DS205 is the 5-port Full-Giga Ethernet switch, the Ethernet ports support 10M/100M/1000M Auto-Negotiation, Energy Efficient Ethernet, QoS traffic prioritizing and 9K jumbo frame forwarding. DS205 is also designed to accept wide power input range from 9.6 to 60VDC and 18-30VAC input. The rugged IP40 design can stand for harsh environment and wide temperature (from -40 to 70°C) use. It is also complying with heavy indsutrial environment EMC level and compact size can fit in for space limited cabinets.
