[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] 300 VDC available for 42/65 models. Contact EvoLogics for more information on power supply options!
[4] Dimensions of a Delrin housing, other builds are slightly larger. Dimensions vary depending on housing type and installed options.
Contact EvoLogics for more information on device dimensions and weights, request a drawing if necessary.
[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.
