Guys, I really appreciate the advice given here.
So an update I took your advice and invested in a 6 way splitter(I’ll tell you which later). Bought and fitted ‘proper’ DMX cable 5pin. Hired a bunch of LED lanterns for our last production which was a success. The company now think I’m a genius, so thanks again.
Unfortunately the brand new splitter is faulty, it didn’t affect the production but I’m sending it back to the manufacturer. They have been very positive so I’ll post again once this has been resolved.
Cheers Malcolm
