Data Link Guidelines
SMCS - 1926
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.
• 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.

i01226832
You should follow the instructions in Operations and Maintenance Manual, "Initialization for Direct Connection" before you connect by a modem. The user can verify proper operation of the CCM at the location. The user can also become familiar with the CCM.
Make sure that the following equipment is available:
• A personal computer with a terminal emulator software program. Examples of terminal emulators include Procomm, PC-VT, or Terminal under the Accessories window in Microsoft Windows. Refer to "Caterpillar CCM PC For Windows: Getting Started Manual" for specifications on the PC. The user is responsible for understanding the operation of the PC.
• The proper RS-232C cables are required for the particular installation. An RS-232C cable must be temporarily connected from the PC to the Answering Modem. Refer to Operation and Maintenance Manual, "RS-232C Cable Requirements".
• The two modems must support the Hayes AT command set. This is necessary for both the Answering Modem and the Originating Modem.
• The CCM PC For Windows software is required. This software is available from Caterpillar.
Note: Some personal computers will have an internal modem. The internal modem may be used as the Originating Modem. The internal modem must be compatible with the Answering Modem. Consult the instructions for the two modems.
Procedure
Perform the following procedure in order to initialize communication with the CCM and the Answering Modem. The Originating Modem is set up later by the PC software.
Note: In the following steps, the PC and the modems should be turned OFF before you change the cables on the serial ports. When power is reapplied, the modem must be powered up first.
1. The CCM should be installed with all of the wiring. Refer to the Operations and Maintenance Manual, "General Wiring Diagram" and "RS-232C Cable Requirements".
2. Determine the parameters for communication for the installation. The RS-232C 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 Operation and Maintenance Manual, "Communication ParametersIdentify" to determine the parameters of communication that are stored in the CCM.
Note: The RS-232C serial port communication baud rate is often referred to as the DTE speed. The phone port communication rate is often referred to as the DCE speed.
3. Connect the RS-232C port of the Answering Modem directly to the RS-232C port of the PC. This connection is temporary. This connection is required to set up the Answering Modem.
4. Use the terminal emulator on the PC to set the parameters for communication for the RS232C port. Use the same values that were chosen in step 2.
5. Several commands must be sent to the Answering Modem that set the parameters for communication to the proper values. The examples in Table 1 are Hayes AT commands. Actual command sets vary widely between modem manufacturers. Consult the manual for the modem. Save these parameters to the modem memory.
Table 1
Typical Answering Modem Setup Commands
a
Set the modem to the factory defaults. This is important if the setup of the modem is unknown. AT&F
Set to communicate in error control and in asynchronous mode.
b
c
NOTE: If the modem does not support this command, enter the AT command for error control. Set to communicate in asynchronous mode with a separate command (Item c). Otherwise go to Step d.
Set to communicate in asynchronous mode. Note: If the &Q5 command is supported, the modem is already in asynchronous mode, and this command should not be sent.
AT&Q5
AT&Q0
d
e
Set Auto answer to ON. This tells the modem to answer the phone line after the first ring. If left at 0, the modem will never answer an incoming call. The value of this register can be seen with the ATS0? command.
Set Flow Control to XON/XOFF. This turns off RTS/CTS hardware handshaking between the modem and CCM since the CCM does not have RTS or CTS lines. It turns on the XON/XOFF software handshaking.
f Set DCD to track status of carrier detect signal. This causes the DCD line from the modem to follow the state of the phone line carrier. When the call to the CCM's modem has been made and the modem to modem handshaking is done, the DCD line will change and allow the CCM to receive data.
Note: This is very important. If the DCD line is not at the right state, the CCM cannot receive data.
g Set DTR to monitor DTR signal and hang up and reset modem on an on-to-off DTR transition. This
ATS0=1
AT&K4
AT&C1
AT&D3
causes the modem to hang up and reset if the CCM drops the DTR line.
h Result codes do not have to be returned. Or, if the result codes are returned, the codes must be in originate mode, but not in answer mode.
i Set DTR transition response delay to maximum value less than 10 seconds. This example would cause the modem to hang up the line 2.5 seconds after the DTR line from the CCM changes. Note: Refer to your particular manual. Some modems specify the time in 1/100th of a second, and some in 1/10th of a second.
j Set delay before forced hang-up to maximum value less than 3 seconds.
k Write the setup parameters into memory 0. When the setup parameters are written, any that were not changed are stored into the memory.
l Set to recall memory 0 on reset.
m
View the modem active profile. This is an optional command that allows the user to view the above parameters stored in the modem. The profile should be written down and saved for future reference.

6. The setup for the Answering Modem is now complete. Disconnect the PC from the Answering Modem. Connect the PC directly to the CCM. Refer to the Operation and Maintenance Manual, "RS-232C Cable Requirements".
7. Load the CCM PC for Windows software into the PC. Refer to"Caterpillar CCM PC For Windows: Getting Started Manual". Start the CCM PC software and connect to the CCM.
8. Go to the Data Link pull-down menu. Go to the Utilities menu and select CCM configuration. Set the communication parameters to match the values that were chosen in Step 2.
9. Go to the Phone Book pull-down menu and select Add or Edit. Set the communication parameters of the PC to match the values that were chosen in Step 2.
10. The electronic engine controller of each engine must be programmed with the correct engine number to identify each ECM to the CCM. The electronic engine controller is programmed to Engine Number 1 at the factory. Refer to Operation and Maintenance Manual, "Engine Number - Program".
11. Remove power from the CCM by removing the wire that is connected to the +B terminal. Turn off the power to the Modem. Disconnect the PC from the CCM.
12. Connect the PC, the modems, and the CCM as desired for the final site installation. Refer to Operation and Maintenance Manual, "RS-232C Cable Requirements".
