No. Function Cable Size Remark
16 RS485B 0.5mm
2
Shielded twisted-pair cable is recommended to use,
single end is grounded.
External 120Ω resistor is not required, whether using
internal 120Ω match resistor can be determined by
“Match Resistor Enable” item.
17 RS485A 0.5mm
2
18 AI3_RIU 1.0mm 2
Analog input port,
resistance/current/voltage
type can be configured.
Setting items see Table
10.
19 AI4_R 1.0mm 2
Resistance type analog
input port.
20 DI5_HL 1.0mm 2
Aux. output port, high/low
electric level active can be
configured.
Setting items see Table
10.
21 DI6_HL 1.0mm 2
22 DI7_HL 1.0mm 2
23 DI8_HL 1.0mm 2
24 CAN_L 0.5mm
2
Shielded twisted-pair cable is recommended to use,
single end is grounded.
There is 120Ω match resistor between CAN_L and
CAN_H inside controller.
25 CAN_H 0.5mm
2
26 AI5_R 1.0mm 2 Resistance type analog
input port.
Setting items see Table
10.
27 AI6_R 1.0mm 2
28 GND 1.0mm 2 Analog input port COM.
29 +5V OUT 1.0mm 2 Output DC+5V.
30 GND 1.0mm
2
Analog input port COM.
31 B- 1.0mm
2
Connects starting battery negative.
32 D+ 1.0mm 2
Connects charger D+ (WL) terminal, it hangs in the air if
there is no this terminal on the charger.
33 B+ 1.0mm 2
Connects starting battery positive.
Warning! When DO_COM_H port active COM is connected to
external power supply, power reverse connection is prohibited,
otherwise controller will damage.
34 DO_COM_H 1.0mm 2
Output port active COM, connects starting battery
positive.
Warning! Power reverse connection is prohibited for
DO_COM_H port, otherwise controller will damage.
NOTE1: The back USB port is for parameter programming, PC can be used to program controller;
NOTE2: HEM4300 controller can suit for DC (8~35)V battery voltage environment, battery negative must be reliably
connected to engine shell. The sectional area from power B+ and B- to positive and negative connection line is not less
than 1.0mm

. If floating charger is installed, please direct connect its output line to battery positive and negative, then
separately connect battery positive and negative to controller input port of positive and negative power, preventing
charger disturbing controller’s normal running.
NOTE3: All outputs of controller are transistor active outputs. If need expand relay, please add freewheel diode (when
expand relay coil has DC) or RC circuit (when expand relay coil has AC) to coil two terminals of expand relay, preventing
it disturbing controller or other equipment.
