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
