DCAM-Standard:
• IEEE 1394 is the lowest protocol level during communication.
• DCAM 1.30 is the higher protocol level, particularly for digital cameras.
• Standard digital video camera drivers according to DCAM 1.30 from various
manufacturers (e.g. Matrox) can be used.
• The scanCONTROL28x0 uses the DCAM standard, but with rededication of the
parameters:
- Camera parameters into triangulation parameters,
- Image into profile.
6.4
Output Circuit of the Error and Mode Outputs
Attributes
:
• Open collector outputs, short circuit and reverse-polarity protected up to 30 V DC,
• The resistance in the conducting state is 15 Ohm or less at IL = 100 mA.
External circuit
:
Connect load (e.g. relay) between external auxiliary power (e.g. power 24 V
DC) and the . Connect the negative pole of the auxiliary power with the negati-
ve pole of the power supply (does not apply with use of the power supply).
Remarks
:
• The connections 2, 3, 4, 5 and 9
on the "Synchron" socket are
electrically connected to the minus
pole (Power-GND) of the 24 V DC
supply voltage.
• The connections GND Sync-out,
GND RS232, GND Video, GND
Analog Signal 1 and GND Analog
Signal 2 are electrically connected to
the system ground.
• The minus pole of the supply
voltage (Power-GND) is electrically
isolated from the system ground.
