I'm not sure if I set it up here, but I understand the situation.
I will use the uP command to set it to 200Hz.

I'll close this case.
Thanks for the reply.

Thank you to share "pG" command information.

I send pG command for 50Hz and 200Hz IMU.

50Hz
OpenIMU330BI 5020-1800-01 02.01 SN:2074009097

200Hz
OpenIMU330BI 5020-1800-01 02.01 SN:1974001265

Frimware version and Unit model is same, but output rate is different.

uP" command: "55 55 75 50 0C 04 00 00 00 C8 00 00 00 00 00 00 00 F0 D5" ，set ODR 200HZ.
"uP" command feedback "55 55 75 50 04 00 00 00 00 1C 26", it means operation succeeded.
"sC" command "55 55 73 43 00 C8 CB" , save the parameters.

I haven't tried these commands yet. I whill try it later.

First of all, why is the output rate different for the same FW Version?

Thank you for replying.

could you supply current FW version which is used in your current units?

I whill check the firmware version, but I don't know how to do it.
Pls teach me how to check current fw version.

I have already confirmed that the P/N 8350-1800-01 that I bought before has an Output Data Rate of 200Hz UART output.

The one of P/N 8350-1800-02 that I bought recently has only Output Data Rate 50Hz. (UART)

Is there a change in the default firmware that prevents the 200Hz output?

Also, I originally bought it with the expectation that it would output 200Hz, but has the specification been changed?

If you need any additional information, just ask.

Thanks you for reply. I will contact with sales.

I have three questions about the OpenIMU application.

Question 1.
I am planning to buy the production version of OpenIMU330BI instead of DevKit, will it be sold with the application written on it?

Question 2.
Will the application have the latest version at the time of its sale?

Question 3.
On this site.

Update Time: 2019-12-20 09:00:00

Which is listed as the correct one?

And is this app likely to be updated frequently? Is there basically no plan to update it since the quality is already stable?
