5-3-13 Relay Board (RLY)
5-3-13-1 General Description
The Relay Board hosts the connectors for the probes.
• On systems without 4D (RT3D), the Relay Board has three PA probe connectors plus a “blind” PA
slot used to park a fourth probe.
• On systems with 4D (RT3D), the Relay Board has four probe connectors. The three leftmost
connectors are used for PA probes, the fourth connector is used for the 4D probe.
The Doppler (Pedof) connector, on the front of the Vivid 7, is connected to the Relay board via an
internal cable.
• In receiving mode, the Relay Board connects the transducer channels from the selected probe to
the RX and TX boards via the XDBUS.
• The Relay Board routes the TX power supplies to the active probe.
• It also routes the Probe Multiplexer Control Signal to the active probe.
• FEP2 ONLY: The connectors for the XDBUS connection, are color coded to match the colors on
the connectors on the XD BUS Board, to reduce the risk of using the wrong type of XD Bus boards.
