User cannot turn “Grade On” with iGrade 2.

Symptoms:

You have iGrade setup for remote Control. You have a field design in T3RRA Cutta with your zero set and you are on the design surface in the field. You select the “Grade Off” button to turn “Grade On” with no luck. 

You have checked T3RRA Cutta to make sure you are sending commands to iGrade and it is.

Under the Status tab near the “Grade Off'' button you will see the “Status: Disabled” and “Last Exit Code: No Surface Defined”.

 

Cause:

iGrade is not receiving messages from T3RRA Cutta, therefore “No Surface Defined” will be displayed and iGrade will not let the user turn “Grade On”

Solution:

Check the serial connection from T3RRA Cutta to iGrade. Use the Diagnostics built into iGrade to ensure serial communications are being received. You should see the “Line Count” steadily counting up.

 

Check that the iGrade harness is not faulty, or has pins backed out
