FeaturesM4 series 32-bit ARM processor with up to 120MHz frequency, fast speed, stable and reliable10/100M Auto-MDI/MDIX ethernet interface, regardless of cross-over or straight-through cableBoth RS232 and RS485 interface, allows to work independently at the same time, without interfering each otherConfigurable baudrate (600bps~ 230.4K bps), supports
five parity check options: None, Odd, Even, Mark, SpaceMulti indicators, for monitoring communicating and working statusAvailable working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST) Supports Modbus, suit for industrial applicationSupports Websocket, allows bi-directional transparent data transmission with RS232/RS485 port via webpage directlyConfigurable via webpage, AT commands, serial protocol, and network protocol, provides configuration protocol which can be integrated to your own softwareSupports customized heartbeat packets, make sure the connection is truthful, as well as for actively retrieving sensor dataSupports customized registration packets, auto passing the registered packet as identifier after the connection is established, so that different devices can be distinguishedSupports customized webpage, allows user to customize the module configuration pageSupports RFC2217-like protocol, be able to communicate with devices whose serial setting (baudrate, data bit, etc. ) may changeKeepAlive mechanism, detects broken connection, auto re-connectingSupports time-out reboot (no-data reboot), ensures a long-term stable connection, configurable reboot timeSupports DNS domain name resolution, configurable DNS serverSupports DHCP, auto-obtained IP or static IPFirmware is upgradable via the networkRestore to factory settings via software and/or hardwareComes with default MAC address, which
is customizableProvided software: module configuration software, TCP/UDP testing
