Overview
The DSS-8224 is a dual serial switch designed for broadcast use in a multi-definition broadcast environment. This
card supports both standard definition 270Mbps and high definition 1.485Gbps SDI video, as well as other common
serial digital signals at 143Mbps, 360Mbps, and 540Mbps.
Each DSS-8224 has four inputs and two outputs. Each output is available on two BNCs. The DSS-8224 can be
configured for 7x1, 4x2, 4x1, Dual 2x1, or 2x1 operation.
Each switch is controlled by an optional control module (RMC-8120 or RMC-8120-1), by GPI contact, or by logic
level. All switching is done in the vertical interval, and timed to an external analog reference. The DSS-8224 can
use either of the two frame references that are distributed to all cards in the openGear frame. The appropriate
switching line is automatically determined by the reference frame rate (50Hz or 59.94Hz), and the SDI data rate.
The last input selected for each output is stored in non-volatile memory for power failure protection.
The DSS-8224 equalizes the incoming SDI signal, which compensates for up to 300m of cable at 270Mbps, and
over 120m of cable at 1.485Gbps. The serial data rate is determined automatically, and the signal is optionally
reclocked on output.
LEDs are provided to indicate input and reference signal presence, and to show which input source is selected for
each output.
The DSS-8224 is fully compliant with all openGear technical specifications and supports remote monitoring via
DashBoard Control System software.
