Product description: RS232/RS485 converter - Ethernet - Cortex M4
A device allowing communication between RS232 or RS485 and Ethernet RJ45 interfaces. Module configurable via web page, AT commands, serial protocol and network protocol. It is based on an ARM Cortex M432-bit processor.It supports the following modes of operation: TCP server, TCP client, UDP server, UDP client, HTTPD client. Supports Modbus for industrial applications.
RS232/RS485 - Ethernet converter.
Main features of the converter
- ARM Cortex M0 32-bit processor.
- Ethernet 10 / 100 Mb/s Auto-MDI/MDIX interface.
- RS232 and RS485 interfacescan operate independentlyat the same time.
- The possibility of changing the transmission speed of the RS485 interface (from600 b/s to 230.4 Kb/s),supports five parity checking options: None, Odd, Even, Mark, Space.
- Status diodesfor monitoring communication and operation status.
- Available modes of operation: TCPserver, TCP client, UDP server, UDP client, HTTPD client (supports GET and POST).
- Supports Modbusfor industrial applications.
- Supports Websocket, provides bidirectional, transparent transmission from the RS232 / RS485 port directly through the website.
- Enablesconfiguration of heartbeat packets, make surethe connection is correct to receive data from the sensor.
- Enables configuration ofregistration packets, automatictransmission of the registered packet as an identifier when the connection is established, so you can distinguish between devices.
- Configuration: via website, AT commands, serial protocol and network protocol.
- The module configuration page can be freely edited.
- It supportsa protocol similar to RFC2217 and cancommunicate with devices whose serial settings (baud rate, data bit, etc.) may change.
- The KeepAlive mechanismdetectsconnection breaks and automatically restores them.
- It supportstime-out reboot.
- Recognizes DNS domain name, configurable DNS server
- Supports DHCP,auto IP address assignment or fixed IP
- The firmware is updated over the network
- Resetting the device to factory settings is done by software or hardware
- It has a MAC address that can be edited
- Available software: module configuration software, TCP/UDP test tool, VCOM virtual serial port
- Example code: host computer (socket), VB, C++ Delphi, Android, iOS, etc.
Included is also 5 V / 1 A power supply for supplying the converter and RS232 male - female, female - female and RJ45 cable.
