adjustments by the user.
The CRS-305, CRS-306, and CRS-307 RMI cards come pre-configured for proper operation. All
three cards share a common printed circuit board (CEFD P/N PC/11494x); what distinguishes the
cards from one another is the configuration of front panel connectors, and configuration of the
JMP1 jumper setting on the PCB.
Figure 5-3 shows the PCB used for all three RMIs, with the typical JMP1 jumper location
identified.
