1.4 Advantages
The ZLAN1003 series has four advantages as follows: zero software development,
integrated abundant IOT function, some applications without external MCU, seamless
connection with the original serial port procedures.
1.4.1 Zero software development
Figure 3 ZLAN1003 Application Diagram
ZLAN1003 series chip internal program does not need the user secondary
development, the UART that joint the user MCU directly sends and receives the data
so can transmit data to the computer program on the network. The user use steps
are as follows:
1) ZLAN provides the complete circuit diagram of ZLAN1003 chip. The user is
designed according to this circuit diagram and welding ZLAN1003 to the circuit
board.
2) After ZLAN1003 circuit boards power on, the RJ45 port of circuit board of
access to network, any computer in the network search device through
ZLVircom or user's own development program with network, also can use
ZLVircom to check the IP and port of ZLAN1003, can configure the IP and baud
rate if necessary. Connect the Socket (TCP/IP) software to the device IP and
port.
3) The relevant indicator light indicates whether ZLAN1003 and the computer are

Shanghai ZLAN Information Technology Co., Ltd Tel: [phone] http://www.zlmcu.com
11
establishing TCP/IP.
4) After the connection is established, the data sent to ZLAN1003 by the Socket
(TCP/IP) software will be sent to the user MCU by UART, and the data of the
user MCU can also be sent to the computer Socket (TCP/IP) software through
UART.
5) If necessary, the user MCU can read the MAC of ZLAN1003 and modify the IP
by the AT-like instruction.
There is not a bit of software development in the above steps, and even hardware
development offers a complete circuit diagram. Only need to use ZLVircom configure
the parameters like IP and baud rate in the first time and stored you can directly use,
really achieve the zero software development.
It is generally possible to complete the development of a IoT product based on
Ethernet. This zero software development feature provides a quick solution for the
quick launch of user products, and also avoids problems such as long software
development time and unstable software development.
1.4.2 Integrated rich IOT functionality
ZLAN1003 has already integrated many IOT functional modules, reducing the
workload of user developing related IoT functions. Here are a few typical features:
1) Registration packet and heartbeat package function: when the IoT device joint
with the cloud it need to send its ID to the cloud software to facilitate the device
number. ZLAN1003/1043 has multiple registration packet and heartbeat packet
style.
2) ZLAN1043 can be configured as HTTP mode, which can be directly connected
with the asp/ PHP GET/POST command in the cloud.
3) ZLAN1043 can be configured as a "Transcoding" function, which can
automatically send instructions by serial port, and then upload the instrument

Shanghai ZLAN Information Technology Co., Ltd Tel: [phone] http://www.zlmcu.com
12
data in a customized format. It is convenient to convert different devices into a
unified cloud server format without secondary development.
4) With Modbus gateway function and Modbus TCP to Modbus RTU;
5) ZLAN1043N supports cross-intranet communication in P2P way, and realizes
access to Internet via ID anytime and anywhere; it can realize PC monitoring of
any intranet device in the environment without cloud.
1.4.3 Some applications require no external MCU.
Because ZLAN1003 chip no need to configure MCU through serial port and SPI, the
internal solidified program already can realize UART to TCP/IP, and the ZLAN1043
has powerful "Transcoding" programming function, so users can ignore MCU, this
can reduce circuit complexity and save cost.
We list the following situations:
1) Connect the wireless serial port module: ZLAN1003 can be used as the
gateway of some wireless module data acquisition to TCP/IP. At one end of the
gateway are wireless modules, such as bluetooth, Zigbee, Rola and other
UART interface modules, and Ethernet at the other end. At this time, only the
UART of ZLAN1003 and the UART of the wireless module can be directly
connected, no additional MCU is needed.
Figure 4 Joint Wireless Modules
2) Instrument acquisition: ZLAN1043 supports the powerful "Transcoding" function,
which has automatic collection, and can be programmed with the data in the
custom format. At this time as long as the transcoding configuration file is

Shanghai ZLAN Information Technology Co., Ltd Tel: [phone] http://www.zlmcu.com
13
written to ZLAN1043 inside, then ZLAN1043 will send specific instructions, and
sent to the cloud according to the fixed format, need to add a MCU for data
acquisition and protocol conversion on printed circuit board.
Figure 5 Instrument Collection
3) Serial port to Ethernet port gateway: ZLAN1003 itself is a powerful single chip of
serial device server, if you need to implement serial port to Ethernet port
gateway function, need to add external MCU, also without software
development. In addition, ZLAN1003 has RS485EN pin, which can support all
kinds of 485 chips.
1.4.4 Seamless connection with the original serial port procedures.
Figure 6 No Modification for User MCU Serial Port Program
Many RS232/RS485 devices have UART interfaces inside the original MCU, and the
internal procedures of MCU have been developed. For the following reasons, users
may not wish to redevelop the internal procedures of MCU:
1) The MCU serial port program has been verified for many years and is stable
and reliable. If redevelop it to interface such as SPI, there will be stability
considerations.

Shanghai ZLAN Information Technology Co., Ltd Tel: [phone] http://www.zlmcu.com
14
2) Due to short R&D schedule and insufficient R&D resources, directly using the
original MUC program will accelerate the progress and reduce the R&D
investment.
3) The original MCU program code has been lost or is not maintained by the
technician.
ZLAN1003 provides a good solution for the network upgrade of such RS485/232
devices, so long as joint the part that joint with 232/485 chip before to ZLAN1003.
There is no need for software development, just design the circuit to complete the
product upgrade.
ZLVircom is equipped with the virtual serial port function. If the user does not want to
modify serial port software of the upper computer, it can also meet the requirements.
