Note on Using Protocol Mode 4
An important difference between the WIT2400 and the WIT2492 is the dynamic
assignment of time slots and handles in the WIT2492. The WIT2400 required that each
remote be configured with a static address which distinguished one remote from another.
In the WIT2492, remotes are distinguished by their factory-assigned serial number. When
using protocol Mode 4 in the WIT2492, the static address of the WIT2400 is replaced
with the current handle of the WIT2492. In point-to-multipoint configurations, a remote’s
handle is not guaranteed to remain the same if the remote drops link with the base and
then re-establishes link. In a point-to-point system, the point-to-point mode of the
WIT2492 can be set to guarantee the remote handle does not change.

If protocol Mode 4 is used, the data stream being transmitted from the remotes to the base
should contain information indicating the remote sending the data as the handle assigned
to the remote can change when the link to the base is dropped and re-established.
