Hardware Setup
Address Selection
The SIO-104+16.485 occupies 16 consecutive I/O locations. The DIP-switch (SW1)
is used to set the base address for these locations. Be careful when selecting the base
address as some selections conflict with existing PC ports. The following table
shows the addressing options available. If different address options are required,
please contact Sealevel Systems Technical Support about a custom option.

Note: Setting SW1-1, SW1-2, and SW1-3 all to OFF disables the card, which may be useful
for troubleshooting purposes.
Interrupt Configuration
The board is set up to always share interrupts. There is a jumper labeled “PD” which
is located at (E1) on the SIO-104+16.485. Setting this jumper enables a 1K-ohm
pull-down (biasing) resistor required on one adapter when sharing interrupts. The
jumper should always be enabled on single SIO-104+16.485 installations (non-
shared mode). In multiple SIO-104+16.485 installations, only one board should have
the jumper enabled.
