The Ir Control Cable And The Serial Data Control Cable - LG LRM-519 User Manual

The IR Control Cable and the Serial Data Control Cable

If you have digital cable TV service or satellite TV service, you must
use the IR control cable or the serial data control cable to connect the
Recorder to the digital cable set-top box or the satellite receiver set-
top box. When you change the channels by using the remote or when
the Recorder must change the channel to record a show you have
scheduled, the IR control cable or the serial data control cable sends a
code to the set-top box to change the channel.
The IR control cable works with any set-top box that has a remote
control. Plug the mini-jack on the cable into the Recorder, and then
place the other end of the cable in front of the remote control receiver
(or sensor) on the front of the set-top box.
The serial data control cable can only be connected to a satellite set-top
box with a 9-pin serial input port. The mini-plug on the cable connects
to the Recorder.

Notes
• The serial data control cable provides the best connection between the
Recorder and a satellite set-top box. However, only a few satellite set-top
boxes have a serial input port. If your satellite set-top box does not have this
serial input port, you must use the IR control cable.
• During the on-screen setup process, the Recorder will ask you to select the
brand and a manufacturer code for the digital cable or satellite set-top
box to which your recorder is connected. Selecting the right brand and
manufacturer code will allow the recorder to change channels on the cable
or satellite set-top box using the IR control cable or serial control cable.
• Some satellite set-top boxes—including some DirecTV set-top boxes with
Home Control or non-standard serial connections—require an additional
cable to connect the Recorder to the satellite set-top box. To determine if
your satellite set-top box requires this cable or to purchase the cable, contact
your satellite set-top box retailer or the satellite service provider.
• Do not connect both the IR control cable and the serial data control cable to
the satellite set-top box at the same time.
• Before you connect the serial data control cable, make sure the power cord
for the Recorder and the power cord for the satellite set-top box are not
plugged into a power outlet or power strip.
