External serial servers that provide connectivity to any serial device
Digi serial servers and serial cards connect critical equipment to applications and enable port expansion in small workspaces and specialized server/PC environments. Available serial server models offer 1, 2, 4, 8, 16, and 32 port serial-over-Ethernet options with transparent connectivity for existing serial applications via Digi's RealPort driver, or via TCP or UDP sockets. TLS, SSL or SSH based connections provide robust encryption. 232-only and MEI (selectable) 232/422/485 servers are available.
