- Dac/Laser (emulator or IRL)

- Redis server once.

- This server. see below.

- Load/reload webUI page from disk in a browser (webui/index.html). Javascript must be enabled.
|

- A Client, see in clients folder for examples.
|

|

|

A typical start is python main.py -L numberoflasers. Use -h to display all possible arguments.

Always start the redis server first, then laser server, maybe those two should run on the same computer, then your client.

Yes, there is a builtin DHCP client in the ether dream DAC but if you run multiple lasers, having a fixed dedicated network makes you focus on laser stuff.

About hardware setup, especially if you have several lasers : ILDA cables are insanely expensive. You may consider the Power Over Ethernet 'POE' option. Buy a very small ILDA cable, a POE splitter and connect everything to the ether dream fixed near your laser. You can have then a simple and very long network cable and use a Power Over Ethernet injector or switch closed to the driving computer. Beware some vendors use 24V POE Injector : POE injectors and splitters must match.
