-button. This will break the

connection and turn o the LED. The text diplay will show a minus sign under the selected output number,
to show the “o ”-connection.
3.4 Save and recall of presets
You can save or recall a routing setup any time you like. By saving a preset, you can preserve a complex
setup or later use. By recalling a setup, you can switch several channels synchronously.
3.4.1 Saving a preset
For preserving the routing state o VSDxx, i.e. which inputs are connected to which outputs, VSDxx system
o ers eight so called “presets”. These presets are non-volatile, i.e. even a ter power-loss you can restore
your system routing, i you have saved it to a preset bank be ore.
To save a setup as preset, make all connections you like to do. Then press the “P”-button (“P” like preset)
longer than a second. The text displays then switches to the “PRE-SAVE” mode, like in igure 6.
Figure 7: Saving a preset
The display now shows eight available preset banks (storage locations) in the top row, the lower row shows
the usage status o the bank. A carret says, that the preset bank is already used, but can be overwritten, a
minus sign says, the preset bank is ree.
The cursor and the eight LEDs (on the eight numeric buttons) invite you to select the preset bank you de-
sire, by pressing the appropriate numeric button. A ter sucess ully selecting a preset bank, the text display
will return to the status display o igure 8 and all lashing LEDs will stop lashing.
I you like to cancel saving instead, just press the “P” button instead o one o the numeric buttons. Then
preset save dialog will be canceled and text display will return to standard status display o igure 9.
Attention:
•Only the actual routing in ormation will be stored into a preset bank. No EDID-content will be
saved (and recalled later) using the preset unctions!
3.4.2 Recalling a preset setup
To load (recall) a saved preset , just press the „P“-button shortly. The text display will switch to a “PRE-
LOAD” mode, as printed in igure 10.
Figure 11: Loading a preset
Like when saving (see section 3.4.1), the top row will display all eight preset banks, the lower row will show
all used banks with carets, unused ree banks are shown as minus sign.
All LEDs o those numeric buttons will lash slowly, that represent used banks, i.e. those banks that can be
recalled. Just choose the preset number desired by pressing the numeric button on the ront panel. The
load process is immediate, i.e the video routing is modi ied immediately according to the saved routing
con igurations. A ter success ul loading, the text display will return to status display mode like in igure 12.
I you like to cancel the recall process, just press “P” button instead o one o the numeric buttons, then the
text display will return to standard status display and LEDs will stop lashing.

3.5 Menu functions
3.5.1 Menu system
Using the built in menu system, more complex system unctions are available.
To handle the menu system, you have to use the our cursor buttons (arrows up, down, le t, right) and the
“enter” button, located right o the “right” cursor button. With those buttons, you can navigate through a
menu tree, to access more complex system unctions.
To operate the menu, these “rules“ apply:
•The menu will open a ter you press the “right”, “up”, “down” or “enter” butten, i the text dis-
play is showing the standard status in ormation like in igure 13.
•Using “up” and “down” buttons, you can navigate through the menu items. I there are more than
two menu items, advancing in one direction will scroll the menu tree.
•The current, active menu item will have a blinking cursor in the rightmost column o the text dis-
play.
•A ter pressing the “right” or the “enter” button, the active menu unction is exectuted or a sub-
menu is opened, depending on the menu item.
•Using the “le t”-button, you can close a submenu or quit a unction, returning to the next upper
menu, or even closing the menu system, i you are already in the topmost menu level.
•For certain unction, the menu system has “option” unctions, i.e. you are allowed to select one o
several possibilties. With “up” and “down” you scroll through the options available. The actual se-
lected active option has a caret in the rightmost column o the text display. You select your option
by navigating to the line with your option, then pressing “right” or “enter” button.
•For menu items requiring numerical entry (like IP adresses), you will have a cursor and be able to
modi y each digit with the “up” and “down” keys and navigate through the positions with “le t”
and “right” keys. Pressing “right”at the rightmost position o entry, you will acknowledge your en-
try, leaving entry “le t” will cancel your input.

3.6 Console and TELNET access
3.6.1 Introduction to Console/Telnet
Console and Telnet connection to the unit is di erent in terms o electrical connectivity, but both access
methods share the same command set and handling.
For serial remote control, please use the serial cable shipped with the unit. The cable is to be connected to
any available serial port (i.e. COM1) o your PC/Laptop. At the unit, please attach the serial cable to the
DSUB9-connector labeled „RS 232“ on the back side o the unit.
The serial inter ace parameters are 57600 8N1, which is:
•bauderate: 57600 Baud
•data bits: 8
•stop bits: 1
•parity: None
You can use „Hyperterminal“ which is shipped with Microso t Windows® operating systems or any other
terminal application programs available on you operation system pre erred.
For Telnet connection, please attach the unit to your local network (LAN) via a STP/UTP cable (not included
with the unit). At the unit, use rear connector labeled „TCP/IP“. Any TCP/IP network with 10MBit/s or
100MBit/s is supported. Please re er section 3.5 or adjustion network connectivity via menu buttons/ ront
panel or use a serial console connection (and commands listed below) to adjust network parameters corre-
cly. I your LAN is supporting DHCP, then the unit will be assigned automatically and you simply can read
the IP adress assigned with ront panel menus (Status/Network Status/IP).
To control unit via TELNET, please use a special telnet application like „PUTTY“ or use the windows com-
mand line „telnet aaa.bbb.ccc.ddd“ while using the unit’s IP adress as aaa.bbb.ccc.ddd in dotted numerical
ormat, i.e. „telnet 192.168.0.100“.
Both access methods (serial or telnet) will open a console application, where you can type in commands and
get back replys.
First o all, you have to authenticate to the unit, because con iguration access is protected with password to
avoid unauthorised use o the unit. By de ault ( actory setting), login is possible using:
Login: any
Password: any
Please mind upper case / lower case writing. Any command line ends by typing the ENTER-key at your key-
board.
Here are some hints or console control:
•you can add additional users using the „sys_addusr“ command (see below)
•you can get a list o all commands available by typing „help“ or „?“
•a short help message to any command is available by typing „? <command>“ where <command> is
the command string you’re interested in. Don’t orget the space in between the question mark and
the command.
•Issueing „exit“ command will log o serial console (you have to re-login) respectively will close the
TELNET session.
3.6.2 Console command description
3.6.2.1 edid_clear
Format: edid_clear N
Clears the content o EDID-bank #N. All EDID in ormation stored is discarded. Caution: there is no request
dialog, command is executed immediately.
3.6.2.2 edid_list
Format: edid_list
Lists the usage status o the EDID banks. I a bank contains no EDID in ormation, the status is „empty“. I a
bank is used, the EDID monitor name (i available) o the bank content is displayed. I there is no name
contained in the EDID data but valid EDID data (i.e. checksum is OK), just „valid“ is displayed as bank status.

Using the web inter ace o the unit, you can even assign a own name o the bank, but this is not avalable
via Console or Telnet.
3.6.2.3 edid_mode
Format 1: edid_mode
Displays the behavoir o EDID/DDC or each input. This is a typical printout ( actory setup):
IN: 1 2 3 4 5 6 7 8
DDCM:S S S S S S S S
When reading the example, the irst row will list all inputs available at the unit and the second row will
show a character abbreviation or the input number the row above.
All eight inputs (o the example) are con igured to „S” (=STATIC).
Please use this table or interpretation o the abbreviations used:
char EDID-mode
- OFF: no EDID available at input, Hot-
plug is o . An external video source
will not read any EDID in o, as long
unit is powered. When power is o ,
any input o the unit will behave like
„static“ (see below) to be DVI compli-
ant.
S STATIC: a static EDID data set is pre-
sented at the input. Hotplug signal is
always ON.
A video source is able to read
EDID/DDC data at any time.

EDID is valid!
EDID monitor name: 'CROSSBAR 8'
All data is printed in hexadecimal ormat. I available, the EDID monitor string is printed, too. The message
“EDID is valid!” says, that edid checksum is OK and EDID is valid.
Format 2: edid_read N M
Parameter:
N = [1..output count]
M = [1..8]
Reads back EDID data rom output #N and saves this data to internal bank manager bank #M, i read back
data is valid, i.e. checksum is OK.
Caution: I bank #M is already use, the new data will overwrite the old in ormation with user request.
3.6.2.5 edid_write
Format: edid_write N M
Parameter:
N = [0, 1..8]
M =[1..input count]
Copys EDID data rom bank manger’s bank #N to input #M’s EDID-EEPROM.
I bank #N (the source o copy) is empty, an error message is displayed.
I using N=0, the unit will use actory EDID as source or the copy. Using this systax will reset input #M to
actory setting.

The input EEPROM #M is overwritten immediately, independent o the EDID mode (-,S,F,T) o the input #M.
When EDID mode i “ ollow” (F), the input EEPROM is overwritten again a ter next change o routing
which concerns input #M (because ul illing the Follow-behaviour).
Pre ered application o this command is using it with inputs in „static“ (S) EDID mode. I your video source
is not sourcing video data because it does not like the “ actory” EDID in o o the input, you can read back
EDID data o a displaying device (important: that is WORKING with the source) rom the output and store it
on a bank manager’s bank available, using “edid_read” command. Then, copy the bank content to the
input where your source is attached (using “edid_write”) and then ensure, desired input is in static mode.
In doing so, your video source will get exacly the same EDID in ormation as when connected to the display
directly.
3.6.2.6 exit
Format: exit
Quits the console application. For serial console, the user is logged o . For Telnet terminal session, the ses-
sion is closed. To reconnect, you have to start a new telnet session again.
3.6.2.7 gettime
Format: gettime
Displays actual system’s clock time.
3.6.2.8 help
Format 1: help
Lists all commands available.
Format 2: help <command>
Displays additional help text or command <command>.
3.6.2.9 ifstat
Format: ifstat
Displays network connectivity status o TCP/IP network inter ace.
Example:
>ifstat
IF IP addr Def Gtway state type H/W addr
0 10.0.1.61 10.0.1.2 UP Ethernet 0 :60:35:6 :26:29
Please read it:

H/W addr MAC-Adresse o network inter ace.
ReadOnly, because used as system
identi ication.
Please use this MAC adress, i you
want to assign a static IP adress to the
unit using a DHCP server (static DHCP).
Please ask your network administrator
or more in ormation.
Table 2: Interpretation of ifstat’s parameters

3.6.2.10 ip_setadr
Format: ip_setadr DHCP IPAdr Netmask Gateway
Parameter:
DHCP = [0..1]
IPAdr = aaa.bbb.ccc.ddd
Netmask = aaa.bbb.ccc.ddd
Gateway = aaa.bbb.ccc.ddd
Sets the parameters o IP network inter ace.
Setting DHCP=1, you determine the unit to try to adress a DHCP server in your local network a ter
boot/reset. I there is a DHCP server, and it is responding, the unit will assign the network con iguration
(reported by DHCP server) to it’s network inter ace. I communication with a DHCP server ails with timout,
the network operation mode is switched to static mode and parameters IPAdr, Netmask and Gateway are
used or network con iguration.
I you have assigned a new IP Adress or the unit using your DHCP administration panel, you have to reboot
the unit to restart DHCP renegotiation.
Setting DHCP=0 you will disable DHCP and always use static IP parameters IPAdr, Netmask und Gateway or
network con iguration. In doing so, bootup time o the unit can be aster because it does not try to com-
municate with a DHCP server.
All command parameters must be entered in IPv4-dotted- ormat (decimal), i.e. 192.168.0.1. The unit is not
supporting name resolution (DNS = domain name services), so only dotted nomerical ormat is available.
For netmask, use standard orm, like or class C subnets: 255.255.255.0.
Example: ip_setadr 1 192.168.0.100 255.255.255.0 192.168.0.1
Enabled DHCP and con igures IP-adress 192.168.0.100 using a class-C subnet and IP 192.168.0.1 as gatways
to access external networks.
Remark: this example is exacly the actory setting o the unit’s network inter ace
All IP parameters are stored persistently. To make changes e ective, unit has to be rebooted. Please use
command reboot (siehe section 3.6.2.15).
3.6.2.11 Ping
Format: ping IPAdr
Parameter:
IPAdr = aaa.bbb.ccc.ddd
Send out Ping-messaged (ICMP-Messages ECHO) to IP-adress ‚IPAdr’ reports reply messages.

question that has to be answered wih ‘y’ (mind: lower case) like ‘yes’ and ENTER or command beeing exe-
cuted.
3.6.2.13 pre_load
Format 1: pre_load
Displays the usage status o all routing preset banks available (i.e. 8).
This is a typical output:
>pre_load
Preset bank status:
PRE: 1 2 3 4 5 6 7 8
STAT * - * - * * - *
OK
Row ‚PRE:’ displays the numbers o all routing preset banks available (here: one to eight)
All routing presets used read an asterisk (‚*’) the line below, all unused/ ree bank positions read as minus
sign (‘-‘).
Format 2: pre_load N
Parameter:
N = [1..8]
Recalls routing preset #N rom memory to direct execution in the switching matrix o DVI signals.
I preset bank #N is empty, there will be an error message like:
>pre_load 2
Error: bank 2 is empty
I recalling rom preset is executed sucess ully, the new switching status o the unit is displayed:
>pre_load 8
Matrix routing state:
OUT: 1 2 3 4 5 6 7 8
IN: - - - - - - 4 -
OK
3.6.2.14 pre_save
Format: pre_save N
Parameter:
N = [1..8]
Saves the actual routing state o the DVI signal to routing preset bank #N. The bank contents are persistent,
i.e. the routing is available even a ter power o and reset.
Remark: The preset stored the last be ore system power down will be used as boot con iguration a ter
power reset. This means, that i you modi y the routing AFTER the last “pre_save” command (or a similar
menu/web command), you will loose your modi ications a ter power down.

3.6.2.15 reboot
Format: reboot
Reboots the systeme immediately. Same as power o and on again.
You will loose all your telnet and web connections when rebooting your system. And you will be logged o
the serial console, but reboot messages are still displayed in serial terminal.
Remark: when rebooting, system is irst starting a so called “Bootloader”, which is intended or supporting
irmware upgrades and system management. I Booloader recognizes a “good” system con iguration, it will
continue booting the unit’s systems to normal operation. I ront panel display still showing “Bootloader”
a ter about 20 seconds, please contact your sales rep or technical support.
3.6.2.16 settime
Format: settime year month day DayOfWeek hours minutes seconds

•output #7 is connected to input #5
•output #8 is connected to input #6
•all other outputs are not connected to any inputs, i.e. do not show any video data.
Format 2: switch N M
Parameter:
N = [1..output count]
M =[-, 1..input count]
Switches output #N to input #M. I M is the minus sign (‘-‘), output N is switched o .
This command executes immediately. A ter command execution, console displays new switching state, ac-
cording to “Format 1” command result (see above).
Format 3: switch * M
Parameter:
M =[1..Anzahl Eingänge]
Switches ALL available Outputs to input #M. Same behaviour as syntax “Format 2”.

connect to the unit using the new name and password.
I entered name or password do not ull ill length and ormat reqirements, an error message is displayed.
Remark: Do use ASCII characters only and avoid any special characters in name and password. This makes
your login compatible with any terminal or Telnet application so tware.
3.6.2.19 sys_delusr
Format: sys_delusr name
Parameter:
name = (user-)name o an user existing.
Discards the user ‘name’ rom system’s user management. I user is connected to the unit while deleting it’s
record, existing connections won’t break, but the user can not open any new connections.
I user ‚name’ is unknown to the unit, an error message will appear.
Remark: Do no delete you own actual user rom user management, because you won’t be able to connect
to the unit again!
3.6.2.20 sys_fan
