Bộ chuyển đổi 1 cổng RS-232 + 1 cổng RS-485 sang Ethernet ICP DAS PDS-720D
Introduction
PDS-700 series are Programmable Serial to Ethernet Device Servers designed to meet the common requirements of Internet/Ethernet applications. They are easy to use to remotely control your serial devices through Ethernet networks. The PDS-700 comes with a powerful and reliable Xserver programming structure for you to design your robust Ethernet applications in one day.
PDS-700 series are designed for linking RS-232/485/422 devices to Ethernet networks. With the VxComm utility, the built-in COM port of PDS-700 can be virtualized to a standard COM port of a host PC. By virtue of its independent operating system, protocol independence, small size and flexibility, device servers are able to meet the demands of virtually any network-enable application. Most devices don’t have network ports. Our Programmable Device Servers allow those devices to become connected to the network.
