R13-112B8-02-BBR is a SCI part mountable computer interface board. It contains 68-pin female D-Sub connector and active pull-up/down termination for multi-drop lines. It is used for applications requiring multiple channels of digital I/O from a single card. It supports 8 lines of 24-bit bi-directional data communication at up to 16MHz. It uses a UART-based protocol and has both RS232 and EIA-485 serial communication busses. It also has an internal voltage supervisor that allows power monitoring and resetting of the board.
