Chapter 1 : Introduction
Problematic :
• The RFID product UHF-CA3-ACX-XMOD doesn’t support any Endcap Scanner options due to a mechanical issue between the RF connector of the RFID and the scanner. That is why both options are not available in the configurator.
Presentation of the product :
• Name : UHF-CA3-ACX-XMOD
• Description :RFID MODULE UHF 500mW Circular polarized Antenna with Xmod connection
• PN concerned : 1100635 (CE) and 1100645 (America)
• Feature : No GPRS and Scanner compliant
Objective :
• Make a specific kitting in order to be compliant with the End-cap scanner options

Chapter 2 : Mechanical Issue
Physical contact between the RF antenna connector and scanner connector.
No possibility to connect the scanner flex
Risk of damage during the drops tests.
Risk to decrease the RFID performance : Noise coupled to the RFID cable
End cap Scanner option not available with this kind of RFID configuration !!!

Chapter 3 : Mechanical Solution
Avoid the mechanical interferences between the connectors
Move the CAEN RFID module a bit higher by placing a shielding plate underneath
Shielding used in the GPRS option : PN 1050659-001 (METALWORK GSM MC75i)
Solution step by step
i. Un-stick the CAEN module from the PCB board
ii. Put an adhesive tape on top of the shielding plate
iii. Position the shielding between the PCB board and the shielding plate
iv. Stick and Place the RFID module above the shielding plate
v. Put new EMI gaskets on the RFID module (thicker ones)

Chapter 3 : Mechanical Solution
Follow the same routing cable for the scanner flex
No longer mechanical interferences
This solution is valid only for the 1D Laser and Imager scanners
Endcap scanner compliant with this solution : 1D EV15 Imager / 1D Laser SE955

Chapter 4 : Specific Case 2D HHP Scanner
Scanner connector and Flex cable are different from Laser / Imager scanner
If you try to connect UHF Circular Xmod + 2D HHP Endcap, you could succeed in assembling both parts HOWEVER this would lead to some noises issues. Noises coming from the flex would degrade overall RFID performances.
Don’t assembly this way !!!

Chapter 4 : Specific Case 2D HHP Scanner
Follow the same mounting instruction as we previously recommended for Laser and Imager 1D scanner.
Solution :
Solution step by step
i. Use a flex scanner “short version” -> connect the two parts
ii. Put a “Kapton” adhesive tape between both connectors and the PCB
iii. Position the shielding between the PCB board and the shielding plate
iv. Stick and Place the RFID module above the shielding plate
