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 optional;
—
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
monitoring software;
—
4~20mA output, which can connect speed tachometer and torque indicator;
—
Through CANBUS port can read real time data of the running engine, such as speed, torque, water
temperature, oil pressure, oil temperature, total fuel consumption and instant fuel consumption etc;
—
With a reset zero button for integrated panel engine, press and hold it for more than 3s to reset
subtotal time and subtotal fuel consumption;
—
With a fault diagnosis button for integrated panel engine, press it to 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;

—
99 pieces of shutdown alarm records can be cyclically 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) V DC, which can adapt to various starting battery voltage
environments;
—
There is rubber seal ring between shell and control panel. IP65 protective level can be achieved.
