PLUG-FELT 1363742 - Caterpillar

The communication parameters (communication rate, parity, number of data bits, and number of stop bits) are stored in non-volatile memory within the CCM. To read these communication parameters, follow these steps:1. Power down the CCM (remove the wire connected to the (+) B terminal).2. Power up the CCM [reconnect the wire to the (+) B terminal]. During the power up sequence, the CCM display undergoes a lamp test (8.8.8.), followed by the communication protocol parameters (n81 9600 E00) that have been programmed into it. These parameters can be programmed to different values. For the reprogramming procedures, refer to the Phone Book Tool section in the Caterpillar CCM PC For Windows: Getting Started Manual.
