CHRocodile CLS integrated on measurement system:
In addition to the Power supply and Ethernet connector used for stand-alone device, the CHRocodile
CLS need to be connected to other interfaces to be integrated into complex measurement
configuration systems. The other possible interfaces are described hereafter:
-
The USB port (Serial interface RS232),
-
The Sub-D15 female connector (Trigger Input/Output and Serial interface RS422),
-
And the Sub-D26 male connector (Encoder-input),
Encoder-input
The incremental encoder-input makes it possible to precisely assign each measurement points along
the line and axis positions without additional hardware. The CHRocodile CLS can manage with 5-axis
Encoders.
For an exact distance or thickness measurement it is necessary for every measurement value to be
assigned to the exactly correct spatial coordinates. This data must be recorded in the system and
transferred to the evaluation processing unit over the internal interface. To accomplish this, the sensor
is equipped with an encoder-interface.
Default are the encoder inputs not terminated.
Tye Sw0t02 to GND to terminate with 100 Ohm channel 0 to 2
Tye Sw3t04 to GND to terminate with 100 Ohm channel 3 to 4
If the encoder-signals are fed through the sensor and additional other devices are connected (e.g. for
axis control), the 100 Ohm termination can also be deactivated. Since the device has to be opened to
do this, you should contact Precitec Optronik before beginning any work of this kind.
Trigger Input/Output
The trigger options make the lighting cycle externally controllable and the synchronization between
e.g. a scanning system and the CHRocodile CLS measurement rate. This means that external
triggering is possible for every measurement up to the full measurement rate of 2000Hz.
The interface contains the connection points for the synchronization and RS422 serial communication.
Serial interface RS232 and RS422
The serial RS232 and RS422 are interfaced on respectively the USB port and the Sub-D15 female
connector. Serial communication are mostly used for configuring the sensor by sending command as a
hyper-terminal. As the number of channel is high with a huge amount of data, serial communication
port cannot support data transfer.
