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.

INSTALLING YOUR SW1956CT  
6
OPERATION  
7
Step 1. Connect the ALTINEX power adapter that  
There are no settings to adjust on the SW1956CT  
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.

improperly formatted.  
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.
