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 – a device to power up and communicate with the BMS Display;
    • Also Systec, PEAK and Marathon USB-CAN adapters are supported, but external power supply for BMS Display is needed. Update routine is similar to BMS USB-CAN;
  • ElectricDeviceMonitor – a software to monitor and configure devices by Movicom Electric;
  • Firmware (*.srec) – a new firmware for the BMS Display.

Updating process

Follow the steps below:

1. Connect the BMS Display to the BMS USB-CAN.

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

  • 120 Ohm – “I”;
