Hello,

It's been ages since I've been in this neck of the interweb!    I'm looking for any possible information on a SoundLogic S-Spindle Speed-R3 Rev4 board.  I'm pretty sure it's a James Cullins design.  I've never had the pleasure of messing with what I'm assuming is a Modbus/serial setup, so any info would be helpful and appreciated. 

Thanks,
Scott
