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 resourc-
es 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 automa-
tially set as input ports during system startup a reset, with a default
signal level of logic 1(high). (But see Jumper JP1 discussion below.)
