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. 

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.
