database
A computer file that contains all site-specific information used by a BCU to
control site operation. This file is stored in the PC Workstation and in indi-
vidual BCUs on the network. In the PC Workstation, the file is named sum-
mit.mdb and is located in C:\Program Files\Tracer Summit\Database
directory.
device ID
A software address assigned to Tracer Summit BCUs and PC Worksta-
tions when a site is first created. The device ID then becomes the

device instance, ID.
DIP switch
A dual inline package (DIP) switch is a set of individual switches pack-
