3.1 Overview
Maintaining signal connections is one of the most important factors in ensuring that
your application system is sending and receiving data correctly. A good signal con-
nection can avoid unnecessary and costly damage to your PC and other hardware
devices. This chapter provides useful information about how to connect input and
output signals to the PCIE-1751 via the I/O connector.

3.2.1 Jumper JP1 Restores Ports to Their Condition Prior to Reset
Jumper JP1 gives the PCIE-1751 a new and valuable capability. With JP1 enabled,
the PCIE-1751 “memorizes” all port I/O settings and output values, and, in the event
of a “hot” reset, the settings and output values present at the port just prior to reset
are restored to each port following the reset. This feature applies to both ports set by
software, and to ports configured as output ports via jumpers. Depending on the
application, this capability may allow a card to be reset without requiring a complete
shut- down of processes controlled by the card (since port values are left unchanged
and are interrupted only momentarily). Complete loss of power to the chip clears the
chip memory. Thus, even if JP1 is enabled, if the power to the card is disconnected,
the card’s initial power-on state will be the default state (for software-set ports) or the
state of an output port with low voltage output (for jumper-set ports). When jumper
JP1 is not enabled, power-off or reset results in ports returning to their default state
(for software-set ports) or returning to the state of the output port with low voltage out-
put (for jumper-set ports).
