1. Communication between Reader and Function Unit
The function unit has an interface for communication with the reader. The communication takes
place trough the cable connection between the reader and the function unit. The function unit can
be controlled by means of the protocols described further below. Control of the function unit is pos-
sible either directly by the reader or by the application using commands from the host to the
reader.
Since communication and control of the function unit is accomplished using the antenna connec-
tion on the reader, no additional connection between reader and function unit or host and function
unit is required.
Figure 1 shows a system consisting of a host, e.g. a PC, the reader and the function unit:
Figure 1: System with one Function Unit
It is possible to connect multiple function units an a cascading arrangement. (see Figure 2).

In one example (see. Figure 3) there is a system with three function units. One function unit is a
multiplexer (MUX1). Two other function units, two antenna tuner (DAT2), are connected to the mul-
tiplexer.

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 2.1.4. Multiplexer Address
Setting.
Below are several examples which demonstrate the possibilities for a multiplexer.

2.1.1. Configuration using one Input
Figure 6 shows a configuration with one multiplexer and three antennas.
Figure 6: Multiplexer with three Antennas
The individual antennas can be switched by the reader over the HF line using protocols. Only one
output can be active at a time.
The protocols always contain the address of the multiplexer to be activated. This means that even
when using only one multiplexer, it must be addressed also (see 2.1.4. Multiplexer Address
Setting).

2.1.2. Configuration using both Inputs
Figure 7 shows a configuration with two gates consisting of base antenna (B) and complementary
antenna (C).
Figure 7: Multiplexer with two Antenna Gates
The base antennas are connected to input IN1, and the complementary antennas to IN2. The
reverse is not possible, since protocols from the reader can only be received on IN1.
The corresponding gate outputs (e.g., output OUT1 on base antenna Gate 1 and output OUT2
complementary antenna Gate 1) are switched simultaneously. Only one gate can be active at a
time.
The protocols always contain the address of the multiplexer to be activated. This means that even
when using only one multiplexer, it must be addressed also (see 2.1.4. Multiplexer Address
Setting).

2.1.3. Configuration with cascaded Multiplexers
Figure 8 shows a configuration with cascaded multiplexers.
Figure 8: Configuration with cascaded Multiplexers
In this configuration multiplexers are cascaded one behind the other. Since each multiplexer can
have only one active output at a time, it is only possible to activate the multiplexers on the switched
branches. It is not possible to activate all multiplexers at the same time.
The protocols always contain the address of the multiplexer to be activated (see 2.1.4. Multiplexer
Address Setting).
