The CCM should be installed with all of the wiring. Refer to Operations and Maintenance Manual, SEBU7014, "General Specifications for Wire and Cable" in the Operation Section of this manual.
Determine the parameters for communication for the installation. The default rate of communication (bits per second or bps) is 9600. The remaining default settings from the factory are no parity, 8 data bits, and 1 stop bit. These parameters will work well in most installations. Use the Operations and Maintenance Manual, SEBU7014, "Communication Parameters - Identify" under Service Information in this manual to determine the communication parameters that are stored in the CCM.
If the PC software for the CCM is not used, go to step 6. If the PC software for the CCM is used, refer to the "Caterpillar CCM PC For Windows: Getting Started Manual" and go to step 4.
