Here's the initial email I got back from PRS with the pertinant info on the switching:
Hi Vaughn,
Pin 1 is a +4.5VDC supply (used for the LEDs only).
Pin 2 connects to the channel switch relay.
Pin 3 is no connection.
Pin 4 is the -4.5VDC supply for the relays.
Pin 5 connects to the loop relay.
The pin numbers I have given are not the order of the pins from left to right, they are the pins as numbered on the jack. See link for reference -->

In using an aftermarket switcher box, it is critical that the +4.5VDC and the -4.5VDC not be connected as this will cause damage to the amplifier that is not covered under warranty.

Found this on the original thread about it. With the information provided, it seems that what they
MIGHT be doing is taking the old school latch type for like an old Marshal or an old Orange, etc. and running both the the channel switch and loop switch in one connector. (A connector is a connector, a cable is a cable, it just depends on what you do with it.) Which brings up two possibilities, get a 5 pin din cable, like a midi cable, cut one end off, put some other ends on it and get something like the Voodoo Lab Controller Switch, or see if you can get you amp modified with just two quarter inch jacks to control those, like basically every other two channel amp ever made...
Midi sends actual data down the line (i.e. device 1 got to channel 16.1 (it's confusing I know but just know it's a small amout of data)). Old school ones are just basically a pedal switch and when you press it in it completes the circuit and that changes the thing you are trying to change (i.e. sending it to channel 2 or 3, turning on the effects loop, etc.) I'm thinking that this is what the Archon is doing, just with one cable and one connector. (This is what I was saying is pretty crappy, here buy a $2000 dollar amp and be limited on how you use it.
And before some one starts complaining about price, they had to design a special switch to use it this way, which probably cost more than just designing it in the "normal" way in the first place.
I say this because it looks like the way the pin out is is:
1. 4.5v for the LEDs on the switch
2. Channel switching
3. not used
4. Common ground (I know it says -4.5v, but that should be just a ground.)
5. Loop switching.
If you put 2 or 5 to 4 it I think it would send it switch the amp for you. And if you put 1 to 4 with no load in between you're going to over load the ground circuit and damage the amp.
