1 Introduction

Measurement Computing’s CIO-LAB8-TERM is an educational circuit experimentation board
designed to interface to the CIO-DAS08 AND CIO-DAS08/Jr. Included on the board are circuits
for:

Momentary contact switches (4)
Pull-up resistors (8)
Pull-down resistors (8)
SPST switch (8)
DPST relays (2)
LED bar display (8 LEDs)
Operational amplifier (2)
RC filters (2)
Resistor divider voltage dividers (2)
Resistive shunts (3)
Potentiometers (2)
Semiconductor temperature sensors (2)
Prototype area of 96 sockets. Room for four, 8-pin chips plus discreet components.
Pressure transducer kit location from Force Imaging Technology (kit is not included)
CIO-DAS08, DAS08-PGH, DAS08-AO connector
CIO-DAS08/Jr, DAS08/Jr-AO connector
Power, Ground, ±12V when available from DAS board connector
Sockets for access to all DAS board signals

2 Supporting Texts

There are two supporting texts available to guide your experiments and lab work with the
CIO-LAB8-TERM. These are:
Computer Interfacing: A Practical Guide to Data Acquisition and Control by Dr. William Rigby
and Terry L. Dalton of the University of Michigan, and
Computer Interfacing Laboratory Manual, also by Rigby and Dalton.
Both are published by Prentice Hall and can be purchased from Measurement Computing Corp.

Computer Interfacing Laboratory Manual was written specifically for use with the
CIO-LAB8-TERM. It contains a full semester's experiments employing the circuits on the board.

3 Installation of the CIO-LAB8-TERM

There is really nothing to install. Simply connect the CIO-LAB8-TERM to a compatible data
acquisition board through the 37-pin connector and run the software you intend to use with the
data acquisition board.

CIO-LAB8-TERM is a front-end circuit experimentation board. The effect it has on your
measurements and the way the circuits interact with the software is entirely dependent on the
components you populate the circuits with.

You must understand the principles of electronics and the relationship of the circuits to the
data acquisition board and software, and use to properly apply the circuits.

The circuits on the CIO-LAB8-TERM are not populated. It is up to you to choose the
components to complete the circuits. These choices are not difficult to make, but do require you
to apply the rules of sound electrical engineering practices to choose the components that will
have the desired effect in the circuit.

In general, we cannot choose components for you and do not provide advice of that type over the
phone.

Components such as resistors and capacitors are not available from Measurement Computing. A
good local source of supply may be found at a Radio Shack store or check the yellow pages for
Electronic Components. Another excellent source is DigiKey, an mail order supplier of every
component imaginable. They may be reached at 1-800 DIGIKEY (800-344-4539) and will be
happy to send you a catalog.

4 Component Installation

This section of the manual will help you use the sockets installed on the board to install
components and connect the circuits to the data acquisition board connector (Figure 4-1).

4.1 Circuit Interconnection

Each circuit has sockets for components and for the circuit inputs and outputs. Connection to the
board’s 37-pin connector and to other circuits are made by wires inserted into the sockets. These
jumper wires can be made by stripping 1/4-inch off each end of a 22 or 24AWG sol id wire with
plastic insulation. Use different colors of wire to keep signals separate, such as red for power,
black for ground and green, blue, yellow or orange for analog and digital control signals.

NOTICE: Use only the approved wire gauge in the sockets. Wire larger than 22AWG may
damage sockets necessitating replacement of the socket.

2

4.2 Component Placement

D

Place components for each circuit, such as the resistors needed to complete the resistor voltage
divider circuit shown below, in the labeled socket. The leads of a standard 1/4 watt resistor are
24AWG and are OK to insert into the sockets. If the component has over- or undersized leads,
solder on some waste clippings from 1/4-watt resistors, or use 24AWG wire.

NOTE: Although there holes in the board for every component, we recommend that they not be
used unless some permanent component is decided upon, such as the known value in a college
lab circuit.

CAUTION:

will most surely pull off the solder pad on the component side of the board and damage the
circuit.

Never attempt to remove a soldered-in component by heating and pulling it, you

Please use the sockets only

4.3 Matching the schematic to

and sheet 1 of following schematics.

In the block labeled RESISTIVE

Circuit A is composed of resistors R11
and R12.

Figure 4-1. Voltage Divider Circuit
The two parallel rows of sockets appear on the schematic exactly as they are on the board. The
names of the signals are also exactly as they are written on the board. The pin labeled INPUT is
the high side (+) of the voltage to be divided. The pin labeled OUT is the high side of the
divided signal. Connect it to the A/D input.

The low sides of the voltage-in and voltage-out are connected to PC bus-ground on the board
and require no further connection.

Insert the divider resistors for input voltage in the sockets labeled RES IN for R11 and RES OUT
for R12.

The remainder of the circuitry is self-explanatory. For more information on resistor voltage
dividers please refer to any introductory electronics text.

The other circuits on the board are similarly shown on the schematic, and labeled on the board.
In all cases, where a circuit is shown connected to ground, the ground is PC chassis ground.

5 Force Imaging Technology Pressure Transducer

There is a circuit and a connector on the CIO-LAB8-TERM exclusively for use with a FIT
pressure transducer. FIT sells a kit which contains a pressure transducer, cable and software.
Please contact FIT to learn more about the kit. Call [phone] or fax [phone].
