Discrete Bit Results Bits
B–19
There are 128 bits that can be set as outputs from a host device to control the
operation of the Color CVIM. These bits control:
•
Monitor display.
•
Camera trigger.
•
Toolset selection.
•
I/O forcing.
•
Selection of operation after reject.
•
Memory storage location. RAM, EEPROM, RAM Card, or external host
memory.
Refer to Tables B.2 and B.3. Table B.2 only applies to Backplane
communications. Table B.3 applies to both Backplane and Remote I/O
communications.
