The External Interface Breakout Board is an accessory that allows convenient access to
several potentially useful standard, fast TTL output and input signals. It also offers a
simple way to connect logic Analyzers or other tools to the Analyzer unit. Four ground
pins and one 5-volt pin are provided.
