How does the Interwrite Board connect to the computer?
The Interwrite Board connects to the computer via a serial, USB or wireless Bluetooth connection.

Why are there different colored pens for the Interwrite Board when you can choose the pen color from the Interwrite software menu?
There are different colored pens for two reasons: 1) You can set the software to auto-detect a pen change so that it will recognize the pen you are holding. 2) In dry-erase modes, the pen color indicates how the computer or printer recognizes that pen. In other words, if you have a red Expo dry-erase marker in a blue electronic pen, the computer et printer will recognize it as blue.

What is Enumeration?
Enumeration happens when a Plug-N-Play device is plugged in or is unplugged. This signals Windows to load or unload a driver for the corresponding device. If a driver has not been loaded or can’t be found, Windows will ask for the driver.

Why do I get warnings about the lack of a digital signature when I install the TDK device driver on my system?
Microsoft encourages hardware manufacturers to submit their drivers for testing with Windows. If Microsoft deems a driver is acceptable, it provides a digital signature that the manufacturer can include in his driver. Windows checks for the digital signature in a device driver et deals with it, based on the setting in the Control Panel/Systems/Hardware/Driver Signing option. You have the option of ignoring the presence or absence of a digital signature, being warned if a digital signature is absent from the driver you are trying to install, or blocking the installation of an unsigned driver. According to Microsoft, the default setting is Warn. The system will warn the user that the device driver being installed is not signed et give the user the option of going ahead with the installation, or canceling it.

The TDK Bluetooth device drivers are not signed. In addition, they set up a number of virtual COM ports on which the driver is installed. So, when the Driver Signing option is set to Warn, a warning will appear for the real COM port et for each virtual COM port the driver sets up.

You can remedy this situation either by accepting each warning et electing to install the driver, or by going into Control Panel/Systems/Hardware/Driver Signing et clicking on the Ignore radio button.
