4.0 CONNECTING THE HARDWARE
Please study the panel drawings below and become familiar with the signal inputs,
outputs, power requirements plus any controls present.
The MX-6388 is an 8x8 HDMI Matrix Switcher capable of switching HDMI signals
including 3D, 12 bit deep color signals with HDCP encryption. Also provided is EDID
capability for most monitors, including a learn mode feature.
To begin to configure the system, mount the unit with the supplied rack mounting
hardware or place the unit on a flat surface that offers security and accessibility. Ensure
that there is adequate ventilation and make sure that there is access to the rear and front
panels.
Ensure that the MX-6388 power switch is in the “Off” position and turn off any equipment
that will be part of the installed system. Next, connect the input and output cables as
required. When you plug in the cables, connect them securely and relieve the strain on
the cables as much as possible so that they will not become unplugged.
Next connect the supplied AC cable to the MX-6388 and then to a working AC outlet. If
you are using the RS-232 control function, connect the RS-232 cable at this time. If you
are instead using the Ethernet functionality, connect the Ethernet cable at this time. Note:
You cannot use both RS-232 AND Ethernet. You must choose one or the other.

6
Turn the input and destination equipment on and then turn on the MX-6388 Matrix
Switcher.
Note: To realize the full bandwidth capability of the switcher, you must use the highest
quality cables available. Using poor quality cables or cables that are damaged will
degrade the performance of the switcher and may result in an absence of signals
entirely.
5.0 OPERATING THE UNIT
The MX-6388 is a special type of device called a Matrix Routing Switcher. A Matrix
Switcher allows any input to be routed to any (or all) outputs whereas a regular routing
switcher only allows the operator to select an input that will be sent to one dedicated
output.
The MX-6388 can be controlled via any of four (4) methods: From the front panel, by use
of the included Infrared Remote Controller, via Ethernet or via the RS-232 functionality.
(See sections 5.2, 5.3 and 5.4 for IR, RS-232 and Ethernet control.)
If you have not done so already, press the Power Switch and observe that the Power
“On” LED illuminates. If it does not, make certain that the AC socket is providing the
appropriate AC voltage and the AC cable is securely plugged in at both ends.
5.1 Control via the Switches
There are eight input and eight output selectors, a “Mute” button, a “Take” button, A
“Clear” button, a “Lock” button and a button labeled “All”.
Using these buttons, you can control all switching actions possible with the MX-6388.
These actions are described below:
To select one input and one output, select the input first and then the output. Both
buttons will light up, and when you press the “Take” button, the selected path will be
completed from the input to the output.
To cause one input to appear on multiple outputs, select the input followed by the
outputs (press each one separately –not all at once). Each button pressed will light
up to indicate that it has been selected. When the “Take” button is pressed the
selected paths will be completed from the input to all designated outputs. (Note that
the “All” button can be selected if you desire the source to appear on all outputs.)

7
The MX-6388 has EDID support that should be suitable for most needs. Each input
has two DIP switches that are used to configure the EDID capability for the individual
input(s).

audio for system check.
4 Bypass means the matrix will use the EDID learned from activating Learning
Mode. Note that this could cause compatibility issues with some displays. If
you cannot get audio and/or video output, please change the DIP switch
setting to default mode or even safe mode and verify the functionality of the
device.

Here’s an enlarged view of the rear panel showing one of the EDID DIP switches. Each of
the eight EDID selections operate in the same manner as described above.
Operational Tips
Here are some operational tips that will allow you to use the MX-6388 most efficiently:
When a source or output is selected, the current live configuration will be lighted to
allow the user to know what paths are active. Example: When selecting a new path
for source 1, you’ll see what outputs already have source 1 active. When selecting
output 1, you’ll see what source is already active on that output. This will help prevent
you from making changes to paths that are critical.
There is a function called “Group Selection” which allows you to split the 8 inputs
and 8 outputs into combinations of single and multiple paths. For example, you could
select source 1 and destination (output) 2, then source 2 and destinations 3 and 4.
Next, you could select source 3 and set its output path to destination 5. After making
these selections, you would press the “Take” button and complete all the paths at
once as three distinct groups. Note that until you press the “Take” button, you can
revise your selections as required if you’ve made a mistake or the mission has
changed.
The function of each of the remaining buttons is as follows:
The “Clear” button resets all selections made between the time you begin the
process and when you press the “Take” button. All lighted buttons will go dark when
you press the “Clear” button to indicate that you’ve changed you mind. You can then
begin again with new selections.
The “Mute” button functions as a “no signal” source which can be routed to an
individual or multiple outputs. Select the “Mute” button followed by the outputs you
wish to blank out followed by the “Take” button. (Note that there will be no sync
signal present on a muted output, so the connected display may go to sleep or enter
power save mode.)
The “Take” button causes the actual switch to be made and will remain lighted until
all the selected paths have switched.

9
The “Lock” button will freeze/un-freeze the operation of the front panel and disable
the front panel buttons (Note that RS-232/Ethernet commands will still function
normally).
Note: Deselecting outputs when a source is going to more than one output is
accomplished by selecting the source (which will then indicate the current output
destinations), and then pressing the already active outputs you wish to de-select
followed by pressing the “Take” button. This action will “mute” the selected output(s) but
still maintain the source path to any other destinations you had previously selected. (You
can accomplish the same thing by using the mute function as described above.)
5.2 Control via the Infrared Controller
The included Infrared Remote Controller has three sections of selector buttons that can
be used to control the MX-6388.
Note: The front panel buttons will not light up when using the IR remote to control the
unit.
Normal matrix functions are performed by pressing
the numbered button of the input you wish to route
from the two rows of “INPUT” buttons followed by
pressing the numbered button(s) of the desired
output(s) from the two rows of “OUTPUT” buttons.
After selecting your preferred input and output(s)
you must press the “TAKE” button on the remote to
make the switch take place.
Pressing any of the numbered “SOURCE SEL.”
buttons will result in that input being sent to ALL
outputs after you press “TAKE”.
If the “TAKE” button is not pressed within 5
seconds of your initial input selection then all un-
taken remote selections will be cleared.

10
5.3 Control via RS-232 Option
Using appropriate control codes, it’s possible to switch any input to any output under
control of a computer or other hardware control device. To use this functionality, first
prepare a control cable by reference to the table below. Make certain that you have
continuity between the pins as shown.

menus located in the Input and Output Selection Areas to the left and right.
To directly send an input to an output, open up the drop down menu to the right
of the Output and select the Input to route to it. The connection line will move to
indicate the new route.
To route an Input to more than one Output, select the Outputs you wish to affect
in the Output Selection Area on the right (each button will turn grey to indicate it is
selected). After you have selected all of the Outputs you wish to affect, select the
Input you wish to send to those Outputs from the buttons in the Input Selection
Area on the left. The connection lines will move to indicate the new routes.

15
EDID Learning Function:
The EDID learning function is only necessary whenever you encounter any display on the
HDMI output port that cannot play audio and video properly. Because the HDMI source
devices and displays may have various levels of capability in playing audio and video, the
general principle is that the source device will output the lowest standards in audio
format and video resolutions to be commonly acceptable among all HDMI displays. In this
case, a 720p stereo HDMI signal output would be probably the safest choice.
Nevertheless, the user can force the matrix to learn the EDID of the lowest capable HDMI
display among others to make sure all displays are capable to play the HDMI signals
normally by performing the procedures stated below.
1. Identify the number of the “Output” that is connected to the monitor you wish to clone the
EDID from. Press and hold the associated “Output” button until the light blinks rapidly and
then stops. Once the blinking stops you can release the “Output” button. Next, select each of
the “Input” buttons that you wish to assign the selected monitor’s EDID to. After selecting all
of the desired inputs, and having verified that their LEDs are lit, you can press the “Take”
button to begin the cloning process. The selected LEDs will turn off one by one as the EDID is
cloned to each input. Once the process is completely finished all of the “Input” LEDs will have
turned off. This process can take more than a minute if all 8 inputs were selected.
2. To return an input to using the default internal EDID, press and hold the “All” button until the
LED blinks rapidly and then stops. Once the blinking stops you can follow the procedure
outlined above and the EDID of the selected inputs will return to using the internal default.

6.0 TROUBLESHOOTING
Aside from faulty AC or DC power, most problems with the MX-6388 relate to
damaged/poor quality cables, incorrect signal levels or EDID incapability.
If some inputs function correctly and others do not, interchange cables between sources
and see if the problem moves with the cables. If it moves, a bad cable or cable connector
is the probable reason for the trouble. If the problem remains with one particular input,
connect that source to a different input using the same cable and see if the problem
moves. If it does, the problem is with the source.
Note: It is strongly recommended that you use premium cables in order to achieve
maximum distance cable runs and the best performance possible.
As a final step before contacting technical support, use the Web GUI to perform a system
reset will return the unit to the default settings. After trying the above suggestions should
the problem still persist, contact your dealer for additional suggestions before contacting
tvONE. Should the dealer’s technical personnel be unable to assist you, contact tvONE
via our support website: http://tvone.crmdesk.com. Create a technical support request
on the site and our support team will respond within a short period of time.
