GREX and Printer Ports or MOD BUS

[mhdale]

Hello all, this machine I am currently building is being controlled by a GREX. My question is, is it possible to use a GREX AND the native printer ports for I/O? or would i have to go to something like the MODBUS? I am still pretty green at this stuff and find the amount of Info I have to sort through is overwhelming and sometimes foriegn to me. It is possible that I can make everything work with just the GREX I/O but in the event that i Need more I/O what is the simplest way to go?

Thanks,
 Mike

At this point the you can either choose g-rex OR the printer port, not both. If you do run out of i/o the best solution is mod-bus.

Gotcha! I have ordered one of the MODIO from Homan designs in the event I need more I/O... its just another thing to learn.... and I only Just started to get the hang of the Printer Port stuff.... Now GREX AND MODBUS.... My head is going to explode!
