3.3.1
Analog Output
The two assigned profile signals for height (Z direction) and width (X direction) can be
taken from the 4-pole connecting socket. If optional processing has been activated,
profile parameters (e.g. hight, width area etc. of a glue bead) are output on the analog
output. In conjunction with saved configurations, the scanCONTROL 28x0 measurement
system is also capable of functioning without a PC.
As deliverd the sensor supplies 400 profiles / s for 1 ms exposure time in the standard
measurement range. Other configurations can be saved.
3.3.2
Communication
3.3.2.1 FireWire (IEEE 1394)
The FireWire port is the standard link to the PC. Three equal FireWire ports with up to
400 Mbit/s are present on the controller. The high data rate enables the cascading of a
number of controllers or digital video cameras on one IEEE 1394 PC interface. In this
case both line and star-shaped connection structures can be realized which must be
connected free of loops. The controller does not supply any operating voltage to the
1394 connection sockets.
3.3.2.2 RS232/RS422
Programs can be loaded and measurements transferred via the RS232 or the RS422
interface. The RS232 connection on the controller can be connected to the COM
interface of the PC via a commercially available 9-pole extension cable (plug - socket).
Only one of these interfaces can be active. The lower data rate permits only a lower
measurement rate compared to FireWire.
3.3.3
Switching Signals
Three outputs and one input are available. All switching signals are opto-decoupled.
In the standard setting they have the following functions:
• Input "Mode": Function as for Mode button,
• Output "Error": error is serial coded, see Chap. 13.3
• Output "Mode 1" and "Mode 2": Operating mode (in binary code).
3.3.4
Synchronous and Trigger Signals
Individual profiles (scans) can be triggered or a number of sensors synchronized
together via the synchronous connection socket. Other functions are possible as
options.
3.3.5
Laser Switch-off
Pins 3 and 13 on the synchronous socket are used for the external safety switch-off of
the laser. A switching transistor with an open collector (e.g. in an optocoupler) or also
a relay contact are suitable for switching.
Laser Class 2M (IIM)
sensors: The switch-off can be configured with open or
connected pins (default setting).
Laser Class 3B (IIIB)
sensors: The laser is off if the pins are open. Therefore switch-off
is configured with open pins 3 and 13 and can not be changed.
3.3.6
Video Output
The video signal is only provided for adjustment and test purposes and can be
activated by software (see FireWire documentation).
