3  Installation

Installing the hfMux-X is an easy task for experienced electrical personnel. Some important
notes should be considered as listed at the end of the installation instructions.

Step 1:

Place the multiplexer in the desired installation location and attach it there if necessary. The

device does not have a preferential mounting orientation.

Step 2:

Both   the   reader   connection   and   the   antenna   connections   are   connected   via   BNC
connectors. No special tools are necessary for this step.

Step 3:

Connect the control lines between reader (or any other device that controls the multiplexer)

and the multiplexer. The device has optically isolated 24 V inputs which are used by many
industrial devices, e.g. PLCs. Each input needs a 24 V line (e.g. hfMux-4: Inputs IN1+ and

IN2+) as well as a ground line (IN1- and IN2- for hfMux-4) for the differential signal. If your
devices doesn't have single GND lines, you can connect all of them to the ground of the

controlling device.

If you use a metraTec RFID Reader to control the multiplexer, just connect the multiplexer

control cable you should have received with the multiplexer.

Step 4:

Connect the multiplexer with a 24 V power source. This can come directly from the reader if
it supports this (Pins 24V and GND).
