D-3 Custom Ethernet Link
By default, the V440-F reader operates as a server, and communicates with the host over TCP/IP for
both commands and data.
Custom Ethernet Link
functionality gives you the ability to create an Ethernet interface that is bound to
the command processor per your own requirements. You can set the
Transport Layer
to
UDP
or
TCP
,
set the message
Type
to
Server
or
Client
, and set
Capabilities
to
Send Only
,
Receive Only
, or
Send/Receive
.
Custom Ethernet Link is intended for advanced users. This feature permits the establishment of a
connection to the reader on any port, using the protocols UDP/IP, TCP, and Multicast on a specified
port. A bi-directional communication configuration is available to send commands to the reader, obtain
barcode output data, or form a single direction of communication, i.e. sending commands to the reader
only, or receiving barcode data from reader only, without having both directions open.
In addition to the ability to move ports, you can also force the connection created by the Custom
Ethernet Link to act as a client. Instead of "reaching out" to the reader, it is possible to configure the
reader to “go out and connect to” a specified server. This increases flexibility when integrating readers
into customer applications. Without this feature, users are limited to static communication into and out
of the reader – UDP=80, TCP1=2001, TCP2=2003.
The following section will cover the implementation of how the Custom Ethernet Object is implemented
in an Ethernet-based reader. This additional Ethernet-based transport layer allows you to:
•
Send "and/or" commands to the device from a specified endpoint;
•
Send barcode data to a receiving endpoint i.e. a client or server;
•
Handle more than one connecting endpoint connection.
With Custom Ethernet Link functionality, users can configure:
•
Transport Layer;
•
TCP, UDP, or Multicast;
•
Message Type;
•
Server or Client;
•
The type of data sent and/or received from the device;
•
The endpoint to send and receive data, send only barcode data, or receive only commands.
Custom Ethernet Link functionality is bound to the reader's command processor as shown in the figure
below. This enables an outside endpoint to still send commands to the device as well as receive data
commands and barcode to the receiver.
