i-CB General description i-CB (Communication bridge) is versatile programmable interface unit between InteliSys and Engine Control Unit (ECU) like MTU, Volvo, CAT etc. with CAN bus interface. Selected engine analog values like RPM, Oil pressure etc. and binary values like (Alarm indication) are received from ECU via i-CB. It is not necessary to install and wire external units and corresponding sensors to IS-CU. IS-CU output values like Speed governor output for synchronizing can be transmitted via i-CB (CAN) to ECU. It is not necessary to make external analog wiring. IS-CU data reading: i-CB reads selected Engine data from ECU (via CAN ECU) and transmits data to IS-CU via CAN1 bus. IS-CU data transmitting: iS-CU transmits data (e.g. Speed governor output) to i-CB (via CAN 1) and iCB transmits these data to ECU via CAN ECU. IS-CU receives data from i-CB (CAN1 messages) like from fictive IS-AIN8 and/or IS-BIN16/8 units. There are two configuration steps: • i-CB configuration (i-CBEdit), • IS-CU external inputs/outputs (fictive IS-AIN and IS-BIN) configuration (WinEdit).
i-CB configuration i-CB must be configured at first to receive/transmit required data from/to ECU. There is separate object database for each ECU that contains all available communication objects (values). i-CB configuration means object selection from the ECU database: which objects will i-CB receive from ECU and which objects will i-CB transmit to ECU. Each communication object has associated fictive IS-AIN, IS-BIN address and input or output number. i-CBEdit is PC tool for i-CB configuration. i-CB configuration is available via RS232 port. i-CBEdit contains different ECU object databases in XML format. i-CB configuration can be saved as *.icb file. iCB configuration is downloaded to i-CB via RS232. ICBEdit software for i-CB configuration is included in IG-6.0-IS-3.0 ComAp installation CD.
IS-CU configuration Corresponding fictive IS-AIN and IS-BIN inputs and outputs must be configured in IS-CU to receive and display values from i-CB (and ECU). There is possible to manage all IS-CU Alarm, display and History record possibilities. Configuration. AIS

Connect terminating 120 ohm resistors on both CAN bus ends. There are available internal – jumper selectable resistors in i-CB. To operate i-CB: 1. Configure i-CB using i-CBEdit software. i-CB configuration associates selected values (from ECU database) received from Engine Control Unit to selected CAN addresses to fictive IS-AIN, IS-BIN inputs and outputs. 2. Configure corresponding IS-CU addresses and tick in WinEdit. 3. Configure separate inputs and outputs in corresponding Analog, Binary inputs, outputs in WinEdit.

Screen above selects Input (for i-CB and IS) Analog value P-LubeOil (ECU) from ECU. This value iCB sends (after configuration) to InteliSys in CAN message like from IS-AIN8 (Address 1, Analog Input 1).
