instruNet provides tens of microvolts
of absolute accuracy instead of tens
of millivolts, at the same cost and at
the same throughput rates as typical
general purpose data acquisition
boards. It does this with a
completely different topology in
which the analog electronics are
close to the sensor in electrically
quiet boxes outside the PC, and
noisy digital electronics are left
inside. The external boxes contain
signal conditioning amplifiers for
each channel and can attach
directly to sensors such as
thermocouples, thermistors, RTDs,
strain gages, load cells, resistance
sources, current sources, and
voltage sources. The box returns
engineering units to the PC
(e.g., °C, volts, amps).

At the heart of the real-time system
is a PCI card (WIN XP/VISTA
(32-bit)/7 (32-bit), PC-card (WIN
XP/VISTA (32-bit)/7 (32-bit) or USB

2.0 (WIN XP SP2/VISTA 32-bit
or 64-bit/7 32-bit or 64-bit) controller
that attaches to a Windows
computer. Each controller contains
a 32-bit microprocessor with 256 KB
of RAM that manages the external
“network” of devices. All real-time
tasks are off-loaded to this
processor so that the host computer
is not burdened with real-time
issues. Each instruNet iNET-100
box provides 16 single-ended/8
differential analog inputs, 8 analog

outputs, and 8 digital I/O lines.
The iNET-100 includes 44 screw
terminals. The iNET-100B version
adds 16 BNCs for analog inputs.
The controllers themselves have
10 counter/timer channels, each
of which can function as a digital
input bit, a digital output bit,
a clock output channel, a pulse
counter, a frequency counter, a
period measurement input, or a
quadrature counter.

Distributed and Expandable

The instruNet system is ideally
suited for distributed measurement
and control systems. The network
cable can extend up to 304.8 m
(1000'). Each controller card in the
PC can connect to up to 8 instruNet
boxes for a total of 128 analog
inputs, 64 analog outputs, and
64 digital I/O. For additional inputs,
multiple controller cards can be
placed in one computer, with the
maximum number of controller
cards limited only by the number
of available slots.

Since each controller card has its
own microprocessor, multiple cards
do not place any additional burden
on the computer. It should be noted
that multiple instruNet boxes on a
single network may degrade the
maximum system throughput of 166
KS/s.
