Yes, the Rx and Tx pins will remain in the same orientation for TTL as they were for RS232. You can apply 5 Volts ONLY via the DB9. CAUTION: Voltage input via the DB9 is not regulated, therefore you must apply 5 Volts only. To apply voltage via the DB9 connector you must solder the "solder jump...

Hi Stocky,

To adjust contrast, it has to be done via firmware. With that being said, can you please contact Tom at tlam@matrixorbital.ca and he we will discuss some RMA options with you. I appreciate your patience regarding this matter.

Thanks!

Unfortunatley the preset values are the only values that are currently available. The limitation of our controller establishes this guideline. We have looked into ways of making the frequency totally customizeable and this will not be available until our next revision. I apologize for any inconvenie...

You can send them to my email account: myero@matrixorbital.ca

Can you verify that it is a 12V module? If not, can you please take a pic of the PCB and we will let you know. Please, do not attempt to apply power if unsure of the voltage requirements.

Hi madlan,
