The serial wireless module ZLSN7046T is a wifi to serial module launched by Shanghai ZLAN . It can convert wifi signals into serial signals and supports multiple functions. It is packaged in a stamp hole and is small in size. It can be equipped with an external antenna or a built-in antenna. 7046T supports a UART TTL level serial port to WIFI and can be used as a STA or AP mode. It supports a high baud rate of 921.6Kbps . 7046T is not a simple serial port to wifi module. It has many advanced functions such as Modbus TCP , custom registration report, custom protocol conversion, etc. It is very suitable for IoT applications. It only has a wifi interface, low power consumption, 3.8mA standby power consumption , and 95mA at full speed . The advanced functions of 7046T include: support Modbus to RTU , support multiple hosts to access simultaneously without conflict, support custom heartbeat package and registration package function, support "transcoding" custom protocol reading and conversion function, support http data submission and distribution function, and support TCP server and client coexistence. Supports cross-segment device search using zlvircom tool, supports remote upgrade and web page customized download. Supports binary format AT- like commands, no need to switch to AT configuration mode. ZLSN7046TN supports P2P communication.

In terms of hardware, 7046T uses the latest WIFI chipset, ARM M4 core, 192MHz main frequency, and real-time operating system. Among them, ZLSN7046T-5 supports connecting to 5.8G WIFI hotspots . The wifi mode supports 802.11b / g / n , and supports WEP64 / 128 , TKIP, AES, WPA, WPA2, and WAPI encryption modes. When 7046T and the computer are connected to the same AP , the computer and the module can communicate with each other. 7046T has a strong receiving sensitivity, and the indoor communication distance can reach 70 to 100 meters with the built-in antenna . 7046T meets ROSH requirements.

The 7046T has a power supply voltage of 3.3V and has a rich set of external function pins, including 485 send control pin, run indicator light, data activity indicator light, TCP connection indicator light, wifi working module indicator light, wifi connection indicator light, etc.

Features

50. Supports 802.11b/g/n .
50. Supports hardware flow control CTS/RTS and software flow control XON/XOFF .
50. Supports upgrading the program through the network port in the system.
50. Support WiFi connection between modules .
50. One-click search and configuration. When the WiFi and PC or router establish a link, the ZLVircom software can be used to search and configure device parameters in one click. The device IP and PC do not have to be in the same network segment.
50. Supports DNS resolution, supports being a DHCP Client , and can also be a DHCP Server when in AP mode .
50. Supports TCP Server , TCP Client , UDP , UDP multicast. When used as a server , it supports up to 30 TCP connections to communicate with the networking module at the same time; when used as a client , it can connect to 7 destination IPs .
50. Supports sending MAC address function when device is connected , which is convenient for cloud management of devices.
50. Support remotely viewing the device's TCP connection status, serial port data sending and receiving status through software . Virtual serial port supports data monitoring function.
50. Support Modbus gateway function, support Modbus RTU to Modbus TCP . Support storage-type Modbus , can automatically collect device data and store it; also support non-storage mode Modbus gateway.
50. Support multi-host function: In a question-and-answer query mode, the network port allows multiple computers to access the same serial port device at the same time.
50. Supports custom heartbeat package and registration package functions: It can facilitate communication with the cloud and device identification.
50. Supports the function of requiring password authentication when establishing TCP connection to ensure connection security.
50. Supporting the "transcoding" function, it can translate the protocols of specific devices and allow different devices to connect to a unified software platform.
50. Supports data submission and distribution via http . The cloud can directly use http GET instructions to interact with the serial port data of the device.
