Hello,

I am about to purchase a GLK12232-25-SM or -WBL display and I have a couple questions.

First, what are the differences between the -SM and -WBL displays? Looking through the manuals for each, it seems like the only difference is the arrangement of pins and the additional TTL option for the -SM display. Is this all?

Second, how are the displays attached to a computer? The manuals mention that a power connector and a serial cable are needed. For the serial cable, it seems like the "Serial Cable -4BR" would suffice. However, it seems like a power connector would not be necessary because the "Serial Cable -4BR" seems to be bringing 5V to the display. Is this true? Otherwise, what power connector would I use?

Please help.

Hi Eric,

Thank you for posting at our forums.

The big difference between the -SM and -WBL is the physical size of the -WBL. The PCB board on the WBL is a little larger, and it also doesn't have the TTL option like you have mentioned.

If you were going to attached the units to a computer, you will need to create some kind of mount. For communications, you will need to use either the serial -4BR, and an unmodified floppy power cable to power the display. You could also use the communication and power cable found at http://www.matrixorbital.com/index.php? ... munication
If you were using the -WBL, you will need to do a slight modification to the -4BR cable or the communication and power cable. You will need to interchange the two middle wires because TX and RX on the models are different.

I hope this helps you out. If you have anymore questions or concerns, please feel free to post.

Best Regards,
