    I ran in to this problem recently. My solution was to drive the DPPS with an isolated DC-DC converter (followed by an LD driver), and used a Darlington opto-isolator on the TTL drive. The entire DPPS drive is ground isolated, yet high side bonded to chassis through the laser module.

    Totally agree Dave, but it did enable us goofs to crack on whilst you electronic geniuses perfected the high side driver thingy

    Seriously, these are great little boards and will be powering my 642 diodes as soon as I can get onto it
