Sondes
The YSI sondes are detected in a different manner from the other sensors. EcoWatch instructs
the 6200 DCP to scan and identify any SDI-12 device connected to the SDI-12 bus/port. As each
device is found the 6200 records the sondes’ setup information. This information is then used by
the 6200 DCP to create a configuration file. This file is then used to program the 6200 DCP
sensor, process and output settings automatically.
SYMPTOMS POSSIBLE CAUSE ACTION REF
The sonde SDI12 address is
not 0-9 or A-F Connect the sonde to a terminal
emulator and verify the SDI-12
address. See sonde manual for
instructions on how to set the
SDI-12 address. 3.4 EcoWatch Config

as data. Sonde is disconnected or not
giving data Check the sonde connection,
SDI-12 address and
communication configuration. 3.4
For further sonde diagnostic testing, connect a terminal emulator directly to the 6200DCP,
access the USER menu, select the Test menu and then use the SDI-12 passthrough test
commands.
CAUTION: Once done, don’t forget to enter CONTROL Z to escape.
Power
The 6200 DCP will shut off at a voltage of 10.6VDC. It will then need at least 11.7 VDC to start
up again. This is done to protect the battery from a full discharge. Under normal conditions the
battery should remain fully charged.
SYMPTOMS POSSIBLE CAUSE ACTION REF
Fuse blown Replace fuse 4
Depleted battery Determine what caused the
battery depletion. 4.3
No DC Voltage
Defective Battery Check for 12.5 VDC. Replace
battery if necessary. 4.3
