3.3 Supply Voltage
The supply voltage is connected to X1 or directly to the Reader Connection IN. Configure the po-
larity for X1 as shown in Figure 2. The antenna multiplexer operates with a DC voltage of 12 V to
24 V. In a configuration with cascaded multiplexers you could supply the connected multiplexers
directly over the antenna cable. In this case only the first multiplexer has to be connect to an power
supply unit.
3.4 IN: Reader Connection
The connection to a reader is made using coaxial cable to the SMA jack IN. The maximum
tightening torque of the SMA jack is 0,45 Nm (4.0 lbf in).
The transmitting power at reader connection IN must be at least 85 mW.
