2.1.1 Library Directories

The

SMRTSTAR

directory contains libraries required to operate the Smart Star control sys-

tem.

•

SMRTSTAR.LIB

—This library supports all the functions needed by the Smart Star sys-

tems including digital I/O cards, relay cards, D/A converter and A/D converter cards,
and serial communication.

Functions dealing with the A/D converter cards are described in this manual. Functions
relevant to the other I/O cards are described in the manual specific to the I/O card. Func-
tions dealing with the backplane and the CPU card are described in the Smart Start
(SR9000) User’s Manual.
