External Interface Breakout Board
The External Interface Breakout Board is an accessory that allows convenient
access to several potentially useful TTL output and input signals. It also offers a
simple way to connect logic analyzers or other tools to the Analyzer unit.
The Breakout Board connects, via a ribbon cable, to the Data In/Out connector on
the rear of the Analyzer box. Four ground pins and one 5-volt pin are provided.
Each pin is isolated by a 100
Ω
series resistor and a 74F244 inside the Analyzer
box.
