The ROS-MD-D02B 2-Reader expansion board is designed with a focus on high quality and reliability and is ideal for residential and commercial applications. Easy to install and operate, the MD-D02B expansion board features supervised communications with the controller. The expansion board adds two additional readers or keypad inputs, four relay outputs, and four supervised inputs to the access control panel. As a result, an access control panel with the MD-D02B expansion board can support a total of four readers and four doors. In addition, it is possible to add any keypad or biometric reader that supports
Wiegand, Clock-and-Data or any other format supported by Rosslare's AxTraxNG software transmission formats. The host access controller has complete control over the additional readers, inputs, and outputs of the MD-D02B expansion board.
