CHAPTER 5
PROTOCOL AND OPERATIONAL WORK
5-12
Displays of series DN-109NN, DN-119NN, DN-129NN and DN-189NN
The control commands available which allow you to blink displayed data and change
display color are the following:
08h
start of digits blinking (must be indicated before the first blinking digit)
09h
end of digits blinking (must be indicated after the last blinking digit)
Example: The next table shows some examples combining numerical values in ASCII
format and control commands (assuming the address range defined in Fig. 10)
(1) Monochrome or color equipment with red color set by default.
(2) The value displayed blinks.
(3) Configuring the color with the control command.
Automatic color control (Color option)
By means of color parameters we can define value intervals linked to a specified color
(Red, Green and Yellow). In this way, when the value represented is within the defined interval,
the value will be showed in the selected color.
As it was commented in section 4.2.3.4, two internal bits (r1, r2) are used as triggers for
the color representation. Each one of these bits uses two control parameters B, C for r1 and D, E
for r2. The parameters B and D define the activation condition for r1 and r2 respectively, and C
and D parameters assign the trigger value for these bits.
In the abovementioned section, the configuration values for each parameter are specified
in detail.
