Illustration 25 g06212239The Ethernet System
The 5-6-10XXF series pavers have an Ethernet system, separate from the CAN system. The Ethernet system serves two main purposes:
High-speed data load capability for programming the paver and screed graphical displays.
Display to grade ECM communication, for the Cat Grade Control (if equipped)The machine may have an Ethernet problem, and still function normally. The two symptoms that may indicate an Ethernet problem:
Cannot make an Ethernet direct connection to one or more of the display’s to reprogram the display software.
"ECM Disconnect" messages are appearing on the Cat Grade Control screen (if equipped).
"2D Display Disconnect" messages are appearing on the Cat Grade Control screen (if equipped).Ethernet Configuration
The Ethernet wiring is configured differently, depending on if the Cat Grade Control option is present or not. This is accomplished by installing or removing jumper plugs on the paver and screed. If Cat Grade Control is installed, the Cat Grade ECM acts as the central hub for the Ethernet. See Illustration 26. If there is no Cat Grade Control, the Ethernet is connected in a series fashion, between the display’s. See Illustration 27.Ethernet Configuration With Cat Grade Control Installed
Numbers on monitors and grade ECM correspond to the numbers shown on the electrical schematics. See Illustration 26.

Illustration 27 g06209633Troubleshooting Steps
No Ethernet connection via Cat ET
Ensure that the Ethernet connection directions are being followed as per SEHS0522.
Follow the instructions under the Cat ET “Help” tab for Ethernet direct connection.
Check the Ethernet wiring between the service port and the left paver display.
Not all 4 displays are detected with Cat ET when making an Ethernet direct connection.
Check in the Ethernet wiring between the displays as required. If no wiring problems are found, the display itself might be faulty, or Cat Grade ECM, if equipped. Ensure that wiring is good by doing continuity checks with a meter, from point to point on all Ethernet wires, before replacing displays or Cat Grade ECM.
The Ethernet service port is wired to the left paver display. If only the left paver display is detected, there might be a problem with that display, or the Ethernet wiring connecting it to the rest of the system. Check the Ethernet wiring / connections, then swap the displays side to side and see that of the problem follows.
“ECM Disconnect”, or “2D Display” message appears on Cat Grade Control screens:
This means that there is not a good Ethernet connection in between the display and the Cat Grade ECM. The Ethernet wiring will have to be verified by doing continuity checks.
There are also a few other places to look when attempting to diagnose and Ethernet connection issue on machines that are equipped with Cat Grade Control. One is the sensor connectivity screen in the Cat Grade Control diagnostic menu. (Illustration 28) This screen will also show the monitors present, along with whatever grade sensors are connected.
