Summary
2003T is an embedded module that connects Ethernet (TCP/IP) through serial port (TTL level UART). You can transparently convert the serial data to the TCP/UDP data. It adopts the latest generation of ZLAN1003 single-chip solution of Shanghai ZLAN, it has many functions such as: 100 TCP connection, DNS, DHCP, web custom download and so on. The inside of 2003B module has integrated network transformer, the Ethernet pin directly connecting network cable can be ok. In addition, the default power supply of 2003B is 3.3v, can also provide 5V module.
Compared with 2003T, both are designed with ZLAN1003 single chip, but 2003T is larger and has more extendable pins. The operation temperature of 2003T is lower than that of 2003T.
Compared with ZLSN2002, the two use the same pin distribution, but the 2003T has more functions, including web page download, program upgrade via Ethernet port, etc. It can be used for upgrading ZLSN2002.
Features
- Support online upgrade firmware program to install specific features via network, users can get software upgrade tools and upgrade firmware from ZLAN company, and then can upgrade to the highest version.
- Using the configured ZLVircom tool can search, manage ZLSN2003B module on the LAN (support cross-network search) and on the Internet. All parameters of the module can be one-touch configured. Device configuration, management is very convenient. It can use the serial port of ZLSN2003B to configure all its parameters, the command format similar to the AT command, and can directly control, read its running status.
- Support DHCP function, you can dynamically get IP assigned by the DHCP server in the LAN.
- Support DNS, automatically resolve the destination domain name as IP, the destination IP can be the dynamic domain name.
- As TCP Server, support the unique powerful connectivity of 100 connections.
- As a TCP client, support the connection with eight target servers. As a TCP client, you can automatically reconnect after a wire break. Support implied heartbeat technology to ensure the resumption after the network disconnection.
- Support UDP, UDP multicast and other functions.
- Data bits support 5 to 9 bits, parity bit can be five ways: None, Odd, Even, Mark, Space. Support CTS / RTS, DSR / DTR, XON / XOFF flow control, 1 ~ 2 stop bit.
