1.3.4. Network Interface EZL-410 senses the network speed (100M bps or 10M bps). And it senses 1:1 Ethernet cable and cross over cable automatically (auto MDI/MDIX). EZL-410 requires simple circuit for Ethernet interface. Refer to 1.3.3. All Ethernet devices have its hardware address (MAC address). EZL-410 also has a hardware address.
IP address environment (local IP, subnet mask, gateway, etc.) Serial port type of the equipment to which EZL-410 is going to be connected (RS232) Serial port items of the equipment to which EZL-410 is going to be connected (baud rate, data bit, parity, stop bit) ...
OK. 2.2.3. Connecting to Serial Port of PC Connect the EZL-410 with the PC through the RS232 cable. And run a serial communication utility – for example: Hyper Terminal or Tera Term Pro. And set the configuration of the utility to [19200bps, 8 data bits, 1 stop bit, no flow-control] as same as configuration values of EZL-410.
2.2.4. Communication Test When the preparation for serial communication is finished, enter the following in the DOS window on your PC, to connect to TCP through Telnet program. "Telnet 10.1.0.1 1470" Enter “123” on the Telnet window, and "123" will appear on the serial communication utility.
The LOCAL SEARCH method use UDP local broadcast with MAC address. So its benefit is that user can search EZL-410 although the user doesn‟t know the IP address of EZL-410. For LOCAL SEARCH, user should select [LOCAL] radio button and press [Search EZL-400 Series].
It is impossible to search EZL-410 outside of the network (router). 3.1.2. Remote Search The REMOTE SEARCH method searches EZL-410 with the IP address. The [Remote Search] item should be activated for this method. For the REMOTE SEARCH, user should select the [REMOTE] radio button in the initial window and input an IP address and press [Search EZL-400 Series], then the ezcfgmp searches EZL-410 with the IP address.
The found EZL-410 is appeared in the [Search List] window. If the user double-clicks the IP address or presses [Read] button, the main window is appeared. When it doesn‟t work because of firewall, the user should open UDP 50005 port, because the REMOTE SEARCH of the ezcfgmp uses UDP 50005 port.
The following is the main window of the ezcfgmp. User can configure the EZL-410 in the main window more easily. MAC Address It is the MAC address of EZL-410. This value is set in the factory and it cannot be altered. Unique IP Address EZL-410 can use one IP address for four COM ports or the IP addresses can be set to each COM ports differently.

Password Password is used for that user configures EZL-410 with ezcfgmp or logins via telnet client. If EZL-410 is set with a password, user should input the password in this item to configure the EZL-410. For changing the password, use [Change PWD].

This option is for setting the communication mode of EZL-410 among T2S, ATC, COD, and U2S. Local IP Address If EZL-410 is set as multi IP address, this item is for the IP address of each COM ports. Each IP addresses should be in a same subnet. Local Port It defines local ports of each COM ports.
Page 21
Water Mark It defines a point of time to start connection when EZL-410 operates as COD. EZL-410 starts to connect to the host (Peer IP Address and Peer Port) of the designated host upon receiving as many data as specified by [Water Mark] bytes from the serial port.
Write User can write the setting values to EZL-410 with this button. Close User can close main window of ezcfgmp. 3.2. Configuration by Console 3.2.1. Entering the Console of EZL-410 There are two methods to enter the console of EZL-410.
3.2.2. Menu Structure The commands to set the environmental variables of EZL-410 in Console Mode are „env config‟ and „env ext‟. If user inputs „env config‟ in the Console Mode, the following will be shown. Its structure is followed: 0. exit 1.
Page 24
COD DELAY EZL-410 connects to the server as soon as it powers on if the [Water Mark] is 0. After disconnecting the connection, EZL-410 will reconnect 10 second later. To change reconnection time, use this parameter (unit: second)
For more information about Normal Communication Mode, refer to next chapter. 4.2. ISP Mode The ISP Mode is that user download EZL-410‟s firmware via the COM1 port. The settings of COM1 port in the ISP Mode are followed: Baud Rate 115200 bps...

The following is firmware download sequence: Reset or Power on EZL-410 after pulling down ISP pin (JP1 #4), then EZL- 410 operates as ISP mode. When it enters ISP mode, the following message is shown. Input „p‟ that is download command, then some messages are shown as followed: ...
Page 27
After firmware download is completed, EZL-410 checks its CRC. If there‟s no error, EZL-410 save the firmware its flash memory. And then it outputs the following messages. After completing firmware download, pull up or open the ISP# pin. And reset or reconnect its power.
If [Timeout] is set, EZL-410 terminates the connection if there is no data transmission for pre-defined time ([Timeout] sec). If [Timeout] is set to 0, EZL-410 sends a Keep- Alive packet every 10 seconds. If there is no response 4 consecutive times from the foreign host, EZL-410 terminates the connection.
5.2. In ATC mode, the user can control the EZL-410 in a similar way to controlling the modem using AT command. In ATC mode, only a TCP connection is possible and both the server and the client can be configured.
In COD mode, the EZL-410 functions as a client. When data of the pre-specified size [Water Mark] comes to the serial port, the EZL-410 attempts a TCP connection to the TCP port [Peer Port] of the preset host IP [Peer IP Address].
A procedure for dividing data into blocks is as follows: If data of pre-specified bytes [Water Mark] comes to the serial port of the EZL-410 or if a specified period of time [Timeout] elapses after first data reception, all data received for the same period is recognized as one block which is then transmitted to the UDP.
6. ATC Mode 6.1. Overview EZL-410 can be controlled by AT commands in ATC mode. For example, the peer host IP address can be set by AT+PRIP command and connect to the host by ATD command. Therefore, EZL-410 communicates several hosts alternatively.
To change On-line State to Command State during the connection, +++ string should be transmitted to EZL-410 as following sequence. When transmitting +++ string to EZL-410, +++ string will be sent to peer host. The time from final data the first „+‟ data of No data over 500ms(guard time) „+++‟...
