The Serial-TCP program bridges your existing Serial COM port and TCP/IP without the need for changing existing protocol. It works seemlessly and transparently, just like a pair of passive RS-232/RS-485/RS-422 repeaters. The applications of the Serial-TCP program include extending serial (RS-232, RS-485, RS-422, and TTL, etc.) communication distance via TCP/IP; expanding the capability of your existing TCP/IP control software; and analyzing TCP/IP and COM network with the built-in ‘Ping’, ‘Resolve IP Address/Host Name’, ‘COM Port State LEDs’, and ‘Data Logging’ tools and features. The Serial-TCP program is also very helpful when you are developing your own TCP/COM control software. The Serial-TCP supports all major Windows OS, including Windows 8, 7, Vista, and XP, both 32 and 64 bits.
