Chapter IX Precautions for Use
1.
This station should not be operated in the vicinity of flammable places (such as coal mines) or explosive dangerous objects (such
as detonators for detonation).
2.
A suitable DC regulated power supply should be selected, which requires strong anti-high-frequency interference ability, small
ripple, and sufficient load capacity; it is best to have over-current, over-voltage protection and lightning protection functions to
ensure the normal operation of the data transmission station.
3.
Do not use in a working environment that exceeds the environmental characteristics of the data transmission station, such as high
temperature, humidity, low temperature, strong electromagnetic field or dusty environment.
4.
Do not leave the data station continuously at full capacity, as this may burn out the transmitter.
5.
The ground wire of the data transmission radio should be well connected with the ground wire of external equipment (such as PC,
PLC, etc.) and the ground wire of the power supply, otherwise it is easy to burn the communication interface; do not plug in or
unplug the serial port with electricity.
6.
When testing the logarithmic radio station, a matching antenna or 50Ω dummy load must be connected, otherwise it is easy to
damage the transmitter; if the antenna is connected, then the distance between the human body and the antenna is best more than
2 meters to avoid injury, and do not touch the antenna during transmission.
7.
Wireless data transmission stations often have different communication distances in different environments, and the
communication distance is often affected by temperature, humidity, obstacle density, obstacle volume, and electromagnetic
environment; in order to ensure stable communication, it is recommended to reserve more than 50% of the communication
distance margin.
8.
If the measured communication distance is not ideal, it is recommended to analyze and improve the communication distance from
the antenna quality and antenna installation method. You can also contact support@cdebyte.com for help.
9.
When selecting a power supply, in addition to retaining 50% of the current margin according to the recommendation, it should be
noted that its ripple should not exceed 100mV.
