OK I built 50 odd DCSSR's earlier in the year , I seem to have about 12 with the same problem.
Plug into Renard no or very dim LED lights up
Jumping pin 16 on the opto to 15 13 11 and 9 all channels light
Checking pins 2 4 6 8 all 4 cycle on and off rubnning a 1 sec sequence
On the DC side checked voltage after the reg I have 5v
Cat 5 cable is a known good cable (double checked)
Pulling the opto for a known good one same result
Checked all resistor values with a multimeter all test right
thoughts ????????
