The latest version of Sigrok available on Ubuntu 22.04 doesn’t currently support this device. So we need to build from source to be able to use it.

Here’s the steps I cobbled together to do that on my machine.

cd libsigrok

Example scanning for devices:

$ sigrok-cli -d rdtech-tc:conn=/dev/ttyACM0 --scan
The following devices were found:
rdtech-tc - RDTech TC66 1.17 [S/N: 00034756] with 6 channels: V I D+ D- E0 E1

Example showing a device:

$ sigrok-cli -d rdtech-tc:conn=/dev/ttyACM0 --show
Driver functions:
    Energy meter
Scan options:
    conn
    serialcomm
