Local network configuration
Within an Ethernet network (LAN, intranet, internet) every device is identified by an IP address (e.g.
192.168.250.20). The address can be either public or private (for example computers in a company
network have public IP addresses and a home computer with a connection to the internet via a web
provider has private IP address).
Before connecting the Ethernet cable the IP address must be set (manually or automatically) so as
not to be in collision with other computers in the network.
2.1
Manual setting of the IP address
Using a system keypad set a suitable IP address as given by a network supervisor. DHCP
(automatic assignment of IP addresses) must be disabled, see 3.1.
2.2
Automatically setting the IP address
Give your network supervisor the communicator's MAC address which can be found on the label on
the bottom part of the communicator or on the package box. The supervisor will provide you with an
automatically assigned IP address. DHCP must be enabled (see 3.1.).

Communicator configuration
Communicator configuration can be done via the system keypad (the control panel must be in
programming mode). To exit programming mode, press the N key. The following settings should be
done in consultation with the network provider / supervisor. Default settings and backup can also be
made by Locator software, which can be found on www.jablotron.com.
3.1
Automatic assignment of IP address (DHCP)
Before attaching the communicator to the LAN network, it is necessary to determine the assignment
of IP address. If DHCP is disabled it is necessary to set parameters according to sequences 3.2, 3.3
and 3.4.
940
941
Factory default: 941 – automatic assignment of IP address is enabled
3.2
IP address setting
If DHCP is disabled, set the IP address by sequence:
where:
NOTE: if some of digits are not used in the IP address, they must be substituted by zeros (see example)
Example: to set the IP address 192.168.1.23 enter 91 192 168 001 023
Factory default setting: IP address 192.168.1.253
3.3
Netmask setting
If DHCP is disabled, set the subnet mask by sequence:
where:
Example: to set Net mask 255.255.255.1 enter 92 255 255 255 001
Factory default setting: address 255.255.255.0
