The BBUS Interface at the keyboard end of the link
sends a stop command if the joystick/lens is not
active every 5 seconds. This is used to help with
links that could lose data.
If the link is bi-directional, then the following led flash
sequence will be seen.
1. KEYBOARD END GREEN (data out)
2. MATRIX END YELLOW (data in)
3. MATRIX END GREEN (data out)
4. KEYBOARD END YELLOW (data in)
If the link is a simplex link then just steps 1,2 and 3
will be seen as the data will get back into the
KEYBOARD end interface.
