IR remote interface
The Colorado IR interface consists of 42 discrete IR codes. These codes are stored in internal flash
memory. When the Colorado detects a transmitted IR code, which matches one or more of the codes in
memory, it performs the action dictated by that code. The table below shows what action each code
performs. The factory defaults for all 42 codes can be obtained in CCF format from our web site. If you
have a fully programmable remote, you can load these codes into the remote. If your remote does not
support loading hex IR codes, then you will need to program new codes into the Colorado. See the section
on programming the ZeroKey interface for instructions.

8-23
24-41
The sequence for switching an output requires sending 3 IR codes. First send the code to select the output
type (code 0-7), then the code to select the specific output (code 8-23), then the code to select the input
(code 24 – 40). For example (in advanced mode), to switch component video output 3 to input 5 send
codes 0, then 10, then 29.
Special considerations:
1.
Basic mode: All output types except HDMI are selected with output type code 0.
2.
Set ZeroKey mode cannot be accessed by IR or RS-232. This must be done by front panel buttons
if necessary (one time only).
3.
Config menu: The specific output select code is not used (ignored). The input select codes work
as follows.

All other codes should not be used when in config menu
Programming the ZeroKey remote interface
The remote control interface can use ZeroKey infrared code cloning to map any remote control key to each
of the 42 IR control codes. Depending on how you are using Colorado, you may not need to program every
IR code. For example, if you are using Colorado without HDMI, you only need to program IR codes 0, 3,
4, 8-24, and 24-40 (36 total codes).
Selects the output type "U" (component video)
Selects the output type "C" (coax digital audio)
Selects the output type "O" (TOSLINK audio)
Selects the output type "H" (HDMI)
Selects the output type "CF" (config menu)
Specific output select 1-16. The output selected is the (IR code – 7)
Input select 0-16. The input selected is the (IR code – 24)
