Overview
This section provides information regarding NetScan hardware. The chapter begins with brief discussions and
illustrations regarding the unit’s front and rear panels. The text is divided into sub-sections which include material
on voltage settings, fuse replacement, memory expansion, and serial interface configuration (RS-232/422). Ethernet
configuration is detailed in Chapter 1.
Additional hardware-related topics are included, such as signal conditioning cards and the optional NetScan
Expansion Chassis.
Front Panel
NetScan’s front panel reveals up to four sets of connectors, one set for each signal conditioning card used. The front
panel contains no switches or other types of control. Each connector row is dependent upon the type of signal
conditioning card used. With different combinations of cards, a variety of setups is possible.
