1. Introduction

1.1

Some users of the YSI EXO sonde may wish to
incorporate a photosynthetically active radiation
(PAR) sensor into their field monitoring equipment.
This sensor can be added to the YSI EXO2 sonde
in the form of a special adapter engineered by
YSI’s Integrated System & Services division. This
appendix is designed to give potential users of
this PAR adapter information on how the system is
configured and the steps necessary to acquire and
log PAR data with the EXO PAR adapter.

1.2

Li-Cor PAR sensors are required for the EXO PAR adapter and these sensors can either be supplied to YSI by the
customer (brass mounting screws provided with the sensor are required for installing on the par system) or can be
purchased from YSI as part of the complete system. These sensors are then mounted to arms which extend from the
sonde on either side. Output cables are then attached to the sensors which connect to the EXO PAR adapter, which in
turn connects to the EXO2 Auxiliary port on the top of the sonde, as show in Figure 1.

Figure 1 shows the installation of two sensors (one pointing up, the other pointing down), but it is also possible to use a
single PAR sensor in either an upward or downward looking configuration.

Your EXO PAR system is shipped separate from your EXO2 sonde and can be installed onto the EXO2 sonde following
these easy steps.

The EXO PAR Systems consists of 3 main parts: The EXO PAR adapter cylinder and cables, the black plastic frame
system and calibration cup extender, and the Li-Cor PAR sensors.

The EXO PAR system attaches to the EXO2 sonde via an upper and lower clamp system. The EXO PAR adapter
attaches to the AUX port on the top bulkhead of the EXO2 sonde. For shipment and storage, the EXO PAR system can
fold its sensor and support arms in, along the body of the EXO2 sonde (figure 2).

2. Installation

2.1

Once you’ve unpacked the EXO PAR system, attach the EXO calibration cup extender to the bottom of your calibration
cup. It simply clicks on by inserting the bottom of the calibration cup into the top of the extender and pushing down
on a hard surface (figure 3).

The calibration cup extender provides you the extra height you will need to prevent your PAR sensors and cables from
impacting the ground. It’s ideal for in lab use but we recommend using a lab stand as well for stability, to prevent your
sonde and PAR system from tipping over and potentially causing damage.

CAUTION: Potential pinch hazard, be mindful of fingers.

Attach EXO Calibration Cup Extender

Figure 3 Push down to mate the extender onto

the calibration cup.

2.2

Now that your calibration cup extender is installed, stand the sonde in an upright position and slide the EXO PAR
system frame over the EXO2 sonde. The two clamps; upper and lower are fastened to the EXO2 sonde body via two,
5/16-18 x 2.75” socket cap bolts. You will need to use a ¼” Allen wrench to secure these two bolts. Tighten the bolts
until the clamp fits snug to the body of the sonde. Proper alignment of these clamps, as described below, should be
followed as to not damage either system.

NOTE: Install the EXO PAR system with the EXO PAR adapter cylinder on the same side of the sonde where the
AUX port connector is located. You will connect the EXO PAR adapter into this AUX port.

Installation

1. The top of the upper clamp should align with the yellow bulkhead of the sonde (where the blue meets the yellow).

Proper alignment is necessary so that the PAR sensor arms are deployed at the correct angle

NOTICE: Proper alignment of clamps is necessary to prevent damage.

Figure 5 Align the upper clamps with the yellow bulkhead of the sonde

2. The bottom of the lower clamp should align with the upper edge of the top chamfer on the clear plastic section

covered with the black “EXO²” sonde label. Again proper alignment is necessary so the PAR sensor arms are
deployed so that the PAR sensor faces axis is parallel to the sonde axis.

NOTICE: Proper alignment of clamps is necessary to prevent damage.

Figure 6 The lower clamp should align with the upper edge of the top chamfer on the clear plastic section

3. Once you have the EXO PAR system secured to the EXO2 sonde body it is time to deploy the sensor arms. To do
so simply lift the arms and install the pins where the two arms meet, as shown (figure 7).

Figure 7 Lift the arms and install the pins where the two arms meet

CAUTION: Potential pinch hazard, be mindful of fingers.

4. After you have installed the upper and lower clamps, it’s time to address cable management. There are two cables

that connect to your PAR sensors coming from the EXO PAR adapter cylindar. Supplied with your EXO PAR system will
be several black, UV resistant Zip Ties. Fasten the sensor cables to the EXO PAR frame support arms as follows:
(3 locations)

NOTE: Dummy plugs are supplied for these cable’s connectors, plug these connectors when sensors are
removed or if only deploying 1 of your 2 PAR sensors. When not in use, the plugs can be stored in the
calibration cup extension.

Installation

3. Setup

Now that your EXO PAR system is installed, it’s time to connect your EXO PAR Sonde to either your PC running KOR or
your EXO handheld system. For PC applications, you can use the Bluetooth functionality of the EXO to connect with
KOR. For EXO handheld applications, you will need to connect an EXO field cable between the EXO communications
bulkhead connector and the EXO handheld communications bulkhead connector. The EXO field cable comes in
differing lengths depending on your needs, its part number is; 599040-xx (the –xx signifies the cable length; ex -2
equals 2 meters) Cable lengths start at 2 meters.

If the EXO PAR sonde is connecting to a data logger, you can use the EXO flying lead cable, part number 599008-xx
(again the –xx signifies the cable length) flying lead cables start at 10 meters. You will also need the EXO DCP adapter
to connect to a data logger, part number 599820.

Each Li-Cor PAR sensor is supplied with a Certificate of Calibration, shown below (figure 9). The calibration certificate
contains the multipliers for the sensor. YSI uses the in-water multiplier for our EXO adapter, providing PAR engineering
units out as data. In the following sections, we will review where and how to end this multiplier into either KOR EXO
software or the EXO handheld display.
