3.5.3 Common electromagnetic interference causes and solutions
The following provides a reference to some common electromagnetic
interference solutions：
 The switching power supply interferes from the current conduction to the
device. It can be solved by replacing the independent power supply or adding
a filter at the power supply.
 Cable couple Electromagnetic interference in the space. Insufficient cable
shielding or the reader is not well grounded, which can be solved by
improving the shielding performance of the cable and making the reader well
grounded.
 Antenna interference between readers. It can be solved by increasing the
safety spacing of adjacent readers and reducing the transmit power of the
reader.
 Control cabinet or chassis interference. The electrical planning of the control
cabinet or the casing is unreasonable, the grounding is missing or bad, and
the“0”potential imbalance causes interference,which can be solved by
rationally designing the control cabinet or the casing.

4.1 The product features of reader
The SG-UR-I84/I85/I86 series readers are compatible with multi-protocol (EPC Global
Class I Gen2/ISO 18000-6C) and support RS485, RS232, TCP (POE), bluetooth and
other (configurable) communication methods. It is convenient for large-scale batch
networking applications and provides isolated I/O to detect external sensing input and
output control signals.
It has the following advantages:
 Support anti-collision algorithm: Bulk tag identification speed is greater than 400
/ s, a high recognition accuracy;
 Support for Received Signal Strength Detection (RSSI);
 Supports four-channel polling: It can be used for multi-node data acquisition to
improve the coverage area of device data acquisition; or single-node multi-
antenna deployment to improve the reliability of label recognition within the
coverage;
 Different antennas can be connected via feeders: with appropriate labels to satisfy
different identification distance requirements;
 Die-cast aluminum alloy casing: good heat dissipation.。
