Included with the DL2:
Datalogger DL2, ready to plug in,•
with mains adapter and RESOL
VBus®-cable
Network cable, 1 m•
Wall plugs and screws•
Terminal block (for extending the•
RESOL VBus® -cable)
This additional module enables the acquisition and storage
of large amounts of data (such as measuring and balance va-
lues of the solar system) over a long period of time.The DL2
can be configured and read-out with a standard Internet
browser via its integrated web interface. For transmission
of the data stored in the internal memory of the DL2 to a
PC, an SD card can be used.
The DL2 is appropriate for all controllers with RESOL
VBus®. It can be connected directly to a PC or router for
remote access and thus enables comfortable system moni-
toring for yield monitoring or for diagnostics of faults.

2.1 Mounting
The unit must only be located in dry interior locations. It is
not suitable for installation in hazardous locations and should
not be placed close to any electromagnetic fields.
Please pay attention to separate routing of sensor cables and
mains cables in order to avoid interferences.
Choose a mounting place«
Drill two holes (Ø 6mm) next to each other at a di-«
stance of 113 mm and insert the enclosed wall plugs.
Attach the base by means of the enclosed screws«
(4 x 40 mm) (1).
2. Installation WARNING!
Always disconnect the device
from power supply before opening
the housing!
2.2 Connection
(1)
Connect the datalogger (pos.1) to other modules in
the following order:
Connect the data cable (RESOL VBus«®, pos.3) to the
RESOL controller (pos.4). Extend, if necessary, with en-
closed screw terminal and (twisted) two-wire cable.
Plug mains adapter (Pos.2) into the mains socket.«
For direct connection of a router or PC, connect the«
datalogger to the router (pos. 7) or PC (pos. 8) by
means of the network cable (enclosed, pos.6).

3. Operation
The status LED (integrated into the button) visualises the
operating state of the DL2.
The datalogger can be configured, read out and deleted via
the integrated web interface.The DL2 is additionally equip-
ped with a manual reset button.The following functions can
be carried out by pushing the button:
Deleting the internal memory; the settings will not•
be deleted. For this purpose, press the button for
more than 5 but less than 10 seconds. All LEDs will
be flashing.
Resetting the datalogger to the factory settings. For this•
purpose, press the button for more than 10 seconds.
All LEDs will be illuminated. This reset process can take
several minutes.

4. Data transfer
Note
The SD card is not used for increasing the
internal memory capacity. It is used for data
transfer only.

6. Connecting the datalogger
The datalogger is designed for direct connection to a PC
via a LAN connection or a router and is used for remote
access. Please carry out the following steps:
1. Install the search tool:
The search tool can either be started from the
CD (DL2DiscoverToolSetup.exe) or from the
Internet (http://www.resol-dl2.de/discover/)
(Confirm the security enquiry about the digital signature)
5.2 Fill level of data memory The fill level LEDs visualise the current fill level of the data-
logger, i.e. the internal memory capacity used.
One bar corresponds to 10 % of the internal memory
capacity: Permanent illumination means that the memory
capacity is fully used. Flashing LEDs indicate the level at
which data are being stored.
Example:When the third bar from the bottom is flashing, the
capacity used is larger than 20% but smaller than 30 %.
Note:
When the DL2 is used in conjunction with a
Gigabit-Network device (laptop, switch, etc.),
problems can occur when the connection is being
established. In this case, we recommend using a
100 Mbit-switch between the two devices. It is
also possible to change the network properties
to “10 MBit/s half duplex” (see below).
In order to start the DL2-Discover-Tool, Java
version 6 or higher is required.
6.1 Access via LAN
Example:Changingthenetworkproperties
The settings option of the network properties can vary.The
following steps are used as an example only:
Select the connection by double clicking on the corre-«
sponding icon
Select the “General tab” and click on the “Properties”«
button
Click on “Extended” and set the media type to “10«
MBit/s halfduplex”

2a. Starting the tool from the Internet:
The datalogger will automatically be searched and dis-
played as soon as it is found by the search tool.If several
dataloggers are found in the local network, they will be
listed in the “RESOL devices found” list.The name men-
tioned in this list is the device name which can be set on
the “General” Configuration page of the web interface.
2b. Installation from the CD:
Start “DL2 DiscoverToolSetup.exe”. The search tool«
will be installed under “Programme\RESOL\DL2Dis-
coverTool”
Start the DL2 Discovertool. The DL2 will automatically«
be searched and displayed as soon as it is found by the
search tool. If several dataloggers are found in the lo-
cal network, they will be listed in the “RESOL devices
found” list. The name mentioned in this list is the device
name which can be set on the “General” Configuration
page of the web interface.
Mark the datalogger found by the tool by clicking it«
Click “Open”«
3. The standard web browser opens
Enter username and password. Username and pass-«
word are “admin” (factory setting).
For accessing the DL2 via Internet, the router has to be
setup first. For setup follow the following steps:
6.2 Access via Internet
Note:
The discover tool is not usable for DL2 access.
The IP address must be known. Either a static IP
address is used or a dynamic domain server has
to be used.
Since the IP address usually changes every day, it
is recommend to use a dynamic Domain Name
Server (Dyn DNS). For further information on
detecting a Dyn DNS, please see corresponding
documentation.
