Product description: Converter RS485 - Ethernet - Cortex M0
Device that allows communication between RS485 and Ethernet RJ45 interface. The module is configurable via web page, AT commands, serial protocol and network protocol. It is based on ARM Cortex M0 32-bit processor. Supports TCP server, TCP client, UDP server, UDP client, HTTPD client operating modes.
Main features of the converter
- ARM Cortex M0 32-bit processor.
- Ethernet 10/100 Mbps Auto-MDI/MDIX interface - supports both straight and cross-over cables.
- Possibility to change transmission speed of RS485 interface(from 600 b/s to 230.4 Kb/s), supports five parity checking options: None, Odd, Even, Mark, Space.
- Modes of operation: TCP server, TCP client, UDP server, UDP client, HTTPD client (supports GET and POST).
- Configuration: via web page, AT commands, serial protocol and network protocol.
- Allows configuration of heartbeat packets, make sure the connection is correct to correctly receive data from the sensor.
- Allows configuration of registration packets, automatically forward the registered packet as an identifier when a connection is established, so that devices can be distinguished.
- The configuration page of the module can be freely edited.
- Supports a protocol similar to RFC2217, can communicate with devices whose serial settings (baud rate, data bit, etc.) may change.
- KeepAlive mechanism, detects connection breaks and automatically restores them.
- Supports time-out reboot.
- DNS domain name recognition, configurable DNS server.
- Supports DHCP, auto IP address assignment, or fixed IP
- Firmware is updated via the network
- Reset of the device to factory default settings is performed by software or hardware
- It has editable MAC address
- Available software: software for configuring the module, TCP/UDP test tool, VCOM virtual serial port
- Example code: host computer (socket), VB, C++ Delphi, Android, iOS, etc.
