2.5 Safety during installation
In order to ensure your personal safety and the safety of your belongings, please
make the following preparations before the installation of XC-RF850 reader.
Check if the ground terminal of power outlet has been connected to the
ground, and check if the local power supply voltage is compatible with
the reader’s voltage range!
Ensure the grounding of the equipment metal casing. Use Invengo
“grounding wire Φ 4.2 (double) _18AWG_ green yellow_1.5m” cable.
The internal material code of the grounding cable is 2200500034.
Measure and estimate the distance between the equipment and the
system (for example reader and antenna, reader and PC, reader and
power outlet);
Check if the location and direction of reader and antenna will generate
signal interference to the information exchange between the reader and
the electronic tag;
Take note of the choice and length limitation of the serial cable;
Install and use the reader after only status testing;
During the installation of multiple readers or a high concentration of
readers, take note of the antenna positioning and minimum distance
between each antenna to avoid mutual interference
2.5.1 External RF cable
RF cable requirement:
RP-TNC (male) connects to the connection port in the reader, while the N-JAY
(male) connects to the connection port in the antenna. The recommended RF
cable is RF cable RP.
TNC-4(male)_KSR240_N-J4Y(male)_6m, input impedance 50Ω and line losses
of less than 2dB.
The internal material code for the RF cable is 2200800009.
Excessively long RD cable will lead to attenuation of RF transmitting
signal and receiving signal, resulting in deterioration of read and write
performance.
