Table 2: Pin assignment of the Configuration Plug

3.2.2.1 Pin programming scheme

The programming pins Con_Sel_0 (LSB) to Con_Sel_4 (MSB) are used to represent the configuration

index, whereas Con_Sel_5 is used as the parity bit (even parity). See also Figure 6b on the previous page

and Table 2 on this page. Depending on the selected programming pin combination, a switch configuration

is loaded from one of 16 possible positions.

• If the dip switch is set to position ON, the pin is connected to Ground on the connector.

• If the dip switch is set to position OFF, the pin is not connected at all on the connector.

Table 3 on the current page lists the valid programming pin combinations that are possible for the default

configuration (Con_Sel_0 = OFF).

NOTE

To select a programming pin combination for the actual/backup configuration, set Con_Sel_0 to ON.
