1) One RS-232 Interface can be replaced with a RS-422 interface. Contact EvoLogics for more information!
2) Power consumption for RS-232 interface. Add 500 mW if an Ethernet interface is installed. Add 300 mW if the Wake-Up Module is installed. User-configurable Listen Mode is only available with a Wake-Up module installed. Power consumption in Listen Mode depends on Listen Mode settings.
3) Contact EvoLogics for more information on external and internal power supply options.
4) Dimensions of a Delrin housing, other builds are slightly larger.
5) The Wake Up Module is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422. 2-interface Wake Up Module version reacts to incoming data on two serial interfaces.

6) The Power Switch is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422.
