Troubleshooting

Power

In order for your Matrix Orbital display

to function correctly, it must be supplied with the appropriate

power. If the D2 power LED near the top right corner of the board is not illuminated, power is not

applied correctly. Try following the tips below.

?

First, make sure that you are using the correct power connector. Standard floppy drive power

cables from your PC power supply may fit on the Communication/Power Header;

however they

do not have the correct pin out to provide power. Matrix Orbital supplies power cable adapters

for connecting to a PC, which can be found in the accessories section.

?

Next,

check the power cable which you are using for continuity. If you don't have an ohm

meter, try using a different power cable, if this does not help try using a different power supply.

?

If power is applied through the DB9 connector, ensure that the Power Through DB9 Jumper

is

connected.

?

If changes have been made to the protocol select block, ensure all the appropriate Protocol

Select Jumpers

are connected and all unused protocol jumpers are disconnected.

?

The last step will be to check the power interface connector in use on your display. If the power

connections have

become loose, or you are unable to resolve the issue, please contact Matrix

Orbital

for more

information.

Display

If your

display

is powered successfully, the Matrix Orbital logo, or user created screen should display on

start up. If this is not the case, check out these tips.

Ensure the contrast is not too high or too low. This can result in a darkened or blank screen respectively.

See the

?

Manual Override

section to reset to default.

?

Make sure that the start screen is not blank. It is possible to overwrite the Matrix Orbital logo

start screen, if this happens the screen may be blank. Try writing to the display to ensure it is

functional, after checking the contrast above.
