Page 4: Introduction
1. Introduction. The Ethernet Adaptor EAD 02 Device Server is designed to connect peripherals with a Serial interface to an Ethernet Network using the TCP/IP protocol family (TCP for Transparent stream and UDP for Datagram applications). Various peripherals can be... -
Page 5: Network Interface
2.3. Hardware Address 2.3.1. Network Hardware Address The hardware address of the EAD 02 can be calculated from the serial number and type: First three bytes are fixed, and read 00-20-4A Fourth byte is the type of the unit: ? 0 2 for EAD 02. -
Page 6: Power Supply
Figure 2 2.4. Power Supply The EAD 02 has In-built Power supply with 230VAC Power Input. Typically, the unit consumes around 250mA with the 10BaseT Ethernet interface activated. 3. Network Protocols The EAD 02 uses TCP/IP protocols for network communication. The supported standards are: ARP, UDP, TCP, ICMP, Telnet, TFTP and SNMP. -
Page 7: Channel Identification
In the EAD 02, a different port number for each channel must be configured. The EAD 02 uses this port number as the source port in outgoing messages and receives connections or UDP datagrams, which are addressed to this number. Port 9999 (decimal) is used for remote configuration. -
Page 8: Factory Ip Address
Ethernet 4.3. Initial IP Address Setting If the IP Address of the EAD 02 is unknown or undefined, the following sets a temporary IP address: a) Set a static ARP with the desired IP address using the hardware address of the EAD 02, which is printed on the product label. -
Page 9: Serial Configuration
EAD 02. The terminal (or PC) should be configured for 9600 Baud, no parity, 8-bit, and 1 or 2 stop bits. To enter configuration mode, the power on the EAD 02 must be cycled (powered off and back on). After power-up, the self-test begins. About a half second later the red LED starts blinking. -
Page 10: Telnet Configuration Password
IP address is used. Appendix B covers the calculation of the right value in detail. The EAD 02 prompts for the number of host bits, and then calculates the netmask. It is shown in standard format “255.255.xxx.xxx” when parameters are displayed. -
Page 11: Flow Control
This parameter defines the port number on the target host to which a connection is attempted. NOTE: To connect an ASCII terminal to a host using a EAD 02 for login purposes, use the remote port number 23 (This is the Internet standard port number for Telnet services). -
Page 12: Connect Mode
4.7.6. Connect Mode This parameter defines how the EAD 02 makes a connection and how it reacts to incoming connections over the network. Function Connection acceptance Never accept incoming Accept incoming with active DTR Only Accept unconditional (if not busy) -
Page 13: Disconnect Mode
Example: The configured remote IP address within the EAD 02 is 129.1.2.3 and the TCP port number is 1234 : C121.2.4.5/1<CR> complete override - connection is started with host 121.2.4.5, port 1. C5<CR> This means connect to 129.1.2.5, port 1234. -
Page 14: Inactivity Timeout
If Bit 5 is not set, any other characters already in the serial buffer will be included in the transmission after a “transmit” condition is found. If the bit is set, the EAD 02 will immediately send after recognizing the transmit condition (sendchar or timeout) NOTE: A transmission might occur if status information has to be exchanged or an acknowledgement has to be sent. -
Page 15: Telnet Terminal Type
Only one name can be entered. If Terminal type option is enabled, EAD 02 also reacts to the EOR (end of record) and binary options, which can be used for applications like terminal emulation to IBM hosts (contact Lantronix for details). -
Page 16: Configuring Through Telnet Connection
To configure the unit over the Local Are Network, establish a Telnet connection to port 9999. From the Windows Start menu, click Run and type the following command, where x.x.x.x is the IP address and 9999 is the EAD 02’s fixed network configuration port number. telnet x.x.x.x 9999 (Example: telnet 192.168.100.123 9999) Note: Be sure to include a space between the IP address and 9999. -
Page 17: Line Interface Description
The following paragraph addresses the standard EAD 02. The serial interface of the EAD 02 is designed to be used like a standard DCE (data communications equipment) modem. EAD 02 transmits data received from the network to RxD (pin 3) and sends data received on TxD (pin 2) to the network. -
Page 18: Secondary Rs-232C Interface
EAD 02. The signal goes low if the printer is unable to accept more data (e.g. the printer buffer is full). It must be connected to the EAD 02’ RTS input. Depending on the model,... -
Page 19: Software Handshake
If a DTE (printer) has a “ready”- signal (paper installed etc.), it can be used to deny the connection if not ready. In this case, this signal must be connected to the EAD 02 DTR signal, and the connection setup should be set to “accept only with active DTR”. -

Page 22: Appendix A
Appendix A - IP Addresses, Netmask etc. A.1. IP Addressing An IP address is a 32-bit value, divided into four octets of eight bits each. The standard representation is four decimal numbers (in the range of 0..255), divided by dots. Example: 192.2.1.123 This is called decimal-dot notation. -
Page 23: Broadcast Address
A.6. Broadcast Address The address with the host part bits set to ‘1” is the broadcast address, meaning “for every station”. Network and Broadcast addresses must not be used as a host address (e.g. 192.168.0.0 identifies the entire network, 192.168.0.255 identifies the broadcast address). -
