4. Deployment
a. Activate the Diver-Link
b. Deploy ina well
Steps1and 2 must not bedone in thefield to avoidthe seal becoming dirtyand water and dust
entering the Diver-Link.
All thesteps in this chapter are summarized in thedocument Diver-LinkPreparation andInstallation.
2.2 PreparingtheDiver-Link
2.2.1 Openingthe Diver-Link
Open the Diver-Link by inserting ascrewdriver (size 3) inthe slot at thetop of the Diver-Link as shown
in thefigure below. Carefully push the screwdriver down; towards the Diver-Link as indicated by the
arrow until the Diver-Link clicks open.
2.2.2 InsertingaSIMCard
Oncethe Diver-Linkis open,the lidcan belifted. The Diver-Link requiresamicro SIMcard for
communication over the cellular network. If youare managing your dataplan through Van Essen
Instruments, a SIMcard is installedin theDiver-Link prior to shipment. Continue withthe following
stepInserting the Battery.
If youare managing adata plan throughathirdparty (local SIMcard), youmust obtaina microSIM
card from theirservice provider and install it yourself. Obtain the APN settings of the SIMcard and
ensurethattheSIM cardisunlocked (noPIN).
OnceaSIM card is obtained,installit in the Diver-Linkasshown below. TheSIMcard slot is located
near thehinge on thetop sideof the Diver-Link.

2.2.3 InsertingtheBattery
TheDiver-Link is powered by one or twolithium D-cellbatteries (typeER34615).
IMPORTANT
•Insert the battery withthe positive and negative pole in thecorrect direction. The negative
pole must beconnected to the spring connector of thebattery holder.
•In casetwo batteries areused: both batteries must facethe same direction.
•Theorientation of the battery holdermayvary: batteries lengthwise(left image)orcrosswise
(right image).
2.2.4 InsertingtheDesiccant
After thebattery andthe SIMcard are installed, thesupplied desiccant mustbe removed from its
plastic bag andplaced inside the Diver-Link. Place the desiccant next to the battery holder. Once the
desiccant is installed close theDiver-Link as soon as possible.
2.2.5 ClosingtheDiver-Link
Close the lid and press thehinge at thetop towards the bottom ofthe Diver-Link until it snapsback in
position. When closing thelid make sure nocables arepinched by thelid.
2.3 ConfiguringtheDiver-Link
Beforeconfiguring the Diver-Linkaproject mustbesetup inDiver-HUB. The projectstructure,
including monitoring point information, will be used to configure allDiver-
project. For more details see the Diver-HUBGettingStartedGuide.

2.4 ProgrammingtheDiver
Before programming the Diver, aproject must besetup in Diver-HUB. Theproject structure, including
monitoring point information, willbe used forautomatic configurationofthe hardware foreach
monitoring point.
When all monitoring points for theproject are set upin Diver-HUB, import thisproject data into Diver-
Office.
Program the Diveras described in the Diver-HUBGettingStartedGuide.
2.5 ProgrammingtheBarometricDatalogger
There isnoneed toprogram or start the integrated barometric datalogger. The barometric datalogger
copies the sampleinterval and method ofthe connected Diver andoutputs data that covers thesame
time spanas fromtheconnected Diver.See Appendix I TechnicalSpecifications section Integrated
BarometricDatalogger formoredetails.
2.6 Deployment
Connect the Diver to theDiver-Link using a DXT Cable. Optionally, use the DXT Cable Suspension kit
(see Appendix 5.8) to adjust andsecurethe DXTCable tothe topofcasing. The systemis nowready to
be installed ina well. The system can be tested prior to deployment by activating the Diver-Link as
outlined inthe nextsection.

FortheDiver-Link Triple(DN4xx-3)connect up to 3 Divers usingthe connection cables. Thereisno
required order forconnecting the Divers. Incase ofwells withdifferent depths itis suggested to
connect the Divers in orderof well depth: shallowest tothe shortest cable (port 1).
IMPORTANT
•Diver-LinkTriple (DN4xx-3): connectonly Diversbelonging to thesame Diver-HUB project.
Connecting Divers from different Diver-HUB projects to the same Diver-Link Triple results in
data delivery errors.
•The connection cables of the Diver-Link are equipped with caps. Thecap must be used if
thereisnoDiverconnected.
2.6.1 ActivatingtheDiver-Link
Activate the Diver-Link byholding the magnetic key atthe ACTIVATE position for morethan 1 second
as shown inthe picture below. At the frontpanel, the LED indicator with the Diver symbol will
illuminate orange. When it turns green, the magnetic key can be removed,and the Diver-Link starts
theactivation process.
During the activation process theDiver-Link downloads the data from theconnected Diver(s), checks
if aSIMcard is presentand functioning, checks ifa cellular network can be connected to and finally
transfersthe Diver andbarometricdatalogger datatothe Diver-HUB. Each of those steps have a
corresponding LED indicator. For each indicator, the main statusesarelisted in thetable below. Seein
AppendixII LED Indicators &Function Keys for a complete overview of thestatusindicators.
Once the activationprocess is completed, the LEDindicators stay on fora few seconds and willthen
beturnedoffto conservepower.
For the Diver-Link Triple (DN4xx-3), the Diver check will be repeatedthree times inorder of the port
number(short cable =1;middle cable = 2;long cable = 3).TheDiver LED indicatorblinksgreenduring
communication with the Diver connectedto port 1. TheDiver LED indicator turnsredfor
approximately 2 seconds in case ofa connection issue with the Diver, for example no Diver is
connected.

IftheDiver-Link is receivingpoor signal or frequently missestransmissions, check thefollowing to
helpdeterminethe cause:
•The well casingmay prevent the Diver-Link from sending or receiving data. Consider using an
external antenna (AN401, AN402.5 or AN405) thatcan be mounted on the topof the well to
preventcasing interference.
•Check thecellular provider'scoverage areamap. Thedeployment area maybein a non-
coveragearea.
•Check theareasurrounding the Diver-Link system. Objects liketrees, electrical wires, and
walls canaffect cell reception. Consider movingthe Diver-Link toa different areatotest

3.6.3 BarometricDataLoggerNaming
Themonitoring point nameof the barometric dataloggerin theDiver-Linkcannot be programmed (by
the user)and is automatically created by theDiver-Link.
The monitoring point name of a Diver must be unique and mustnot exceed 20 characters. This also
appliestothemonitoringpointnameof the barometric dataloggerin the Diver-Link.
The monitoring point name of the barometric datalogger is derived from the monitoring point name
- , when themonitoring point programmed in theDiver is 18
characters or less.
monitoring point name -
-
resultina monitoring pointnameof more than20characters. Tocreateaunique monitoringpoint
name forthe baro loggerthe following logic isused: The first 13 charactersofthe monitoring point
nameand the serialnumber of the attached Diver areadded - Forexample,if the monitoring
very-long-mon-p-name )anditsserial number is BC567,
then thebarometric datalogger name very-long-monBC567-
3.6.4 BarometricDataLogging
The barometric datalogger starts recording barometric pressure and temperature with a sample
interval of 15minutes after the batteries are inserted inthe Diver-Link and the Diver-Link makes its
first connection withthe cellular network. The firstsample isrecordedat thefirstfull quarterofthe
hour, i.e. H:00,H:15,H:30 orH:45.
The barometric datalogger clock is synchronized with the timeof the cellular network each time the
Diver-Link connects with the cellular network.
TheDiver-Link outputsbarometric datawiththesamesample intervalastheconnected Diver. Since,
the barometricdatalogger records sampleswithan interval of 15minutes,thebarometric datais
resampled with the measurement frequency of the Diver. This principle is illustrated in the images
below.If asampleoftheDiver fallsbetweentwodata pointsofthebarometric data,then nearest
barometric pressure value is usedat thetime ofthe Diver sample. The sameprinciple applies for the
temperature data.

IftheDiverstarted loggingafter the batterieswereinsertedintheDiver-Link(andtheintegrated
barometricdatalogger started logging), thenbarometric data willbeavailable for the entiretimespan
of theDiver. However, ifthe Diverstartedlogging prior to theintegrated barometric datalogger, then
nobarometric data willbeavailable, asdepicted by thegreyarea in thefigurebelow. The barometric
dataloggerwill still outputdata points at thesametimestampsas those of the Diver.These data
pointsappear as values of 400 cmH2O and-20°C inthe barometricdatalogger data.
Thebarometric dataloggermemory isclearedwhen theDiver-Linkismoved to another monitoring
pointand/or project.
