5.0 Troubleshooting
This section has been written to help eliminate operator error. It does not describe how to repair
damaged equipment.
The control connections are properly connected, yet the system is not communicating.
It is possible that the system needs to be biased or terminated. Refer to Appendix A.
The front panel LED/LCD is not lit.
This indicates the unit is not receiving power. Check to see if the power switch is in ON. Make
sure that the AC cables are properly connected. Check the fuse located just above the power
cord. Verify that the AC source is available.
The power supply LED is on but the LCD is not.
Contact Quintech for service.
No signal is passing at all. The connection is shown as being made but no switch occurred.
First, be certain that all coaxial cables are properly connected, and that all control cables are
connected and in good working conditioning. Type in the desired path again.
Type in a different path to verify that the units are switching. If the units are switching, verify
that the signal you requested is actually there (the SRX system is DC blocked and will not allow
receivers to power LNBs). It is useful to monitor the system with some type of analyzer.
Make sure that the SRX routing is properly configured. The SRX will only switch up to the
set maximum size. If the controller unit is configured to utilize a larger size than is physically
available, it will show routing crosspoints that are not physically available.
The unit does not remember the previous switch settings/switch size after power has been
removed and restored.
