REL-32 User Manual

Card Setup

The REL-32 contains several jumper straps for each port that must be set for proper
operation.

Address Selection

The REL-32 occupies 4 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
several examples that usually do not cause a conflict.

Address Selection Table

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 XXX 100000 XXX
where X = a non-selectable address bit and address bit A9 is always a 1.

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