The world we live in is full of variables we want to
measure. These include weight, temperature, pressure,
humidity, speed and fluid level. These variables are
continuous
and their values may be represented by a
voltage. This voltage is the analog of the physical varia-
ble. A device which converts a physical, mechanical or
chemical quantity
to a voltage is called a sensor.
Computers do not understand voltages: They under-
stand bits. Bits are digital signals. A device which con-
verts voltages to bits is
an analog-to-digital converter.
Our AIM16 (Analog Input Module) is a
16 input analog-
to-digital converter.
The goal of Connecticut microComputer
in designing
the
DAM SYSTEMS is to produce easy to use, low cost
data acquisition modules for small computers.
As the
line grows
we will add control modules to the system.
These acquisition and control modules will include
digital input sensing (e.g. switches), analog input sens-
ing (e.g. temperature, humidity), digital output control
(e.g. lamps, motors, alarms), and analog output control
(e.g. X-Y plotters, or oscilloscopes).
The
AIM 16 is a 16 Channel analog to digital converter
designed to work with most microcomputers. The
AIM16 is connected to the host computer through the
computer's 8 bit input port and 8 bit output port, or
through one of the
DAM SYSTEMS special interfaces.
The input voltage range is 0 to 5.12 volts. The input
voltage
is converted to a count between 0 and 255 (00
and
FF hex). Resolution is 20 millivolts per count. Ac-
curacy
is 0.5% ± 1 bit. Conversion time is less than 100
microseconds per channel. All
16 channels can be
scanned in less than 1.5 milliseconds.
Power requirements are 12 volts
DC at 60 ma,
The POW1 is the power module for the AIM16. One
POW1 supplies enough power for one AIM16, one
MANMOD1, sixteen sensors, one
XPANDR1 and one
computer interface. The
POW1 comes in an American
version
(POW1 a) for 110 VAC and in a'European ver-
sion
(POW1 e) for 230 VAC.

Connectors

The AIM16 requires connections to its input port
(analog inputs) and its output port (computer inter-
face). The ICON (Input CONnector)
is a 20 pin, solder
eyelet, edge connector for connecting inputs to each of
the
AIM 16's 16 channels. The OCON (Output CONnec-
tor) is a
20 pin, solder eyelet edge connector for con-
necting the computer's input and output ports to the
AIM16.
The MANMOD1 (MANifold MODule) replaces the
ICON. Ithas screw terminals and barrier strips for all 16
inputs for connecting pots, joysticks, voltage sources,
etc.
CABLE A24 (24 inch interconnect cable has
an inter-
face connector
on one end and an OCON equivalent on
the other. This cable provides connections between the
DAM SYSTEMS computer interfaces and the AIM16 or
XPANDR1 and between the XPANDR1 and up to eight
AIM16s.

The XPANDR1 allows up to eight AIM16 modules to be
connected to a computer at one time. The XPANDR1 is
connected to the computer in place of the AIM16. Up to
eight AIM16 modules are then connected
to each of the
eight ports provided using a CABLE A24 for each
module. Power for the
XPANDR1 is derived from the
AIM16 connected to the first port.

TEMPSENS
This module provides two temperature probes for use
by the AIM16. This module should
be used with the
MANMOD1 for ease of hookup. The
MANMOD1 will
support up to 16 probes (eight TEMPSENS modules).
Resolution for each probe
is 1°F.
