Kamstrup GSM8i RF 3G Installation and User Guide

Brand: Kamstrup

Model: GSM8i RF 3G

Type: Installation and User Guide

Below you will find brief information for GSM8i 3G, GSM8i RF 3G. The GSM8i 3G is a module designed for mounting in {detected_brand} electricity meters, supporting 2G and 3G networks and provides plug-and-play installation with signal strength indication, status/pulse input, and SMS reading of meter and signal strength. The GSM8i RF 3G is an extended version with an RF Concentrator, requiring an external Triangle antenna and extra power supply. Both modules are designed to be installed in Kamstrup electricity meters. The document provides essential installation guidance, including mounting, antenna requirements, and troubleshooting.
