Roger 15 Receiver & Roger Pen Connectivity

Asking for help with my Target Software and Roger accessories configuration. The pen WILL connect with the Roger 15, but I get no sound from the pen. Instructions for the Receiver say to ensure that the Q90 is configured like this: Roger /FM/DAI/EXT/AUX I am using the latest Target software, but I do not see that option anywhere. The Receiver and the Pen are selected as accessories for the Q90 and their S/N are entered. Note, although the Pen flashes green to show it’s connected, I do not get any sound from/through the pen. Any ideas anyone ?? THANK YOU !! :confused:
