If a destination is locked, it will be low-tally red. If you press its button, it will go high-tally
red. You cannot perform a take for a destination that is locked. See
Locks .
Machine Control Takes
The method for performing a machine control take is the same as for any other compact router:
first press a DST button and then a SRC button. However, for machine control routers, the
intrinsic nature of the take is different and the effects on the control panel are different:
1 A machine control router is a point-to-point router whereas other compact routers are X/Y
routers. In an X/Y router, a source can be routed to multiple destinations. In a machine con-
trol router, a new route breaks all previous connections to the source and all previous con-
nections to the destination prior to making the new connection.
2 Port router connections are bidirectional. A port is both an input and an output. Thus, if you
take SRC1 to DST6, SRC6 is also connected to DST1.
For dynamic ports, there is a difference between taking DST 6/SRC 1 and taking DST 1/SRC 6.
DST 1/SRC 6 Port 1 is “controlling.” Port 6 is “controlled.”
DST 6/SRC 1 Port 6 is “controlling.” Port 1 is “controlled.”
Thus, it is the destination that is “controlling.” That is because compact machine control rout-
ers are “data reverse” or “machine control reverse.”
3 Internally, the router can change a dynamic port from controlled to controlling or vice versa.
See Machine Control Routers (page 20) for a description of port types.
 Machine control takes do not start, stop, rewind, or cue any machines, nor do they pre-roll or
position any media.
Locks
The 1RU panel has 6 function buttons. The 2RU panel has 12 function buttons. In all cases, two
of the function buttons are locks, four are level buttons. Any other buttons are reserved for
future use.
 Buttons are not labeled at the factory. You must create your own labels. See Button Legends
on page 74.
Panel Lock
Pressing ‘Panel Lock’ disables the control panel. Only the ‘Panel Lock’ button remains enabled.
Pressing it again re-enables the control panel.
