5 Port 10/100 Mbs Ethernet Switch Power inputs: +5V to +30V DC Compact design with integral wall mount No software required - Simply plug in and connect Integral wall mount or optional DIN rail mount Connection speed and activity LEDs on each Port Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port only. This allows simultaneous communication across the switch, improving bandwidth.
