# Power Measurement – Scientific Wordprocessing for MacOSX

> The HM8115-2 is a programmable 8kW Power-Meter supplied by HAMEG Instruments.

## Article

This adaptor comes with a config program that allows to set the IP-Address and serial parameters. Unfortunately the WIZnet config tool is available for Windows only. We use VirtualBox to virtualize a WinXP instance under MacOSX and set the parameters as follows.
We open a TCP socket to 192.168.1.9 (configured IP-Address) and port 5000 and send the ASCII command *IDN? followed by <CR>. The device replies with HAMEG HM8115-2!
All that is left to do now is to somehow mount the WIZnet board plus a power supply into the HAMEG case. We turn around the serial interface and solder three wires to the SUB-D pads 2, 3 and 5.
