"$A5,<dh>,<dl>,3,'LQ',<IR Code>" (7 bytes)
Sends an IR pulse for special commands to the display. In Display Express the code can be
triggered by sending an HD channel command of 0-xxx (O-211 selects the HDMI 1 input, 0-
200 would return the TV to TV channel mode).

LQ has other uses as well; it can trigger any IR code in the library. It's similar to the KK
command in the 232-ATSC+1 manual. Refer to the code numbers on page 21 in the 232-
ATSC+1 manual. For example, sending LQ,25 will pulse a Volume Up command, and LQ,25
is Volume down. If you're using a custom control system, repeat the command as long as
the button is held down. The pulse itself will take 275ms.
Note: Not all commands are supported in different code sets, check with CR Support to
confirm operation. We will add codes as needed. Presently, the LG code set 21 includes all
the above commands.
"$A5,<dh>,<dl>,3,'N1',<Time>" (7 bytes)
Value 1-6 Sets pulse length in 100 millisecond time period. Typically, IR commands are
sent in a repeating pattern. A few TVs, such as some Visio models, will respond to every
repeat, so that channel 3-1 appears as 3311. Making the pulse shorter, typically N1,2, fixes
the problem. Sending an N1,0 command resets the controller to the default pulse length.
