Frequently Asked Questions
Q: What is the difference between ECM31-B08 and B09?
A: The B08 includes WiFi 2.4GHz + Bluetooth 4.2 for short-range wireless LAN and mobile commissioning. The B09 replaces this with a 4G LTE cellular module for wide-area remote connectivity — ideal when no local network infrastructure is available.
Q: Can I run Node-RED on the ECM31-B08 out of the box?
A: Yes. Node-RED comes pre-installed on Ubuntu. Connect via browser on the same network, open the Node-RED editor, and start building data flows immediately — no additional software installation required.
Q: What industrial protocols does the ECM31-B08 support?
A: The device supports Modbus RTU/TCP (via RS485/Ethernet), CAN 2.0A/B, and standard TCP/IP. MQTT and HTTP are supported at the application layer through Node-RED nodes, enabling direct cloud integration with AWS IoT, Azure IoT Hub, and similar platforms.
Q: Is the ECM31-B08 suitable for outdoor or harsh environments?
A: Yes. The PCB is triple-proof conformal coated (anti-mold, moisture-proof, salt-spray resistant) and the device operates across -40℃ to +85℃. It is designed for industrial enclosures, DIN rail mounting in control cabinets, and similar demanding deployments.
Q: What power supply does the ECM31-B08 require?
A: The ECM31-B08 accepts a wide-range DC input of 9–36V, compatible with standard 12V and 24V industrial power rails. No additional power converter is needed in most panel installations.
