until 10:10, when the next readings would be sent to the 6500. The “Sample and Hold” feature is
explained in more detail in Appendix G. Using Your Drinking Water Sonde with a YSI 6500
Process Monitor.
• Attached to a Data Collection Platform (DCP) – In the absence of a SCADA system, the sondes
can be attached to DCPs such as the YSI EcoNet system and the YSI 6200 to allow access to the
data via modem communication. For the 6200, the YSI software package EcoWatch DCP is used
and data can be transferred directly to your computer via a land-line or cellular modem or, for
short distances, via spread spectrum radio. For the EcoNet system, data is transferred via modem
to third party server where it can be accessed by the user via a simple Internet link.
What type of cable will I need for setting up and deploying the drinking water sondes?
Depending on your applications, two types of YSI cables can be used with your DW sondes:
• 6067B -- If your applications involve the stand-alone scenario described above where the instrument is
powered on internal batteries and then recovered for data upload, then the relatively-inexpensive
6067B is probably the ideal interface cable to your DW sonde. The cable can be used in the
laboratory to set up the instrument for deployments to upload data in the laboratory or in the field to a
PC when no provision for a water tight connection is required. Note, however, that you cannot
interface between the 650 Display/Logger and a sonde with this cable, so if you will be using the 650
for periodic uploads, you will require a YSI field cable as described below.
• Standard YSI Field Cables – If your applications involve the further interface of the DW sonde to a
device other than a PC, you will need a YSI field cable in the appropriate length for your conditions.
These cables have a YSI Model Number “609X” where the value of “X” determines their length.
These cables have a connector on one end which attaches to the sonde and a military-style (MS-8)
connector on the other end which will directly interface to a 650 Display/Logger, a 6500 Process
Monitor, and 6200 and EcoNet data collection platforms. If you wish to use your field cable for
laboratory calibration while interfacing the sonde to a PC, you will require a YSI 6095B adapter which
has a mating MS-8 connector at one end and standard serial connector (DB-9) at the other.
What will I need to supply power to my drinking water sondes?
For stand-alone deployments and real-time applications using EcoWatch for Windows, the sondes can be
powered using internal batteries where the 6920DW and 600DW-B will have a battery life of about 30 days
at a 15 minute sample interval. If AC power is present at the site of the stand-alone deployment, then it is
probably prudent to use the YSI 6038 (US and Canada) or the YSI 6651 (all countries) power supplies to
provide power. To use these power supplies, you must have a field cable with a 6095B adapter attached to
the sonde; the power input from the supplies goes through an MS-4 connector on the 6095B. The power
supply will also connect to a 6067B calibration cable.
For applications involving the YSI 6500 or any data collection platforms, the sonde will automatically be
powered from the 6500 (attached to AC power) or DCP (attached to either AC or DC power). However, if
you are logging back-up data to the sonde memory while also collecting it via the DCP or a SCADA
system, you probably will want to have batteries in the sonde so that data will continue to be collected and
stored in internal memory if the power to the 6500 or DCP is interrupted.
