Tamper alarm using G2iM

[Twsnhbb]

Hello, 

We are attempting to use the tamper alarm feature with the G2iM+ IC. We are able to read and write the EPC on the tags as well as read the TID banks to identify the chips. However, when we attempt to access the alarm at either 0x200 or 0x20F we receive a PC OVERRUN error message and an exception is thrown. 

We are using a thingmagic M5e reader. Can anyone offer advice or support? We are also having the same issue accessing the memory address with our TSL 2128P reader. 

Thank you

Hi @Twsnhbb ,

first of all you have to make sure that you have a G2iM+ not a G2iM, the non plus version does not have the tamper alarm feature,  second, can you confirm that  you have checked the following appnote section 16.
