iM871A-USB

iM871A-USBThe iM871A-usb is a compact wireless M-Bus USB adapter based on the high performance wireless M-Bus module iM871A. The adapter offers a cost-effective RF solution for smart metering applications connecting water, heat, electricity and gas meters with standard equipment like Laptops, Tablets, etc. The iM871A-usb is qualified according to the RED 1999/5/EC and is fully compliant to the EN 13757-4 standard (S1, S1-m, S2, T1, T2,R2, C1 and C2). An adjusted output power of +14 dBm combined with the high sensitivity of the USB-Stick enables ranges up to 500m.


USB to UART Bridge Virtual COM Port (VCP) drivers for Microsoft Windows, WindowsCE and Linux are available (www.silabs.com). Furthermore the Wireless M-Bus DLL and the Wireless M-Bus Studio GUI from IMSTs Wireless M-Bus Starter Kit “SK-iM871A” can be used to easily configure and explore the iM871A-usb.
