AXB Boxes, PS wiring?

vegastech

When wiring AXLink boxes, additional power supplies are often needed. In those cases, should the - on the power supply be wired in with the GND on the AXLink devices? In the case of an AXB-IRS4, I have a local power supply plugged in to the pwr (2 prong) phoenix plug, and everything other than the AXLink power plugged into the AXLink port. Do I need to run a jumper from the PS - plug to the GND plug on the IRS4?

In the case you mention, you just need to not connect the Power + wire on the AxLink buss. The two comm wires and the ground should be connected. Three wires total on the AxLink connector.

I'm pretty sure the ground on the Axlink connector and the power ground are connected internally. I have never run a jumper, just clipped off the V+ lead on the Axlink.

When we run local power on Axlink devices (often for G3 panels a long run from the rack), we only run the two data lines back to the master, and power the two power leads with a local wall wart or whatever is appropriate. No need to externally get the - and or ground power common.
