With my display being both sides of a driveway, I was thinking that a DMX splitter might be the way to go. Could someone enlighten me to the pros and cons? I did a search on ACL, there doesn’t appear to be many recent posts but a fair bid back from 2012 where there was a fair bit of friendly banter about opto-isolation / no isolation, short leads and positioning of the splitter etc. Can anyone suggest a two-way RJ45 splitter? I noticed that David_AVD mentioned one that he had built (APC756) My other option might be build one? I searched online and found a few circuits (see one attached) I have a heap of SN75176 IC’s, I could give the circuit shown below a go, looks simple enough to make with a bit of Veroboard.
