HYB POTT RX1 through HYB POTT RX4:
These settings allow the user to select the FlexLogic operands that repre-
sent the receive signals for the scheme. Typically input contacts interfacing with a signaling system are used. In single-
bit applications,
HYB POTT RX1
must be used. In two-bit applications,
HYB POTT RX1
and
HYB POTT RX2
must be used. In
four-bit applications,
HYB POTT RX1
,
HYB POTT RX2
,
HYB POTT RX3
, and
HYB POTT RX4
must be used.
