The system also outputs a water temperature measurement with every depth measurement made. Software for the "front end" of the Echologger is available to run on a wide range of devices from Pocket PCs, to the full range of desktop and tablet systems running the Windows operating system. Additionally, the Echologger is directly compatible with most traditional land survey acquisition software. 1 3 2 Table 1: Kit Components Part Number 1 2 3 4 4 Description Survey poles Triangle Mounting Bracket TM Echologger TM Echogram Quantity 3 1 1 1 Seafloor Systems, Inc. | info@seafloorsystems.com | +1(530) 677-1019 Page 1 Setup Connection: EU400 1.

The altitude is determined where the threshold meets the first echo-signal. For accurate altitude data appropriate Threshold, Dead zone and Gain have to be chosen. In order to have a real Altitude at appx. 6.0m (2) è Increase Deadzone to ~500mm in order to avoid the first peak (1) èOr increase Altimeter Threshold (yellow dotted line) so that the threshold can meet the real peak (2) first, not peak (1) The rules of thumb are, - Set the Deadzone big enough to avoid initial reverberation (1) - In Altimeter modes (Simple, NMEA, PSA-916) increase the Gain, so that the Echo signal can be big enough (saturated). This will help to keep the Echo signal amplitude minimizing fluctuation. But also watch other unwanted reflections amplified by this Gain. - The Threshold should be as small as possible. But it should be more than the unwanted signals, otherwise false values will be calculated from these unwanted reflections, not from the bottom of the water. This is when users feel the altitude values from the device are not accurate, but this is a matter of setting optimal parameters using Echogram at Echosounder mode (not at Altimeter mode) *Example of settings Altimeter mode for altitude measurement ECT400, ECS400, EU400 (450kHz): Tx Length: 100 µsec Deadzone: 300 mm Threshold: 10% Gain: +10 dB Offset : +35 mm (when altitude from the front face of the transducer is required) Speed of sound :1,480 m/s (fresh water at 20degC) Seafloor Systems, Inc. | info@seafloorsystems.com | +1(530) 677-1019 Revised 11/18/2021 Page 10 FAQ 10.

Trouble shooting (known issues) Seafloor Systems, Inc. | info@seafloorsystems.com | +1(530) 677-1019 Revised 11/18/2021 Page 16 FAQ (1) Parameters cannot be changed : At RS485 interface, if interval between pings is to small (especially at long range), interruption from a controller (PC) such as changing parameters may not work. RS485 is half duplex so that commands from the controller can be transmitted to the device during the gap between each data transmission. (refer to max range vs interval table) In order to recognize commands coming from the PC, the device should have enough time between pings. First, the device should be stopped. At terminal program, press `space bar' several times VERY FAST so that device stops (means collecting data stops). At the GUI software, press "Apply" several times VERY FAST until device stops receiving data. Once the device stops, now it can receive commands. New parameters with appropriate Range, Interval can be set in both terminal program or in GUI, then start the device with a command `#go' or `Apply'. (2) Cannot connect the device to a controller (PC). Checking at terminal program some strange characters are shown (@RS485) : TX+ / TX- wires connected in opposite Seafloor Systems, Inc. | info@seafloorsystems.com | +1(530) 677-1019 Revised 11/18/2021 Page 17
