IONI's Baudrate setting

Questions
1

I am rather lost and frankly concerned about the IONI baudrate (or bitrate).
The default baudrate is 460 800 bit/s.
On the other side, Windows reports the baudrate of my USB-SMV2 adapter to be 9600 bit/s.
In Granity, I cannot see any baudrate setting.

My problem is that, in some circonstances, we need to convert the RS485 “bus” (actually, this will be a point-to-point connection, without anything else than a PC and a IONI) to RS232 voltages. The interface I had envisioned is limited to 250 kbit/s… well, I may find another one. More critical, not all RS232 ports on PCs can handle 460 kbit/s.

On the production line, or on a maintenance operation, we shall be able to change the servo-driver (containing the IONI) and let the PC download all configuration data, and (re-)start operation ASAP.

If I change the IONI baudrate over the API, will this setting be remembered in the non-volatile memory ? Having IONIs ready with a slower baudrate may be an option; but then how could they communicate with Granity or any other software through a USB-SMV2 adapter ?

I am concerned that, under some combination of (adverse) circumstances, we have “bricked” IONIs that can be no more talked to :thinking:

no; it will always be 460800 baud at device power-on.

Not such great news. Thanks anyway.

The baudrate on the USB adapters is typically virtualized and they will actually work at any baudrate the app requests. The driver setting is not actually relevant. Or at least this is how I’ve understood how the FTDI driver works - if a PC app requests a port open with certain baudrate, it will be always done like that, regardless of the setting in the control panel. The baudrate only must be generally supported by the adapter.
