No
There are 2 diffrent comunication options: via a software that monitorises the ups or via 3 signals.
This cable here is for the 1) part.
For the other type,check: http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q102711& (this is quite useless,since it is very rudimentar amd the apc soft offers much more options)

I’ve got with my APC 620 a cable imprinted 940-0024c with your pin assignments, just to confirm. Checked for R of 10K, but no resistors found.

On some other sites it says that you have to add a 10k ohm resistor too..

Mr Ball (posted on 7/3/2009) is correct you should correct the db9 male side pin numbers. Other wise nice diagram!
Thanks…

Hi, you have the SmartUPS cable slightly wrong. The picture is correct, but you have counted the pins on the male connector incorrectly. The correct table should be:
Fem Male
2 2
3 1
5 9

Cheers,
