3.1 Protocol

CAN:

CAN-Bus-protocol-PYLON-low-voltage-V1.2-20180408

or above.

RS485:

RS485-protocol-pylon-low-voltage-V3.1-20180408

or above.

3.2 Cables Connection for US2000/US3000 under RS485 or CANBUS.

3.2.1 Cables Connection for RS485

 Each battery group can configure maximum 8pcs US2000B Plus or 8pcs US3000.

 LV-Hub-A configures maximum 5 group batteries.

 RS485 communication needn’t additional cable and power just a simple hub is enough.

 When each battery group’s current is >120A, this battery group must configure 2 pair external

power cables like the diagram.

 The details of ADD Switch setting also can see the menu of battery.

3.2.2 Cables Connection for CAN (single HUB)

 Each battery group can configure maximum 8pcs US2000B Plus or 8pcs US3000.

 LV-Hub-A configures maximum 5 group batteries.
