2. Installation Procedures
Note: Download and read the entire online manual to become familiar with the UT260-102 and for detailed information.
Step 1: The enclosure mounts under the table using the mounting brackets included.
Step 2: Connect input cables from the sources.
Step 3. Connect the digital output directly to the HDTV. If there is at least one input signal present, an image appears on the TV.
Step 4. Apply power to the unit using the power adapter provided.
Step 5. The UT260-102 is ready for use. Auto-switch is one of the default configuration settings. If a signal is removed, the switcher
automatically switches to another input if a signal is present.
Step 6. The UT260-102 may be controlled using RS232 commands from a
controller, or using simple momentary push button switches wired to
the terminal block on the rear panel. See the full user guide for details.
On the rear terminal block, there are input select controls, output LED controls,
and RS232 control pins.
The input select controls are activated using a momentary contact closure to ground to between each input
pin and ground. The LED output pins drive LEDs to indicate a signal is present (flashing) or active on the
output (solid), same as front panel LEDs. The RS232 controls can be used to control or configure the
UT260-102.
See the top label of the UT260-102 for details, or refer to the complete online manual.
3. Warranty and Return Policies
Please visit the ALTINEX website at www.altinex.com for details on warranty and return policies. In the case of a unit needing repair,

5. About Your UT260-102
Multi-format inputs for VGA/DP/2 HDMI
Supports HDMI 2.0 with 4K@30Hz or 4K@60Hz 4:2:0
HDCP compliant
Optional internal EDID or live EDID
RS232/Button/Contact closure for switching
Auto/Manual switching mode
Analog audio de-embedded at the output
Output mute function
Power standby mode
The UT260-102 is a multi-format switcher with HDMI, VGA, and Display Port inputs to an HDMI output with analog audio de-embedded.
It supports RS232 and Contact Closure for remote control. The switcher is HDCP compliant and supports a default internal EDID or live
EDID from the display.
The switcher may be used in auto-switch mode, controlled manually using contact closure switcher, or controlled via a controller using
RS232 commands. The auto-switch feature automatically tells the switcher to connect the newest input to the output display. This
feature works great in many applications and eliminates the need for external hardware or controls.
The contact closure switching uses momentary contact closures to select among the four inputs. In addition to the contact closure input
controls, the switcher provides LED driver outputs that can be used to control LEDs either built-in to the momentary switch or part of a
user control interface.
The RS232 control provides input select control as well as other advanced features like video output mute and EDID select. The RS232
interface is also used to configure the switcher if the default settings are not exactly what is required by the application.

7. Operation
Users connect their device (phone, laptop, etc.) to one of the
input connectors/cables above the table surface. Their video
input is automatically routed to the HDMI output where it is
displayed on the external display. Auto-switch is the default
configuration, but may also be disabled for use with contact
closures or a control system.
7.1 LED Indicators
The front panel has four LEDs representing the four inputs.
The LEDs are off if there is no signal present, flashing if a
signal is present but not selected, and solid if an input signal is
present and displayed on the output HDMI connector. The rear
panel LED outputs function the same as those on the front
panel. The POWER LED is on and solid red when power is
applied. The OUT LED is off when there is no display
connected to the HDMI output, it flashes if a display is
connected but there is no signal present on the output of the
UT260-102, and solid when both signal and display are
present.
7.2 Input Selection
7.2.1 Auto-switch
By default, the UT260-102 is configured with auto-switch
enabled. In auto-switch mode, the switcher automatically
selects the last signal connected and displays its video on the
output. When an active input signal is removed, the switcher
automatically switches to the next available input in the
following order of priority: HDMI-A, HDMI-B, DisplayPort, and
finally VGA. Auto-switch can be disable and priorities changed
using the RS232 connection to reconfigure the switcher
defaults.
7.2.2 Input Select Contact Closures
The switcher rear panel terminal block connectors allow the
switcher to be controlled manually. Momentary switches can
allow users to select their video at will during a presentation.
See Diagram 3 for wiring details.
7.2.3 RS232 Control
A controller may also be used to control the switcher using the
RS232 commands in the next section. RS232 protocols can be
used to control the switcher or alter its default configuration.
7.3 RS-232 Control
The UT260-102 has many advanced remote-control
capabilities accessible through standard RS-232
communication. Control may be accomplished through a
computer, control system, or any device capable of RS-232
communication.
If the computer/controller in use does not have a DB9
connector for serial communication, use a USB to serial
adapter.
7.3.1 RS-232 Serial Port Settings
In order to configure the switcher or to control it using RS232
communication, make sure the communication software is set
for the following:
Baud Rate...........9600
Data Bits.............8
Stop Bits .............1
Parity...................None
Flow....................None
The baud rate may be changed depending on the user
requirements. See the Description of Commands section for
details.
7.3.2 RS-232 Interface
The control commands for the UT260-102 are in a simple
ASCII character format and must include a carriage return
0x0D at the end of the command string.
7.3.3 Feedback from Switcher
Feedback from the switcher is enclosed in parentheses "(…)"
and displays the new settings of the switcher.
7.4 Description of Commands
Each command consists of either an ampersand or question
mark, following by a command/query and finally a carriage
return.
Example: ? R <cr>
? = Query
R = Function (route)
<cr> = carriage return (0x0D)
Important: Commands must be sent in one contiguous group
without delay. For example, if you type the
characters by hand, the switcher will most likely
not recognize the command. Type the commands
and then paste them to a terminal window, or use
a controller to send the commands as a single
block.

8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied UT260-102. However, we would like to offer suggestions for the
following:
Switcher
Symptom
Resolution
No Audio with VGA Input
1. Make sure the VGA audio source is connected to the 3.5 mm audio input on the
switcher.
2. Check the audio source to make sure the audio is playing and that the volume is turned
up to a reasonable level.
Poor Output Image
1. Verify the cable between the switcher output and the display is a genuine HDMI cable.
2. Troubleshoot with a lower gauge shorter distance HDMI cable.
RS232 Commands Not
Recognized
1. Make sure to send all the characters in a single burst using PASTE or programming a
controller button. Typing the characters individually results in the switcher not
recognizing the individual characters as a whole command.
System Failure
1. Please call the ALTINEX Customer Service Department at [phone] to have the
unit repaired.
