The SCALA readers are write / read units that can be used in combination with the SCALA access control system. They are used for non-contact identification in SCALA. The reader can be used both in the interior and in the outside. The display is visually via LEDs as well as acoustically. Thus the user immediately recognizes whether the access is granted or new user rights are written on the ID. The data of the transponder is converted 1: 1 analog / digital and sent to the SCALA controller. The security of the encryption is identical to the security of the air interface between the user card and the reader. - 124; All security-relevant processes are not carried out in the reader, but are controlled in the controller. For example, a manipulation between the means of identification, the reader and the controller is excluded according to the current state of the art - such as listening to the encryption or exchange of the reader by a compromised unit. The SCALA readers have standard integrated temperature and voltage sensors that continuously measure the temperature and input voltage of the readers. This can prevent preventive interference. The SCALA readers have standard integrated temperature and voltage sensors that continuously measure the temperature and input voltage of the readers. This can prevent preventive interference. The adjustable operating conditions are displayed via a yellow, a two-color (red / green) and a RGB LED. The transmission quality between the user card and the reader is displayed via the RS485 bus using a communication LED. The communication between SCALA reader and controller is made via an RS485 interface. The communication as well as the power supply takes place via the 4-wire line.
