6.3 3964R communication
This section describes how to use the protocols 3964R and 3964R+RK512 for serial data exchange
between the tightening system and a partner controller.
These protocols can be used to transfer identification codes (see page 200) to the tightening system
and output tightening results from the tightening system.

• ID code transfer to the tightening system via the 3964R protocol (page 266)
• Results output with the 3964R and RK512 protocols (page 269)

Examples for tightening systems with data output via 3964R/RK512
Tightening results output to a partner controller with the 3964R/RK512 protocol is only possible via a
serial interface. The following examples show the structure.
