2.6.3 USB port RS232 serial communication
The serial RS232 is interfaced on the USB port. Serial communication are mostly used for 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.
2.6.4 Ethernet connector
The CHRocodile CLS has a RJ45 standard connector for Ethernet communication.
Connect the isolated RJ45 standard connector from the CHRocodile CLS unit to an Ethernet network
(PC). Ethernet is the only port which can support the data transfer. Ethernet is also used for setting
configuration through commands (Cf. command SODX in section 5.2), for loading Calibration Table
(Cf. command TABL in section 5.2). Use shielded Ethernet cable for the data port connection.
Ethernet communication allows to transmit 6 data at 2KHz. If more than 6 data are requested, it is
possible to use Jumbo Packet configuration. In that case, you need to check network hardware for
Jumbo Packet support and use the IPCN command to configure the Jumbo Packet size. Disconnect
the sensor and configure the PC network hardware for the identical size and reconnect the sensor.
2.6.5 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 120 Ohm channel 0 to 2
Tye Sw3t04 to GND to terminate with 120 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 120 Ohm termination can also be deactivated.
