2). Please ensure that the power supply of the reader device is normal. If the
reader device does not have a rated power supply, the DEMO cannot be connected to
the device.
3) The COM port selection is incorrect. If you connect the device to the PC,
please check the COM port number used by the reader device in the PC device
manager, and make sure it is consistent with the COM number you selected in DEMO.
If the reader device is not connected to the PC, please use other methods to determine
whether the selected COM port is correct.
4). The network port connection must select the IP address connection, and the
serial port must select the COM connection.
5) Whether the wiring is correct: Please ensure that the wiring connected to the
reader device is correct. The standard cable wiring method is: brown +, blue -, white
A, black B.
8.4 Processing method of unstable read distance
1). Use an independent power supply as much as possible for the power supply
to ensure that the remaining 30% of the power margin is at the highest power
efficiency and the smallest ripple. Use at least 0.38mm^2 for the power cord, and add
a filter if necessary.
2). The power supply voltage input range is determined to be within 24V+-20%,
and it can be used if it exceeds the range, but the stability is relatively poor;
3). The length of the feeder is too long and seriously bent, resulting in too much
loss.
4). The antenna connector is loose.
5). The reader should avoid irregular large areas of metal around it, and keep it
away from the frequency converter and inverter.
6). Avoid turning on two readers at the same time.
7). The radiating surface of the tag antenna is facing the front of the reader, and
the reading distance is the farthest.
8). The actual use distance cannot exceed 50% of the estimated distance.
8.5 The long-term working reliability of the reader decreases
The product has a watchdog function inside, which effectively prevents crashes.
The products use high-reliability parts, including industrial grade and automotive
grade.
Die-cast metal shell can effectively passively dissipate heat.
When the ambient temperature is >55℃, active cooling equipment must be used.
Or reduce the card reading power and reduce the number of card readings.
