The UNI-T UT181A is a logging digital multimeter with PC connectivity. See UT-D09 and UT-D07A for typical cables. Users need to enable communication in the meter's menu system before starting the application (SETUP -> Communication -> ON).
Protocol and usage
Currently there is no sigrok driver for the UT181A device. An external MIT licensed project which was written in the Rust programming language also contains a description of the protocol, see the Resources section below. This will be useful in the creation of a sigrok driver.
The choice of a serial cable and the meter's specific protocol are independent from each other. A WorkInProgress driver was used with the UT-D09 cable like this:
$ sigrok-cli --list-serial $ sigrok-cli -d uni-t-ut181a:conn=hid/cp2110/raw=/dev/hidraw0 --samples 10
