Task: IlluminatedStarBand Model 360 Modem - Troubleshoot LED
Symptom: PC Light Not Illuminated
Diagnosis #1: Defective Ethernet or USB Cable
Resolution #1: If another port on the PC is available, move the connection to that port.
If not available or if the PC light is still not on, switch between USB and Ethernet if
possible.
Note: Always power the modem off when switching between ports to ensure internal
switching of unit takes place correctly. Always use the cables provided with the modem.
If switching from Ethernet to USB solves the problem, you may need to load the USB
drivers - follow the prompts.
Diagnosis #2: Bad PC Port
Resolution #2: Plug the modem into alternative PC or Laptop if available. If the PC light
illuminates, there is a problem with the port on the original PC. If the PC light does not
illuminate the modem may defective. (See Defective Modem in the previous section.
Diagnosis #3: Defective LED
Resolution #3: Hover the mouse over the Mission Control Icon. If the test prompt
reads anything other than a PC problem, the LED is defective.
If troubleshooting is unsuccessful, contact StarBand Tech Support at: 1-888-424-4121.
Diagnosis #1: Bad transmitter due to physical damage.
Resolution #1: Contact StarBand to request replacement ODU.
Diagnosis #2: Shortage in the transmitter.
Resolution #2: To determine if there is a short in the ODU, remove the transmit IFL
cable from the ODU and set the multimeter to measure resistance in ohms. Measure the
resistance from the center conductor of the ODU to the outer shield (use a Type F male-
to-male adaptor or paper clip to reach the center conductor on the ODU connector. This
should be an “open” with the multimeter display showing “OL” (for over load - too high a
resistance to measure). If the display shows a low resistance value (e.g. less than 1
ohm) then there is a short in the ODU indicating it has failed and must be replaced.
Note: If the ODU is determined to be defective after following these steps, replace the
ODU with spare (if available) to confirm that the unit is defective. Upon confirmation,
contact StarBand for replacement.
Note: Reference StarBand FSB SB-0018-1.00 for additional information.
Task: ODU Failure
Symptom: VSAT has receive lock but cannot connect with the hub or
significantly reduced transmit signal performance indicated by low co-pol and/or
high cross-pol measurement.
