Set ID and password used for PPPoE. EZL-200L uses maximum 32 byte for saving an ID and 8 bytes for a password. ezTCP provides User Authentication function to prevent an unwanted person from modifying the configuration. The authentication process is performed through the password string verification.
currently searched ezTCP. This is only supported over ezConfig version 4.3c and ezVSP version 2.2h. Exit program. 3.2.2. Example configuration of ezConfig (LOCAL) ezConfig can be used to change the IP address related items, the serial port setup value, the serial port operation mode. This section describes these functions briefly. For more information, see the following sections.

Set [ezTCP Mode], [Local IP Address], [Local Port], and serial port related items. After setting press [Write] button. If there is any error during writing process, check the LAN between PC and EZL-200L. Check if the set IP address is correct with ping command in DOS prompt.
<When IP address is a.b.c.d.> √ IP address, subnet mask, and gateway IP address of both PC and EZL-200L should be correct to succeed in ping test. 3.2.3. Example configuration of ezConfig (REMOTE) Input the IP address of EZL-200L in IP address field in the [REMOTE] tab, and press [Read] button.
Network Scan mode. After then, press the button again and keep the state over 10 seconds. If the Status LED blinks once at a second, it means EZL-200L had been reset and the environment parameters of EZL-200L had been initialized.
For more information, see “5. Normal Communication Mode”. 4.2.2. How to Initiate ISP Mode Supply power to EZL-200L with pressing the ISP button on the back of the product, or continue to press the ISP button during Normal mode. Then EZL-200L operates in ISP mode .
4.3. Normal Communication Mode Normal communication mode is suitable for the purpose of using EZL-200L. Normal communication mode can be classified into four modes – T2S, ATC, COD, and U2S – each of which is described in the following table.

After completion, a message that informs the firmware was downloaded successfully. And EZL-200L reboots automatically and run in Normal Mode. In Normal Mode, STS LED is blinked every 1 second. After completion download, reset EZL-200L. - 29 -...
(Data coming to the serial port before TCP connection is established will be ignored.) To limit the peer host, user should set [Allowed IP Address]. The only pre-defined host can be accessible. If [Allowed IP Address] is 0.0.0.0, any host can connect to EZL-200L. - 30 -...

Set the following for T2S mode: Item Description Local IP Address IP address of EZL-200L Subnet Mask Subnet Mask Gateway IP address of Gateway IP Address Relate Address Items Port number for waiting to be Local Port connected Allowed Allowed host to connect Address (if set to 0.0.0.0, any host can connect)
5.2. In ATC mode, the user can control the EZL-200L 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-200L functions as a client. When data of the pre-specified size [Conn. Byte] comes to the serial port, the EZL-200L attempts a TCP connection to the TCP port [Peer Port] of the preset host IP [Peer IP Address].

5.4. U2S - UDP U2S mode allows for UDP communication. In UDP mode, data are transmitted in blocks, which requires dividing data coming to the serial port into blocks before transmitting data. A procedure for dividing data into blocks is as follows: If data of pre-specified bytes [Block] comes to the serial port of the ezTCP or if a specified period of time [Interval] elapses after first data reception, all data received for the same period is recognized as one block which is then transmitted to the UDP.
Page 37
Method Password In addition, if you set the peer IP address and peer port to 0, EZL-200L automatically use the source IP address and port information in the latest received UDP packet as the peer IP and port. This function is available on 1.2A or subsequently released firmware version.
6. ATC Mode 6.1. Overview EZL-200L 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-200L communicates several hosts alternatively.
