Aport-211S
Serial-to-Ethernet Gateway with eight digital I/Os
The Aport-211S is an easy-to-use Serial-to-Ethernet gateway which is designed for applications requiring quick, reliable and seamless integration of existing RS-232/422/485 devices to an Ethernet network.
The Aport-211S provides a transparent data channel between serial device and the TCP/IP network, so that the serial device can be accessed by using standard TCP/IP protocols.
The Aport-211S can behave as a TCP server or a TCP client node on an Ethernet network to fulfill versatile application requirements.
Besides, the Aport-211S also provides 6 TTL plus 2 CMOS digital I/Os. A pre-defined ASCII command set is provided for users to control these I/Os through LAN/WAN.
