2.1 Installing and Connecting the RFID DAS 9200 Reader
The primary installation and connection steps for the RFID DAS 9200 system are:
1. Position the Reader appropriately and mount the Reader in a stable location
Choose an appropriate location for the Reader. You should always keep the unit away
from extreme temperatures and sources of electromagnetic interference as this may
degrade performance and lifetime of the Reader.
It should be noted that heat is generated when the Reader is actively running and care
should be taken to ensure appropriate ventilation. Other instruments or items should
not be placed on top of the Reader.
2. Connect the antennas to the RF ports on the Reader
Each RF port should be connected to a recommended RFID antenna or ceiling tile port.
Where a port is left used for any reason it must be terminated with a 50 ohms load
(both on the antenna and reader).
Warning: The Reader will be seriously damaged if any of the ports are not connected
to an antenna or terminated with a 50 ohm load before operating it.
The following steps need to be taken in order to install the antennas reliably:
1) Select the antenna locations. The recommended antenna arrangement is shown in
figure 4 (for Space Ranger applications, other potential antenna configurations are
detailed in the Installation Guide). The antennas should also be positioned:
Away from metallic objects which fall in their field of view,
Away from sources of interference (such as compact florescent lights)
With a separation between antennas greater than 0.25m
Away from locations where persons are likely be within 0.25m of the radiating face of
the antenna for periods exceeding 6 minutes.
2) The antennas should be securely mounted in accordance with the instructions
supplied with the antenna.
3) Attach the antenna cables to the antenna ports on the Reader as detailed in the
installation diagram. The cable connectors should be a tight as can comfortably
achieved by hand, but under no circumstances should tools be used to tighten. A note
should be made of the cable type and length connected to each antenna port.
