PTM 535Z – 2.4 GHZ PUSHBUTTON TRANSMITTER MODULE
2.6
Hardware configuration interface
PTM 535Z provides a hardware configuration interface based on six zero Ohm resistor foot-
prints (R1 … R6).
Populating these resistors allows customer-specific adaption of the following parameters:
Hardware-based security mode selection
Hardware-based radio channel selection
2.6.1
Hardware-based security mode selection
By default, PTM 535Z transmits securely authenticated data telegrams based on AES128
encryption standard using a 16 byte device-unique secret key and a 4 byte sequence
counter.
For certain applications it might be desirable to transmit data telegrams without sequence
counter and device security key / telegram signature. PTM 535Z can be configured to do so
by populating configuration resistor R2.
