Device number with pololu protocol (ASCII)

Hi, I’m trying to control two 12V DC motors with two different motor controllers (umc03a) with ASCII commands and daisy chaining. I can control one with “F3200\r” command (forward, fullspeed). But cant figure out how to set the device numbers (first motordriver is number 13 and second 12).
Any help would be greatly appreciated.

Hello.

You can set the device number using our Simple Motor Control Center software. You can find more information in the “Serial settings” section of the user’s guide.
