10.1. [0x9F] Piggyback Command for Peripheral Devices
This protocol embeds any command for peripheral devices, connected at a communication port of
a Reader. The Reader unpacks the internal command and sends it over the specified communica-
tion port. The commands described in the following chapters must all be embedded with this Pig-
gyback Command.
If the communication with the peripheral device fails, the command returns with status 0x20.
