WavePort/PE Devices
Overview
The following block diagram serves to provide a general understanding of WavePort/PE devices. Detailed
information regarding such items as the signal and power modules, indicator lights, and the unit fan are
included later in this chapter.
WavePort/PE, Simple Block Diagram
The Notebook Power receptacle on WavePort’s cover plate is “LIVE” whenever WavePort is
connected to a “live” AC power source. The Module Power Switch can not be used to turn
off the Notebook Power Receptacle.
From the diagram we can see that WavePort/PE16* consists of:
• Two Dynamic Signal Input Modules (Module 2 and Module 1).* Both modules provide for 8 input
channels (through BNC connectors), an Excitation Source Out BNC, and a Filter Clock In BNC. The
dynamic signal input modules are based on WBK14 architecture.
• One WaveBook Module. This module provides for 8 analog channel inputs through BNC connectors
and a Pulse input.
• A 65 watt, 16 VDC Power Supply and Internal UPS (Uninterruptible Power Supply) System
• Two 25-pin connectors (DB25). One for connecting to the Notebook’s parallel port and another for
connecting to Digital I/O, External Clock, and TTL Trigger signals
• Three electrical connectors: DC Power Input, AC Power Input, and AC Auxiliary Output
• Three Indicator Lights: for “Battery” Status, indication of “Modules On,” and “Fan” On
• Fan, variable speed to provide system cooling
*WavePort/PE 8 has one Dynamic Signal Input Module (Module 1).
