Low Frequency Demo Reader - RI-ACC-ADR2-10 - Communication fails

David Biehler
Prodigy 30 points


Hey guys,

 

I've got a huge problem with such an ADR2. I need to use that board with LabView, its a programming language from NI.

My connectivity is made up with RS232. So when I use the RFID-Demo Software especially for the ADR2 it mostly works fine. I don't know what kind of COM-Settings are made but it works.

When I try to use the ADR2 with my LabView programm sometimes its working sometimes not. Mostly right after using the RFID-Demo it works also within my programm. But thats not a solution and its not even working always.

When I try to get the device ID from a assembly, I send him: 010884021410F002000A72

Mostly I recieve: 010B0000000000... but also some fragments from the write part...

Thats the code I expect to recieve: 010B007E1AF81C07B0F30204A168

 

Does anybody know the complete Serial Configuration Settings of this ADR2 ?

    here are your basic PaLFI commands listed with responses (from my notes, several years back)

    4300.PaLFI Commands.doc

    COM port settings should be 9600, 8N1...

    I almost forgot to show up with the solution....

    My only problem was that I forgot to send 3 specific commands to the board before I want to communicate with any other commands.

    1. (is optional) Get SerialNumber

    TX: 01010504

    RX: 010505020804010F

    2. (needed) I guess its a activation code

    TX: 010D170154009600A0009600FA009683

    RX: 010D190154009600A0009600FA00968D

    3. (needed) same as 2

    TX: 010B1B01AE009604B000AA100126

    RX: 010B1D01AE009604B000AA100120

    After using the command 2 and 3 i was able to use the board like I wanted in the begining.

    But another problem occured. When the board is getting unpowered and repowered it sometimes just want answer those three commands to start a working session. Even with the RFID Demo Software from TI it isn't possible... only after a few on offs off the power it will react the way it should do. Is there any known issue like that, and even a solution?

    peace Dave
