Master/slave is a model for communication protocol in which one device (master) controls one or more other devices or processes (known as slaves). Once the master/slave relationship is established, the direction of control is always from the master to the slave(s). Another terms that could be used to refer to the same model is primary/secondary.
In this model, only master stores memory and the slaves do as the master says or instructed.

R2i shall be connected to R2 that has eleven pins in the rear and i-Kadex shall be connected to Kadex reader.
The availability of the slave readers saves cost significantly, as the slaves can act as OUT reader at a much reduced price. Complete fingerprint system or card system is achievable through master/slave model.
