The Paytech/DIGI INTERNATIONAL PortServer TS is a serial-to-Ethernet terminal server that bridges legacy serial devices into IP networks. It supports switch-selectable RS-232/422/485 interfaces and delivers up to 230 Kbps throughput with full RealPort technology for transparent COM/TTY port redirection. The device integrates industrial-grade ESD protection, dual-layer encryption via SSHv2 and SSL/TLS, and comprehensive network management through web, CLI, and SNMP interfaces.
