1) Slant range estimation is based on the measured propagation time, slant range accuracy depends on sound velocity profile, refraction and signal-to-noise ratio.
2) One RS-232 Interface can be replaced with a RS-422 interface. Contact EvoLogics for more information!
3) 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.
4) Contact EvoLogics for more information on external and internal power supply options.
5) Dimensions of a Delrin housing, other builds are slightly larger.
6) Internal Xsens® MTi AHRS (Attitude and Heading Reference System) compensates the changes of roll, pitch and heading. Power consumption increases by 400 mW with AHRS installed.
7) 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.
8) The Power Switch is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422.
