ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device.To do so, touch a grounded sur-
face such as a radiator or tap!
ATTENTION! Short circuit!
A short circuit can lead to damage to electronic components!
ÎClose the housing before establishing the mains con-
nection!
If the mains adapter or its cable is damaged, it has to be replaced by an identical
mains adapter, which is available from the manufacturer or its customer service.

essary, extend the cable using the terminal block included and a common two-
wire cable.
2. Plug the mains adapter into a socket.
3. For a direct connection to a router or a PC, connect the Datalogger to a rout-
er  or a PC using the network cable (included with the DL2, ).
The cables carry low voltage and must not run together in a cable conduit with
cables carrying a voltage higher than 50 V (please pay attention to the valid local
regulations).

8.7 Conguringautomaticrmwareupdatequerysettings
The rmware is the internal software of the DL2 Datalogger. Through rmware
updates, the software will be improved in the following ways:
• Extended functional range
• Enhanced operation
• Customisation of the Web interface desktop
When automatic rmware updates are enabled (strongly recommended), the DL2
Datalogger will search for new rmware versions in regular intervals.
Note
Previous congurations are not affected by a rmware update.
Note
When there is no Internet connection, rmware updates can only be run
with an SD card.

9.1 Accessing the DL2 Datalogger over the Internet withoutVBus.net
Note
The DeviceDiscoveryTool cannot be used for nding a DL2 Datalogger
over the Internet.
The following preparations have to be made when a DL2 Datalogger connected to
the Internet via a router is to be accessed over the Internet:
• Assign a static address to the router.
• Carry out port routing in the router.
Assigning a static router address
In order to access the router and the DL2 connected over the Internet, a static
address has to be assigned to the router.
There are 2 different ways to assign a static Internet address to the router:
• Over a dynamic Domain Name Server (DynDNS)
• Over a static Internet IP address

Note
Not all routers support DynDNS services. For further information consult
the router documentation.
It is possible to reserve an Internet address via a DynDNS service provider. Dy-
nDNS services are usually free of charge.
Schematic process representation of using a DynDNS address:
1. Open an account for a DynDNS Internet address at a DynDNS service provid-
er.A DynDNS Internet address and the corresponding access information will
be provided.
2. The DynDNS access information has to be entered into the router, so that the
router can tell the DynDNS service provider where to route enquiries to.
3. In order to access the router via the Internet, the user has to enter the Dy-
nDNS Internet address into the Internet browser.
Using a static Internet IP address

It is possible to apply for a static Internet IP address at an Internet Service Provider
(ISP). For a static IP address, there usually is a fee required.
Schematic process representation of using a static IP address:
1. Apply for a static IP address at an Internet Service Provider (ISP). A static Inter-
net address and the corresponding access information will be provided.
2. The access information has to be entered into the router, so that the router
can register at the ISP with the static IP address.
3. The router registers at the ISP with the static IP address.
4. In order to access the router via the Internet, the user has to enter the static
Internet address into the Internet browser.

Port routing in the router
Note
Not all routers support port routing. For futher information consult the
router documentation.
In order to access, over the Internet, one or several Dataloggers connected to one
router, port routing has to be congured in the router.
The DL2 Datalogger communicates via the following ports:
• Web interface port: 443 (adjustable, default port: 443)
• RESOL RPT Parameterisation Tool/RESOL ServiceCenter port: 7053 (non-ad-
justable)
In order to carry out port routing in the router, proceed as follows:
1. Assign a static LAN IP address to the DL2 Datalogger using the conguration
menu of the router.
2. Assign a port to the IP address menu using the conguration menu of the
router.
In this example (see table below), 3 DL2 Dataloggers are assigned 1 Web interface
port and 1 RESOL ServiceCenter software port each.
See chap. 9.3 Logmodeconguration, page 19.
The Log interval determines the interval in which the DL2 Datalogger logs data.
Note
Log intervals between 1 second and 86400 seconds (24 hours) are pos-
sible.
Note
The smaller the log interval, the more memory capacity is used.

9.3 Logmodeconguration
The Log mode determines how the DL2 Datalogger behaves when its internal
memory capacity is fully used.
There are 2 different settings possible for the log mode conguration:
• Cyclic logging (factory setting): When the memory capacity is fully used, the old-
est data are overwritten.
• Linear logging:When the memory capacity is fully used, data logging stops.
In order to congure the log mode, proceed as follows:
1. In the main menu DeviceCong, select the submenu General.
2. On the Logging Conguration tab, in the Log mode dropdown menu,
select the desired value.
3. Click Saveconguration.
