REL-16 User Manual
Card Setup
The REL-16 contains several jumper straps for each port that must be set for proper
operation.
Address Selection
The REL-16 occupies a total of 2 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 XX 11 0000 00XX
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’.
