Yes, the CB200 does support EX bus INPUTS from the RXs .. that's how I normally use it. But (unlike the CB400) it does not have an EX Bus out.[Edit: this is incorrect! see below!].. which is what I could really use .. then I could hang a CB100 off the EX Bus output and get the add'l channels. Esprit has a video of this sort of setup with the CB400 talking to two CB100s, one in each wing, using two of the EX Bus outputs from the CB400.
