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
??
. Matrix Orbital supplies power cable adapters for
connecting to a PC, which can be found in the Accessories Section on page 2.
•
The next step is to 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.
•
The last step will be to check the
Power / Data Connector
on the GLK12232-25-SM. If the
Power
/ Data Connector
has become loose, or you are unable to resolve the issue, please contact Matrix
Orbital see 16.6 on page 64 for contact information.
3.2
The display module is not communicating.
•
First, check the communication cable for continuity. If you don’t have an ohm meter, try using a
different communication cable. If you are using a PC try using a different Com port.
•
Second, please ensure that the display module is set to communicate on the protocol that you are
using, by checking the
Protocol Select Jumpers.
To change the protocol used by the display module
see Section 2.2 on page 8.
•
Third, ensure that the host system and display module are both communicating on the same baud rate.
The default baud rate for the display module is 19200 bps.
