2.8 Rear Panel Description
From left to right, the UPAS rear panel contains the following components:
Figure 2.1 PETracer EML Rear Panel
USB Type B Host Computer Connector
This connector links the Analyzer to the Host PC for the purpose of transmitting
commands from the PC to the Analyzer and uploading CATC Traces from the Analyzer’s
recording memory to the PETracer software for viewing and analysis or links the
PETrainer Exerciser to the Host PC for the purpose of downloading scripts and controlling
the behavior of the Exerciser.
SFP Sync In and Sync Out Connectors
These connectors allow multiple UPAS 100K chassis to send synchronization and control
messages to one another.
RS-232 40-pin Data Input/Output Connector
This connector links a 40 pin RS-232 cable to an external Breakout Board. The
Breakout Board allows signals to be sent from the Analyzer to an external device such
as an oscilloscope or from an external device to the Analyzer for the purpose of triggering
on an external input. You configure input/output signalling through the Recording Options
dialog box. Breakout Board use is described at the end of this chapter. This connector is
not used by PETrainer EML.
BNC Connectors Ext. In and Ext. Out
These BNC connectors allow the Analyzer to transmit or receive external signals.
External signaling, in turn, can serve two functions:
• Linking of Analyzers: On dual Analyzer systems, the BNC connectors are used to
create a loop for transmitting clocking information and commands between the
Analyzers. This linking allows the two Analyzers to function as a single, logical
Analyzer.
• Triggering: The Ext. In can receive a signal from another device and use that
signal to trigger the end of the recording. Conversely, the Ext. Out connector can be
used to send an output signal from the Analyzer to another device.
The Ext. In and Ext. Out connectors have the same function as the 25 pin RS-232
connector - i.e., they channel input and output signals but do not support the use of a
Breakout Board.
The BNC connectors are not used for the PETrainer Exerciser.
