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.
- EMCP II (basic model) has a primary data link for use with the CCM. This data link is called the CAT Data Link. The CAT Data Link has a programmable MID. A maximum of eight different values may be used for the MID.
- EMCP II+ has the same primary data link as EMCP II (CAT Data Link) with a programmable value for the MID. The EMCP II+ also has a secondary data link for use with the CCM. The CCM Data Link has a programmable value for the MID. The CAT Data Link and the CCM Data Link have eight MID values.
- The Secondary CAT Data Link and the CCM Data Link can be treated in the same manner on the 3500B Version D and the EMCP II+ applications.
- There is a maximum of one CCM per data link.
- There is a maximum of one CCM per engine.
The previous descriptions govern the connections between the devices and the CCM. When an ADEM II controller and an EMCP II or EMCP II+ controller are connected, the CAT Data Link is always used for the connections. All subsequent connections to the CCM (ADEM II Version D or EMCP II+) are made by using the secondary data link. The following examples will illustrate some valid CCM connections with multiple electronic controllers. These examples are only a representation of most possible valid connections or combinations.
