iNode LAN – Instruction manual ELSAT s.c.
If DHCP off is selected, the fields IP address, Netmask, Gateway IP, DNS IP are active and
the addresses and values should be entered into them so that iNode LAN can work in the Ethernet
network. By default, DHCP is enabled, which means that all these network parameters will be
downloaded from the DHCP server, which is usually provided by e.g. an ADSL router.
The user can change the default device name in the HOST name field to any other name. It can be
up to 16 characters long. It is inadvisable, for example, to use different than English diacritical
marks because they can be misinterpreted by other network devices.
UpnP is disabled by default. The user can set the time after which it will be turned off after turning
on the power or reset, or turn it on permanently.
In BLE iNode LAN can work in one of the following modes:
1. AUTO SCAN – after powering, BLE environment is scanned in active mode and results are
sent to LAN using IP/UDP as multicast/unicast or broadcast frames. You can easily receive
them on any IP enabled device with any S like Linux, Windows or Android. A data
structure is something different from this given in iNode Serial Transceiver USB/UART.
This mode is switched off when other client is connected to iNode LAN. It can be for
example iNodeSetup.exe or iNode Thermo through TCP/IP or web browser websocket.
IP multicast is a technique for one-to-many communication over an IP infrastructure in a
network – defined by multicast group and port. For iNode- AN it is 232.0.1.1:20000.
Unicast messaging is used for all network processes in which a private or unique resource
is requested. In computer networking, broadcasting refers to transmitting a packet that will
be received by every device on the network. In practice, the scope of the broadcast is limited
to a broadcast domain. Broadcast a message is in contrast to unicast addressing in which a
host sends datagrams to another single host identified by a unique IP address.
2. REPEATER – after powering, device starts receiving from LAN IP/UDP frames sent by
other iNode LAN device or devices. If content of received UDP frame is correct then data
from them is sent to BLE environment as ADV_N NC NN_IND frame. iNode LAN does
not sent to BLE advertisement ADV_N NC NN_IND type.
3. AUTO SCAN / REPEATER – after powering, device starts to work in both above modes.
4. OFF – after powering, device is not active in any manner in BLE environment but still can
work with iNodeSetup (in AUT SCAN and REPEATER mode it is also possible). iNode
LAN has to be connected to the same LAN as a computer running iNodeSetup.exe
application. It should be automatically found and can be chosen by clicking at the picture
Using any telnet application like Hyper Terminal you can connect to iNode LAN at port
5500. It can work like iNode Serial Transceiver USB through C M port.
BLE Scan chose type of the BLE scanning – active or passive. In active mode iNode LAN sends
request to each scanned device so you should remember that this type of scanning can drain more
the battery of the scanned device. BLE IP address and BLE IP port determine a receiving server IP
address and port. iNode LAN will send to this server UDP datagrams with the received BLE data
frames (in AUTO SCAN mode). iNode LAN in REPEATER mode if multicast addressing is
used should have the same group and port settings like iNode LAN in AUTO SCAN mode. At
BLE RSSI you can set in dBm the threshold level for received BLE frames which exceeding
