2. Antenna Multiplexer ID ISC.ANT.MUX
2.1. System Description of the Multiplexer
The ID ISC.ANT.MUX multiplexer can communicate with a reader. This means that no additional
cabling beyond the HF connection (coaxial cable) is needed to control the multiplexer.
The multiplexer has two inputs (IN1 and IN2) and eight outputs (OUT1-8) (see Figure 4).
Communication, i.e., control of the multiplexer takes place exclusively on input IN1.
Figure 4: Multiplexer
Each output can be assigned to one of the two inputs. Only one output can be active per input. The
procedure for assigning the outputs is described in the installation guide for the ID ISC.ANT.MUX
multiplexer (M30201-xde-ID-B). Figure 5 shows two common configurations.
Figure 5: Configuration Examples for Assigning Outputs on IN1 and IN2
Additional multiplexers can be connected to the outputs of any multiplexer to increase the number
of channels. Here the multiplexers must be addressed for controlling the respective units.
Addressing of the multiplexers is described in greater detail in section
Below are several examples which demonstrate the possibilities for a multiplexer.
