Reply to Connecting DJM to Yamaha HS5s?

my very simple question needs a very simple answer.. one that appears to be no-where on the internet..

AM I RIGHT in believeing that the cables I need to connect my DJM 400 mixer to my Yamaha HS5 active monitors is simply an RCA to XLR cable?

this looks obvious enough, but when I took to the web for confirmation, a lot of people seem to have a lot of different answers..

This should be all I need.. Confirm or Deny.

(only using one XLR per monitor obvs.)
