Enable Signals Configuration

The enumerated parameter FvalMode specifies the usage of the FVAL downstream signal; possible values are:

Value

Meaning

FA

The rising edge of the FVAL signal is used as a Start of Frame; the falling edge is irrelevant.

FN

The FVAL signal is ignored by the board.

FC

Raw grabbing; start/stop recording on FVAL rising/falling edges

The enumerated parameter LvalMode specifies the usage of the LVAL downstream signal; possible values are:

Value

Meaning

LA

The rising edge of the LVAL signal is used as a Start of Line; the falling edge is irrelevant.

LN

The LVAL signal is ignored by the board.

The enumerated parameter DvalMode specifies the usage of the DVAL downstream signal; possible values are:

Value

Meaning

DG

The DVAL signal is a clock qualifier,only the data transmitted during clock cycles with DVAL=1 are captured by the board.

DN

The DVAL signal is ignored by the board.

The MultiCam channel must be configured for the appropriate camera operation modes by assigning the appropriate values to the FvalMode, LvalMode, and DvalMode parameters.

Valid combinations of values for area-scan cameras (Imaging = AREA)

FvalMode

LvalMode

DvalMode

Downstream control mode

FA

LA

DN

Synchronize H/V on leading (rising) edge of LVAL/FVAL; DVAL is irrelevant.
