Hi all,
I am using the PHS8-P in an embedded enviroment. Sometimes a receive an "incomplte frame" answer from the muxer and I could not catch the problem.
Do you have any ideas, why it is happened?
Many thanks.

Hello,
Could you please write more details: ati1 response from the module, device and operating system that you are using with the module, driver version.
Do you have any mux log?
How is the module connected - via USB or serial. If serial, please verify if you are using power saving on serial interfaces.
Best regards,
Bartłomiej

Hello,
This means that the MUX data Frame is corrupted. This can happen when there is a data lost in the serial interface.
Still I haven't found any record in our databases regarding similar problem and the possible reasons.
