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.
ActiveSync with a Cradle
To ActiveSync, the cradle must be powered off, the ActiveSync cradle cable attached to the
desktop PC and the cradle, then the cradle connected to external AC/DC power.
Note: ActiveSync transfers files to the MX3X (only) over the RS-232 connector on the cradle
using the MX3X070CBLD9RS232AS cable.
