Figure 2 – Ribbon Cable Routing for the XJLink2 Signals
Each CFM and expander board routes signals between its J10 connector and the MFAB’s multiplexed
signal pins; its J9 connector interfaces to the MFAB’s direct signal pins via relays.
Figure 3 and Figure 4 show a setup using one XJLink2-CFM with three expander boards to utilise all of its
18 signals. Sixteen of the configurable signals are routed to direct signal pins and the remaining 2 are
routed to the multiplexed signal pins of slot 2.
Figure 3 – Recommended Ribbon Cable Routing When Using all 18 Signals
Figure 4 – Distributing the XJLink2 Signals
The connections that the PCB makes between J9/J10 and the MFAB interface on J12 are described in Table 2.
