PDM support with A2B bus analyzer

Question

Hey, 
 I recently got one of the a2b bus analyzer and am trying to emulate ad2427 on it. 
 Background: We have a chain of mics that are currently running with ad2428 as a main node and ad2427 as downstream microphones connected on PDM0 sending data upstream. 
 Modification: Replaced the downstream bus node closest to the host node with the ADI a2b bus analyzer and am trying to emulate it while also feeding in different tones. 
 Issue: 
 
 As soon as discovery is complete I see the following error/warning pop up on screen. 
 My stream is set up so that each node adds 1 to upstream slots to put it's own mic data. 
 
 This is evident with the slot config 
 But when i go into the audio tab I do not see a source stream available to emulate sending any audio.

Could you help me figure out if I'm doing something wrong or if this is even supported ? All other streams still work fine and the entire setup without the bus analyzer and just the mics also functions properly.

Reply received from ADI - hope it's okay but posting it here incase it would help someone else as well. 
 A2B Analyzer hardware doesn't have PDM Mics inside the Box, So we are not supporting the PDM configuration on the Analyzer when used as an Emulator, and in the A2B Analyzer software it will give an error as posted. 
 Our recommendation is to record the MIC audio into the WAV file by using the tools Audacity/Repear and use wav file to play it on the TDM channels. Need to change the Configuration on the sub-node(Remove the PDM and add it as a TDM channel) and use the A2B Analyzer as an Emulator.)
