No. 1582 Re: CSE-M73 firmware 2.0A problem 2018-04-17

Dear Luca,

Thank you for choosing our products.
We would like to answer regarding your inquiry.

In general, the serial communication error is unlikely caused by a firmware incompatibility.
Since you can perform loopback test successfully, it seems that there is no problem with the CSE-M73 device.
Please make sure there is no problem with physical cable and serial parameters.
Besides the serial communication, the data transmission issue may be in TCP/IP connection (IP conflict, firewall, etc.).
Could you please check this list to verify your configuration:

In case there is no problem with the configuration, could you please give us more detail about your application and how exactly does the issue happen?


From firmware 2014-12-29[1.7A] we change new CPU version, therefore downgrading firmware makes devices not work.
We recommend that users keep using the latest firmware for the best performance.


Please feel free to contact us if you have any inquiry.
Best Regards,
