First steps
In this chapter you will learn how to connect the IP WatchDog2 easily to your PC or company
network, setting it up and putting it into service.
Device connection
The following procedure is recommended for quick setup of the device. Detailed description of all
parameters and commands can be found in chapter called "Parameters description".
Cable connection
Set switches from DIP1 and DIP2 into OFF position.
Connect IP WatchDog2 to the Ethernet 10/100 Mbit network.
Connect the supplied power adaptor to power grid and plug the connector of the power adaptor
into power connector of the IP relay. The Power LED indicator should light up.
If the Ethernet connection is OK, the LINK indicator should light up.

Primary configuration of Ethernet parameters
The primary configuration of the IP WatchDog2 (IP address, network mask and gateway) can be
done via UDP Setup - IP WatchDog2 must be found on local part of ethernet network.
UDP Setup - Searching the device using UDP setup
Launch the program „HerculesSetup.exe,“
which can be found in root directory on
supplied CD. The latest version of the
program can be also downloaded for free
from our web pages www.HWgroup.cz .
In the UDP Setup“, tab, press the „Find
modules“, (step 1 see picture). The
device's MAC address should appear in
the left column.
Click on MAC adress (step 2). In the field
„Required parameters“, the configured
device parameters should appear.
Note: If you wish to change these basic
parameters (it is necessary to set at least IP
address, port, mas and gateway), enter
desire parameters into proper fields (3) and
press the „Set module“ (step 4) When
entering IP address and Gateway manually, it
is also necessary to disable assigning
DHCP by the server (clear Enable DHCP field)
Enter the IP address of the device into your
WWW browser The Main Page of www
interface will appear.
Detailed information on configuration
methods over www interface can be found in
the chapter called Device configuration via
WWW.

Device configuration via WWW
IP WatchDog2 contains a WWW interface allowing easy and detailed attendance of the device
activity. The interface consists of four HTML pages which can be called by entering IP address of
the device from your web browser.
IP WatchDog2 Main Page
After entering WatchDog2 IP address to the web browser you will get a main page showing the
basic parameters of WatchDog2 channels and statistics for the last 20 operations of each channel.
In the upper part of the screen you can see links for advanced properties configuration of the IP
WatchDog2:

Gateway - IP address of default gateway - assigned by the administrator of the network.
DNS Primary / DNS Secondary –IP address of DNS server –assigned by the administrator of the network.
HTTP Port - number of port, where the built in WWW server is listening - change the number to have more IP
WatchDog2 devices accessible from an external network via the router. Ask your network administrator about
any changes. The default port is 80.
Security section: Device Admin
Username / Password - username and password for security access to IP WatchDog2.
