KERN scale series supported
We're happy to announce that libsigrok now supports various weighing scales from KERN & SOHN GmbH.
The new kern-scale driver currently supports (and was tested on) the KERN EW 6200-2NM scale and all scales from the series which have the same protocol.
The scale can report the currently measured values (both unstable and stable ones) via the RS232 cable it ships with.
The protocol is a simple (14- or 15-byte) packet-based ASCII protocol containing the measured value, the unit (gram, ounce, etc.) and an indicator of whether the measured value is stable or not.
Support for other KERN scales with a different protocol can be added easily. Please let us know if you are able to test on other devices!
Usage example:
$ sigrok-cli -d kern-ew-6200-2nm:conn=/dev/ttyUSB0 --samples 10 Mass: 26.920000 g Mass: 26.920000 g Mass: 134.600006 ct UNSTABLE Mass: 134.600006 ct UNSTABLE Mass: 134.600006 ct UNSTABLE Mass: 134.600006 ct UNSTABLE Mass: 134.600006 ct Mass: 134.600006 ct Mass: 134.600006 ct Mass: 134.600006 ct
