====== SCPI Scripts on Linux Mint ======

Here I will describe a simple solution to control two units of programmable power supplies via Ethernet. 

===== Setup =====
  * 2 Units, Rigol DP832 with Ethernet (LXI) Extension installed
  * Notebook running Linux Mint 17.3

===== Ethernet Config =====
First the Ethernet interface on the RIGOLs has to be configured. We have to use fixed IP-addresses so our scripts then will work every time we want to use them.

===== Configure Nemo on Linux Mint =====
The goal is to have shell scripts, which can be run with a double-click. \\

For this Nemo's config has to be changed, so we don't get annoying dialogs: \\

===== The Scripts =====
For the shell scripts we use netcat (short nc), which makes a raw TCP connection to the SCPI-Server (the RIGOL instrument). Netcat gets the SCPI command via echo and a pipe. \\

To make a script runnabla/clickable, we have to give it the permission via right-click, Properties:
