Parameters of radio links:
•Sensitivity: -100dBm,
•Power output of transmitter: 10dBm,
•Working frequency: 430 ... 440MHz,
•Number of radio channels: 10
•Sort of modulation: FSK,
•Transmission speed: 19 200 b/s,
Predictable working range :
•no built-up area - up to 200m,
•poorly built-up area - up to 100m,
•densely built-up area - up to 50m,
The range will decrease under the influence of industrial disruptions and is
dependent on characteristics of installation place e.i. area conditions, level of
installation, distance from large metal surfaces, thickness and wall materials.
Logging parameters of radio data logger:
•Time of data storage for slow temperature and humidity changes (e.g.
cooler):
oto 29 years (all sensors totaly),
•Time of data storage for frequent temperature and humidity changes (e.g.
sunny places):
omin. 356 days (totaly ditto)
•Frequency of data logging: every 1 minute
To add data logger and to add LGRT-02 to the system you have to login
as an administrator use “Adm” as login. Then set present date and time in data
logger. You must check data logger, which you install in “Data logger list”
window and press the button “Set date”. If displayed data and time is different
from system date you should update by pressing “Set date and time” button.
