LS Electric NTS Network Terminal Servers (NTS-50 / NTS-300)

LS Electric NTS Network Terminal Servers (NTS-50 / NTS-300)

LS Electric Beyond X NTS network terminal servers that convert between serial (RS-232C / RS-422/485) frames and Ethernet packets, in a 4-port DIN-rail NTS-50 and 8/16-port 19-inch 1U NTS-300 with optional redundant power.

Key features

  • Serial-to-Ethernet media conversion with up to 4 simultaneous TCP channels per serial port
  • Web-browser configuration and monitoring (WEB-Console), no dedicated software needed
  • INS-VCom virtual COM port software for legacy PC applications
  • Diagnostics: frame monitor, port status, port analyzer, serial loopback, IP scan, TCP connect
  • TCP/IP and UDP/IP, watchdog, fanless design
  • NTS-300 R models add dual AC inputs for power redundancy
