WhereLAN-III MAC addresses now ends in either 2, 6, A, and E. This new
MAC scheme allows more efficient use of the MAC space defined for this
product and easy recognition by users and the system in identify a unit as a
WhereLan-III or II by just looking at its MAC.
However the embedded tags still follow the format of the WhereLAN-
II, meaning they MATCH bits 31 down to 2 of the unit’s MAC address
in order of RF Tag thru wired time ports.
Older versions of the WhereWand FW assume that the lower 32-bits
MATCH between the MAC and the RF tag-ID. To fit WhereLan-III
into the MAC space it is now that sensors MATCH bits 31 down to 2.
The embedded tags not matching the MAC address is causing issues,
because the WhereWAND uses the Rf embedded tag id to
communicate with the Location sensor.
The differences described above cause three main issues with the WhereLAN-
III MAC address and running an older version of VSS prior to VSS 4.0.5.2,
cause.
1. The Blink Service auto-generates a list of expected/known system
embedded tags based on the MAC address in SiteData. Entering the
MAC as listed on the unit, a legacy BlinkService will not generate a
proper list of embedded reference tags, and the Time Service will not
receive the embedded tag blinks it needs from the WhereLAN-III.
2. iSensor validates the MAC addresses in sitedata.dat match the MAC of
the Location sensors. With legacy iSensor, this causes red-lights on
the health and status display.
3. The WhereWAND’s download of the site configuration contain the
MAC addresses of each Location Sensor. The WhereWAND must use
the Rf embedded tag Id to communicate with the location sensor and
legacy WhereWand FW calculates the tag-ID incorrectly, resulting in
no-response from the specific sensor.
