Supply the protocol for VIP customers
Provide PC TCP/IP SOCKET programming example, VB, C++, Delphi, Android, IOS.
A built-in web page, also parameter setting via web, can customize web pages for users.
Can also set via UDP broadcast, provide the set up protocol.
Reload button, a key restore default Settings.
RJ45 status indicator light, RJ45 interface built-in isolation transformer, 2 KV isolation.
The global unique MAC address bought from IEEE, the user can define MAC address (please state when you make order).
Support upgrade firmware via network.
Support remote IP and domain name at the same time
Support up to 8 link from client when act as TCP Server, same data will be send to all client.
Can modify http server port from default port 80 for module built-in http server.
Support Keepalive, detect a dead link quickly and make sure the connection more stable.
