5.3 RMI Card Configuration Reference
Comtech EF Data provides this RMI Card Configuration Reference for RMI
identification purposes only. Comtech EF Data ships all RMI cards pre-configured –
they require no user adjustments.
Comtech EF Data ships the CRS-305, CRS-306, and CRS-307 RMI cards pre-set for proper
operation. Each card shares 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 Jumper “JMP1” setting on the PCB.
Figure 5-3 identifies the “JMP1” jumper location that typical for all RMI PCBs.

Table 5-1 defines the Jumper “JMP1” settings, as shipped from the factory, for each RMI card.
