2.3 Jumper Settings
We designed the PCI-1753/1753E with ease-of-use in mind. It is a "plug
and play" card, i.e. the system BIOS assigns the system resources such as
base address and interrupt automatically. There are only two functions
with 17 jumpers on the PCI-1753, and one function with 16 jumpers on
the PCI-1753E. The following section describes how to configure the
card. You may want to refer to the figure below for help in identifying
card components.

Jumper Settings to Set Ports as Input or Output by Software
When the two pins of jumpers JPA0, JPB0, JPC0L, JPC0H, JPA1, JPB1,
JPC1L, JPC1H, JPA2, JPB2, JPC2L, JPC2H, JPA3, JPB3, JPC3L or
JPC3H are not shorted (i.e., by setting a jumper), the corresponding ports
are set to be configurable as input or output ports by software. (JPA0
means jumper for port A0, JPB0 means jumper for port B0, etc. See
Table 2-1) If jumper JP1 is not enabled (i.e., by shorting the upper two
pins of JP1), all ports configured by software are automatially set as
input ports during system startup a reset, with a default signal level of
logic 1(high). (But see Jumper JP1 discussion below.)
