With the SALTO Control Unit Adaptor, it's possible to integrate with third party devices such as time and attendance systems. The Control Unit Adaptor is designed to allow users to update their cards at the reading point that they use on a daily basis, for instance a Time and Attendance terminal. This means you can now access a door with all the convenience of SALTO and control your staff attendance at the same time. The CU Adaptor is connected on one side to any SALTO door controller, and on the other side to the external device. The interface with the external device can be RS232, OMRON and WIEGAND.
