    The RJ45 interface is used for connecting an encoder to the device with the relevant configuration of the 3TK2810-1. With the appropriate transfer cable (see accessories), the interface can also be used to parameterize another device using the copy function. This is important if the speed monitor is to be used in a standard application, or if it has to be replaced in the event of a fault.
