The ROUTE 56 contains several jumper straps for each port, which must be set
for proper operation.
Address Selection
The ROUTE 56 adapter occupies a total of eight consecutive I/O locations. A
DIP-switch 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.

Figure 1 - Address Selection Table
The following illustration shows the correlation between the DIP-switch
setting and the address bits used to determine the base address. Assume 300
Hex to 307 Hex is the desired base address. 300 Hex = (1) 1 0000 0X in
Binary.

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