S3 Switch
The TSI148 VMEbus Status Register provides the VMEbus geographical address of the
MVME8100 / MVME8110. Applications not using a 5-row backplane can use these switches to
manually assign board's VMEbus geographical address. Note that this switch is wired parallel
with geographical address pins on the 5-row connector to these switches must be in the off
position when installed in a 5-row chassis in order to get the correct address from P1
connector. This switch reflects the inverted states on the geographical address signals.
Below is the switch configuration for corresponding slot address in a 21 slot chassis 3-row
backplane.
