Principle of operation

You can operate up to six antennas on one reader by using the multiplexer RF260X. The
data is processed sequentially.
Antenna switchover is performed in time-multiplex mode, so by connecting several antennas
together, the processing time / activation time per antenna is lengthened accordingly.

If a longer antenna cable is required between the RF290R and SIMATIC RF260X
multiplexer, a 7.2 m long cable (e.g. 6GT2691-0DH72) must be used to extend it, see
Ordering data (Page 241).
The excess length must then be rolled up bifilar and fastened to minimize interference
from external sources.
