Introduction
Thank you for choosing an HWM data logger(s), we trust it will provide you
with many years of service.
The individual configuration of your logger(s) may differ slightly from the
detailed descriptions that follow, but any additional setup information that you
need, can easily be obtained from our customer support team.
Unpacking
As you unpack your new logger, please confirm that you have the following
parts required to install the equipment. If there are any omissions, please
contact our sales team to rectify or supply the missing parts.
•Multilog LX GPRS data logger
•Radwin Software CD-ROM (also available at www.hwm-water.com)
•External GPRS Antenna (optional)
•IR Reader (optional – available in serial or USB types)
•Connection cables (optional)
•Connection hose for a pressure logger (optional)
•External battery and appropriate cable (optional)
•Hanging bracket for external battery and logger (optional)
Please dispose of your waste packaging responsibly.
Before proceeding to site for physical installation, please take the time to
configure your logger in an office environment. Most settings can be
configured before visiting site and this will save time at the point of install,
especially if the weather is bad.
You will need to have:-
A valid HWM DataGate™ account with appropriate username and password.
See DataGate™ setup later in this manual.
A PC with Windows 7 installed (Radwin also supports Windows XP & Vista)
A USB to Serial adaptor (if required to use with serial IR reader).
A description and reference number for the installation site:
The reference number is split into a Zone and Location format to allow
for grouping of individual “Locations” into larger regions or “Zones”.
The format of the number is configured during the initial installation of
the software but essentially is a 7 character code, e.g. AB123CD
The SIM card installed into the logger and a good GPRS signal on site for the
chosen network (Roaming SIMs are also available):
This is already done for you if you ordered a data package with the
logger.
See appendix A if you have purchased a data pack & SIM separately.

First time run of Radwin
Once you have installed Radwin you need to make some initial setup choices
and configurations.
Creating your first Database
1. From the start menu, click <<All
programs>> and find the program group
“Radlog for Windows”
2. Click <<Radlog for Windows>> to expand
the group and then click <<Radcom
View>>
You may wish to “Pin” the program to your
taskbar for convenience. To do this, right
click on the Radcom View icon and select
“Pin to Taskbar” from the pop up menu.
The program can now be conveniently
started from the taskbar.
3. After the program starts you will be automatically prompted to set up a
new database path
This is for local storage of configuration information and any data that
you may directly download from the logger or from DataGate™ after
site installation.


8
A note about Logger Identity Selection Method:-
A logger is identified with a single 7 digit
reference ID.
If you select Single Identity from the menu
then you can use the full 7 digits how you like.
E.g. account no, customer number, etc.
However, when installing a larger fleet of loggers, Radwin allows you to
group individual logger Locations into larger Zones. This allows for
geographic regions (Zones) to be easily indexed where large fleets are
involved.
So, Locations refer to loggers
Zones contain Locations (loggers)
Many Zones may be created
Each Zone may contain many Locations (loggers)
For example, split a town up into Zones then split the Zones up into
Locations and deploy loggers within each Zone.
If you choose this (default) option you will be prompted (later on) to
decide how the 7 digits are allocated. E.g. ZZ/LLLLL means you can
have up to 99 zones with 99,999 loggers in each zone, or ZZZ/LLLL
gives 999 zones with 9,999 loggers in each and so on.
In this way you can develop an indexing method to allow you to quickly
find sites you wish to examine.
4. From the Logger Identity Selection
Method, choose the option as
described above.
If you wish to change to location of the folder
where the database is stored, click
<<Browse…>>
Then navigate to the desired folder and click
<<Open>> to choose the folder.
When prompted below click <<Yes>> to confirm the folder choice.



5. Now click <<OK>> to create the database.
If you chose Zones and Locations in step 4,
chose your format for the ID number. The
default is the UK postcode format, e.g. AB12
3CD
Then click <<OK>> to continue.
Note: The Database format CANNOT be changed from this point. If
you need to change it later you will need to delete the \DATA folder and
start again.
If you have upgraded to this edition of Radwin from an earlier version,
then the database format that was chosen in the previous edition will
be maintained.

Setting up the communications cable
Note: The following instructions assume the use of the USB IR Reader
connected to a PC USB port or a Serial IR Reader connected to a PC serial
port.
1. Connect the USB plug to a spare USB port on your computer or the
Serial plug to a spare Serial port on your computer.
2. Position the reader head on the logger as shown below
Take care to position the
head over raised ring area
around the window. The
reader head will hold onto the
logger by magnets in the ring
around the window and this
helps with positioning.
3. Start Radcom View again (unless already running) and from the menu
select <Configuration> and then <Advanced Configuration…>
4. The menu below shows details all the setup functions available to
Radwin, for the Communications port configuration click the <<Manual
Call>> item from the list.

11
5. The Manual Call menu now appears, from the Direct Cable Port
dropdown list pick the COM port that you will be using.
A note about COM port choice:
In the example above of a Laptop, you can see 3 COM ports listed, the
numbers and descriptions vary from PC to PC but to summarise the
types:-
•RIM Virtual Serial Port (e.g. COM1:) should be ignored as
Radwin will not communicate via these types of ports. These
often have high COM numbers (above 10).
•USB Serial Port (e.g. COM2:) is a genuine COM port that can be
used with Radwin and is usually the USB Reader cable.
•USB to Serial Bridge (e.g. COM4:) is also a genuine COM port
that can be used and is generally a USB to Serial adaptor cable.
If you are using a Desktop computer or a Laptop with a docking station,
you may also see a Communications Port. This is also a valid choice
for your Direct Cable Port, however there is usually more than one so
check the physical indication by the socket on the back of the
computer.
Tip: If you are using a USB connection, you can check you have the
right one as follows:-
i. Look down the list and note each COM number that is not
empty.
ii. Click <<Cancel>> to close the System Configuration menu.
iii. Remove the USB plug from the PC.
iv. Repeat steps 3 to 5 above and look for the one that has
disappeared. This is the COM port you need to select in step 5.
v. Click <<Cancel>> to close the System Configuration menu
again.
vi. Reinsert the USB cable IN THE SAME PORT AS BEFORE and
repeat steps 3 to 5, selecting the COM port noted in step iv
above.


12
6. There is no need to configure any other ports at this stage.
Click <<OK>> to save the configuration.
7. Congratulations, you are now ready to begin configuring your new data
logger.

13
Programming your first logger
With the logger connected to the computer as in the previous section, you
now need to run the configuration wizard to set your logger ready to send in
data.
Using the Configure Logger wizard
1. If you have not already done so, run the “Radcom View” program.
2. From the menu, click the
button to launch the
programming Wizard
3. Radwin now needs to know the type of logger you are using. You can
either select this from the Logger Type drop down menu
or click the <<Auto Detect>> button to allow Radwin to discover the
type automatically.
Then click <<Next>> to continue.
4. You need to tell Radwin how the logger is currently connected to the
computer. As you are physically connected to the logger, choose the
default type, “Direct (Cable)”
then click <<Next>>

14
5. You are now ready to download the current settings from the logger,
so click <<Next>> to continue.
6. Radwin will now retrieve the current settings from the logger,
7. You now are able to give your logger a unique identity
Enter the details in the four
fields according to your chosen
Zone and Location plan as
described on page 8 and then
click <<Next>>.
8. You now need to define how the logger will transfer its data. For this
DataGate™ setup, you go with the default setting, GPRS,
so click <<Next>> to continue.

15
9. Each logger must have a unique Telephone number. If you are using
your own SIM card enter its number here in international format;
otherwise the Telephone
number of the SIM card
supplied in the logger will
be automatically entered.
Click <<Next>>
(Answer <<Yes>> to the
warning if prompted)
10.You now need to configure the channels (1 channel per signal/sensor)
that you wish to use.
A note about logger channels:
The Multilog LX is available in several different configurations for
Pressure, Flow and other sensors. Data is presented to the viewer in
Channels and Channel numbers are allocated in the factory by priority
of sensor type. So, where fitted, analogue sensors, e.g. Pressure
transducers, Depth measurement devices and 4-20mA flow sensors,
will always come through on CH1 and digital inputs, e.g. pulse
counters, will take any remaining channel numbers.
Radwin automatically detects the configuration of the logger and will
prompt you according to the type of Transducer appropriate to that
input.
The following example will set up 1 pressure transducer and 1 flow
channel for a logger configured in the factory for 1 pressure and 2 x
unidirectional flow.
For more specific details on other variants or if you experience
problems, please contact HWM support.
11.The Channel 01 configuration menu appears as below:-
j To turn ON the Pressure
channel, tick the
“Enabled” box.
The default transducer is
for a pressure transducer
with a Calibration factor of
0.1. If you are configuring
any other type of sensor,
please refer to HWM
support.
Click <<Next>> to continue.


16
12.The Channel 02 configuration menu appears as below:-
Again, tick the “Enabled” box to switch the channel ON.
Choose how the logger
will measure pulses from
the dropdowns, “Count”
counts each pulse
received by the logger,
“Event” converts the time
between pulses for slow
flow rates.
If you do not wish to count
every pulse for high rates,
choose “Every nth pulse”.
.
13.As you are configuring a Digital pulse input, you need to configure the
number of Units Per Pulse to match the output from the Pulse Unit on
your meter. Check your meter for these details Click <<Configure>> to
select your transducer type.
From the drop down list,
choose the pulse rate or
sensor type that matches
the Pulse Unit that is fitted
to your meter.
Then click <<OK>> to
store this setting and
return to the channel
menu.
C Click <<Next>> as in step
11 to move to CH3.
Note: You can also enter the pulse rate manually, simply click in the
Unite Per Pulse box and enter the value, take care over the decimal
place.

17
14.For Channel 03, leave the “Enabled” box un-ticked to leave the channel
switched OFF.
Click <<Next>>
Note: If you leave an unused channel Enabled (ON) you will simply see
flatline data on the viewing platform.
15.Next you need to specify the Sample Rate that you require.
In most cases the
default setting of 15
minutes will be sufficient,
however, if you wish to
change the rate, simply
select a period from 1m
to 24hrs from the
dropdown menu.
Click <<Next>> to move
on.
A note about Sample Rates:
•For a digital input (e.g. flow), the sample rate equates to the
number of pulses counted during the period set. So, if 900
pulses were counted over the 15m sample rate set above, this
equates to 1 pulse/sec and if you have set 10ltr/pulse in step 13,
then the final result is 10litres/sec.
•For an analogue input (e.g. pressure, depth, etc.) the logger
takes a background measurement every 30 seconds (or the
sample rate, whichever is smaller).
This background measurement is then averaged across the
sample period selected. So if you set a 15m “Sample Rate”
above, then the logger will record the average of the 30 readings
taken during the 15m period selected.
If you choose a sample rate faster than 30s, then the
background sample period with adjust automatically to match it,
however this will reduce battery life.



18
16.You now need to choose how the logger is to record data.
If you wish to Start
recording from a specific
time, enter the “Start
Time” here.
If you wish to Stop
recording at a specific
time, tick the
“Enable Stop” box and
enter the time you wish
to stop recording data
here.
Choose between “Cyclic Memory” or “Block Memory” by clicking on
either of the two buttons here.
“Cyclic Memory” means that when the logger’s memory becomes full, it
continues to record new data by overwriting the oldest data first.
“Block Memory” means that when the logger’s memory becomes full it
simply stops recording and any new data will be lost.
Note: In most cases where the logger is calling into a central system
via a communications network, the default settings will be correct.
(No Stop Time and Cyclic memory).
If you do not specify a start time, then the logger will start recording as
soon as the Wizard completes.
17.Click <<Next>> to continue.

Configuring the Data Transfer Settings
In the following steps, it is assumed that the logger being installed is a
standard DataGate™ (HWM data warehouse) installation. If you have a
bespoke data warehouse, the communications address may be different.
Please obtain these settings from your HWM account manager.
18.In most cases the settings will have been already programmed into the
logger at the factory. GPRS UDP is the
type of
communication
protocol used with
DataGate™ for Data
and Alarm transfer.
[1] UDP… is the
internet address
where data from the
logger is delivered.
This number is
where SMS (text)
messages are sent (once per day) in the event that a GPRS
connection has not been made during the previous 24hours. The
example above shows the DataGate™ number, for other data
warehouses please refer to your HWM account manager for this
number.
Note: If you have a different UDP address to enter into the logger, click
the button <<[1] UDP:…>>
Here you can now enter the internet address and port number for the
data warehouse you are using. Click <<OK>> to confirm.
If you wish the logger to send data to two different addresses, click the
<<[2] UDP:…>> button and enter the details for the second warehouse
as above.
Please be aware that sending data from the logger to two different
addresses will increase your data usage as two separate messages
will be sent, it is more data (and cost) efficient to send the data to one
warehouse and have it forwarded to the second via land based
connections.
Your HWM account manager can help with such requirements.


20
19.The GPRS Call Times allow you to choose how often the logger will
attempt to contact the data warehouse. There are 4 different modes
available for data call timing.
Choose the desired “Call
Times” mode from the
dropdown menu, and then
double click on the call time
that you wish to adjust.
Note: the 2 different addresses specified in step 18 can be configured
separately. Double click the second clock “[2]” to enable the logger to
send data to the second address.
Don’t forget to tick the “Enable” box to turn the timer ON.
Call Time Modes
i. “Call Frequency” mode (Factory Default – 12hrs, 2 calls/day)
In this mode you simply specify how many minutes pass before
making the next data call. Choose your desired frequency
from every:
5 minutes (480 calls/day) to
12 hours (2 calls/day)
then click <<OK>> to store
Note: Maximum is 3 calls/day without an external battery.
ii. “Dual Call Frequency” mode allows you to specify 2 different call
in rates for 2 different time periods of the day. E.g. a lower rate
during the night.
Choose your desired main
frequency (as above).
Then choose the secondary
frequency.
Next choose the time that the
secondary rate will start.
Finally choose the time when the
secondary rate will stop. Click
<<OK>> to store.
In this example the logger will send in data every 15 minutes
during the day but only once per hour between 18:00 and 02:00
in the night. This helps to reduce data costs.
