[1] Accuracy obtained in environment with a fl at sound velocity profi le, slant ranges estimated in local coodinate frame of the device  without the aid 
     of AHRS/GNSS and/or any other sensors contributing to the resulting accuracy. Slant range estimation is based  on the measured propagation time,               slant range accuracy depends on sound velocity profi le, 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] 300 VDC available for 42/65 models. Contact EvoLogics for more information on power supply options! 
[5] 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. 
[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-channel 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.
