summarize

ZLSN7004 is a High-performance Wifi, Ethernet to serial port module developed by Shanghai ZLAN. Unlike the ordinary wifi module, which is positioned at low cost, the 7004 is positioned at high stability and rich functions, and the design goal is to face the industrial field with high requirements for function and stability.

7004 continues Shanghai ZLAN's more than 10 years of product design experience and software technology accumulation in the field of TCP/IP to serial port. The software system is similar to ZLSN2002 Ethernet to serial port products, and has the same stability and rich functions as ZLSN2002.

7004 adopts 11 +12 double row pin structure, compatible with ZLSN2002, voltage supply is 3.3V. The serial port is connected to the TTL level serial port of the user device through the RXD, TXD, and GND of the 3-pin UART, and the other end is connected through wifi or Ethernet. wifi supports STA mode to connect to a wireless router, or AP mode to allow wifi devices such as mobile phones to connect. The module does not contain a network transformer, and the user can use the RJ45 containing the network transformer to connect directly with the Ethernet interface of the module.

ZLSN7004 can be used in security monitoring, smart grid, factory automation, energy environment detection, intelligent transportation, smart home and other fields. Instantly upgrade your system from serial to WIFI.

peculiarity

  • Support Ethernet and Wifi access simultaneously.
  • Internal integrated real-time operating system, fast startup speed.
  • Serial port has real-time response speed. The data packet frame interval is adjustable from 1 to 255ms. Similar wifi modules can only reach a minimum of 20ms or 100ms framing capability, 7004 can reach 1ms real-time frame performance.
  • One-click search configuration. When you forget the SSID or password wifi can not find the module, just plug in the network cable even if not in the same network segment, using ZLVircom tool can immediately find the module and configure wifi, network, serial port parameters. In addition, you can configure parameters in Web mode.
  • Provides a reset button. You can reset the wifi parameters and IP address of the module.
  • Wifi Supports wifi connection between modules.
  • provides 485_TEN pin for easy connection with RS485 external chip such as MAX485.
  • No packet loss: In TCP mode, both wifi and Ethernet serial ports receive and send data at the maximum rate of 115200 BPS without losing 1 byte.
  • Provide serial control instructions: multiple parameters can be configured AT a time, and the configuration instruction efficiency is significantly higher than that of ordinary AT instructions.
  • Supports DNS resolution and can be used as a DHCP Client or a DHCP Server in AP mode.
  • Support in the system through the network port upgrade program. Supports remote network upgrade and automatically restarts after upgrade without manual intervention.
  • Support for configuring web customized downloads. Can be configured for the user's own logo and desired web page. Web pages conform to the HTML generic format.
  • provides advanced functional modules: 7044 is a wifi Modbus gateway module that supports Modbus TCP to RTU and multiple host access; The 7004N is a wifi module that supports P2P functions.
  • Support hardware flow control CTS/RTS and software flow control XON/XOFF.
  • Support TCPServer, TCP Client, UDP, UDP multicast. As a Server, it supports up to 100 TCP connections to communicate with networking modules simultaneously. As a Client, you can connect to eight destination IP addresses.
