Firmware update

Introduction

The document describes the steps to update the BMS Display firmware.

Required hardware and software:

  • PC or laptop with Windows 10 or newer;
  • BMS USB-CAN adapter – a device to power and communicate with the BMS Display;
  • ElectricDeviceMonitor – a software to monitor and configure devices by Movicom Electric;
  • Firmware (*.srec) – a new firmware for the BMS Logic 12/18.

Updating process

Follow the steps below:

1. Connect the BMS Logic 12 or 18 to the BMS USB-RS485 with harnesses:

  • X1 header of the BMS Logic device – to the side (“Cells”) header of the BMS USB-RS485;
  • X4 header of the BMS Logic device – to the upper header of the BMS USB-RS485.

2. Move switches of the BMS USB-RS485 to the following positions:

  • 120 Ohm – “I”;
  • Cells – “0”;
  • +5V – “0”.

3. Connect the BMS USB-RS485 to a PC.

4. Move the switches “Cells” and “+5V” of the BMS USB-RS485 to “I”. Check that the led “DS1” of the BMS Logic 12/18 is blinking.

5. Open the Device Manager* and determine a name of an appeared serial port (Click the right mouse button on the Start menu and select the “Device Manager” item):

9. Click the “Browse…” button and open the new firmware file.

10. Boot the device to go into the bootloader mode.

10a. For the BMS Logic 12 v3.3 and older or BMS Logic 18 v3.2 and older (which have an address switch onboard):

  • Move all switches to the OFF state so the address is 0. The device will show that it is in the bootloader mode by flashing the DS1 with 0.5Hz frequency.

10b. For the BMS Logic 12 v3.4 and newer or BMS Logic 18 v3.3 and newer do the following steps:

  • In the ElectricDeviceMonitor, select the menu “Tasks – Monitor - BMS Logic 12/18 3.x”:

  • Set the following connection settings and click the “Launch” button:
    • serial port name of the BMS USB-RS485
    • baud rate and data format: 115200 kbps, 8 bits, no parity, 1 stop bit
    • address – 247

  • Select the menu “Monitor - Stop” or click the “Stop” button to release the serial port and allow to use it for updating the firmware.

11. Return to the “Updater” window and click the “Update” button. The updating process will start.

12. Wait the updating process is finished. Move the switches “+5V” and “Cells” to the “0” position and disconnect the BMS Logic device from the BMS USB-RS485.
