Troubleshooting
The Red/Green LED on the front of the EP1 Programming Dongle indicates the
status of each RTU firmware upgrade as follows:
Green LED
• On continuously - Indicates that the firmware in the Q03 and the EP1 are
verified to be identical. No license was used.
• Flashing – Indicates that the firmware in the Q03 has been upgraded to that
in the EP1 and verified. One license has been used.
Red LED
• On continuously – Indicates that the firmware was installed into the Q03 but
did not verify. No license was used. Check that the jumper J8 is properly
installed. The RTU should be reprogrammed by repeating steps 4 onwards as
described above. If the fault persists then a fault may have occurred in the
RTU.
• Flashing Code 2 – There are no licenses remaining on the EP1 Programming
Dongle.
• Flashing Code 3 – The RTU firmware installed in the EP1 is either corrupted
or missing.
• Flashing Code 4 – The EP1 has developed a hardware fault and should be
returned to QTech for servicing.
Flash codes are a stream of flashes separated by a gap of approximately one
second.
