Part numbers
We want your reader to fit perfectly into your existing system landscape. Do you have any questions on this topic? Our sales team is always ready to provide you with competent support.
The firmware installed during production determines which interface and which required protocol the individual reader uses and thus which system it can be operated on. Therefore, please pay attention to the correct article number when ordering. It is also possible to update the firmware of the reader and thus, among other things, the interface used in the field. This is possible via the RS485 interface of the reader with an associated PC tool after the reader has been set to configuration mode using the RSC security card.
