Headers

The BMS Display has three headers for connecting the BMS (P3, P4 и P5), a header for an external button (P6) and a switch which connects a terminal resistor to the CAN bus (SWD1).

P3, P4 and P5 – headers for communication with BMS

Receptacle Housing: Molex 430250400. Terminals: Molex 43030

Pin	Name	Description
1	CANH	CAN H line for communication with the BMS controller
2	CANL	CAN L line for communication with the BMS controller
3	+5V	Supply voltage 5V
4	GND	Ground

P6 – header for external button

Receptacle Housing: Molex 430250200. Terminals: Molex 43030

Pin	Name	Description
1	BTN1	Button line (dry contact)
2	BTN2	Button line (dry contact)

SWD1 - CAN terminal resistor switch

To connect the terminal resistor between the CANH and CANL lines, switch the SWD1 to the ON position.
