INTRODUCTION
22.2 Chapter Issue 1 Sep 02
Establishing a
Network
Connection
The four items that need to be set up to establish a network connection are listed
below:
Protocol Generally, the protocol used is TCP/IP (Transmission Control Protocol/ Internet
Protocol) where communications between computers is divided into packets
with headers (electronic address labels) that identify the IP address. Every IP
Address is divided into the network ID portion (Net id) and a client ID portion
(Host id).
NOTE
DEK can support any protocol that customer has, only TCP/IP needs the
information provided in this chapter, other protocols provide automatic address-
ing techniques.
Physical Establish the cable type, examples are shown.
• 10 Base T (Thin Ethernet)
NOTE
DEK only provide support for the 10 Base T cable types. The plug is an RJ45
type and it is recommended that a CAT 5 twisted pair arrangement is used
(details later in this chapter).
Once this is known the location of the network socket must be assessed and an
assessment made of the suitability of the system for the application.
NOTE
If a customer has a different arrangement to the above, it may be possible to
convert to this arrangement using a different connector. Contact DEK Customer
Support for details.

Registration on the
Server Domain
DEK only support networking on Windows NT Server/Client based archetec-
ture.
The printing machine needs to be registered on the correct domain, this
information 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 22-1 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 infor-
mation 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 a 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
22.4 Chapter Issue 1 Sep 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 custom-
ized to meet the users requirements.
Figure 22-2 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).
Server
Network
Input Conveyor and Printing Machine
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.
