T3-22i baud rate register

I’m using a T3-22ai in a solution with other devices. One of the other devices is fixed at 9600 baud. Looking at the register database for the T3-22ai, I don’t see a register for baud rate. I have my own commissioning tool, and I just need to know what register to use to adjust the baud rate on this device

On the T3-22AI, the baud rate setting is stored in Modbus register 15. You can write one of the following values to this register to set the desired baud rate:
0 = 9600
1 = 19200
2 = 38400
3 = 57600
4 = 115200
5 = 76800
