NUT SELF LOCKING 8T5065 - Caterpillar

The CCM has the ability to communicate with a maximum of eight other controllers. The number of available connections will depend on the type of device that is being connected. Generator set applications are limited to eight controllers that can be connected to the CCM. Marine applications are limited to a maximum of three connections. The CCM identifies different controllers on the data link by the Module Identifier (MID) of the controller. The MID is programmable in some cases. Refer to the Operations and Maintenance Manual, "Engine Number - Program" for more detailed information on programming the Module Identifiers. Each controller that is connected to the CCM must have a unique MID.There are two versions of Electronic Control Modules (ECM) for 3500B EUI Engines. The connection to the CCM will depend on the version of the ECM. The version of the ECM is based on the serial number of the engine. The serial number is listed on the engine nameplate. Use the following chart to determine the correct version of controller for each engine.

Version C of the ADEM II controller (ECM) has a primary data link for use with the CCM. This data link is called the CAT Data Link. The Module Identifier (MID) of this controller is a fixed value. Each controller on the CAT Data Link must have a unique MID. The CCM can only be connected to one Version C ECM on the CAT Data Link.
Version D of the ADEM II controller (ECM) also has a primary data link for use with the CCM. The value of the MID for the primary data link is fixed. Version D also has a secondary data link for use with the CCM. The Secondary CAT Data Link has a programmable MID. A maximum of eight different values is available for generator set applications. A maximum of three different values is available for marine applications.
