ULTRA-485 Manual
Chapter 2: Card Setup
The ULTRA-485 contains several jumper straps that must be set for proper operation.
Address Selection
The ULTRA-485
occupies 8 consecutive I/O locations and looks to the PC as a standard serial
port. A DIP-switch (SW1) is used to set the port address options for the ULTRA-485 . Be careful
when selecting the port addresses as some selections may conflict with existing ports. The following
table shows the addressing options available with the standard PAL. If different address options are
required, contact Technical Support about a custom PAL option.
