Hello fuzzy,

Thank you for posting on the forum.
I will reach out via support queue and we will update the resolution here.

Hello Pierre,

Thank you for posting on the forum.

If you please try this:
From command line, run MatrixOrbitalFWU.exe with "RecoveryMode" as an argument.

Let me know how it turns out.

Thank you,

Good to hear you got it working, Michael.
Thank you for sharing your code here.

Hello Sean,

Please check Return Message for command 254 55 in the manual.
37645 is the correct module number for the GTT70A-TPC
37636 is for the TPR model; sorry the manual only lists the TPR models

Thank you,

Hi Michael, Did you try to turn flow control off on the GTT? Please check that the autoexec file includes the command to turn the flow control off. Or, if you have left the GTT default (flow control on), and turned the flow control on on your Linux host, did you connect the CTS/RTS lines to the GTT?...

Glad to hear that you resolved the issue.
Thank you,

Thank you,

Hello Michael, Thank you for posting on the forum. I see that you have flow control off on your port settings. Please note that the GTT has default flow control on. You can choose to have it off via the GTT Designer project. Can you also please try a simple query command like gtt_get_protocol_versio...

You may please check command 254 5 from the manual . With I2C, all communication transactions are master initiated. To read back replie...

Hello Sean,

It looks like you are addressing the GTT70A with 0xA0. Can you please try 0x50?

Thanks,

Hello Sean, Thank you for posting on the forum. I think you have done pretty good troubleshooting. My first thought was for turning off flow control which you have done. Please make sure though that command sent is 254 58 0. If this still does not work, I think the TX line may have been damaged as y...

Hello madz,

I apologize for not getting back right away.
Yes, that is correct, a check for 202 245 or 203 245 as command parameters is done.

Thank you,

Hello koyocik88, Thank you for posting on the forum. The important thing to note on macros: The macro feature is only suitable for use with display lists and not as part of a co-processor list, as the co-processor would regard the Macro command parameters as values rather than pointers to the REG_MA...

Update: Flickering was rectified by powering the HTT50G separately using the barrel jack (separate power source, not from USB).
