CHAPTER FIVE – D-NET File Transfer Operations
Introduction
D-NET is a new kind of audio network designed by 360 Systems. It uses Instant Replay's digital
audio interfaces for high-speed audio transfers, and to backup and restore files for archival
purposes. Unlike other networking schemes, there is no extra cost for networking cards or
hardware, no special software, and it is compatible with other products such as routers and
distribution systems that use the AES/EBU digital audio interface standard. It can also use the
coaxial connection (AES/SMPTE 75
Ω
) which is compatible with 75
Ω
video equipment.
Features
•
Transfer individual audio Cuts, or the contents of entire drives, from one Instant Replay to
another.
•
Transfer to and from DigiCart/II hard disk recorders. (Note: the DigiCart/II machines must
have the file transfer option installed. DigiCart/II Plus includes file transfer as standard.)
•
Backup and restore a bank of files, or an entire drive, to an AES/EBU equipped DAT
recorder.
•
Transfers file headers with File Name, Index Number, running time, etc.
•
Transfers audio faster than standard playback rates.
•
Supports AES/EBU and AES/SMPTE-75
Ω
digital interfaces.
•
Individual machines can be configured to allow or disallow automatic reception of transfers.
•
Optional protection for overwrite of existing drive contents (via the 'Mail Box' feature).
File Transfer Characteristics
Transfers are one-way, without acknowledgment from the receiver, and are initiated from the
sending machine. The sender specifies a destination name, or partial name with a wild card
character. All machines that are configured with a matching name can receive the file.
A file is transferred to a specific Cut Index, or optionally to a 'Mail Box' location. A transfer to a
specific disk location will replace an existing file if one exists at that location. A file transferred
to the Mail Box will be placed in the next available Index Number in the destination machine.
Each receiving machine can be configured to disallow transfers to specific Cut locations.
All machines to receive a transfer must be enabled to receive file transfers, must be configured
with a name matching the name specified by the transfer, and must not be playing or recording.
Receivers offer the option of a "blank receiver name" which matches all names, and thus receives
all transfers.
The destination machine will discard files received with errors. Since files received with errors
are discarded the user does not get a direct indication of which files in a multiple-file transfer
need to be re-sent.
An operator at a receiving or sending machine can easily cancel file reception to regain control of
the machine at any time by pressing the S
TOP or C ANCEL buttons. The user is prompted to
confirm before the transfer is aborted.
Only one sender can be transferring files at a time.
