You need to connect A and A1 from the associated line. Pretty simple.

Mine are exact clones of the Melco's so if you can hook up one of those, you can easily hook up one of mine. Plus they work better than the line powered stuff anyway.

Shoot me a PM, I'm not building 50 of them for just myself!

Please note: Mine do not have a casing or anything. It is just the bare PCB and a short length of cat5 cable to terminate it. There's plenty of empty space on the board to drill some holes to mount it. I mounted mine with some standoffs and some drywall screws. It's not the prettiest looking thing, but it works better than the Sandman relay I had, so I don't much care.

Chris,
Honestly, what kind of money would it take to get a solid state version of 1A2?
It really isn't all that complicated. The interrupter could be likely be replaced with a microcontroller.

Thoughts? Because honestly, I'd comfortably pay $100 to $250 for a small form factor solid state 1A2 system just to have it to play around with.

Oh, and a suggestion that might be helpful to you for revision 2:

Consider adding an 8P8C/RJ-45 jack to your PCB so it is modular.

That's exactly what I'm planning to do.

Greg Ercolano is making a solid state 1A2, but he is intentionally using discrete logic instead of microcontrollers so anyone could build it. Micro's are awesome, but only if you have the means to burn them. He could just sell the boards and a parts list and anyone could assemble one. Heck, I'd buy one if it was like a DIY kit that had the bare pcb and a bag of parts. I love soldering stuff up like that.

I'm losing my mind with how much I want one of these.

I'm holding out for the four line version.

Seriously, if he makes a four line version, that big ugly 501 is coming off my backboard.

I have been busy working in my fourth (or is it my fifth?) career, so I'm late to the party.

If you all would consider the ComKey 416 system, you will see that you are re inventing the wheel, or the KSU. The ComKey system uses electronics to replicate 1A2 electromechanical components. The "5th line" module can be used as an example, to drive one line on a key set. I have done this for demonstration purposes.
