Issues retriving CAN data from Caterpillar 287C
I have been working on a project where I have to retrieve CAN data from a caterpillar skid.
I have been sucesful in connecting the pcan to the linux computer and through a software made by my department in college I was able to see human readable information from a truck (J1939) and also from a ECU simulator (J1939). The problem comes when I connect it to the skid, nothing shows up on the software. When I connect the caterpillar to the PCAN-VIEW on my windows laptop it retrieves CAN messages but since they are not human readable they are not usful to me.
Caterpillar has a different J1939 pinout but I think I have figuered it out since I have gotten CAN messages on the PCAN-VIEW. However there has to be an issue that I am not seeing in my set up.
I am setting it up in the following way: 3 pins connection on the DEUTCH 9 (CAT), Grd, CAN-, and CAN+. which are pins B, F, and G respectively. From there female pins to an ethernet cable (CAT5e) and it ends on a serial port where CAN- is on pin 2, GRD on 3 and CAN+ on 7. After that tehre is a 120ohm terminator resistor, a gender changer and then the PCAN-USB adaptor.
Do you guys think that terminating the other end of the cable would make any difference? I have only used one terminator on the truck and also on the simulator.
Any advice, suggestion, or expereience that you can share with me will be much appreciated.
