15BTTracer Protocol Analyzer User’s ManualCATC Version 1.0Note The Analyzer is capable of supporting supply voltages between 100-volt and240-volt, 50 Hz or 60 Hz, thus supporting all known supply voltages around theworld.Step 2 Use the power switch located on the rear panel to turn theanalyzer unit on and off.Note At power-on, the analyzer initializes itself in approximately ten seconds andperforms an exhaustive self-diagnostic that lasts about five seconds. The TriggerLED illuminates during the power-on testing and turns off when testing isfinished. If the diagnostics fail, the trigger LED blinks continuously, indicating ahardware failure. If this occurs, call CATC Customer Support for assistance.3.5 External Interface Breakout BoardThe External Interface Breakout Board is an accessory that allowsconvenient access to several potentially useful standard fast TTL output andinput signals. It also offers a simple way to connect logic analyzers or othertools to the BTTracer Analyzer unit. Four ground pins and one 5-volt pin areprovided.The Breakout Board connects via a ribbon cable to the Data In/Outconnector located on the rear of the analyzer box. Each pin is isolated by a100Ω series resistor and a buffer inside the Analyzer box.Figure 3: Data In/Out ConnectorTable 1 lists the pin-out and signal descriptions for the Data In/Outconnector.Table 1: Data In/Out Connector – Pin-OutPin Signal Name Signal Description1 +5V +5 Volts, 250mA DC source2 TRG IN Trigger Input3 GP IN General Purpose Input4 TRG OUT Trigger Output5 GP OUT General Purpose Output
