Batboard

Hello. I have a couple of questions in regards to XTVA units for XTS 5000 radios. We are set to install several in a mobile command post that we will be receiving in the near future but I would like to make them as “flexible” as possible. My question is whether or not the unit can accept various accessories such as a foot petal remote PTT, a noise cancelling headset/microphone combination and a Motorola desktop microphone? My second question is if these units to not readily accept such accessories, can they be made to accept these buy simple engineering? I understand that on the DB-25 J% connector that position pin 19 controls an external ptt and that pin 9 controls and external microphone so I am wondering if with some basic electronics information, can these items be made to work?

Any assistance would be greatly appreciated.
