Features: - 1, 2 or 4 RS-232 RJ-45 serial ports - 9-30VDC power supply PortServer TS serial servers offer a simple, reliable and cost-effective solution for connecting multiple serial devices over industry standard Ethernet. They are available with one, two or four RS-232 serial ports. Target applications for PortServer TS include retail/point-of-sale, building control and medical point-of-care. PortServer TS is ideal for applications requiring COM ports or where TCP/UDP Sockets, or UDP multicast functionality is required.
