communication with Biosemi & acqknowledge softs

Hi everyone,

I will need to send triggers from psychtoolbox-3 to several acquisition softs to get triggers in my data. I will need to send them into physio data under acknowledge and EEG data (biosemi). Is someone already did that throught RJ45 port? It's the only port I have on my stim laptop (windows 10). Otherwise what would you advice? USB-DB25 or USB-RJ45?

thanks a lot,

Thibault.
