Replacing IT-100 with AD2SER

I am a Crestron programmer and am looking for a replacement solution for the DSC IT-100. How does the AD2SER compare with the IT-100 in terms of capability and reliability?
Does the AD2SER support DSC 1832 and 1865 panels?
Is the AD2SER required to be assigned on the keybus?
Is it able to received broadcasted zone labels?
Can we go into programming mode with the AD2SER?
