A.2 States of an External Device
An externally connected device can go into different states that are all
shown in the State field of the control area in its RS-422 mode. With
the RS-422 mode you can control an external device via the remote
output of the DVS system, such as telecines, VTRs or digital disk record-
ers. Then the I/O Tool will show you the following states of the device:
Additionally (exception: -- Offline --), error messages can be added to
the states detailed above, for example, -- Stop TapeTrouble --. The fol-
lowing error messages can be added:
If the external device is controlled from its own operation panel, all
RS-422 commands are ignored. Then the I/O Tool shows the respective
state with an added ’Local’, for example, -- Stop Local --.
-- Offline -- No external device connected
-- Still -- Tape has stopped but is still threaded with the
video drum head turning (standby on)
-- Stop -- Tape has stopped and is unthreaded, the video
drum head has stopped as well (standby off)
-- Eject -- Device is ejecting the tape
-- Rewind -- Tape is rewound

-- Record -- Device is recording
-- Play -- Device is playing out
