2.9 External Interface Breakout Board

The External Interface Breakout Board is an accessory that allows standard,

LV TTL signals to be channeled into the analyzer for triggering or out of the

analyzer for use by an oscilloscope, logic analyzer or other device. Six

ground pins and one 5-volt pin are provided.

Drive strength for all outputs is about 30mA high (@2V) and 60 mA low

(@0.5V). Inputs can handle 0 to 5.5V. Inputs above 2V are detected as logic

high; inputs below 0.8V are detected as logic low.

The Breakout Board connects via a cable to the Data In/Out connector

located on the rear of the analyzer unit. Each signaling pin is isolated by a

100Ω series resistor and a buffer inside the Analyzer unit.

Pin-Outs for the Data In/Out Connector

The following table lists the pin-out and signal descriptions for the Data

In/Out connector on a cable that connects to the Breakout board.
