Just lost a stack of dimmer packs. Opened them up: No isolation at all.
So, I'm going to build Kristof Nys' isoltor/booster, but there's no isolation on the outputs. I'll be adding that.
The question is: He's got the output grounds all tied together. I see that is a current path.
As DMX is balanced, is there any real reason I should connect Pin1?

Wrong group... sorry!
Yup ;-)
I just bought some ISO485P's (isolated RS-485 drivers) and DCP010505BP's (small 5vdc-5vdc isolated power supplies) on eBay. The ISO485P is a 14-pin device with the middle 10 pins unused. So an 8-pin 75176-type device can be accommodated on the PCB under its footprint using the same 14-pin socket for either device family (either/or, of course).
