Step 5. Other ISA Card Set-up Options
The memory address and interrupt line (IRQ) are software configurable via either your operating system or an installable
driver. You will be asked to specify a 16KB memory window location.
Jumper JP1 on the ISA SYNC/570i-56 controls the Fast Select circuitry on board. The SYNC/570i-56 is shipped with a
jumper connecting pin 2 and pin 3 of JP1. This setting allows the boards to work with any combination of 8 or 16 bit video
and/or network cards supporting Fast Select. When pins 1 and 2 are jumpered, the board must be installed in a 128KB
paragraph which contains only 16 bit cards. The default setting (pins 2 and 3 jumpered) works in most computers and
should not be changed without verification from Digi Technical Support.
