Hi, I'm having some issues with the DA1 and Penmap. When I connect the battery to the system (as per the recommended steps) it charges the tablet and works for a few minutes, then Penmap stops working and an error stating the connection to the antenna has been lost. If I then shut down penmap and try and reconnect, I will work, but no power draw will be made from the battery. This is a little frustrating as the end result is a short usage window as the battery isn't being utilised.
I don't know if this is a hardware issue or a software issue, so any help would be appreciated.
