Switching, monitoring, counting, and transmitting serial data

With the 57731 Web-IO 4.0 Digital, you get two devices in one. The Web-IO part offers the usual variety of protocols and applications for controlling, recording and monitoring the digital IOs. In addition, the function of a serial com server for the transmission of RS232 serial data streams is integrated. This makes the Web-IO 4.0 Digital 12xin, 12xout, 1xRS232 ideal for use in DNC and MDA applications.
