I'm trying to clarify the specs for the 5-volt out on the usb-8452. The 845x hardware/software manual says the module can only supply up to 20 mA. Yet, the USB-8451 has a maximum of 230 mA.
Is there a mistake in the 8452 manual or did NI cut the available current to 1/10 of the original SPI module?
I ask because we have several 8451 in our testers using the +5v out with a draw of under 100 mA. Future testers and replacements of the 8451 would mean adding another power supply to the system.
Just thought I'd better check. Thanks!

On pages 3-11 and 3-21 of this manual, compare the "+5 V Power Source" indications for both modules.
The 20mA limitation of the USB-8452 is unfortunately not a mistake.
