DN-109NE, DN-119NE, DN-129NE and DN-189NE display series
4.
OPERATION
4.1.
Initial start-up
Before connecting the display to the network, we must ensure that all of the connections have
been carried out correctly and that the display is firmly in place.
Each time we connect the display to the power supply network, an initial reset occurs which
tests all of the segments comprising the display. The test consists of the sequential illumination of all
of the digits with the number "8", all of the digits with the value "0", all of the decimal points are lit up
and finally the version code. From this point any one of the following three situations may occur:
The display receives data from the Ethernet network and displays it.
The display does not receive data and the time without data equals zero. Continues to
show the decimal points.
The display does not receive data and the time without data is not equal to zero. After
a time without data it displays a dash in each digit.
4.2.
Parameter programming
Displays DN-109NE, DN-119NE, DN-129NE and DN-189NE can be adapted to the
specifications of each client by the programming of parameters. The parameters which can be
configured are:
1- Reserved Not used
2- End of block code
3- Time without receiving data
4- Response Message
5- Unit MAC code
6- Load the default configuration to the Ethernet port
Displays with color option
b- Activation conditions and timing of output/colour 1.
c- Value of the alarm 1.
d- Activation conditions and timing of output/colour 1.
e- Value of the alarm 2.
nr
– Colour if no relay is activated
r1 - Colour if bit r1 is activated
r2 - Colour if bit r2 is activated
r3 - Colour if bit r1 and r2 are activated
7- Exit modifying parameters
To program the parameters, the digits on the right of the display are used. The number of the
parameter is indicated by the digit on the left and the decimal point flashes while the digit on the right
is off.
