Troubleshooting an SDS
This section lists some common problems and their causes. If the
information below does not provide a solution, contact Quatech
technical support.
Problem Cause Solution
The SDS does not
turn on and no
LEDs light up.
¾ The SDS or the
power source is
damaged, or the SDS
does not have power.
1. Make sure that the power source is properly
connected to the SDS’ power jack.
Caution! Only use the Quatech +5 V power source.
2. Make sure the power adapter is connected to a
functioning electrical outlet.
3. Contact Quatech tech support.
The serial device
will not respond
even though the
SDS is functioning.
¾ The serial device is
not powered up; the
serial cable is
wrong/damaged, or
the serial port
settings are wrong.
1. Make sure the serial device is powered up.
2. Make sure the serial cable is properly
connected to the serial device and to the SDS.
3. Verify the cable pinouts.
4. Try a different serial cable.
5. Try a different port on the SDS.
6. Review your serial device literature. Make sure
the settings it specifies match those the SDS is
using (check the SDS serial port settings using
the Web interface).
7. Try plugging the serial device directly into a
PC.
The search utility
does not find the
SDS.
Could be due to a
variety of causes:
¾ Check power
¾ Check status
Verify that the blue Power LED is lit.
If the Power LED is not lit,
1. Check the power connection.
2. If power is connected properly, contact Quatech
tech support.
Verify that the green Status LED is lit.
If the Status LED is not lit,
1. Check the firmware version.
a. If the SDS firmware has been upgraded
from the factory default, reset the SDS to
the factory default. See page 9.
b. If the procedure to return to factory default
fails, contact Quatech tech support.
2. Cycle power on the box and wait approximately
30 seconds. If the Status LED still does not
light, contact Quatech tech support.
Note: Any unauthorized repairs
or modifications will void the
SDS' warranty.
