Introduction
Forward WatchDog Box is a device intended for the monitoring
of hardware-software systems based on the FD300 board (the
workability of the operating system, FD300 board, broadcastserver). The device is an external block with a USB connection.
The device provides solving the problems of reserving the auto-
matic broadcasting systems based on the FD300 board.
In case the main broadcast server fails (the FDOnAir applica-
tion or OS hang-up/failure), the device provides automatically
switching to the input passthrough signal or a reserve server
working concurrently with the main one. There are several
reserve schemes.

Reserve Schemes
There are several reserve schemes: bypass, mirroring, mirroring
with bypass.
1. Bypass
Provides switching to the passthrough signal in case of prob-
lems on the broadcast server.
Server is the Forward broadcast automation server.
Commutator is the 2->1 video/audio signals switch; purchased
separately.
MD is Forward WatchDog Box monitoring device for moni-
toring of the video server (workability of the operating system,
FD300 board, broadcast server). The device regularly receives
messages from the server through the USB interface. Failing
messages during a certain interval, switches the commutator to
the reserve.
2. Mirroring
Provides switching to the reserve server in case of problems on
the broadcast server.

3. Mirroring with Bypass
In case of problems on the broadcast server, provides switching
to the reserve server; there being a failure of the reserve server,
switches to the passthrough signal.
Note: For mirroring, you need to purchase a second video server iden-
tical to the rst one. The mirroring process is implemented by a
built-in to FDOnAir (the basic broadcast program of the For-
ward software package) mechanism of transferring messages
to other instances of the program. All the operations (loading
the schedule, starting titles, video data, and so on) performed
on the rst machine are automatically executed on the mirrormachine. The schedules on both servers automatically concur,
for which all the source materials (video clips, titles, etc.) must
have the same full paths. To achieve that, store the data on
the same logical drives (e.g., D) in the folders with the same
name; the le names must also coincide. The materials can be
stored on an external le server. For that, assign the same let-
ter (e.g., V:) on both broadcast servers for the network drive
containing the source materials on the le server. Files are not
automatically copied to the mirrored servers. It is recommended
to use the CopyDR utility (coping les with a specied maximal
data rate) from the Forward T software package.
