DIO-104.REL User Manual
Card Setup
Address Selection
The DIO-104.REL contains several jumper straps for each port that must be set for
proper operation.
The DIO-104.REL occupies 4 consecutive I/O locations. The DIP-switch (S1) 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 several examples that usually do not cause a conflict. To maintain
compatibility with other Sealevel Systems I/O adapters, the actual port addresses are
found at BaseAddress+2 (Relays K1-K8) and BaseAddress+3 (Relays K9-K16).

The following illustration shows the correlation between the DIP-switch setting and
the address bits used to determine the base address. In the example below, address
300 is selected as the base address. Address 300 in binary is XX 11 0000 00XX
where X = a non-selectable address bit.

Note: Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while
leaving it ‘Off’ or ‘Open’ corresponds to a ‘1’.
