TMC2070P7C
Parallel to RBUS Adapter
Features
• Parallel Input
• RBUS Output
• Fairchild demo board compatibility
Applications
• Evaluation of Fairchild demo boards
• System Breadboarding
Description
The TMC2070P7C RBUS adapter provides a simple interface between a computer parallel port and RBUS. It can be
used with standard I2C drivers or the Fairchild Raydemo
software.
Preliminary Information
This adapter requires a bi-directional parallel port. Power is
supplied through the connectors. Be careful when using a
parallel cable with this product. Some cables flip pins
between the input and output connectors which may cause
undesirable results.
