Note for Australian installations only:
Installations of the 9508 terminal with an 1151 PSU and BM12 must be restricted to the same building as the host
Gateway. That is, the 9508 – if installed with an 1151 PSU and BM12 – cannot be connected in a campus environment
where the 9508 terminal is installed in a building separate from the building housing the Gateway. This application cannot
be used with exposed (out-of-building) wiring.
For installations in which the 9508 is used without the 1151 PSU and BM12, campus connections are acceptable: the 9508
can be located in a separate building in these cases.
This restriction applies to Australian installations only.
