Connect
Connect the modem cable to the PC (the host) and the mobile device (the client). Select “Connect” from the Start Menu on the
mobile device (Start > Programs > Communications > Connect).
Note: Run “Connect” when the “Get Connected” wizard on the host PC is checking COM ports to establish a connection for
the first time.
Note: USB synchronization will start automatically when the cable is connected, not requiring you to select “Connect” from
the Start menu.

Cold Boot and Loss of Host Re-connection
ActiveSync assigns a partnership between a client and a host computer. A partnership is defined by two objects – a unique
computer name and a random number generated when the partnership is first created. An ActiveSync partnership between a
unique client can be established to two hosts.
When the mobile device is cold booted, the random number is deleted – and the partnership with the last one of the two hosts is
also deleted. The host retains the random numbers and unique names of all devices having a partnership with it. Two clients
cannot have a partnership with the same host if they have the same name. (Control Panel > System > Device Name)
If the cold booted mobile device tries to reestablish the partnership with the same host PC, a new random number is generated
for the mobile device and ActiveSync will insist the unique name of the mobile device be changed. If the mobile device is
associated with a second host, changing the name will destroy that partnership as well. This can cause some confusion when
re-establishing partnerships with hosts.
