Troubleshooting
3.1
The display does not turn on when power is applied.
• First, you will want to make sure that you are using the correct power connector. Standard floppy
drive power cables from your PC power supply may fit on the Power/Data Connector however they do
not have the correct pinout as can be seen in figure 9 on page 5. Matrix Orbital supplies power cable
adapters for connecting to a PC, which can be found in the Accessories Section on page 2.
