Parameters Ethernet and Wifi.
3.4.1.
Parameter 1 for Ethernet and Wifi: MAC address of the display.
To know the MAC address, access parameter 1 and, using
the “*” key, access the 3 last values
of the MAC address. The first 3 numbers are always 00 -20 - 4A, so the first value displayed in
the parameter is the 4
th
value of the MAC.
3.4.2.
Parameter 2 for Wifi: Load the IP configuration through the RS-232 port.
To access the serial port for the first time, the RS-232 serial port and the Hyperterminal
(or a similar program) must be used. See paragraph 4.7.1 for more information.
3.4.3.
Parameter 3 for Ethernet and Wifi: Sensor control and communication
protocols.
This parameter performs two functions
Left digit: Sensor control
0-> Disable sensor information
1 -> Enable sensor information
Right digit: Communication protocol,
The user can select between the following protocols:
0: TCP/IP: Really simple protocol that uses ASCII characters
1: ModBus TCP: This uses the ModBus protocol, the temperature and humidity
data are coded in ASCII or integer in the same block.
In the display that receives the data through serial line (DC-25), the sensor information must be
disabled.
3.4.4.
Parameter 4 for Ethernet and Wifi: Load the default port configuration in the
Ethernet or Wifi port.
To load the default values in the communication port, program the value 99 and press the “*” key.
During the load time, the digits “99” are flashing. When it has finished, the parameter 4 is displayed
again.
3.4.5.
Parameter F: Exit menu.
Press the key “*” to exit the parameter menu. Before exiting the parameters are saved.
