HEM8400 Engine CAN Monitoring Controller is an intelligent instrument and controlling device that combined microelectronic technique, electric measurement technique, digital-analog hybrid signal processing technique, CAN communication technique, vehicle controlling technique and engine electronic control technique. It is the ideal product for engineering vehicles’ CAN communication and electric device control with its high integration and powerful CAN gateway functions (can replace Murphy display totally). 
 
PERFORMANCE AND CHARACTERISTICS
With 32-bit ARM microprocessor as the core, 4.3-inch LCD display, touch buttons operation and English/Chinese language can be selected;
Two CANBUS ports, one is connecting with engine ECU, and the other one is standby;
RS485 communication port enables data communication via ModBus protocol through PC software;
Through CANBUS port can read real time data of engine, such as speed, water temperature, oil pressure, oil temperature, total fuel consumption and instant fuel consumption;
With a reset zero button for integrated panel engine, press and hold it for more than 3s to reset subtotal time and fuel consumption; 
With a fault diagnosis button for integrated panel engine, press it enter into diagnostic mode, if ECU alarms occur in this mode, users can check corresponding fault alarm information through flicker times of engine red light, and press it again to exit diagnostic mode;
Hand throttle switch: push button on the panel, press it after engine start to activate hand throttle, which can accurately control engine speed;
With J1939 international standard 9-pin engine diagnostic port;
Users can change parameters settings, and changed parameters will be memorized into internal FLASH storage simultaneously to avoid losing data if power down; 
Real-time calendar, RTC, and running time accumulation functions;
Diesel engine total start times display;
99 pieces of shutdown alarm records can be cyclic stored and records can be checked on the site;
Use hard screen acrylic material to protect screen with strong wear-resistance and scratch resistance;
Rubber panel and buttons with strong performance to work in high/low temperature;
Widely power supply range (10-35) VDC, which can adapt to various starting battery voltage environments;  
There is rubber seal ring between shell and control panel. IP65 protective performance can achieve.
