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 1T-MX-4355 is a 5x5 VGA Matrix Switcher capable of switching video and
audio (plus YPbPr, Composite Video or S-Video with cable adapters),
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.
Insure that there is adequate ventilation and make sure that there is access to
the rear and front panels.
Ensure that the 1T-MX-4355 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 adapter to a working AC outlet and then to the 1T-
MX-4355. 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.
Turn the input and destination equipment on and then turn on the 1T-MX-4355
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 1T-MX-4355 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 1T-MX-4355 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 adapter is
plugged in to both the unit and the AC socket and that appropriate AC voltage is
available at the socket.
5.1 Control via the Front Panel Switches
There are five input and five 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 1T-
MX-4355. 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”

8
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.)
Here are some operational tips that will allow you to use the 1T-MX-4355 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 5
inputs and 5 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. Finally, 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.
•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

9
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 1T-MX-4355.
Note: The front panel buttons will not light up when using the IR remote to control
the unit.
5.3 Direct Control via RS-232 Option
Using appropriate control codes, it is 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.
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.

6.0 TROUBLESHOOTING
Aside from faulty AC or DC power, most problems with the 1T-MX-6344 relate to
damaged/poor quality cables or incorrect signal levels.
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.
After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions before contacting TV One. Should the dealer’s
technical personnel be unable to assist you, contact TV One 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.
