Variable and Flag Summary

Below is a table that summarizes the system variables and flags, sorted by type. The Flag/Variable col-
umn categorizes each as a flag or a variable. The Read/Write column indicates which can be written (W)
and which can be read (R). If the variable or flag is stored in the personality module it is marked with a
“Y” in the personality column. In addition to the system variables listed below, there are other variables
associated with IQ Cam. Refer to the IQ-Series IQ-Cam Software Manual (Part Number 0013-1053-
001)
for complete details.
