CHAPTER 3 OPERATION 3-1
DC-24 and DC-25 operation manual
3. OPERATION.
3.1. Initial reset.
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, the DC-24 displays show the active sensors (activated = 1, deactivated = 0)
and then the current temperature and the humidity
In the DC-25 displays, the version code is displayed until the first message with data is
received.
3.1.1. Displays with several sensors.
In the displays with several sensors, the displayed value is the mean value of the sensed by
the connected sensors,
The display detects the connected sensors and calculates the mean value depending on
the active sensors.
If when powering up there is no sensor dete
cted, “0” is displayed in the 5 digits. If once the
display is initialized there is no sensor detected, “E02” is displayed instead of the temperature
3.2. Programming parameters
Displays with connectivity options or analog inputs must be programmed previously to its
use. The parameters the user must configure are:
Displays with RS-485 serial line
1- Address of the display in the network.
2- Transmission baud rate, data bits, parity, stop bits.
3- Sensor control and communication control: ASCII, Modbus RTU-ASCII, Modbus
RTU-Word
F- Quit menu. Press
“*”
Displays with Ethernet and Wifi
1- Display the MAC address of the display
2- No use.
3- Sensor control and communication protocol: TCP/IP and Modbus/TCP
4- Reset communications port.
F- Quit menu. Press
