BL2500 Models & Cables

Hey guys,

   I'm using few BL2500, I've been told they are all the same, but as I can see in Dynamic C there is different models (29Mhz / 44Mhz, 256k - 512k RAM/FLASH).

I also have 2 different connectors. Blue Shrink and a Red one. The Blue connector is smaller tho.

Can anyone help me through this ? How can I know what type of BL2500 I am using.

And what’s the difference between the 2 cables.
