Using Bonjour Browser to troubleshoot EUCON 3

[DanielEUCON]

EUCON 3 Bonjour Browser

There is a free tool that is very helpful when determining the source connection issues for EUCON 3.

Bonjour Browser: https://www.macupdate.com/app/mac/13388/bonjour-browser
There is a Windows version available also. Google Knows.

So here are the things to look for:

_euconproxy._tcp

- this is the service that Artist Surfaces use to connect to EuControl. In the image you can see My Artiwst Mix connected and it displays a link-local address (169.254.123.223). In this case it is set to use DHCP however it is connected via a switch so no DCHP is available. This is why you see link-local address.
- if surfaces are not connecting to EuControl this is the first place to check. If Bonjour Browser doesn’t see it, we won’t see it either and it is a network setup issue outside of EUCON world.


_eudof._tcp

- this is the big change from EUCON 2 to 3. These are the core elements that makes DAWs, Workstations and EuControl, etc talk to each other. This is not used for any Artist Surface connection but rather connecting to DAW and Workstations.
- in eudof there are various services to look for:

EUCON_MC
- EuControl on your local machine will appear as EUCON_MC.
- Any other instance of either MC App (the application that runs on MC Pro) EuControl on other machines will also appear here as EUCON_MC entries. The IP address tells you which machine it lives on.
- In the image you can see my instance of EuControl as EUCON_MC, it also has a link-local IP address (same reason as explained above).


EUCON_Node_Browser
- Any EUCON enabled Application on the network will create two instances of this. In this case I have ProTools 11 running locally only.

EUCON_Node_Observer
- this is created by MC_Client. It still runs in the background. This is needed to "see" the other EUCON nodes on the network. If this is not there you will not be able to see workstations or EUCON aware apps as EUCON nodes. In turn no EUCON connection when you focus on the app.

EUCON_Workstation
- This is also created by MC_Client in the background. This is what puts the workstation (local machine) on the network as a viable EUCON node for EuControl (or other EUCON_MC nodes) to attach to it.
- again if this is missing you will not have any app focus awareness, or EUCON connection to EUCON aware apps running on the workstation.
