Cascading function:

BM200 - * * C/D has cascading function. Multiple BM200 running at cascading can

simultaneously apply for more than 125 series battery pack connected in series. Which is

high-voltage and large capacity. for inspection and maintenance.

Here show you how to use cascading function:

Select a BM200 - * * C/D device with #01 RS485 address can running as a host. Actually

the default RS485 address of all BM200 - * * C/D device are #01.

All other BM200 - * * C/D devices participating in the cascade must be designated as

slave mode, and the 485 addresses of the devices must be changed to "# 02", "# 03"

and "#nn", according to the connection order of the battery pack. The 485 address can

be modified via [3. Set System Param] on the initial page. Press the <Up> key briefly,

and the address will be+1. Press the <Enter> key briefly, and the current modified

address will be confirmed to take effect. Press <Enter> 2 seconds return to main page.

Connect each BM200 equipment participating in the cascade with the 485 connection

cable; Each BM200 is connected with its own number of positive and negative battery

poles. The following figure shows an example of 8 BM200-05C/D cascades

After cascading, only # 01 host has the power to set battery parameters and control

functions. The control of slave is prohibited. The host will send the same battery setting

parameters to each slave, and start/ stop function operations synchronously. The display

screen of each slave will display the voltage, current, capacity, internal resistance, SOC,

SOH and other information of the corresponding battery unit.

It is recommended that the host use APP (for phone, PAD or PC) to set and control the

operation in the cascading state, because in this way, you can fully understand the

details of each battery cell on the mobile phone or tablet.
