ABOUT YOUR UT250-101 2
UT250-101
Under Table 8x4 VGA+Audio Matrix
Switcher with “Show Me” Keys+RS-232
Auto-Switcher
The UT250-101 is an 8x4 Video+Audio Matrix
Switcher designed to be mounted under a table as
part of an integrated audiovisual system. The
UT250-101 provides great flexibility for routing
multimedia signals from a single, convenient
location. Under Table solutions are ideal for
situations where it is too expensive or impractical to
install equipment directly into the furniture.
The UT250-101 accepts 8 computer/YPbPr video
inputs and 8 stereo inputs. The audio inputs accept
both left and right audio, and then combine them to
create a mono signal. The 4 video outputs function
as 2 independent dual outputs where any input can
be routed to 2 or all 4 of the video outputs. Each of
the 4 outputs can be switched independently using
RS-232 control. The audio output follows the last
switched input and delivers a balanced mono
output on both the left and right channels.
In addition to standard video and audio outputs, the
UT250-101 also has a 4TP (4 Twisted Pair) output
for each video output. These 4TP outputs can be
used with a compatible Twisted Pair receiver, like
the TP115-111, to transmit the video and audio
signals over long distances to remote projectors or
other multimedia presentation systems.
The latest generation of Twisted Pair devices uses
an innovative, patented technology* developed by
ALTINEX. The new signal processing technology
allows transmitting and receiving fully equalized
computer video signals, stereo, and audio signals
over long distances.
Input-to-output switching can be made from one or
all of the following methods: RS-232, contact
closures, auto-switching. RS-232 control is
accomplished from a computer or controller using
the RS-232 bus. Contact closures with LEDs
(“Show Me” keys) allow manual switching through
the Output Select Control inputs on the front of the
unit. These controls are designed for use with
momentary switches having built-in LEDs. Any
input can be switched to either, or both, of the dual
outputs and the LEDs show which connections are
active. The UT250-101 can also be configured for
auto-switching. In Auto-Switch mode, the
UT250-101 automatically switches to the lowest
number input with an active video signal applied.
Any selections made by a user from the Output
Select Control input override the Auto-Switch
feature.

INSTALLING YOUR UT250-101 6
Step 1. Decide how the UT250-101 will be
controlled: using contact closures on the
Output Select Controls, through computer
control using the RS-232 input, using
auto-switching, or all 3 methods.
If using the Output Select Controls, see
Diagram 6 for wiring information.
Step 2. Locate the best position for the
UT250-101, but do NOT mount it to the
surface until all the cables are prepared.
Step 3. Prepare the mating cables using
high-quality cables for best results and
durability. Make sure the cables are long
enough to allow for a service-loop and so
the cables can be neatly routed beneath
the table to their destinations.
Step 4. Secure the unit under the table using the
screws provided with the unit.
Step 5. Make all necessary connections to the
UT250-101.
Step 6. When making connections to the terminal
blocks (audio out, control, RS-232, etc.),
use 24-28 AWG stranded wire for best
results. Also, use multi-conductor cable
where possible. For example, a standard
4-conductor cable works well for the
RS-232 connection.
Step 7. Use the cable clamps provided to secure
the cables to the bottom of the table/desk.
Do NOT bend the cables too sharply
Step 8. Attach the cable support to the
UT250-101 as shown in Diagram 5. This
will help alleviate the strain of the cables
pulling from the connectors and protect
the cables from being accidentally pulled
free or damaged.
Step 9. After power is applied to the UT250-101,
the unit is operational.
OPERATION 7
7.1 MANUAL CONTROL
7.1.1 OUTPUT SELECT CONTROLS
The Output Select Control inputs on the front of
the UT250-101 allow 8 users direct control of
video switching. In this method, each user
typically has a control panel with 2 illuminated
switches along with video and audio inputs.
(See Diagram 6 for details and wiring
information.)
When a user presses a control switch, the video
and audio from that control panel are displayed
at the output of the UT250-101. Each switch
connects its corresponding input to 2 outputs,
either 1A/1B, or 2A/2B. Once the connection is
made, the LED for that switch turns on. If the
switch’s LED is on and the switch is pressed,
the output is disabled and the LED turns off. The
audio output follows the last video input
selected.
7.1.2 AUTO-SWITCH MODE
In Auto-Switch mode, the UT250-101
automatically switches to the lowest input
number with an active signal applied. For
example, if there is a signal on Input 4 and a
new signal is applied to Input 2, the outputs
defined with the Auto-Switch command will
switch to Input 2.
The Output Select Control inputs override
Auto-Switch mode. When a user selects an
input using an external switch, the UT250-101
automatically switches to the selected input.
In Auto-Switch mode, Input 8 is designed for use
as a logo input that displays when the system is
not in use. If Auto-Switch mode is enabled then
overridden by the Output Select Control inputs,
when all active inputs are removed from
Inputs 1-7, the UT250-101 automatically
switches to Input 8.
Auto-Switch mode must be set using the
RS-232 input. See the AUTO commands in the
following section for details.
400-0503-001

Page 15
DESIGNER SOLUTIONS
7.2 RS-232 CONTROL
The UT250-101 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.
7.2.1 RS-232 INTERFACE
The control commands for the UT250-101, are
in a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
3. Spaces are not legal characters.
Commands instruct the UT250-101 to perform
specific actions or request information. Some
commands do both simultaneously. A command
that instructs the UT250-101 only to perform an
action will generate feedback of “[ ]”. The open
bracket immediately followed by a closed
bracket indicates the card received a valid
command. If the command requested
information, the feedback generated by the
UT250-101 is the acknowledgement of having
received a valid command. Invalid commands
generate feedback that includes “ERR” plus an
error code.
Example: [ERR001] Error number
Commands ending in “S” will be saved into
memory. Commands not ending in “S” will still
be executed, but will not be restored when the
system is reset or powered off, then on.
7.3 DESCRIPTION OF COMMANDS
Each command consists of a function name and
an optional unit ID. Unit IDs are required if 2 or
more UT250-101s are to be controlled
individually over the same RS-232 bus. The unit
ID can be changed using the [SID] and [RSI]
commands that are described later.
Example: [ONU2]
ON = Function
U2 = Unit ID (only U2 executes ON)
Unit ID “U0” does not need to be included at the
end of a command string.
Example:
[ON]: Executed by U0
[ONU0]: Executed by U0
NOTE: Examples in this manual assume
the unit ID is U0 and do NOT
include the unit ID. If needed, the
unit ID for any unit can be specified
at the end of the command string as
shown above.
1. [STATUS]
This command displays the status of the unit.
Command Format: [STATUS]
Example:
Send the command [STATUS] to receive
feedback similar to the following:
Note: Preset connections are
displayed as already executed, but
do not take effect until after the
[SW] switch command is executed.
400-0503-001
OUT 1A - IN 1 ON
OUT 1B - IN 1 ON
OUT 2A - IN 1 ON
OUT 2B - IN 1 ON
AUDIO OUT - IN 1 ON
AUTO_SWITCH - OFF
If there is no card in slot 4, sending the [C4]
command will not return any feedback.

(1A, 1B, 2A, and 2B) will be enabled.
6. [OFFmX]
This command turns off one or more outputs.
Command Format: [OFFmX]
m = Output No. (m = 1 or 2)
X = Channel No. (X = A, B, or blank for both)
Example:
Turn off Output 1A by sending [OFF1A]. Outputs
1B, 2A, and 2B are unaffected.
Turn off Outputs 2A and 2B by sending [OFF2].
Outputs 1A and 1B are unaffected.
7. [OFF]
690-0268-001 = the firmware version
U0 = the unit ID
4. [ONmX]
This command turns on one or more outputs.
Command Format: [ONmX]
m = Output No. (m = 1 or 2)
X = Channel No. (X = A, B, or blank for both)
Example:

9. [InO*]
This command connects one input to all outputs.
Command Format: [InO*]
n = Input No. (m = # from 1 to 8)
Example:
Connect Input 1 to all outputs by sending [I1O*].
Input 1 is then connected to Outputs 1A, 1B, 2A,
and 2B.
10. […P]
This command sets the path for switching the
outputs, but it is not active until the switch
command, [SW], is executed. Switching
commands ending in "P" are not executed
immediately. The path for outputs on multiple
units or the same unit can be preloaded.
Example:
See the example for the [SW] command that
follows.
11. [SW]
This command immediately connects inputs and
outputs previously set with the PATH command.
The command switches all paths set on one or
more units on the RS-232 bus.
Example:
[I1O1AP] Nothing is physically switched.
[I2O1BP] Nothing is physically switched.
[SW] Inputs 1 & 2 are switched
simultaneously.
12. [AUTO*]
This command enables auto-switching to all
outputs. The UT250-101 automatically connects
the lowest numbered input with an active video
signal to all outputs: 1A, 1B, 2A, and 2B.
Auto-switching is automatically disabled when
an input is received on the Output Select Control
inputs.
Example:
Send the command [AUTO*] to the UT250-101.
If a video input signal is connected to any of the
inputs, that signal will be connected to all the
outputs. A valid video signal on Input 1 takes
precedence over Input 2, Input 2 over Input 3,
and so on.
13. [AUTO0]
This command disables auto-switching.
Example:
Disable auto-switching mode by sending the
command [AUTO0].
14. [AUTO1]
This command enables auto-switching to
Output 1. The UT250-101 automatically
connects the lowest numbered input with an
active video signal to Outputs 1A and 1B.
Outputs 2A and 2B remain unchanged.
Auto-switching is automatically disabled when
an input is received on the Output Select Control
inputs.
Example:
Send the command [AUTO1] to the UT250-101.
If a video input signal is connected to any of the
inputs, that signal will be connected to Outputs
1A and 1B only. A valid video signal on Input 1
takes precedence over Input 2, Input 2 over
Input 3, and so on.
15. [AUTO2]
This command enables auto-switching to
Output 2. The UT250-101 automatically
connects the lowest numbered input with an
active video signal Outputs: 2A and 2B. Outputs
1A and 1B remain unchanged. Auto-switching is
automatically disabled when an input is received
on the Output Select Control inputs.
400-0503-001

description will be displayed.
17. [?]
This command displays general information
about a unit and its status.
Command Format: [?]
Example:
Send the command [?] to receive feedback
status similar to the following.
[(UT250-101U0)(VR690-0268-001U0)
(MA1111U0) (ON1111U0)]
The feedback is broken down as follows:
(UT250-101U0)
(VR690-0268-001U0)
(MA1111U0)
(ON1111U0)
All status feedback is enclosed in brackets, “[ ]“.
Each data field within the status is enclosed in
parentheses. The first two characters identify
the status type. The last two characters are the
unit’s ID.
UT250-101 = Model number
VR690-0268-001 = Firmware version
MA1111 = Matrix connections
ON1111 = Output ON/OFF status
The I/O connections are read left to right
representing the four outputs (1A, 1B, 2A, 2B)
and the input to which each is connected. The
first digit shows the input number to which
Output 1A is connected. The second digit is for
Output 1B, and so on.
The ON/OFF status line is also read from left to
right as Outputs 1A, 1B, 2A, and 2B. A "1"
indicates the output is on and a "0" indicates the
output is off.
18. [STA1]
This command enables automatic feedback.
The command affects all units with
auto-feedback capability, not just the
UT250-101. The default is STA0, off.
Command Format: [STA1]

Command Format: [AFBm]
m = 1 for ON, 0 for OFF
Example:
Send 16 commands to the UT250-101 to
initialize the card. The required commands are
as follows:
[I1O1A],
[I2O1B],
etc.
22. [SIDn]
This command sets the UT250-101 to a new
unit ID. When assigning multiple IDs to several
units, connect only one unit at a time to the
RS-232 bus.
Command Format: [SIDn]
n = Unit ID (n = # from 1 to 9)
Example:
There are two UT250-101 units on the RS-232
bus, but they need to be controlled individually.
Connect only the first unit to the bus and then
send [SID1]. This unit is now U1. Disconnect the
first unit and connect the second unit. Now send
[SID2] to the second unit. The second unit is
now U2.
23. [RSI]
This command resets the unit ID to U0.
Command Format: [RSI]
Example:
Send the command [RSI] to reset unit ID U1
assigned above back to U0.
Send the [AFB] command first, and then the
switching commands.
[AFB0],
[I1O1A],
[I2O1B],
etc.
[AFB1]
In the above example, the brackets, “[ ]”, will not
be displayed after each command is executed.

TROUBLESHOOTING GUIDE 8
We have carefully tested and found no problems in
the supplied UT250-101; however, we would like to
offer suggestions for the following:
8.1 POWER LEDS ARE OFF
Cause 1: The unit is not plugged in.
Solution: Make sure the power adapter is
plugged into a working AC outlet
and that the adapter’s DC end is
plugged all the way into the
UT250-101. If both LEDs are still not
ON, see Cause 2.
Cause 2: The unit has a problem.
Solution: If one power LED is on, but the other
is not then the UT250-101 may have
a problem. Please call ALTINEX at
(714) 990-2300.
8.2 NO DISPLAY
Cause 1: The source has a problem.
Solution: Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no display, see Cause 2.
Cause 2: The output is not selected.
Solution: Verify the connection status of the
UT250-101. (See RS-232 accessible
commands in Section 7.) If no
display is present, see Cause 3.
Cause 3: Cable connections are incorrect.
400-0503-001
Solution: Make sure that cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no display present, see
Cause 4.
Cause 4: The display has a problem.
Solution: Make sure the display is powered
and turned on. If there is still no
display, please call ALTINEX at
(714) 990-2300.

8.3 NO RESPONSE
Cause 1: The unit is n ot recognized.
Solution: Reset the unit by turning the system
power off and then on again. Send
the [STATUS] command to see if
there is communication with the unit.
If there is no feedback, see Cause 2.
Cause 2: Unit is disconnected from RS-232.
Solution: Check the RS -232 connection to the
unit. Make sure the terminal block
connector is pushed all the way in
and that all the wires are connected.
If the unit is still not recognized, see
Cause 3.
Cause 3: Communication settings are bad.
Solution 1: Verify the communication software
settings. The UT250-101 default
settings are as follows:
Baud Rate..9600 Flow......... None
Data Bits..... 8 Parity....... None
Cause 2: The wrong output is selected.
Solution: Check the status of the unit using
the RS-232 commands in section 7.
Verify the correct input-to-output
connection is selected and enabled.
If no sound is present, see Cause 3.
Cause 3: Cable connections are incorrect.
Solution: Make sure that cables are
connected properly. Also, make sure
that the continuity and wiring are
good. If there is still no sound
present, see Cause 4.
Cause 4: Destination amplifier has a
problem.
Solution 1: Make sure that the destination
amplifier is powered. If there is still
no sound, see Solution 2
Solution 2: Set the volume of the destination
amplifier to a reasonable level. If
there is still no sound, see
Solution 3.
Stop Bits.....1
Solution 2: Verify the correct port is selected in
the communications software:
COM1, COM2, etc. If there is still a
problem, please call ALTINEX at
(714) 990-2300.
8.4 NO SOUND/SOUND TOO LOW
Cause 1: The source has a problem.
Solution: Check the source and make sure
that it is working at an appropriate
volume level and all source
connections are correct. If the
source is working and there is still
no sound, see Cause 2.
Solution 3: If the video output is working and
only the audio is missing, there may
be a problem with the UT250-101,
call ALTINEX at (714) 990-2300.
8.5 NO TWISTED PAIR OUTPUT
Cause 1: The output is not selected.
Solution: The TP output is the same as the
VGA output. Verify the connection
status of the UT250-101. (See
RS-232 accessible commands in
Section 7.) If no display is present at
the TP receiver, see Cause 2.
Cause 2: No input signal applied.
Solution: Make sure that the selected input
has a valid image applied. Connect
a local monitor to the VGA output of
the UT250-101 that corresponds to
the TP output. If an image is
present, there may be a problem
with the UT250-101. Call ALTINEX
at (714) 990-2300.
