Best get in touch with Dan (@dmance). He is a great guy, honest and responsive. To be clear, Opto DX is a game changer, imo.
Regarding the best power supplies for the M-Scaler and OptoDX T, this is clearly a battery (in my case a PowerAdd PP2 with a split DC cable for powering both with 12V). I could hardly believe it, but that's what it is. On the Opto DX receiver side, a good LPS does the best job (Paul Hynes SR4).
Split DC cable. Where may I ask did you get that (and the extra tip) from?
