FIX or WORKAROUND
1. Close out of the software and restart the computer.
2. Log back in to the computer but do not launch any software.
3. Reset the SQD2/EPC by toggling the recessed reset button next to the power button of the SQD2.
1. Insert a small-diameter object such as a paper clip, piece of tubing, or hex key into the hole next to the power
button of the SQD2.
2. Press and hold the reset button for 3 seconds, and then release the reset button.
3. Wait for the SQD2 to fully initialize. You will hear the diverter valve actuate and three chimes/beeps (this
could take 5-10 minutes).
4. The LEDs on the SQD2 should be green for power and not illuminated for the "Operate" LED.
5. Open command prompt, run the command "ping epc -t", and ensure that the EPC replies.
6. If the EPC replies, launch software and confirm that communication is established.
