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.
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 cables, connect the RS-232 cable if
used and finally connect the video and appropriate audio outputs to a monitor, projector
or other destination device. 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 UNIT
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 Control via the Infrared Controller
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. The distance from the IR remote and the switcher should not be more than found in a
standard residential room.
5.2 Control via RS-232 Option
Using appropriate control codes, it’s possible to switch to any input 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.
The RS-232 control connections are as follows:

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.
Note: It is strongly recommended that you use premium cables in order to achieve
maximum distance cable runs and the best performance possible.
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.
