Tricaster not communicating with Robyhead D1.

We have notice that once we brought the Panasonic controller AW-RP50 online in the same network (with Robyhead D1 units configured in it) the Tricaster TC1 started communication with Robyhead D1.
Since we removed the AW-RP50 from the network , Tricaster was communicating with Robyhead D1 for a while.
But after power recycle , they stopped communicating.
Now we can control the Panasonic UB300 Camera(Zoom/Focus) from Tricaster, but not Pan/tilt since Robyhead D1 is not communicating.

If anyone has similar setup , please share your experience .
