Spinx1 to 7i85

An option I didn't consider is the secondary 26 pin connector on the 5i25 (P2) as it will be a messy wire termination inside the pc without some screw terminals to mount to.
Can I get the required pwm out on that connector without firmware change?

No, you still need a firmware change. At the moment the internal connector is configured for a second 7i85S with Step/Dir.

To wire neatly to that internal connector you need: store.mesanet.com/index.php?route=produc...74_79&product_id=235 or from a non-mesa source: www.amazon.com/CableWholesale-Motherboar...ds=parallel+port+idc

andypugh,

Thanks for the clarification on that. I was about to start wiring lol...

Okay, so in that case I will need a new configuration and will wire to the 7i85 as originally intended.

The 5i25 manual shows a JTAG connection for programming. Do I need to get that connector for updating the firmware???

No, you can re-program in the PC with the "mesaflash" utility.

Instructions are in the 5i25 manual, Page 12: www.mesanet.com/pdf/parallel/5i25man.pdf

Hi PCW,

I'm sorry to be a pain about this. Any updates on the firmware progress?

Thanks again for your time, your help is much appreciated.
