  • Active/passive mode can be independently set for send and receive loop
  • Half-duplex mode with automatic echo suppression
  • Galvanic isolation in all modes
  • Serial transmission speed up to 19.2 kbps
• 1x Ethernet 10/100BaseT
  • Autosensing/Auto-MDIX
• alternate hardware configuration
  • for RS232/422/485 version, see Com-Server ++

Management and connectivity:

• Remote configuration
  • Startup using WuTility (three clicks and you’re done), DHCP, serial
  • Web-Based-Management
  • Telnet
  • Control sockets from your own applications
• Transparent communication
