HyperDeck Control

My Name is Matt Gililland and I am a Control Systems Programmer in Houston. I was recently given the task of controlling a BlackMagic HyperDeck via TCP/IP using a QSC Qsys control system. I went over the protocol, made sure my sockets and ports were correct, and attempted to connect TCP/IP to port 9993. I got a response when the socket connected of 500 and the name of the unit, but after that, i got no control or any response at all, including unsolicited responses from pressing the buttons on the unit. I then connected using PuTTy to the same IP and port and it worked right away, the unit controlled and responded commands and gave unsolicited feedback. Beyond the control that is laid out in the manual are there any other negotiation factors in play that I need to know about? I am really stuck on this one.
