ZLAN7146 RS232/485/422 To WIFI Converter Module Support Modbus TCP to RTU

7146 adopts the latest WIFI chipset, which has stronger WIFI performance and higher cost performance. Use ARM M4 kernel, main frequency 192MHz, and use real-time operating system. The ZLAN7146-5 supports connecting WIFI hotspots of 5.8G (currently both of them are 2.4G frequency bands in AP mode), and others are similar to 7146.

7146 supports one RS232/485/422 to WIFI, can be as a STA or AP mode. There is no Ethernet interface (RJ45 is for future extended use). Support Modbus TCP to RTU, support sending heartbeat packets, registering packages and transcoding scripts.

The typical application is shown as FIG. 2. The original serial devices connect with ZLAN7146, then connect ZLAN7146 to wireless network through the WIFI. Then any data sent by serial device will be transparently transferred to the PC designated by ZLAN7146, and data sent to ZLAN7146 from PC via network will also be transparently transmitted to the serial device.

Features

1. Support 802.11b/g/n.

2. Wide voltage power supply: 9~48V supply scope. The power input type can choose industrial terminal or normal power adapter plug.

3. Support three forms of serial port: RS232/485/422. Support hardware flow control CTS/RTS and software flow control XON/XOFF.

4. Sticky package optimization, the real-time of serial framing is strong. The serial packet sub-package interval of ordinary WIFI serial port server is over 100ms, ZLAN7146 is optional 1ms~100ms, resolution precision is greatly improved.

5.Support upgrading program through Ethernet port in the system. Support remote network upgrades.

6.Support wifi connection between modules.

7.Provide 4 kinds LINK indicator interface: Link blue indicates the TCP connection established, LINK green indicates the Ethernet cable is connected, WIFI blue indicates establishing wifi connection as AP or STA, WIFI green indicates the wifi function works normal. The abundant indicators can directly shows the device status.

8.One-key search configuration. When the wifi and PC or router establish link, using ZLVircom software to one-key search and configure device parameters, the IP of device and PC no need in a segment.

9.Support DNS, support as a DHCP client, as a AP mode can also be as a DHCP Server.

10.Support TCP sever, TCP client, UDP/UDP multicast. As Server can support up to 30 TCP connections communicating with the networking module at the same time; as Client can connect to 7 destination IP.

11.Support the function of device connecting with sending MAC address to facilitate cloud management of devices.

12.It supports remote viewing of TCP connection status, serial port data sending and receiving status of devices through software. Virtual serial port supports data monitoring.
