6. Set up the Recorder to Change Channels on the
Set-top Box
If you have digital cable or satellite TV service, you must connect the
cable set-top box or the satellite set-top box to the Recorder so the
Recorder can change the channels on the set-top box.
Important For the Recorder to record programs received through a
cable set-top box or a satellite set-top box, the cable set-top box or the
satellite set-top box must remain turned on at all times.
The IR Control Cable and the Serial Data Control Cable
The Recorder includes two cables used to change channels on a set-
top box. Some satellite set-top boxes have a 9-pin serial input port
that is connected to the Recorder by using the serial data control cable.
Digital set-top boxes and most satellite set-top boxes are connected to
the Recorder with an IR control cable. These cables allow the Recorder
to send the same codes that the set-top box remote controls send to
change channels on the set-top boxes.
Note Many cable set-top boxes and satellite set-top boxes do not
require you to press OK or ENTER to change a channel by using the set-
top box remote control. However, some of these set-top boxes cannot
be controlled by the Recorder remote without using OK or ENTER. To
change to using OK or ENTER when changing channels, display the
Start menu and select Settings > Guide Listings > Set up TV Signal
and Guide.
Prepare for Set-top Box Setup
If you have satellite TV service, select Use a serial cable or Use an
IR cable.
Note Some satellite set-top boxes have a 9-pin serial port that does
not support input information. In this case, make sure you connect the
IR control cable instead of the serial cable. For more information, see
your satellite service hardware documentation.
Video Test
On the Video Test page, make sure a TV show is playing on the page.
If a show is playing, select Next. If a show is not playing, verify your
connections between the TV service set-top box and the Recorder.
For more information, see Connect the Recorder to the TV, Audio
Components, and Internet.
Select Remote Control Code
You must determine which set of codes the Recorder will use to change
the channels on the set-top box. The list of codes displayed onscreen are
based on the brand of set-top box you selected. Each brand of set-top
box can have multiple sets of codes. One code will be tested at a time;
if the code does not work, select another code to test.
