A.1.5 CONNECT A SUPPORTED EXTERNAL CONTROL SURFACE?
Connect the USB cable from the Control Surface to one of TriCaster’s USB ports.
SUPPLEMENTARY QUESTION:
Q: TriCaster TCXD850 CS has suddenly stopped working. What can I do?
A: The foremost reason this might happen is if the cable (or extender cable) you are using
between the control surface and the TriCaster failed to deliver sufficient current consistently. In
the short term (if you are in the middle of a show), you can generally resolve this issue by simply
unplugging and re-plugging the control surface.
However, please note that the use of so-called "USB extenders" is not recommended. Whenever
possible, use a single USB cable of the correct length. Each added connector on the signal path is
a potential connection problem, and also causes signal ‘reflections’. Such an arrangement may
seem to work for a while, then fail unpredictably.
If you are using a very long USB cable (or a poor quality cable), you should supply a powered hub
at the end of the cable nearest the control surface, then complete the connection with a short
USB cable from the hub to TriCaster TCXD850 CS. (An unpowered hub will be of no help.)
