The DCS does not have a function to reset to factory defaults so it is best to check each configuration parameter
listed above for correct values. For a listing of all factory defaults, a file is available for download:

The Ai1 controls power to the sensor so that it is only turned on when required, and off in-between readings. The
readings returned by the DCS which may be displayed in Hydrosphere, Eagle.io or other platforms list in Table 9.

#Do I have decimal mode on or not? It displays zero as 0.0000000E+00. I think I should have it on.

To set up for communication with a PC, connect Green to DB9 pin 2, White to DB9 pin 3 and Black to Ai1 GND. DCS remains powered by Ai1. The terminal must be set up with CR+LF line feeds.

. To set up a DCS, the following settings are recommended. Items highlighted bold are
If the sensor is currently running measurements. This may need to be
repeated
Show all the available settings
Show all the available commands. To see all modes with an
enumerated parameter, view the options under "Argument List for
enumerated properties" at the end of the help message
Passkey level 1 gives permission to write most parameters, although
some may require Passkey level 1000. If a set command results in the
message "ERROR PROTECTED PROPERTY", a higher passkey is required.
Changes between modes such as AiCaP and the serial terminal mode.
Display values in decimal format, i.e. 0.000 instead of 0.000E+00
Set data reports to be numbers only, no text headers
The number of pings for a reading, options 50, 60, 75, 100, ..., 600
The number of pings per second, options 0.1, 0.5, 1.0, 2.0, 5.0, 10.0,
15.0, 20.0, 25.0. Note it must include the decimal. The result of Ping
Number/Ping Rate should be less than 10 so that one reading is
returned each 10s
Does not require polling, transmits based on an interval
The number of seconds between data output reports
Save the settings to non-volatile memory
Run the sensor with the new settings
