B. Communications
The
MWM
can be connected by
USB
or ethernet (
TCP/IP
). From the user and
device perspective the two are equivalent, but if possible, use a network
connection for improved response times and faster data acquisition.
B.1
TCP/IP
When ethernet is connected, the
MWM
will attempt to obtain an
IP
address
by
DHCP
. If
DHCP
fails, an internally defined address will be used. In both
cases, the address will be shown on the device display, something like:
10.1.1.180:7802
The dotted-quad number (10.1.1.180) is the device
IP
address; you can
type that into the address bar on your web browser and you will see a
simple webpage for the device (via the standard
http
port 80).
The second number (7802) is the
TCP/IP
port number. This port provides
full access to device functionality. It is through this port that your control
software should access the device. Simple commands can be sent to the
device using the
telnet
protocol, for example:
telnet 10.1.1.180 7802
disp,rgb,100,100,100
Here the
telnet
command line sepcifies IP address 10.1.1.180 and port
7802. You can also use a GUI
telnet
, in particular on Windows
TM
we
recommend
PuTTY
available at
. Specify the
Host Name
as 10.1.1.180,
Connection type
as Telnet, and the
Port
which is normally
22, should be changed to 7802.
The above example sends the
disp,rgb
commmand to the device (to set
the display backlight intensity). The full suite of commands is described
in appendix D.
