ELBOW 7D9984 - Caterpillar

The EMCP 4 has the following communication connections:
Primary CAN Data Link (CAN 1)
Accessory CAN Data Link (EMCP 4.2 only) (CAN 2)
Modbus RTU (RS-485 Half duplex)-SCADA Data Link (EMCP 4.2 only)
RS-485 SCADA Data Link (Modbus RTU, Half Duplex) (EMCP 4.2 only)Primary CAN Data Link (CAN 1)
A communications connection, utilizing CAN 1, is available on the module. The communications connection allows configuration of set points, flashing of the core software, and language text files. The configuration software has password protection for different authorization levels. Configuration of set points will also be possible using the controls on the module. Configuration of set points is made possible by utilizing the same password strategy used across the control system range.The connection will also be utilized for communicating with the engine control module (ECM) using the CAN protocol.This connection will also be utilized for communicating with automatic voltage regulators (AVR) using the CAN protocol when the AVR support this protocol. An example of an AVR is the Caterpillar Digital Voltage Regulator (CDVR).This connection also provides communications for on-package expansion thermocouple modules for use with monitoring of engine temperatures.This connection will also provide communications for the Caterpillar Clean Emissions Module System.The primary CAN communication wires are brought out of the EMCP 4 as part of the 70-pin connector.
