There should be no interference of the Reader from other electrical devices in the environment.
The Noise Level difference should be less than 20 mV.
-
The ID ISC.LRM2500 reader should be set to an RF power of 8 watts.
-
When using ISO 15693 transponders, the Readers should be set as described in
-
If multiple gates are operated at the same time at a distance of less than 8 m, the Readers
must by synchronized. See Application Note

Table 5: Gate distance
Supplementary equipment (e.g. light barrier, lighting, etc.), mounted directly on the antenna or in
the immediate vicinity of the antenna can interference with the functioning of the system.
A minimum distance of 20 cm is required.
Electrical cable, directly at the antenna or in the immediate vicinity of the antenna, can be cause
interference. A minimum distance of 20 cm is required.
A minimum distance of 65cm between the two gate antennas is required.
