OBJECTS
The following is a list of predefined or “fixed” objects that reside in the BACstat II products, which you
cannot create or delete. When connected to an MS/TP network, these objects are readily accessible over
the network. When connected to a LINKnet network, many of these objects are mapped into matching AI
or AV objects residing in the Application Controller above.

* Names are user settable (to a maximum of 8 characters), and only on outputs when they are controlled remotely (i.e., MUXed).
These are the typical objects that may be commanded on-the-fly by a user or from GCL, and would also include the Outputs
(AV1-3) when they are MUXed. Never command the Configuration Variables (AV12, AV21-13) on-the-fly. Refer to page 34.
