Symptom

The laser profiler to which you want to connect could not be discovered by Mech-Eye SDK or the GenICam client.

Possible Causes

The reason that the laser profiler could not be discovered can be any of the following, and these reasons need to be investigated one by one:

  • The laser profiler cables are not correctly connected or need to be replaced.

  • The laser profiler is connected to a router with an Ethernet cable, and the computer is connected to the Wi-Fi of the router.

  • Windows Defender Firewall or antivirus software is blocking the communication with the laser profiler.

  • Mech-Eye API or GenICam client: The laser profiler IP address and the IP address of the computer Ethernet port connected to the laser profiler are not in the same subnet.

  • The IP addresses of multiple computer Ethernet ports are in the same subnet.

Solutions

The instructions for actions on the computer in this section are only applicable to the Windows operating system. If you are using the Ubuntu operating system, please contact Technical Support.

Please investigate each of the above reasons one by one according to the following sections.

Cables Incorrectly Connected or Need to Be Replaced

Please follow these steps to troubleshoot the issue:

  1. Check if the laser profiler cables are worn, broken, or damaged otherwise.

    • If the laser profiler cables are damaged, contact Technical Support to acquire a replacement. Then, check if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

      • If so, the troubleshooting is completed.

      • If not, proceed to step 2.

    • If the cables are not damaged, proceed to step 2.

  2. Refer to Laser Profiler Hardware User Manual and check if the laser profiler cables are correctly connected, without issues such as not fully tightened connector nut or tangling with other cables.

    • If the laser profiler cables are not correctly connected, please correct the connection, and then check if the laser profiler can be found in Mech-Eye SDK or the GenICam client.

      • If so, the troubleshooting is completed.

      • If not, proceed to the next section.

    • If the laser profiler cables are correctly connected, proceed to the next section.

Computer Connected to Router Wi-Fi

Please follow these steps to troubleshoot the issue:

  1. Open the Control Panel and select View network status and tasks under Network and Internet.

  2. Check if Wi-Fi is displayed next to Connections.

    • If so, proceed to step 3.

    • If not, proceed to the next section.

  3. Disable the Wi-Fi function of the router or connect the router and computer with an Ethernet cable. Then, check if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

    • If so, the troubleshooting is completed.

    • If not, proceed to the next section.

Communication Blocked

Please follow these steps to troubleshoot the issue:

  1. Open the Control Panel, and select System and Security  Windows Defender Firewall.

  2. Select Turn Windows Defender Firewall on or off on the left, and then check the selected options.

    • If the selected options are Turn on Windows Defender Firewall, select Turn off Windows Defender Firewall instead. Then, check if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

      • If so, the troubleshooting is completed.

      • If not, proceed to step 3.

    • If the selected options are Turn off Windows Defender Firewall, proceed to step 3.

  3. Turn off the antivirus software installed on the computer or change its blocking settings to allow the communication of Mech-Eye Viewer or the GenICam client. Then, check if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

    • If so, the troubleshooting is completed.

    • If not, proceed to the next section.

Laser Profiler IP address and IP Address of Computer Ethernet Port Not in the Same Subnet

This section is only applicable to Mech-Eye API or the GenICam client.

Please follow these steps to troubleshoot the issue:

  1. Check the laser profiler IP address in Mech-Eye Viewer.

  2. Refer to Set IP Address on Computer and check the IP address of the computer Ethernet port connected to the laser profiler.

    • If the computer Ethernet port is set to Obtain an IP address automatically, refer to Set IP Address on Computer and set a static IP address for the Ethernet port. Then, proceed to step 3.

    • If the two IP addresses are not in the same subnet, modify the IP address of the laser profiler or the computer Ethernet port so that the two are in the same subnet. Then, proceed to step 3.

      Modify the laser profiler IP address

      Use Mech-Eye Viewer or the IP configuration tool to modify.

      Modify the IP address of the computer Ethernet port

      Refer to Set IP Address on Computer.

    • If the two IP addresses are in the same subnet, proceed to the next section.

  3. Check if the laser profiler can be discovered by Mech-Eye API or the GenICam client.

    • If so, the troubleshooting is completed.

    • If not, proceed to the next section.

IP Addresses of Multiple Computer Ethernet Ports in the Same Subnet

Please follow these steps to troubleshoot the issue:

  1. Disable the Ethernet ports other than the one connected to the laser profiler:

    1. Open the Control Panel and select View network status and tasks under Network and Internet.

    2. Select Change adapter settings on the left. The Network Connections window will pop up.

    3. In the Network Connections window, right-click the Ethernet ports other than the one connected to the laser profiler and select Disable.

  2. Check if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

    • If so, then the IP addresses of multiple computer Ethernet ports are in the same subnet. Proceed to step 3.

    • If not proceed to step 4.

  3. Modify the IP addresses of the disabled Ethernet ports and then enable these Ethernet ports:

    1. Return to the Network Connections window, and refer to Set IP Address on Computer and modify the IP addresses of the disabled Ethernet ports to other subnets.

    2. Right-click these Ethernet ports and select Enable to enable these Ethernet ports. Then, check again if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

      • If so, the troubleshooting is completed.

      • If not proceed to step 4.

  4. Restart the laser profiler: Disconnect the laser profiler from power and then reconnect it to power. Then, check again if the laser profiler can be discovered by Mech-Eye SDK or the GenICam client.

    • If so, the troubleshooting is completed.

    • If not, please contact Technical Support.
