Console and TELNET access
3.6.1
Introduction to Console/Telnet
Console and Telnet connection to the unit is different in terms of 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) of your PC/Laptop. At the unit, please attach the serial cable to the
DSUB9-connector labeled „RS 232“ on the back side of the unit.
The serial interface 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 Microsoft Windows® operating systems or any other
terminal application programs available on you operation system preferred.
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 refer section 3.5 for adjustion network connectivity via menu buttons/front
panel or use a serial console connection (and commands listed below) to adjust network parameters corre-
cly. If your LAN is supporting DHCP, then the unit will be assigned automatically and you simply can read
the IP adress assigned with front 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
format, 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 of all, you have to authenticate to the unit, because configuration access is protected with password to
avoid unauthorised use of the unit. By default (factory 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 for console control:
•
you can add additional users using the „sys_addusr“ command (see below)
•
you can get a list of 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 forget the space in between the question mark and
the command.
•
Issueing „exit“ command will log off serial console (you have to re-login) respectively will close the
TELNET session.
