You should pay more attention to some matters when using the dongle. Only adequate prevention can make the use work more smooth. Here are eight matters needing attention from Zhejiang University's central control dongle.
1. Pay attention to waterproof and moisture-proof when using the dongle. When not in use, the cover can be installed, mainly to prevent moisture and dirt.
2. The computer shall be well grounded. If the grounding is poor, the dongle may be damaged in case of leakage, because the normal working voltage of the dongle is 4.5-5.5V. If the working voltage is exceeded, the dongle may be damaged
3. Try to use qualified power supply. The power supply part is easy to be ignored, but due to good power filter, it is an important part with good performance, no leakage and surge current, stable voltage, not too high or too low.
4. If there are many peripheral devices in the computer, poor power supply may easily lead to low voltage, which may cause the dongle to become unstable and increase power supply.
5. If it is inserted into the front USB of the computer, be sure to pay attention, because some computers will be connected to the front USB cathode in reverse, which will directly burn the dongle. At the same time, the connection quality of some front-end USB is too poor, which is easy to cause stability and surge failure
6. Try to use qualified motherboards. The motherboard is a bit messy, and the USB interface quality is poor, which is easy to cause the dongle or lead unstable inrush current to damage the dongle.
7. Try not to insert the dongle into the cooling position of the power fan, because the working temperature of the dongle is 0-70 degrees. If the heat dissipation is poor, the dongle is easy to burn.
8. If an extension cord is used, please try to use an extension cord with a shielding layer, because some extension cords have poor quality, which may lead to unstable signals and voltages. If the quality of some extension cords is poor, it is easy to cause inrush when dialing out and inserting, which will damage the dongle.
The eight points for attention when using the dongle have been explained. I hope we can help you. More information can be found on our website http://www.hotelfidalgo-goa.com Consult!
