Near Intersection of I-35 & I-90 Southern Mn. | Trimble and Ag Leader typically use a 120 Ohm resitor. Raven typically uses a 150 Ohm resistor.
The need for a terminator is common on all the various CAN systems that I have worked with. Sometimes this resistor is built into the wiring harness but other times it is a removable type. On systems where more devices could be added (Ag Leader etc.) the resistor is built into the dust cap or is a standalone terminator.
We've noticed that on a NORAC system, the resistor is built into the most extreme connector. Since they know that no more connections will be made past this point they can place the resistor there.
On many CAN systems, a bit of information is noted when the CAN Hi and the CAN Lo show a pulse in opposite directions. If the pulse on the CAN Hi and the CAN Lo show a pulse in the same, the information is assumed to be due to outside interference (Radio Frequency energy etc.) and the pulse is disregarded. This is part of the error detection scheme. |
