11 Application notes

1. The device may not be operated in the vicinity of some flammable places (such as coal mines) or explosive
dangerous objects (such as detonators for detonators).
2. Appropriate DC stabilized power supply should be selected, which requires strong anti-high frequency
interference, small ripple, and sufficient load capacity; it also has functions such as overcurrent, overvoltage
protection and lightning protection to ensure data transmission.
3. Do not use it in a working environment that exceeds the environmental characteristics of data transceiver, such as
high temperature, humidity, low temperature, strong electromagnetic field or dusty environment.
4. Do not let the data transceiver continuously be in full-load transmission state, otherwise the transmitter may be
burned out.
5. The ground wire of the data transceiver should be well connected with that of the external equipment (such as PC,
PLC, etc.) and of the power supply. Otherwise, it is easy to burn the communication interface; do not plug or
unplug the serial port when electrified.
6. When testing the data transceiver, it must be connected with a matching antenna or a 50Ω dummy load,
otherwise it will easily damage the transmitter; if the antenna is connected, the distance of the human body from the
antenna should preferably exceed 2 meters to avoid injury and cut. Do not touch the antenna while launching.
7. Wireless modem often have different communication distances in different environments. 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 50. Communication distance
margin above %.
8. If the measured communication distance is not ideal, it is recommended to check the antenna quality and the
