Four Port Device Server
- 4 Port Device Server is a protocol converter which transmits the Serial Data sent by equipment, as TCP packets to the IP Network and converts the TCP / IP data received from the IP Network back to Serial data before sending it to the equipment. EAD also supports UDP Protocol for Broadcast applications.
- EAD-04 is a low cost, Four Serial RS 232 to Ethernet LAN 10/100 Mbps connectivity system using the TCP/IP protocol and is based on ARM Cortex M4 High speed 32 – bit Microprocessor. EAD–04 has built-in web server for configuration through Web browser and a factory default load switch to load the default configuration setting.
- This also support one RS 485/422 Serial Port for connecting over LAN.
