ST20-PPI Datasheet - STMicroelectronics

DESCRIPTION
The ST20-PPI parallel port to OS-Link interface is a host interface to allow connection from a PC parallel 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 support. 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 accessed with the standard ST20 Toolset using the MS Windows drivers supplied.
