Giving MDC1460 controllers unique address'

I have a robot with 4 MDC1460's on board. We're using the USB connections. I noticed this topic: dev.roboteq.com/dev1/index.php/forum/14-...-roboteq-controllers

However, ^cad and ~cad does not work with my devices and I couldn't find an equivalent command in the manual. Is there another way to give each controller a different address?

Thanks.

Thanks for the response.

I changed the NodeID with ^CNOD and confirmed the change with ~CNOD. However, the USB device ID for all of the devices is still: usb-Roboteq_Motor_Controller_MDC14XX-if00.

We're using a ROS launch file that accesses the serial port via by-id. With FTDI serial devices, each device has a unique ID that we reference with udev rules.

Is there some way that I can change the ID or uniquely identify the motorcontroller, through the serial port, besides the by-path method (which changes when we plug them into different ports)?

Thanks.

Helpful post, thanks.
