3.4.2 Internal/External antenna: Terminal X2, Jumpers J2 and J3

Terminal X2 is used to connect an external 50Ω antenna to the ID ISC.M02. This is a standard pin
connector with 2.54 mm spacing. Table 8 shows the pin assignments for Terminal X2.
Pin no.
Jumpers J2 and J3 connect the internal antenna to the driver circuit of the reader. To connect an
external antenna, both jumpers J2 and J3 must therefore be removed.

NOTE:
• If both jumpers J2 and J3 are not removed after connecting an external antenna, the
reader's transmitter will be loaded by both antennas. This could result in permanent
damage to the transmitter!
