Once I install the tuner I would like to be able to control it remotely, from another room; Is this possible? What would be needed and how can it be done? I was browsing the manual and saw this:
"About the RS-232C Connection:
The RS-232C Connection is provided to allow the XM Reference Tuner to be controlled by
compatible 3rd party control systems. Polk Audio recommends that this connection only be
used by experienced professional system installers. DO NOT connect the RS-232C Connection
to a computer. This connection IS NOT compatible with personal computers."
Has anyone used this to remotely control the unit? How?
