Hi, You are dealing with physical laws ! We cannot really change the physics, but there are a few tricks to improve the situation. At the reader side, you have to be careful with all the conductive materials (hands of the operator, metallic parts, water content parts). The UHF antenna should be away...

Hello Chupakabr, Could you tell us which antenna you are using (endcap or backplate)? Also, what kind of tags are you using (chip or tag manufacturer) and what they're attached to? In the meantime, if you had previously used the A828 reader and swapped it with the A528 reader without clean...

Hi all. I have a problem with rfid reader range. I develop an application for WORKABOUT PRO G2(7527) on Windows CE 5.0. It has installed CAEN RFID reader. As software development kit I use "com.caen.RFIDLibrary" and "PsionTeklogix.RFID" library. I have installed "RFIDDriver_WAP_UHF_CA1_A1_G2"...

I need a catalog the WAPRO3 with RFID CAEN UHF (circular antenna). I appreciate the help.

Fabien or Pierre will get back to you on the scanner option.

Hi Andreas, The bar code scanner cannot be mounted properly, because of mechanical inteference between the top of the UHF CAEN connector and the electronic board of the end cap scanner. As a consequence, this option is not authorized (too risky with drop tests and mounting). On an other hand, the option...

Did you test the CAEN Demo to validate the connection and functionalities before to start CAEN Wedge? Please note Demo and Wedge can't work at the same time. Which Operating System are you working on? (WinCE / WM)? Thanks

Sorry for the multiple tests. I don't succeed to reproduce the problem. However, if the problem occurs on the operating system loading (RFID sets to AutoConnect/ GPRS activated), I suspecte a timing issue, the following driver should correct the problem. (Please visit the site to view this...

An update of RFID SDKs & Demos are available on Downloads section This is not a major update. The commun modifications are: rfid driver to version 1.1 Increase USB detection timeout Update RFIDDriver libraries (C++ & Dotnet) to version 1.3 Add properties for getting Name, Frequency...

Hello Figueiredorj, Assuming that you are working with the 500 mW CAEN UHF module, you should make reference to the CAEN RFID API Reference Manual and the CAEN API User Manual which are part of the SDK. Said document can be accessed at the following link: http://community.psion.com/downloads/developer_sdkhdk...

Hello roddy, The COM port (and the physical interface) used by the XMOD version is different from the GPRS version. The first thing you need to make sure is that you install the appropriate RFID driver for the new reader. You can download the driver manager from the following link: http://community...

Hi Enzo, In addition of the source code editing, for epc, you have to modify the protocol control of the tag. community.psion.com/.../how-can-i-modify-the-epc-length-on-caen-readers.aspx Jan-Ma

The PC value for 16 bytes should be 0x4000 (or 0x3800)

This new article will provide you the guidance for obtaining the rssi (received signal strength indication) from a UHF tag. http://community.psion.com/knowledge/w/knowledgebase/1124.aspx

Hello, What bank memory do you want to write on (EPC, USER, ..)? We provide the sources of CAEN Demo application. They can be modified to support to write on 128 bits. Regards

Hi, The first 2 bytes of EPC defines the length of data to show - this is the Protocol Control field You have 2 solutions One is to use the ProgramID function to modify the EPC - the length of EPC to read will be modified in the same time OR You can modify the Protocol Control at the...

Hola Leonardo! The CAEN A528 reader is not able to handle ISO 18000-6B. If you have a customer who requires this protocol please contact me and we'll discuss this further. Aneline

Hi Marco, Did you use the RFIDDriver library on WAP 3 and NEO? You can take a look on CAEN Tools for more details but the driver is managed like below // Enable RFID Driver RfidDriver.Enable(); // Get ComPort number where RFID reader is connected int comPort = RfidDriver.ComPort; This is...

I've got a CAEN CA3-AC1 reader module plugged into a Workabout Pro 3 which I'm trying to use to write the EPC id of a tag. As I'm developing in C++, I'm using the API from here: http://community.psion.com/downloads/developer_sdkhdk/m/rfid_sdk/23600.aspx The code I'm currently...

Hi, For writing process it is recommended to decrease the power (for example 50mW). So, to reduice physically the distance between reader and tag. Then, you can determinate the best bitrate for your tag, some tags are dedicated to a specific bitrate. http://community.psion.com/knowledge/w/knowledgebase...

I'm allready using the wet inlay on a carton layer, no performance increase. Not even the RFID CAEN Demo v3.31 is working good enough for us.

Hi, I'm using the Workabout Pro 3 with the CAENA528 UHF Module. I have allready used different power levels between 50 - 500 mW. I split the 30 byte EPC to shorter 6 byte arrays and try to write them with the WriteTagData_EPC_C1G2 command, 3 retrys per partial array. After this process...

Hello, I try to test the sample code for RFID with C++ : CaenRfidLib5.zip I have made my first tests on a WAP and it worked. Now on the Neo i'm stuck on "Creatfile[RFID1]: 55" on this : rfidMgrHandle = CreateFile(L"RFD1:", GENERIC_EXECUTE, 0,0, OPEN_EXISTING, 0,0); ...

Hi Benjamin, thank you for reply. the tag non is not placed on metallic or liquid surface. The settings are the same as you have listed. The only Check error that I get from it (set RF regulation: Fail). I'm in europe and from wat I've read it should be normal because I can not change...

Guys I need help you have any idea about this problem?
