7.5.1.4 Modifying the serial port number in
Windows
The Windows OS allows for mapping of the serial
ports. Regardless of the hardware configuration, each
serial port can be assigned a COM number from 1 to
256.
When installing on Windows environment, the OS will
automatically assign a port number which may not
necessarily meet the needs of the user.
To change the serial port number:
• Connect and install the DCZ keyboard.
• Go to the settings in Control Panel/System/
Hardware/ Device Manager.
• Scroll the list of peripherals and select Ports (COM
and LPT). The USB CDC serial port emulation
(COMx) port corresponds to the DCZ keyboard.
• Click on Property for the required port.
• Go to Port settings/Advanced and change the
port number in COM port number. Some ports
may indicate they are in use by other devices,
though this is not usually the case. If you select
a port in use, check whether other devices (for
instance an analog modem) are already using it.
• Press Confirm and exit.
After changing the port number, the Device
Manager tab may still indicate the old COM number.
Close the Device Manager tab and then re-open it
again to see if the number has been changed.

7.5 Installation in Virtual Com
Port mode
7.5.1 Installation on PC with Windows
environment
Installation consists of three phases:
• Retrieval of the configuration file
• Keyboard connection and recognition
• Change of the serial port number.
7.5.1.1 Online retrieval of the configuration
file
Download the driver at:
www.videotec.com/dcz.
7.5.1.2 Retrieval of the unsigned
configuration file from keyboard
Some Windows® versions do not request a signed
driver (Windows® XP, Windows® Vista, Windows®
2000). You can download the driver from the
keyboard.
Press and hold the
ESC key and connect the
keyboard to the PC.
This will allow the keyboard to be recognised as a
MSD device on start-up. The OS recognizes it using
system drivers.
In Computer resources search for the relative device
(defined as Removable disk).
The device contains two files:
• xp_vista.inf for Windows Xp and Vista Operating
Systems;
• win2000.inf for Windows 2000 OS.
Copy the file required by the installed OS to the PC.
Disconnect the keyboard.
7.5.1.3 Keyboard connection and
recognition
Connect the keyboard without pressing any keys. The
OS wizard procedure will ask for the driver. Enter the
path to where the configuration file has been saved.
Follow the wizard instructions to complete the
operation.
