Another fun new feature is the built-in IR input port.
One of the things I appreciated immediately is the flexibility of the port. This port can be used with a 5V IR sensor OR a direct connect to an IR blaster!
I was able to control the Pro just by connecting the IR blaster output from my TV into the Pro. The IR pass-through feature of my TV worked great! Similarly, any IR blaster from a home IR network, slingbox, or PC control should work beautifully. No messing with touchy IR LEDs.
The proper cable for direct connection is easily made by any competent HT installer, using the port pinout on the back of the Pro.
If I preferred, I could control the Pro by using an IR sensor instead. Put the Pro in a closed or hidden cabinet with the sensor near the TV, and you would be gold.A note about the two IR ports
The IR ports on the Pro and the OWLink DLI are not the same. Our DVR Pro tour guide from DIRECTV explained it very well:
The OWLink receiver [the DLI] uses negative logic (-5V) and expects an unmodulated signal.
The Pro IR Input was designed to be more general by allowing a modulated signal to be used. The positive 5V output is important to commonly-used external gear looking for a positive voltage indicator.
[Thus]... the ports are not electrically compatible as they serve similar purposes but differing applications.
I tested both ports in their intended manner, they work great. (And I had a lot of fun working with them, but then again I'm an EE geek in a CS sheepskin.)
All in all, the Pro has extremely flexible arrangements for control when you consider all the IR ports, the RS232 port, USB, RF, IR, and DLI possibilities.
