PXIE-1090 with PXI-4130

I have a PXIe-1090 Rack and try to use a PXI-4130 Source Unit


The PXIe-190 is visible in the MAX and with DMM everthing works fine


If i connect a PXI-4130 Source Unit, then the Rack Syszem LED turn to RED (MXI LED flashes Red).

In my opinion the Rack should work with the Source Unit.

In the NI-Configurator you can choose this two Units....


Any Idea.....


Best Regards Roland

Hi Rollo38,


Since the MXI LED is flashing red it sounds like a power problem. Looking at the specs for the PXI-4130 and the PXIe-1090 I see that the -12V rail max for the PXIe-1090 is 250mA and the PXI-4130 typically draws over 200mA. It sounds like the PXI-4130 might draw enough -12V to trip the power supply.


Do you have another chassis to test the PXI-4130 in? Or a PXIe-4130 to test with?

The NI-configurator says it work. You can choose the PXI-4130 for an PXIe-1090 Chassis
