Troubleshooting
5.1
Power
In order for your LK202-25/VK202-25
to function correctly, it must be supplied with the appropriate
power. If the screen is not illuminated, power may not be applied correctly. Try 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 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.
5.2
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.
