2 Ethernet Communication
In addition to serial communication via the built-in RS232- and RS485 interfaces,
Lauer Navigation Monitors also support Ethernet communication for remote con-
trolling, device configuration and firmware update.
For a wide range of software support, the firmware includes standard network proto-
cols such as TCP/IP, HTTP, UDP and WINS. The main communication channel
uses UDP (User Datagram Protocol), which is a connectionless and simple protocol.
Using broadcast addressing, Lauer Navigation Monitors can be accessed within a net-
work without complicated configuration, or even automatically detected with simple
software support. Once connected to the device, detailed configuration data, such as
IP address or subnet mask for TCP/IP communication, can be queried by using the
special Lauer command set.
SCOM packets are encapsulated within UDP packets. For the UDP communica-
tion, two configurable UDP ports are used to send and receive data.
The following network protocols are supported:
Protocol Description Configuration Default factory setting
UDP Connectionless
protocol used as
the main
protocol for
communication.
The UDP ports can be
configured using the built-in
HTML configuration pages.
Current UDP settings can be
queried using the Lauer
command set.
UDP receive port:
10000
UDP send port:
10001
Please refer to section UDP for details.
TCP/IP Supports high
level protocols,
such as HTTP. A TCP/IP address and the
corresponding subnet mask
can be assigned dynamically
or statically.
Static and current TCP/IP
settings can be queried using
the Lauer command set.
Static IP-address:
192.168.0.1
Static subnet mask:
255.255.255.0
Please refer to section TCP/IP for details.
HTTP Provides HTML-
based
configuration
pages, exposed
through the
integrated web
server. No separate configuration can
be made, except for password
configuration, since the
protocol is stacked above
TCP/IP. HTTP port:
80
Password:
admin
Please refer to section HTTP for details.
WINS Allows using a
unique name
(host name),
mapped to an IP-
address. No configuration can be made,
except for the host name that
can be changed.
The host name can be queried
using the Lauer command set.
Host name:
LAU+[last two bytes of
the MAC-address as
ASCII coded
hexadecimal value]
Please refer to section WINS for details.
