2OVERVIEW AND PREPARATION FOR USE
2.1 LOGGER -DEVICE OVERVIEW
The Multilog2WW logger
family is flexible in design
and can be built to suit a
variety of uses.
An example is shown
opposite.
Your logger may be different
to the one illustrated; several
models exist within the
Multilog2WW family.
The loggers are of a
waterproof construction and
have waterproof connectors
for attaching the sensors and antenna.
The connectors can exit the unit via
either the top or bottom of the case.
The logger includes 4 key-hole
shaped mounting lugs,
(spaced 300mm x 157mm apart).
The logger may be fixed to a wall using
flat-headed screws using the holes.
There are 3 additional holes passing
through both sides of the case; these
can be used for applications requiring
anti-tamper seals to be applied.
The top surface of the unit can be
identified using the shape of the
keyholes.
It can also be identified from one of
the labels on the front of the unit.

2.2 PREPARING A LAPTOP PC (OR SIMILAR DEVICE)FOR USE WITH LOGGERS
The logger devices require a user-interface in order to setup and test the unit. This is
provided by means of a HWM software tool which is to be installed onto a Personal
Computer (or similar device). The PC must have a USB port and Internet capability (for
occasional use).
The required software tool is “IDT” (PC version). This runs under the Microsoft Windows
operating system. To install IDT, follow the instructions within the IDT user-guide (see
also section 2.5.1).
The installer is required to be familiar with the use of IDT (PC version). Refer to the
relevant section of the IDT user-guide for guidance during setup of the Multilog2WW
logger.
2.3 LOGGER OPERATION
The logger is powered by a non-rechargeable Lithium battery. The software is designed
to minimise battery use and thereby prolong the expected battery life. However, battery
life is also affected by user-programable settings. The user is advised to set the logger to
keep tasks and sample frequencies to the minimum requirements of the intended use
in order to manage battery power effectively.
The unit can also operate from an (optional) additional external HWM
battery unit (see opposite); various battery sizes are available.
Where supplied, the external battery power is used to extend the
battery life of the system or for more frequent communications with the
host server.
The logger is normally shipped from the factory in an inactive state
(referred to as “shipping mode”) to preserve the life of the battery.
When activated (see section2.5.4), the logger will go into the state of “Recording” and
begin repetitive logging of the various sensors fitted to the unit, according to its
configuration and settings.
The logger can operate using two time periods, known as the “sample period” and also
the “log period”. It will sample the sensors at the sample rate to create temporary
measurement samples; this is a repetitive background task. After taking several
measurement samples, some statistical functions can be optionally applied to produce
a datapoint that is logged (saved) at the log rate; these form the recorded (logged)
measurements and are saved into an area of memory which is referred to as the
“primary recording”. The log period is always a multiple of the sample period.

If the logger has the feature enabled, it can also be set to occasionally save additional
data into a “secondary recording” memory area, (e.g., data sampled at a higher
frequency).
Note: This is not available on all supplied units and must be arranged through your
sales representative before placing an order; it has implications concerning
expected battery life of the unit).
In addition, the logger will have daily tasks at set times, such as uploading its un-sent
data over the internet. When sending data, the logger waits to receive confirmation
from the server that the data was received without error; If confirmation is not received,
it will re-send the data at the next call-in time.
The logger can be programmed to monitor data for certain patterns or conditions and
can send a message if it should detect a match. Commonly, this is used for setting a
condition that can be an indication of an “alarm”. The message can be sent to either the
server (the usual destination) or another device.
An installer can also download a local copy of the data to a PC using the IDT software
tool. IDT can be used to inspect the data on-site, or it can also be used to forward data
to the server (e.g., If the logger has been unable to make recent contact with the server).
Refer to the IDT user-guide for details of its possible uses. The IDT user-guide also
provides an introduction to basic, general-purpose, logger operation; this may provide
further information.

2.4 SERVER INTEGRATION –STORING AND VIEWING DATA
The logger includes an interface (referred to as a modem) that provides access to the
internet via the cellular mobile communications network. A SIM card is used to give
access of the network.
Measurement data is initially stored within the loggers, until the next call-in time. The
data can then be uploaded to the server using an encrypted format. Typically, the server
used to receive and store the data will be a HWM DataGate server, although other
servers may be used in conjunction with HWM software.
The logger data may be viewed using a viewing portal which has access to the data
stored on the server. (Refer to the relevant user guide for details of how your data
viewing can be used to view the logger data).
2.4.1 DataGate Server / Data viewing portals
When integrated with HWM’s DataGate server, the logger’s measurement data can be
stored centrally and made available to users via a viewing portal (website).
The data can be viewed remotely / graphically by anyone with a suitable user account
(and password) using a standard web-browser.
DataGate can also forward any alarms received from the unit to all users that have
subscribed to them; one logger alarm message can be distributed to multiple DataGate
users.
DataGate can also (by arrangement with your sales representative) be used to export
logger data to other servers.
Some administrative setup of the server and the viewing portal is normally required to
facilitate receiving, storing, and presenting logger data correctly. These topics are not
covered by this user guide.
Depending on the type of sensors used with the logger your data may be alternatively
viewed via a dedicated website which is designed to better present data from the
sensor. Refer to the sensor user-guide or IDT app user guide to see if this is appropriate
or discuss with your HWM representative regarding which viewing portal to use.
(For illustration purposes only)

2.5 COMMUNICATING WITH THE LOGGER
To communicate with the logger, a PC is required, along with a HWM software utility
called “Installation and Diagnostic Tool”, or more commonly known as IDT (PC version).
Note: There is another version of IDT, the IDT (mobile app version).
The app version of IDT is not compatible with this logger device.
2.5.1 Download of IDT (PC version)
IDT (PC version) and its user-guide can be downloaded from the HWM Customer
Support website, or from the following webpage:
https://www.hwmglobal.com/idt-support/
Note: The user has to be registered by HWM and have a password to gain access).
Refer to the IDT User-guide for information on how to install and use the tool.
2.5.2 Connecting the comms cable
A communications cable is required to connect the logger to a USB port of a PC.
The interface for the communications cable
on Multilog2WW is normally positioned at
location “T2” and is shared with the connector
used for any external battery. (Normally a
cable with a 6-pin connector is required, but
certain models may use a 10-pin connector).
Where no external battery is connected, a straight cable is required. Attach the
communications cable to the Comms interface.
Where an external battery is fitted, it is advisable to use the ‘Y-cable’ version of the
programming cable, which is temporarily inserted between the battery and logger
Comms connector. Its use is recommended due to some sensors requiring additional
power that is provided by the external battery pack.
Plug the USB end of the programming cable into a standard USB port of a PC.
It is now possible to communicate with the logger using IDT.
(Contact your HWM representative to discuss any programming cable requirements).
Remember to re-connect any external battery when finished.
