roboRIO manual possible confusion

[jnicho15]

On page 9 of the manual, it reads:

Note The NI roboRIO contains an internal 120 W termination resistor between L (GRN) and H (YEL).

It appears that this "W" means ohm based off of this wikipedia entry:

Where the [symbol] font is not supported, a W is displayed instead ("10 W" instead of "10 Ω", for instance). As W represents the watt, the SI unit of power, not resistance, this can lead to confusion.

Just thought this would be useful to know

Why didn't they just write out "ohm"?

...and all these years I was thinking W is for Watts - unit for power! One mre change I have to deal with this season!

FYI: W DOES NOT mean ohm, it is a font error

W still stands for watt. It showed a W in this instance because of a font error. Since the ohm symbol was not supported by the font, a W was put in its place.

just to be clear, W stands for Watt, not ohm.

jnicho15,
Can you show which manual you are looking at for this info? If it is a pdf, it is likely you do not have the greek font loaded and have selected an option where Adobe inserts what it thinks is the correct symbol.

Yep, it displays as a W.

We've got one of these on the RoboRIO!

Have you included a fan as well?

Heh - please don't dissipate 120W in roboRIO in any form.

That is a typo/font issue. I'll get a request in to fix this.

Chris,
Mike linked to a 120 watt resistor with fins on it.

Yup - pretty sure that's not included with roboRIO.

Is it against the rules to smear heat transfer paste all over the RoboRIO?

Might make robot inspection interesting.
