Brother TC-225 / TC-229 adventure!

I have no internet access in the shop, so I went home. bringing the new firmware to the shop tonight.

I'm in no rush to break anything

alrighty, tonights update:

I found the pin to engage the relays on the relay board. you need to tie that pin to 24v GROUND. if I do that direct to the psu it engages each one, all happy like.

of course the mesa wont engage them, because its trying to output +24v on that line.

how do I go about making the mesa do this correctly? is it a setting or is it some external hardware?

thanks

Probably the easiest way would be to use a relay triggered by your Mesa card to switch to ground.

so a relay to engage a relay which in turn engages a relay....

do I also need a relay on all the 40+ inputs? seems like there should be a better way to do this.

Well a transistor is a relay by another name.

Electronics is not my forte.

But the Mesa 7i72 sounds interesting. 48 sinking outputs which is what I think you need.

Can you remind us what Mesa hardware you have, and what hardware you are trying to control?
