CHAPTER FOUR – 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.
