1.1 Power off
The Status LEDs are off when the power supply cable is not connected:
- Check the power cable.
1.2 Communication error:
No possible Ethernet communication between CHRocodile C and your computer:
- Check the Ethernet cable is plugged correctly in RJ45 sensor unit connector.
- Check the IP configuration for your PC and the CHRocodile C unit (Cf. $IPCN command in
Appendix 1).
- If you are using a switch, then try to connect directly from your LAN network to the sensor unit.
- If possible, a Peer-to-Peer connection is recommended.
No possible serial communication between CHRocodile C and your computer:
- Check the multipoint cable is plugged correctly in multipoint connector (9 pins),
- Check the baud rate is correct.
1.3 Distance Measurement:
The target is positioned in front of the sensor, and no distance measurement is collected for all
channels.
- Set the measuring frequency to minimum ($SHZ100).
- Set the LED intensity to maximum ($LAI100).
- Check if a white light spot is emitted from the optical probe and if it is focused on the target.
- Check if the target is inside the measuring range of optical probe (Cf. section 2.8).
