HW-150PVR with Slingbox 500

I am looking to use the 150 to connect to my Slingbox 500. I am worried because I cannot find any information that will tell me if the Slingbox has a remove for the 150 or how I can get the Slingbox 500 to control the 150 for channel changing.
Thanks for any advice.
(I did confirm the ATVIEW does not)
