APPLICATION DIAGRAMS

ALTINEX includes a remote control switch with the SW1956CT. The remote switch has a 6 ft cable and
may used to control the switcher manually.
When the remote control switch is connected to the INPUT SELECT jack, INPUT 1 will be selected if the
channel select contact is closed. INPUT 2 will be selected if the channel select contact is open.
The switching will be identical whether there are one or two active signals. The LEDs located next to the
input ports indicate which input is selected.

OPERATION

Step 1. Connect the ALTINEX power adapter that

Auto-Switcher. The SW1956CT will operate
successfully as long as cables are attached
properly and other technical specifications are
followed.
is supplied with the unit to the power port.
CAUTION: The POWER port and the
INPUT SELECT port use the
same connector type. Make
sure the power adapter is
connected to the POWER
port.
AUTO-SWITCH MODE
The SW1956CT automatically selects the INPUT 2
port if there are no active signals present. If there is
an active signal on INPUT 2 and not on INPUT 1,
then the SW1956CT will maintain INPUT 2 as the
active port. However, when an active signal is
applied to INPUT 1, the SW1956CT will switch to
INPUT 1.
Step 2. The POWER LED and the INPUT 2 LED
should turn on.
Step 3. Connect the SW1956CT inputs to the
outputs of the Twisted Pair transmitters.
Step 4. Connect a cable from the output port of
the SW1956CT to the input port of the
Twisted Pair receiver.
If there are active signals on INPUT 1 and
INPUT 2, the SW1956CT will automatically switch
to INPUT 1.
Step 5. If the remote control switch is to be used,
MANUAL SWITCH MODE
connect it to the INPUT SELECT port.
Manual override is accomplished via a contact
closure on the INPUT SELECT jack. Manual Switch
Mode disables auto-switching.
CAUTION: The POWER port and the
INPUT SELECT port use the
same connector type. Make
sure the control switch is
connected to the INPUT
SELECT port.
Included with the SW1956CT is an external manual
switch with a 6 ft cable. This switch may be used
for manual control, or the contact closure may be
made from a control system. This port uses a
2.5 mm mini-coaxial remote-control jack and it is
located next to the Twisted Pair output.
Step 6. Verify that the picture quality on the
display is good. If a signal is not being
received, make sure that the display is
compatible with the resolution of the
computer graphics card.
INPUT 1 will be selected when the remote control
switch is connected to the INPUT SELECT jack and
the contact is closed. INPUT 2 will be selected if
the contact is open.
CAUTION:
The connector used for the INPUT
SELECT port is the same type as is
used for the POWER connector. Use
caution to ensure the switch is
connected to the correct port.

TROUBLESHOOTING GUIDE
8
We have carefully tested and have found no
problems in the supplied SW1956CT unit.
However, we would like to offer the following
suggestions:
Solution 1: Remove the input signals from the
switcher. If the IN 2 LED is off, call
ALTINEX at (714) 990-2300. If the
IN 2 LED is on, see Solution 2.
8.1 POWER LED IS OFF
Solution 2: Connect a properly formatted signal
from an ALTINEX Twisted Pair
transmitter to INPUT 1. If the
switcher does not switch to
INPUT 1, see Solution 3.
Cause 1: The power adapter is installed
wrong.
Solution 1: Make sure the adapter output is
connected to the POWER input jack
on the unit. Check the unit carefully.
The POWER input jack and the
INPUT SELECT jack are the same
type. If the POWER LED is still not
on, see Solution 2.
Solution 3: Bypass the switcher and connect the
output of the transmitter directly to
the input of the receiver. If the
display is good, then call ALTINEX
at (714) 990-2300.
Solution 2: Make sure the adapter is plugged
into a proper AC outlet that has
power. If the adapter has AC power
and the POWER LED is still off, see
Cause 2.
8.3 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 wrong power adapter is
installed.
Solution 1: Please use the ALTINEX supplied
external adapter (9 V, 500 mA). If
Cause 2: Manual override is on.
the POWER LED is still not on,
Solution: Make sure there is nothing
connected to the INPUT SELECT
port on the switcher. If there is
nothing connected, see Cause 3.
please
call
ALTINEX
at
(714) 990-2300.
8.2 UNIT DOES NOT AUTO-SWITCH
Cause 3: Signal is bad or missing.
Cause 1: The manual override switch is
installed.
Solution 1: Make sure the switcher output is
connected to the Twisted Pair
receiver input and the receiver is on.
If there is still no display, see
Solution 2.
Solution: Remove the connection to the
INPUT SELECT jack on the unit. If a
plug is installed in the jack, the
SW1956CT will not auto-switch
properly. If the unit does not
auto-switch with the plug removed,
see Cause 2.
Solution 2: Remove both inputs to the switcher
and connect the active signal from
the Twisted Pair transmitter output
to INPUT 2. If there is still no
display, see Solution 3.

Solution 3: Bypass the switcher and connect the
output of the transmitter directly to
the input of the receiver. If the
display is good, then call ALTINEX
at (714) 990-2300. If there is still no
display, see Cause 4.
