Keonn AdvanMux-4

AdvanMux-4 is a high performance 4 port multiplexer that expands by a factor 4 the 
number of antennas that can be connected to each port of an RFID reader. AdvanMux-4 is compatible with most RFID reader models in the market, including 
Keonn, Impinj, Zebra, Alien, ThingMagic and others.
AdvanMux-4 is connected to the I/O port of most reader models, and it is controlled 
by sending simple commands to the reader. This facilitates the control of AdvanMux-4 
and its synchronization with the reader. Any port of AdvanMux-4 can be selected at 
any time. 
AdvanMux-4 is directly connected to AdvanReader-60, AdvanReader-70, 
AdvanReader-150 or AdvanReader-160 through a conventional Ethernet cable. 
For other reader models, a reader-specific cable adapter or the AdvanGPIO 
connection board can be ordered that connect the digital I/O port of the reader to one 
of the two RJ45 control ports of AdvanMux-4 multiplexer. The following picture shows 
the cable adapter for a specific reader model and the AdvanGPIO connection board.

The cable adapter can be easily extended to the required length using regular 
Ethernet 8-wire cables. 
Two RJ45 control connectors are available at each AdvanMux-4 so that one 
multiplexer can control and power another multiplexer by a simple Ethernet 8-wire 
cable connection. 

AdvanMux-4 can be controlled both by standard +5 V and open collector digital 
outputs. 
AdvanMux-4 can be powered from +5 V DC to + 48 V DC. This power can be obtained 
from a power supply or by the available voltage in some reader’s I/O ports.  
The input RF connector and the 4 output RF connectors are SMA (female). 
Two red LED diodes show the digital-in status and one white LED shows the power on 
status.
