Chapter 1 TD Bridge Overview

TD Bridge Overview
This chapter provides an overview of TD Bridge and explains the functions. In addition to that, the following information is
provided; system requirements, supported disc types, and system examples using TD Bridge with cooperative applications.
This manual uses“Discproducer” to collectively indicate the PP-100II, PP-100, PP-100AP, PP-100N, PP-50BD and PP-7050BD.
What isTD Bridge?
TD Bridge allows you to interface your system to Discproducer for publishing discs by means of Hot Folder method. TD Bridge
allows you to publish CD/DVD discs with write data/print data or print only.
You need to develop a cooperative application for controlling TD Bridge. Then you can publish CD/DVD discs directly from
your system.
EPSON Total Disk Maker is required for using TD Bridge. For more details on EPSON Total Disc Maker, see Discproducer User's
Guide.
Diagram of Connection
The following shows a diagram of connection in a system that incorporates TD Bridge and a cooperative application.
In this case, the cooperative application is incorporated in an electronic accounting slip system.

TD Bridge and Total Disc Maker are
installed.
(1) The cooperative application sends job description
files (JDF).
(2) TD Bridge creates CD/DVD images and label print
data (images, characters) referring to data as
instructed by JDF (data volume available to be
referred is limited).
(3) Discs are published.

Error handling
When an error occurs while checking the RJD file or writing data to a disc, the RJD file or INP file is changed to ERR (ERRor) file.
The error code is written to the STF file.
When an error occurs while checking the RJD file or writing/printing data to a disc, the RJD file or INP file is changed to ERR
(ERRor) file. The error code is written to the STF file.
In the case of errors during operation, job error information moves to the log folder after one or two hours, and device error
information remains in the STF file unless the reason for the error is removed. (For more details on STF file, see "STF File" on
page 4-72.)
Registering another job during operation
You can register another job during operation. When a JDF file is created and moved to the monitoring folder using the
cooperative application, preprocessing is performed and the JDF file is changed to RJD file. Then when the preprocessing is
completed, the RJD file is changed to INP file and holds the status until the ongoing job is finished.
Upon completion of the ongoing job, the registered job is automatically started.
The discs are published in the order of registration. Setting the job priority enables jobs registered later to be started earlier.

Status Check Method
There are the following three methods to check Discproducer status.
❏Checking the STF file
• See the STF file using the cooperative application.
• This file contains status information on the job and Discproducer, and error code issued by the
cooperative application. We recommend that you use this file for error handling.
❏Checking the JDF file extension
• See the JDF file extension using the cooperative application.
• The status of each job can be checked easily.
• The extension of the JDF file changes according to the operation status. Only by checking the
extension, you can know the status.
❏Checking the EPSON Total Disc Monitor screen on the computer
• Activate EPSON Total Disc Monitor on a computer connected to Discproducer to check the status.
This cannot be automated by the cooperative application.
• EPSON Total Disc Monitor allows you to check status of jobs performed directly by EPSON Total
Disc Maker in addition to jobs using the cooperative application.
• You cannot see the status information over a network.
