The K5DS-BR broadcaster is the main equipment of the DSNet signage system. It broadcasts the audiovisual content and allows the management of the DSNet network. The only difference between the K5DS-BR8 and K5DS-BR16 models is the number of ports.
Monitor emulation. Towards the Player, K5DS-BR acts exactly like a monitor. It provides a full VGA interface, an audio interface and an RS232 interface needed to emulate touch screens. The Plug and Play (DDC) information that K5DS-BR sends to the player can be a record got by capturing the DDC from any monitor of the network. The player "believes" being connected to this monitor.
Audio and video streams. The audio and video streams received from the Player are encoded and transmitted simultaneously on all RJ45 output ports (8 or 16 according to the model) into the UTP cables. The length of cables is limited to 300m.

Management Server. K5DS-BR runs a management server listening to users that try to login to the management port. There is no risk in using the Internet because the connection is secured by SSL.
Management software. DSNet Manager, a Java GUI software provided with the broadcaster, allows anyone with an admission fee to connect to the K5DS-BR management server and to manage all aspects of the network. The software runs on all platforms that can provide a SUN (Oracle) Java 6 virtual machine. It has been tested on Windows, Linux, and Mac Os. In a few mouse clicks you can do audio and video settings of any monitor, enable and disable monitors individually, name network equipments, consult the log, create groups, update the firmware of one or of all equipments connected to the DSNet network, etc.
Bi-directional RS232. The data and the management signals (RTS, CTS, DSR, DTR) coming from the RS232 port connected to the Player are also transmitted in all cables and received by all monitors of the DSNet network. The maximum data rate is 115200 bps. Transmitted data may be commands to control the monitors, or any other types of data. The receivers forward the received data to their RS232 ports, which are typically connected to the monitors. However, it is possible to connect these RS232 ports to other types of devices, such as remote power supplies (see ioPower) to physically turn on and turn off the monitors. One can also imagine using TX/RX RTS/CTS for the monitor and reserving DSR to control an external power supply.
Conversely, all monitors can send data to the Player. They are usually touch screens, but again one can imagine all kinds of different applications such as temperature sensors, motion sensors, etc. The fact that a given monitor uses a bidirectional link or not can be set up.
Note: DSNet does not implement any protocol for the feedback. So there can be collisions as if all monitors were connected to the same cable. The protocol can be nonexistent if collisions are authorized, or it can be implemented between the Player machine and the monitors since DSNet is transparent. On request, PROSUM may implement an internal protocol between the receiver and the broadcaster with some API that must be defined between K5DS-BR and the Player.
Control of equipments. The K5DS-BR broadcaster is in continuous contact with all splitters and receivers of the network. It receives the alarms and sends internal commands as well as commands and controls received from the administrators connected to the management server. It can perform the firmware update of one or of all networking equipments.
Ethernet connection. K5DS K5DS-BR features an Ethernet 10/100 switch and two Ethernet ports allowing connecting it to the same cable as the Player. It thus requires no new connection to the LAN.
Mirroring ports. K5DS-BR features a VGA port, an audio port, and one RS232 port replicating those of the Player and allowing keeping the existing connections. The monitor directly connected to K5DS-BR is in the network. Its DDC information can be captured like the DDC information of monitors connected to receivers. So you can keep the local monitor, the loud speakers and the RS232 attachment previously connected to the Player machine.
Delivery: The K5DS-BR broadcaster is delivered with all accessories (power adapter, VGA and audio cables, rack mount kit).
Warranty and Technical Support: Prosum provides one year warranty and free technical support during the warranty period.
