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:
8.1 THE POWER LED IS OFF
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 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.
Cause 2: The wrong power adapter is
installed.
Solution 1: Please use the Altinex supplied
external adapter (9V, 500mA). If the
POWER LED is still not on, please
call ALTINEX at [phone].
8.2 UNIT DOES NOT AUTO-SWITCH
Cause 1: The manual override switch is
installed.
Solution: Remove the connection to the
INPUT SELECT jack on the unit. If a
plug is installed in the jack, even
without a switch, the unit will not
auto-switch properly. If the unit does
not auto-switch with the plug
removed, see Cause 2.
Cause 2: The signal is not active or is
improperly formatted.
Solution 1: Remove the input signals from the
switcher. If the IN 2 LED is OFF, call
ALTINEX at [phone]. If the
IN 2 LED is ON, see Solution 2.
Solution 2: Connect a properly formatted signal
from an Altinex CAT-5/6 Transmitter
to INPUT 1. If the switcher does not
switch to INPUT 1, 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 [phone].
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: Manual override is ON.
Solution: Make sure there is nothing
connected to the INPUT SELECT
port on the switcher. If there is
nothing connected, see Cause 3.
Cause 3: Signal is bad or missing.
Solution 1: Make sure the switcher output is
connected to the CAT-5/6 Receiver
input and the receiver is ON. If there
is still no display, see Solution 2.
Solution 2: Remove both inputs to the switcher
and connect the active signal form
the CAT-5/6 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 [phone]. If there is still no
display, see Cause 4.
