1. DAC 004 Commands Introduction The DAC 004 configuration tool allows many parameters to be configured for default use when the camera starts up This capability will accommodate most applications For those applications that are more demanding another level of programmability has been added to the DAC 004 Using a set of commands via FifeNet various parameters that are normally set statically through the configuration tool can be set dynamically under program control An example of this might be for a CDP 01 state machine program to specify a different edge count value when switching to a different guiding job Command Structure Commands are sent to the DAC 004 using the FifeNet configured parameter called DAC 004 Command Commands are all 16 bits in length with the upper 8 bits indicating the command and the lower 8 bits the associated data When a command is accepted and completed the command will be echoed back to FifeNet at the configured parameter DAC 004 Command Status An echoed value of OxFF in either the upper or lower 8 bits indicate an error in either the command or data respectively For example the DAC 004 Command Status value OxFFOO indicates an invalid command has been specified The value OxOOFF indicates the command is good but the parameter supplied in the lower 8 bits is out of range for this command 06 04 04 DAC 004 DIODE LINE CAMERA Figure Sheet 1 873 A f CONFIGURATION TOOL 1 pes 1 37 Company Acti
