2.1.2 Ethernet Protocol
In the current implementation, TCP/IP is used as the transport protocol. TCP is a connection-oriented protocol
that provides a reliable, in-order data transport layer with end-to-end checksums and flow control.
2.1.2.1 TCP Connection Setup and Teardown
A session between client software and the reader consists of connection setup, data transactions, and
connection teardown.
At present, all connections are initiated only by the client software. If, for example, the reader is configured to
automatically forward events and/or data to the client software but the client software has not established a
connection, then no attempt is made by the reader to contact the client software to establish a connection.
Furthermore, if an extant connection terminates unexpectedly, the reader will not attempt to contact the client
software to re-establish a connection. All responsibility for opening, maintaining, and closing the connection
during a session rests with client software.
The client software sets up a TCP socket connection on reader port 7090. After connecting successfully,
communication between the client software and the reader can proceed as described below. Once the client
software has determined that communication has concluded, the connection must be terminated at the TCP
level. In order to prevent synchronization issues, each reader will support only one TCP connection.
Other transport protocols may be used to communicate between the client software and its subjugate readers.
The application-level protocol discussed below is neutral with respect to the transport layer.
2.1.2.2 Reader Configuration
In some cases, the application software may provide support for reader configuration. If so, follow the
instructions provided with the application.
The following procedure describes how to configure the reader directly from a network PC using the browser-
based interface.
The reader is with a static IP address which is default setting '192.168.1.200'. At first you can connect to the
reader using the default IP address and change IP address to adjust it to your network environment.
Default network setting:
IP Address: 192.168.1.200
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.254
If you are not using DHCP, you must know the IP address and subnet mask settings for the network
environment in which the reader will be running. If you are using DHCP, you must have a means of finding the
reader, typically by having a DHCP server update a DNS server.
How to change network settings is as the following:
1. Exit any reader applications that are running on the network.
IMPORTANT: Running another reader application while using the browser-based interface may cause a
reader error. If this happens, reboot the reader or restart the system using the browser-based interface.
2. Verify that the reader is operational. All LED’s should be out except for the green power LED which should
be pulsing.
3. Start a Java-enabled web browser from any network-enabled PC. This PC must be configured with an IP
address and subnet mask compatible with the reader’s settings. For example:
