Software support for Voltcraft VC-870 multimeter used together with UNI-T UTD04 USB cable.
Target hardware: VOLTCRAFT VC-870 Multimeter UNI-T UT-D04 USB Cable The issue this software solves: Although the Voltcraft multimeter and the UNI-T USB cable are hardware compatible (the USB cable adapter fits into the multimeter connector perfectly), the software requirements are different. Original Voltcraft USB cable, which costs tripple the UNI-T cable by the way, mimics RS232 adapter when plugged in USB host PC. The UNI-T cable uses different chip internally and behaves like a HID device. On the other hand, UNI-T multimeters use different communication protocol over the serial line than VC870. This software package is composed of two independent parts: 1. USB cable interface in the utd04-cable directory, 2. multimeter protocol decoder in the vc870-decode directory. The USB cable interface is adapted from other work, see copyrights in the directory. Compile according to instructions in the utd04-cable/readme.2.txt file. The multimeter protocol decoder is a perl script. Use in a pipe together with the cable interface: ./utd04-cable/utd04-cable -b9600 | ./vc870-decode/vc870-decode.pl The above commands need to be run under root (su) because of USB access permissions required in the cable interface program.
