ActiveSync is a Microsoft program which allows a Windows PC to connect to Windows Toradex modules. It can be downloaded for free from Microsoft. ActiveSync doesn't work on Windows 7 and later. There is a successor of ActiveSync called Mobile Device Center which works on Windows 7 and later and is able to connect to a Windows CE device.
An ActiveSync connection is usually made through a regular USB cable (PC=host, Colibri=client), but can also be established through a serial port.
The ActiveSync connection can be disabled through the Windows CE control panel:
Start -> Settings -> Control Panel -> PC Connection Uncheck "Allow connection with desktop computer when device is attached".
Instead of using the control panel, the same setting can be configured directly in the registry:
[HKEY_CURRENT_USER\ControlPanel\Comm] AutoCnct=dword:1 ;default(1)= allow Autoconnect. 0=do not connect over ActiveSync
The Toradex module's USB client port will still be seen as a virtual serial port on the PC, if ActiveSync is installed. To communicate over this virtual serial port, an application is required on both ends - the PC and the Colibri.
On Windows Embedded Compact 7, if explorer shell is disabled, ActiveSync won't run. We provide a workaround for this:
The CAB file is only there for users to test it. If users want ActiveSync without Explorer shell, they should integrate the source code into their software.
