4.0 CONNECTING THE HARDWARE
Please study the panel drawings below and become familiar with the signal input,
outputs, power requirements/inputs plus any controls present.
The front panel contains the power switch and LED Power Indicator, the Infrared
Sensor window and the four input selectors plus LED indicators that show which
input has been selected.
MX-3141PCA Front Panel
MX-3141PCA Rear Panel
From left to right, the rear panel features the RS-232 connector and five 3.5mm
type connectors for the Left and Right analog audio channel I/O.
To the right of the RS-232 and Audio connectors are a Video output connector
plus four identical sets of Video input connectors for channels 4, 3, 2 and 1. They
provide the YPbPr/PC RGB Video output and accept the YPbPr/PC RGB Video
inputs.
Finally, at the extreme right is the power connector used to connect the AC
power adapter.
The user should connect the inputs using high quality, known good cables,
connect the RS-232 cable if used and finally connect the video and appropriate
audio outputs to a monitor or projector or other destination device, again using
high quality, known good cable.
After connecting the signal cables, the AC power adapter should be connected,
first to the MX3141PCA and then to the AC power source.

5.0 OPERATING THE MX-3141PCA
Once the signal cables and AC power adapter have been connected, the
switcher can be turned on using the front panel power switch.
If the appropriate signals have been applied to the inputs, a high quality signal
should appear on the monitor or projector as each input in turn is selected. As
previously mentioned, the user can freely intermix PC video and YPbPr
Component video as inputs to the MX-3141PCA. It is important however to
realize that the monitor or other device connected to the switcher’s output must
be capable of displaying both PC video and YPbPr video else there will be faulty
displays or no display present. Finally, gain is unity so the output should mirror
the inputs in all cases. Note: Audio I/O is line level. It is not possible to directly
feed speakers or receive audio from a source speaker output. Damage may
result if attempted.
5.1 OPERATING THE MX-3141PCA USING THE INCLUDED IR REMOTE
Operation of the switcher via the included Infrared Remote Control is a matter of
simply pointing the remote at the MX-3141PCA and selecting the appropriate
input on the remote control. In order for the remote to function properly, the small
square window on the front of the MX-3141PCA must be unobstructed and not in
sunlight or extremely bright artificial light and the distance from the IR remote and
the switcher should not be more than found in a standard residential room.
6.0 TROUBLESHOOTING
Most problems encountered with the MX-3141 series of products relate to faulty
cables or incorrect signal levels from the sources.
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.
