Re: Converting PAC2 to dumb Cresnet "landing point"

 

¿ªÔÆÌåÓý

The PAC2 had a built in Cresnet Hub (CNX-HUB equivalent) ¨C I would probably recommend getting the PAC2 out of the equation as a point of failure and replacing it with a DIN-HUB or CNX-HUB) but if you wanted or needed to keep it I am guessing you could configure the PAC2 as a Cresnet slave (assign it to an unused Cresnet ID) and still make use of the hub functionality.

?

That said as a commercial AV-not-lighting guy I think I¡¯ve physically touched 2 PAC2¡¯s in my career and loaded programming on one so¡­ YMMV

Hi Bruce,

?

I have a couple of PAC2's I'm considering the best path on as well --

?

I am convinced that those 8 Cresnet busses (A thru H) are electrically isolated from one another, and the processor routes and repeats messages from one bus to the next.? No processor, no routing.

?

The blinking LED's seem to give that away -- the more traffic destined to something on a particular bus, the brighter you see it blinking (which, if all 8 busses were joined as one, each of the LED's should blink in unison).

If I'm understanding what you are asking, you could just use a CNTBLOCK with the internal power jumper cut. That would isolate power between the two sides but still let cresnet data pass between the two sides.

I will be updating an ancient system with a PAC2 and CLX dimmers and CNX-BXX keypads to Crestron Home in a few weeks.

There's a load of the field Cresnet wires landed right on the PAC2 on its many Phoenix connectors. I'm wondering if anyone has explored a way of isolating the Y and Z connections from the internal processor so it can be repurposed as a place to land the existing wiring, and provide power as it currently does. I'm going to try and look a PAC2 to see what's inside....maybe all those connectors are on a PCB and there's just a ribbon to the processor board and I remove the ribbon? Then we'd take a Cresnet wire Y, Z, G only from the CP4R to one of the connectors.

TIA
