4.6 PDE Rear Connector Units
Rear Connector Units (RCUs) provide a flexible solution to linking the processing and data handling
cards mounted in the matrix to control panels and peripheral equipment.
Note that, in general, RCUs are loaded into slots corresponding to their 'front-loading' companion board;
actual positions are dictated by the system 'map'.
RCUs are 9U high and 150mm deep. Connection is made to the backplane via 96-way DIN connectors.
4.6.1 PDE 4622TX - 16 Channel CODEC RCU
Figure 77 - PDE4622RX 16 Channel CODEC RCU
This RCU performs the same function as the 3622 RCU, transformers being used to balance the audio
inputs and outputs.
