Identifiying unique roboteq controllers

I\'m going to have 3 controllers total, and was planning to use usb serial interface, is there a way to query a serial number or something? I know I could query the device type, but that\'s not enough. I have 1 HDC2450 and 2 HDC2450S\'s, so I could identify the HDC2450, but not between the hdc2450s\'s. I should be able to figure out which USB is connected, but i\'d like to be extra sure, and I was just hoping there was a serial number or something to query. I can\'t find anything like that in the documentation.

The usb/serial interface doesn\'t seem to have a serial number either.

Since I can identify the HDC2450 dual channel, if I just put the 2 HDC2450S\'s on different USB bus\'s that would be easy to figure out pro grammatically, but i\'d rather have a solution that wouldn\'t matter if I re-do all the USB connection order, for whatever reason, and that would query and determine which USB channel was which.

Thanks,

Controllers dont have a unique id but you can use the \"controller address\" parameter to store any 16-bit value you want.

YOu will need to do this separately for each controller initially using the console and the following command:

^cad nn (nn is the address value)
%eesav (to permanently save the value in eeprom)

Then after you have all controller hooked up on the usb, query that number with the ~cad command.

Perfect, thank you.
