Receive Interface with 1:1 and 1+1 Redundancy
The receivers on the backup card should be programmed for "High" impedance. Since there is no external
resistor in the circuit, the receivers on the backup card will not load down the line interface. This key design
feature eliminates the need for relays and provides one bill of materials for all interface modes of operation.
Select the impedance for the desired mode of operation. To swap the primary card, set the backup card to
internal impedance, then the primary card to "High" impedance. See Figure 24. for a simplified block diagram
of the receive section for a 1:1 redundancy scheme.
