Combine digital I/O and Serial communication

The digital I/O COM-Server can communicate with analog units through the Internet. The I/O COM-Server is connected directly to the Ethernet. Switch, monitor, count and send serial data With the Web-IO 4.0 Digital you get two units in one. The Web-IO part enables the accustomed variety of protocols and applications for controlling, collecting and monitoring the digital IOs. Also integrated is the function of a serial Com-Server for transmitting serial RS232 data streams. This makes the Web-IO 4.0 Digital 12xin, 12xout, 1xRS232 ideal for use in DNC and MDE applications. Take a break - this is the future - try it now and be convinced.
