Features: 1.32bit ARM Processor: M4 series 32bit ARM processor, frequency up to 120MHz, fast speed, stable and reliable. Multi index , suitable for industrial applications.Supports Websocket for bidirectional transparent data transmission with RS232/RS485 port directly through web pages 2.MDI/MDIX Ethernet Interface: 10/100m Auto MDI/MDIX Ethernet interface, whether crossing cable or straight through cable.Support custom mode. Supports timeout restart (restart without data) to ensure long term stable connection. The restart time can be configured. Software: module configuration software, TCP/UDP test tool, VCOM virtual serial port software 3.RS232 and RS485 Interface: Can work independently at the same time, mutual interference. Configurable via web pages, AT instructions, serial protocol, providing configuration protocols that can be integrated into your own software. Supports DHCP, automatic IP address obtaining, and static IP address obtaining 4.: The baud rate ranges from 600bps to 230.4Kbps. Five parity check options are supported: None, Odd, Even, for Mark, and Space. The KeepAlive mechanism detects and automatically reconnects disconnected connections. Firmware can be upgraded over the network. Restore factory Settings by software and/or hardware 5.Multiple Indicators: Multiple indicators for monitoring communication and working status. Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (support GET and POST). Supports DNS domain name resolution and can be configured with a DNS server. specification:Item Type: RS232/RS485 to Ethernet Converter Material: Metal Shell Ethernet: Connector: 4pin RJ45 Communication Rate: 10 / 100Mbps Interface Protection: 2KV Electromagnetic Isolation Protocol: IP,TCP,UDP,ARP,ICMP,DHCP,DNS,HTTPD Client, Websocket TX Cache: 16Kbyte RX Cache: 16Kbyte RS485/RS232 Connector: RS485: Screw Terminal (A +, B -, GND) RS232: DB9 Male Data Bits: 5bit, 6bit, 7bit, 8bit Stop Bit: 1, 2 Parity Bit: None, Odd, Even, for Mark, Space Baud Rate: 600bps-230.4Kbps TX Cache: 2Kbyte RX Cache: 2Kbyte Hardware Flowing Control: RTS/CTS Interface Protection: RS485: 2KV ESD Protection, Anti Thunder, Surge Protection and Overcurrent Protection RS485 Pull Up / Pull Down Register: 2.2K Power: Power Supply: 5.0 - 36.0V (5V Recommended) Working Current: 86.5mA (5V) Power Consumption: < 1W Interface Protection: Anti Reverse Connection, Esd Protection, Anti Surge Environmental Science: Operating Temperature: - 40 - 85 Storage Temperature: - 40 - 105 PackageList: 1 x RS232/485 to ETN 1 x Power Adapter 1 x Netting 1 x Male to Female Serial Port Line 1 x Female to Female Serial Port Cable
