Registration on the

Server Domain

DEK only support networking on Windows NT Server/Client based architecture.

The printing machine needs to be registered on the correct domain, this informa-

tion is obtained from the network administrator and there may be a requirement

to have a user account set up and a password given. To register the printer select

Control Panel, Network and set the identity and the domain that it uses.

Figure 28-1 Setting the Correct Domain

NOTE

The network administrator is the only person who can supply the information

above. No attempt to make network connection should be made without the

administrators permission to do so.

NOTE

Do not leave the shared name as the default C$ this causes an error condition

Editing each component opens a dialogue that informs the user of what the affect

of each task is. The computer name, workgroup, domain, user name and

password can be set.

Files When communications are established the user can transfer information to and

from folders that reside on the network, the network administrator may wish to

impose restrictions on who can access these files. Sharing and security informa-

tion is obtained and set by right clicking on the required folder in Windows

Explorer, select File, Properties and set permissions, security and sharing

options as required.

NOTE

It is not good practice to set a complete drive in the shared mode as information

is easily deleted or altered accidentally.

Shared folders and files should be created for specific DEK applications eg,

READINGS.DAT, see your application manual for details.

COMMS PROTOCOL OPTIONS

27.4 Technical Reference Manual Chapter Issue 1 Aug 02

COMMS PROTOCOL OPTIONS

These are the only options currently offered by DEK Printing Machines Limited.

GEM This configuration implements the SMEMA standard for communications for

Surface Mount Equipment. GEM (Generic Equipment Model) is a standard sub-

set of the SECSII protocol. GEM is specifically designed for implementing

equipment automation in a production environment.

In this configuration, a host computer running GEM compatible software ‘talks’

to the machine via a Network cable.

If the Host is a PC, DEK’s ‘Software Tools for Productivity’ packages can be

used to modify product files (Off Line Editor) or to control machine operations

remotely (Remote Product Changeover). The Event Log can be read by a text

editor. The flexibility of the GEM interface allows data collection to be

customized to meet the users requirements.

Figure 28-2 Network GEM - Typical Configuration

SDR Driver The IP Address of the printer must be set up in the SDR Driver. To do this edit

the SDR configuration file D:\printer\conf170.cfg using a text editor. Set the

passive IP Address to the printers ‘IP Address’. If there is more than one printer

communicating with GEM Host, the DEVICEID is set different for each printer.

DEVICEID values can be set within thew range 0x000 - 0x7fff (0 to 32767).

Host PC

The system is hosted by a standalone PC connected

to the DEK printer using networked GEM or Net_Files.

A typical system may interface external components

such as a Barcode Reader which uses serial RS 232.

NET_FILES This configuration allows users to redirect files away from the machine’s local

hard drive to a remote directory on a file server. The machine is configured to

access a ‘product’ directory for a product file and a ‘data’ directory to output

data files.

At the machine when a product file is loaded it is read from the ‘product’

directory on the network file server. When it is saved, provided local copies have

been enabled the file is saved to the printer hard drive. If local copies is disabled

then no save is available and any edit is lost. Files cannot be read directly from

the printer or sent to the printer across the network.

Once the files are present on the server, they can be accessed from a networked

PC without interfering with the machine.

Net_Files is used where remote control applications are not needed, at a net-

worked PC, DEK’s Off-line Editor software can be used to modify product files.

QC-Calc software can be used to access SPC data in the ‘READINGS.DEK’ file

and the Event Log can be read with a text editor.

NOTE

To set up a specific software package refer to the product manuals ‘Software

Tools for Productivity’ that are supplied with the application.
