1.3 Getting the Best Results
There are many factors affecting the quality of results when switching HDMI type
signals. Some basic precautions will ensure the best possible performance from your
1T-SX-632 or 1T-SX-634 HDMI Switcher.
•Output display device – The quality of the output signal will depend largely upon
the type and quality of the HDMI display device used. For instance, some video
projectors just look better than others.
•Distance between the switcher, the sources and the display – This plays a
major role in the final result. Long distances are possible, but special measures
should be taken in order to avoid cable losses. These include using high quality
cables. Line amplifiers may also be necessary for the longest runs.
•Input/Output connection cables – Low quality cables are susceptible to
interference. They degrade signal quality due to poor matching and can cause
elevated noise levels. Cables should be of the best quality.
•Interference from nearby electrical devices – These can have an adverse effect
on signal quality. For example, an older computer monitor often emits very high
electromagnetic fields that can interfere with the performance of video equipment in
its proximity.

4.0 CONNECTING THE HARDWARE
Connect the HDMI Video Sources to the inputs of the 1T-SX-632 or 1T-SX-634 HDMI
switcher, connect its output to a HDMI Compliant monitor and lastly connect the AC to
DC Power Adapter. The drawings below show the locations of the inputs, output, power
switch and power connector.

4.1 Connecting the Inputs to the 1T-SX-632 or 1T-SX-634
You can connect any HDMI compliant device’s output to any of the HDMI inputs. Make
certain that the HDMI cable is securely plugged into the source device as well as the
HDMI Switcher. Always use a high quality cable, as short a length as possible, for best
results.
4.2 Connecting the 1T-SX-632 or 1T-SX-634 Output
Using a high quality HDMI cable, connect the output of the HDMI Switcher to an HDMI
compliant display device. Use the shortest cable run possible.
4.3 Connecting Power to the 1T-SX-632 or 1T-SX-634
Both units are shipped with a Power Adapter to convert 100~240VAC@50-60Hz to
5VDC. Connect the DC Output Cable from the Power Adapter to the back of the unit
and then plug the Power Adapter into an AC Receptacle. You will be able to turn the
HDMI Switchers “On” via either the front panel power switch, the power switch on the
Infrared remote control or via RS-232 commands.
4.4 Using the Positive Cable Securing Feature
If HDMI cables are used that are equipped with Locking type connectors, an added step
is necessary. Remove the Philips head screws from the rear of the unit just above the
HDMI connectors and replace them with the Hex Nut/Screws that came in the 1T-SX-
632 or 1T-SX-634 accessory pack. After screwing these into the threaded holes vacated
by the Philips head screws, the Hex Nut provides a threaded receptacle for the screw
that is part of the locking HDMI connector on the cable. Plug in the cable’s Locking
HDMI connector and secure it to the unit with its integral screw. This fastens the cable
to the unit and prevents its inadvertent removal.
4.5 Optional Rack Mount Kit
The 1T-SX-632 and 1T-SX 634 HDMI Switchers can be mounted in a standard 19”
equipment rack. To mount the units, the optional RM-230 Rack Mount kit must be
purchased. Using this kit, either type HDMI switcher can be mounted in the rack. It is
also possible to mount one of each switcher in the rack using the dual rack mount
capability. It is not necessary to mount two of the same type of switchers.

5.0 OPERATING the HDMI SWITCHERS
The 1T-SX-632 and 1T-SX-624 HDMI Switchers can be operated via the front panel
controls. If the cable run length is excessive and the quality of the display is less than
optimum, you can press the Enhance switch on the front panel which will turn on a low
noise amplifier within the switcher and light an LED indicating that the amplifier is in use.
Provided there is enough signal for the amplifier to recover the HDMI bitstream, you will
be able to use inputs and a display located farther apart than is normally possible.
Another front panel control is the input select switch. This switch is pressed to select the
desired input. Each time the switch is pressed, the next input in sequence (from left to
right) is selected. LED displays indicate which input is active. Finally, there is an On/Off
Power Switch and an indicator LED that shows when the unit is turned on.
5.1 Operation of the 1T-SX-632 or 1T-SX-634 via Remote Control
5.2 Operation of the 1T-SX-632 or 1T-SX-634 via RS-232 Machine Control
Operation using RS-232 protocols is possible for either HDMI Switcher. The technical
information needed is provided in the two charts which follow but if you are not
technically inclined, seek help from an appropriately trained individual since cables will
have to be constructed and programs written to use the RS-232 capabilities.
5.2.1 RS-232 Commands
Command Action
“I” + “1” Port 1 On
“I” + “2” Port 2 On
“I” + “3” Port 3 On
“I” + “4” Port 4 On
“S” + “1” Enable Signal Enhance
“S” + “0” Disable Signal Enhance
“P” + “1” Power On
“P” + “0” Power Off
Operation of the HDMI Switchers is possible via an included
Infrared Remote Control. Selection of Enhance mode is not
possible from the IR Remote however the unit can be turned on
and off and the inputs can be selected simply by pressing the
appropriate button on the remote. Note: When you unpack either
HDMI Switcher, you may have to remove an insulator from the
battery compartment of the remote in order for the remote to
receive power. The battery compartment slides out from the bottom
of the unit.

6.0 TROUBLESHOOTING
In the event of problems, first make certain that the input and output cables are no more
than 50 feet long (for signals to 1080i resolution) and are of the highest possible quality.
Next, make certain that the Switcher is receiving power.
If all is well in these areas, remember that HDMI devices communicate with one another
so the source devices and destination device must be fully HDMI capable. In addition,
HDCP encryption requires additional processing which also is dependent on the
equipment you have connected to the sources and destination device. If you experience
problems using the 1T-SX-632 or 1T-SX-634 HDMI Switcher, you should attempt to
determine what is wrong by attaching each of the source devices – one at a time –
directly to the destination device using the same cables you are using with the
expanded system. This is a way of determining if the problem is due to bad cables or a
problem with the other devices. If you are unable to obtain a signal using this simplified
path, suspect the cables, the source device(s) or the destination device.
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:

support team will respond within a short period of time.
