On of the first IP interfaces in the market the doesn't require a separate power supply or Power Over Ethernet (POE) Connection. No compare,use has been made on features with 4 individual tunnel connections and a manual function to enable or disable communications. The bus consumption of the device is 27.3- 34.6 mA depending on the amount of traffic so an allowance needs to be made when specifying the Bus power supply.
