1. Introduction
1.1 Introduction to TL-SM3X1-HD
The TL-SM3X1-HD is a 3x1 video switcher with three HDMI inputs and one HDMI
output. The unit supports HDMI video resolutions up to 4K@30, as well as multichannel
audio.
The TL-SM3X1-HD supports two operating modes: auto-switch mode and manual
switch mode. When in auto-switch mode, the unit will automatically switch to a signal
input as soon as a new source is connected. When the active source is removed, the
unit will select the first source on the lowest numbered input.
In manual switch mode, the TL-SM3X1-HD will switch between connected inputs when
a control command is sent to the unit via IR or through a command sent by compatible
table inserts, or by using buttons on the front panel of the unit.
In addition to controlling the switching of the source inputs, the TL-SM3X1-HD also
controls a display connected via an HDMI cable via CEC commands. This allows for
automatic power on/off commands to be transmitted from the unit (as well as
connected table inserts) to the display, thereby providing a complete room connectivity
and control solution.
1.2 Features
l Three HDMI inputs & one HDMI output
l HDMI video resolution up to 4K@30Hz 4:4:4
l HDMI 1.4 & HDCP 1.4 compliant
l MHL support on HDMI input channel 1
l IR remote control & front panel control
l Integration with TechLogix table inserts for signal pass-through & remote control
l Micro USB firmware port

1) Separately connect HDMI signal cables between the HDMI sources and
HDMI ports of the table inserts.
2) Separately connect HDMI signal cables between the HDMI ports of table
inserts and the HDMI/MHL IN 1, HDMI IN 2 and HDMI IN 3 ports of the
TL-SM3X1-HD.
3) Separately connect three table inserts to the C1, C2, and C3 ports of the
TL-SM3X1-HD.

4. System Operations
4.1 Front Panel Buttons
The front panel buttons may be used for source selection. Video signals support autoswitching and manual switching (factory default).
4.1.1 Manual-switching
Press HDMI 1, HDMI 2 or HDMI 3 on front panel to select the corresponding input
source.
4.1.2 Auto-switching
Press AUTO to enter into auto-switching mode.
The auto-switching mode abides by the following principles:
Ø New input
When a new signal (or connection) is detected, the TL-SM3X1-HD switches to this
new signal automatically.
Ø Rebooting device
The TL-SM3X1-HD will save the last configuration before losing power. If the last
switching mode is auto-switching, once rebooted, the TL-SM3X1-HD will
automatically enter auto-switching mode, then detect all inputs and memorize their
connection status for future use. If the last displayed signal is still available, the unit
will output the signal. If not, the unit will detect all the input signals with priority
from HDMI 1 to HDMI 3.
Ø Removing signals
Should an active signal be removed, the TL-SM3X1-HD will detect all input signals
with priority from HDMI 1 to HDMI 3. It will transfer the first signal detected to the
display.
