Installation
Please use the following steps to install and set up your CMX1616A2.
When looking at the rear of the CMX1616A2, all inputs are on the left half and all outputs are on the right
half.
1. Analog audio: Connect the analog stereo audio sources to the input red/white RCA jacks marked
1-16. Connect the output cables to the output red/white RCA jacks marked 1-16. Be sure to
match the cable colors to RCA jack color.
2. Composite video: Connect the composite video sources to the input yellow RCA jacks marked 1-
8. Connect the output cables to the output yellow RCA jacks marked 1-8. Note that there are 2
different sets of yellow RCA jacks. The jacks near the TOSLINK connectors are composite
video.
3. Digital coax audio: Connect the digital audio sources to the yellow RCA jacks marked 1-16.
Connect the output cables to the output yellow RCA jacks marked 1-16.Note that there are 2
different sets of yellow RCA jacks. The jacks next to the red/white jacks are digital audio coax.
4. Digital TOSLINK audio: Connect the digital audio sources to the input TOSLINK jacks marked
1-6. Connect the output cables to the output TOSLINKS jacks marked 1-6.
5. RS-232: If needed, connect your computer or controller to the DB9 jack labeled “Control” using a
DB9 male to female normal modem cable.
6. RS-232 expansion: If using a HMX HDMI matrix, connect a DB9 male to female normal modem
cable from the RS-232 jack labeled “XP” to the RS-232 jack on the HMX matrix.
7. Connect the supplied wall transformer to a properly grounded power outlet. Plug into DC input of
the CMX1616A2.
8. Press one of the front panel buttons; you should see the LED display turn on.
Controlling the CMX1616A2
The CMX1616A2 can be controlled by 3 methods: front panel switch, infrared remote, or RS-232 serial.
You may use any or all methods in any combination. All methods can access all features and modes.
The left front panel button controls the output selection (left two LED digits). Each press will cycle
through the available outputs. The right button controls the input selection (right two LED digits). Each
press will cycle through the available inputs. Pressing and holding the left button for 3 or more seconds
will jump the output selection to the next connector type when released. Pressing and holding the right
button for 3 or more seconds is only used in Zerokey programming mode, config mode, for volume mute
toggle or for quick select mode.
NOTE: Output needs to be selected before setting the input.
Quick select can be used to easily send a single input to all outputs. To use quick select, simply select
output 1 using the left button, toggle to the input desired using the right button, and then press and hold the
right button for 3 or more seconds.
Flash modes allow the user to save and later recall up to 8 different switch setups. Flash modes are saved
to flash memory, so are unaffected by power cycling. To use the flash modes, select “Fx” (x is 1-8) using
the left button (or IR). The right LED will display “E” if no saved mode exists in this slot, otherwise “F”.
Use a short press with the right button to recall these settings. Use a long press with the right button to save
the current switch setup to this flash slot. When using IR, the sequence is (Output type select “F”, input
select 0-15). Use input select codes 0-7 to recall flash modes 1-8, and input select codes 8-15 to save to
flash modes 1-8.

The IR remote and RS-232 interface can select outputs and inputs directly. If using the RS-232 interface,
please refer to the programming guide on our web site. The IR interface is explained later in this
document.
The table below explains what the LED displays indicate. Note that generally the left two digits display the
selected output and the right two digits display the selected input. When selecting an output greater than 9,
the letter will flash for 1 second and then the “1” will be displayed. When “0” is displayed as the selected
input that output is powered off.

IR remote interface
The CMX1616A2 IR interface consists of 239 discrete IR codes. These codes are stored in internal flash
memory. When the CMX1616A2 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 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 CMX1616A2. See the section on
programming the ZeroKey interface for instructions.
The full code list can be accessed at:
http://www.video-storm.com/Downloads/IR%20mapping.htm
You can also find a tutorial at:
http://www.video-storm.com/Downloads/CMX%20IR%20programming.htm
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 analog audio output 3 to input 5 send codes 1,
then 10, then 29.
Special considerations:
1. Basic mode: All output types 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. Audio gain: The input select codes control volume instead. “0” is mute toggle and “15” is max
volume. Code “16” is Volume up (increases volume each press). Code “17” is Volume down.
There are also dedicated discrete codes for volume ramp and mute for each output.
4. Config menu: The specific output select code is not used (ignored). The input select codes work
as follows.

1 (25)
Turns LED OFF
9 (33)
Turns LED ON
2 (26)

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 first 42 IR control codes.
Before starting, you will need a remote with as many unique “keys” as codes you wish to program. Keep
in mind; most universal remotes have 5-6 “pages” of codes. For example, when you select “VCR” control
the numeric keys on the remote have different IR codes than when you select “DVD” on the remote.
Here are the steps to program the CMX1616A2 Zerokey control codes for your remote.
1. Toggle the left button until “SZ” is displayed on the left LED
2. The right LED will display a number 0-41. This corresponds to the IR code selected.
3. Toggle the right button to the IR code you wish to program
4. Press and hold the right button for 6 seconds. When released the right LED should start to flash.
5. Press the remote button you wish to map to this IR code
6. The right LED should stop flashing, indicating the code was stored.
7. The CMX may switch at this point if programming IR codes 0-7. This is normal, just toggle back
to the “SZ” mode.
8. Repeat for all other IR codes you wish to use.
9. When done, test every IR code. If one or more do not work repeat the programming for those
codes (sometimes interference will cause the code learn to fail). If you cannot get a specific code
to work after multiple attempts, try using a different remote key.
For additional examples of programming the ZeroKey IR interface, please refer to the quick start guide.
ZeroKey technology is compatible with virtually all remote controls, and does not interfere with the normal
operation of the remote. You may reset all the ZeroKey codes to the factory defaults by selecting “CFC”
and holding the input button for 6 seconds
ZeroKey programming is stored in flash memory, and you will not need to reprogram even if you lose
power. If you buy a new remote in the future, don't worry, the CMX1616A2 can be reprogrammed as
much as you like.
