6.8 Telnet Control
Before attempting to use the Telnet control, ensure that both the Scaler (via the LAN
port) and the PC/Laptop or control system being used are connected to the same active
network.
To access the Telnet control in Windows 7, click on the 'Start' menu and type 'cmd' into
the Search eld then press Enter (see below for reference). Under Windows XP, go to the
'Start' menu and click on 'Run', type 'cmd' then press Enter.
Under Mac OS X, go to the le menu then navigate to
Go→Applications→Utilities→Terminal (see below for reference).
Once in the command line interface (CLI) type 'telnet' along with the IP address of the unit
you wish to control (see below for reference).
This will bring us into the device which we wish to control.
Note: The IP address can be obtained from the OSD menu under Information. If the IP
is changed then the IP Address required for Telnet access will also needs to be change
accordingly.

14
Type '?' to list all the available commands (see below for reference).
Note: All commands will not be executed unless followed by a carriage return. Commands
are case-insensitive.

15
6.9 WebGUI Control
On a PC/Laptop that is connected to same active network as the Scaler, open a web
browser and type device's IP address on the web address entry bar. The browser will bring
up the control page of the Scaler (see below for reference).
Note: The IP address can be obtained from the OSD menu under Information. If the IP
is changed then the IP Address required for Telnet access will also needs to be changed
accordingly.
