Figure 9 shows the connections of the serial link to the first Intelligent Detector Backplane.
The sequence of connection set out in Table 2 should be followed. The GSPI serial link is
connected from the first Intelligent Detector Backplane OUT socket into the second
Intelligent Detector Backplane IN socket. This sequence of connections should be followed
for connection between first Intelligent Detector Backplanes and the final Intelligent Detector
Backplane. Please also note that a separate infrared connection is required for SLD4
automatic set-up. This link operates horizontally and therefore SLD4 cards must be mounted
alongside each other to communicate in this fashion. Please refer to Figure 9 which shows
the required connection to continue this infrared link vertically.
