The switch provides eight 10/100Mbps copper ports for connections to Ethernet and Fast Ethernet devices. With the featured auto-negotiation function, the switch can detect and configure the connection speed and duplex automatically. The switch also provides auto MDI/MDI-X function, which can detect the connected cable and switch the transmission wire pair and receiving pair automatically. This auto-crossover function can simplify the type of network cables used.

For industrial environment, the device is designed with the following enhanced features exceeding that of commercial Ethernet switches:
– High and wide operating Temperature
– Power input interface: Industrial screw terminal block and DC power jack for external commercial power
adapter as option
– Screw panel and DIN rail mounting support for industrial enclosure
– Industrial-rated Emission and Immunity performance

Key Features:

  • Auto MDI/MDI-X crossover function on the TP copper port
  • Support IEEE 802.3x flow control for full-duplex operation
  • Support Back-pressure flow control for half-duplex operation
  • Wide operating temperature range for temperature critical environment
  • Support DIN-rail mounting and panel mounting
  • Provide two power input types to meet more application needs
  • Power saving mode for port link down
  • Accept wide power input voltage range for application flexibility
  • Industrial-rated Emission and Immunity performance
