Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

Retro C

Step 1: Locate the computer that runs your software. The Retro C’s computer is located in the touchscreen enclosure.

Step 2: Turn off the computer or pi by pressing and holding the power button (has a blue light) on the top right side of the computer

Step 3: Next locate the USB thumb drive already inserted into the PC and remove it. NOTE: If this drive is re-inserted into any USB port on the computer/touchscreen it can cause the computer to not boot up properly. NOTE: There are four USB ports on the button side of the computer it could be in any one of them.

NOTE: the USB thumb drive is very small and easy to miss.

Step 4: Insert the new USB drive into the same port you removed the other one from.

Step 4: Power the touchscreen on

Confirm the Result

After checking all connections and reinstalling covers, restore power through the approved startup procedure. Confirm that the correct device comes online without a disconnected-drive or communication warning, then test its command, direction, and stopping response in a controlled mode.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
