You initialized and connected the RSx scanner to the USB-to-Ethernet adapter, but not to the integrated Local Area Network (LAN) port in your computer. The LAN port does not detect the scanner, but the port works fine when you connect other devices or networks to it.
A possible cause is that the Network Interface Card (NIC) speed setting is set too high (for example, 1 Gbps). If the setting is set at too high a bandwidth, communication with the Arm fails.
If you set the Speed & Duplex property to Auto Negotiation, the NIC detects the best speed for communication with the arm.
To do this:
From Windows, click Start.
Type Network Connections.
Click the Control Panel option View network connections. You should see a screen with all the enabled and disabled network connections.
Right-click Local Area Connection.
Select Properties from the pop-up menu to display the Local Area Connection Properties dialog box.
Click the Configure button.
Select the Advanced tab.
From the Property section, select Speed & Duplex.
In the Value section, select Auto Negotiation if not already selected.
Click the OK button to save your changes.
Your LAN network settings should now allow communication with the ROMER Arm.
You can find the original "ROMER Arm Unable to Connect to LAN Port" article at this Hexagon Knowledgebase site.
