3.2. Antenna connection
Two SMA sockets are provided on the lower circuit board for connecting the basic antenna or, in
the case of ID ISC.LRM200-B, the basic/complementary antenna combination. The maximum
tightening torque for the SMA socket is 0.45 Nm.
Terminal
Description
X1
For connecting the complementary antenna
(only ID ISC.LRM200-B)
X2
For connecting the basic antenna
(Input impedance 50
Ω
)
Notes:
•
The input impedance of the basic antenna should be calibrated to a value of 50
Ω
±
(3
Ω
∠
3°).
•
To achieve optimum read distances the length of the antenna lead-in cables should be
3.6 m
±
0.1 m.
•
When connecting an antenna, ensure that it does not exceed the limit values allowed by
the national regulations for radio emissions.
