2
3 To connect the BMS Logic 12 to a PC, use the BMS USB-RS485 adapter. It allows to power and communicate with the BMS Logic 12:
4
5 1. Connect the BMS USB-RS485 to the BMS Logic 12:
6 a) the communication circuits (X3 -> X3);
7 b) the circuits of cells (X5 -> X1).
8 1. Connect the BMS USB-RS485 to a PC using a mini-USB or USB-C cable.
9 1. Turn all the BMS USB-RS485’s switches to the “I” position.
10
11 The assembly drawings of the harnesses between the BMS USB-RS485 and BMS Logic 12 are give below.

57
58 Set the following settings to connect to the BMS Logic 12:
59
60 * 115200 bps,
61 * 8 bits,
62 * no parity,
63 * 1 stop bit,
64 * device address 247.
65
66 The address 247 is a service address that the device will always answer.
