Summary

ZLAN7004 is a high-performance wifi/Ethernet to serial port module developed by Shanghai ZLAN. Different with the normal wifi module positing in low cost, 7004 posit in high-performance, abundant functions, the design goal is oriented to industrial field with high requirements for function and stability.
7004 is developed on the basis of over 10 years product design experience and software technology accumulation in TCP/IP to serial port field by Shanghai ZLAN. The software system is same as ZLSN2002 Ethernet to serial port product, and has same stability and rich function as ZLSN2002. 7004 use 11pin + 12pin dual-pin structure, the appearance is compatible with ZLSN2002 with power supply 3.3V. The serial port connect user device TTL level port through RXD, TXD, GND of 3 pin UART, the other end connect through WiFi or Ethernet. The WiFi supports STA mode connecting wireless router, or as AP mode to make WiFi devices as phone connect. The module has network transformer, user can use RJ45 with network transformer directly connect with the module Ethernet port.
ZLSN7004 can be applied to security monitoring, intelligrid, factory automation, energy environment detection, intelligent transportation, intelligent household and other field, it can make your system immediately upgraded to WiFi.

Features

  • 1) Support Ethernet and WIFI simultaneous access.
  • 2) The internal integrate real-time operating system, fast start.
  • 3) The serial port has real-time response speed. The packet frame interval is adjustable 1~255ms. The kindred WiFi module can only reach minimum 20ms or 100ms frame ability, but 7004 can reach 1ms real-time frame performance.
  • 4) One-key search configuration. When forget SSID or password the WiFi cannot find module, just plug in cable, use ZLAN ZLVircom tool can immediately find module and can configure parameters of WiFi, network even they are not in a same segment. Also provide Web configuration method.
  • 5) Provide reset button. Can reset WiFi parameter and IP address of module.
  • 6) Provide 4 kinds LINK indicator interface.
  • 7) WiFi support connection in pairs between modules.
  • 8) Support 485_TEN pin, convenient to connect with MAX485 and such RS485 external chip.
  • 9) No packet loss: in TCP mode, either WiFi or Ethernet port receiving or sending data in maximum rate 115200bps will not loss 1 bit.
  • 10) Provide serial port control command, can configure multiple parameters one time.
  • 11) Support DNS, support as a DHCP client, as an AP mode can also be as a DHCP Server.
  • 12) Support upgrading program through Ethernet port in system. Support remote network upgrades, automatic restart after upgrade without manual intervention.
  • 13) Support configuring WEB custom download. Can be configured to the user’s own web pages.
  • 14) Provide advanced function modules: 7044 support Modbus TCP converting to RTU and multiple host access to wifi Modbus gateway module. 7004N is a wifi module supporting p2p.
  • 15) Support hardware flow control CTS/RTS and software flow control XON/XOFF.
  • 16) Support TCP sever, TCP client, UDP/UDP multicast. Support up to 100 TCP connections communicating with network module when as Server; can connect to 8 destination IP when as Client.
