The Reverb posting was the only thing I could find also. It appears to be around 20 years old by the looks of it.I have searched high and low and can’t find anything on this. You got more information on the dimmer. Serial number date creates any other equipment that is VHI.
I can’t even find a company website or anything.
The only suggestion that I got is to call lightparts and see if they got any info.
I was only able to to find one setup of someone selling a VHI setup on Reverb 2 years ago.
@DMX Nubie Google "NSI IF501 Protocol converter" for a 'budget friendly', yet solid and reliable, 'many input choices to analog out' protocol converter: Pay CLOSE attention to the precise model numbers, from memory, I'm recalling two or three models with extremely similar model numbers offering a variety oF conversion options.
@Amiers Seemingly we're looking for LOGIC again? (Maybe it's four duplex receptacles = eight outputs powered via ONE line cord; thus 8 - 1 OR eight receptacles at one Kw each IF you don't try to load up more than ONE at a time.) In this case, I suspect expecting logic's only going to lead to disappointment.I'm still confused by the model 810 and what appears to be just 4 channels.
