DESCRIPTION

The ST20-PPI parallel port to OS-Link interface is

a host interface to allow connection from a PC par-

allel port to any OS-Link based ST20 development

board such as the ST20450-SAB. The interface

plugs into any standard PC 25 way D-type parallel

port. Supported parallel port modes are:

• Nibble mode

• Byte mode

• EPP mode

depending on which mode the host PC can sup-

port. Connection to the development target is via a

differential OS-Link connector, as used on the IMS

B300 and ST20450-Development Board. Once

connected, the development target can be ac-

cessed with the standard ST20 Toolset using the

MS Windows drivers supplied.
