Hi,
we're also lost at the same step as Kevin.
We have swithed from SL0 to SL1. However now we are unable to perform the first authentication in order to switch from SL1 to SL3 since we are unable to set "Layer 4 communication". We are using the ACR1222L from ACS. Can anyone give a hint on how to active Layer 4? We have some cards which already are in SL3 and we can correctly authenticate, write and read encrypted without a problem.
Thank you in advance
