Chapter 1

Introducing the CIO-DAS48-PGA
Overview: CIO-DAS48-PGA features
The CIO-DAS48-PGA provides 48 single-ended analog inputs or 24 differential inputs. The input mode isswitch-selectable. Input ranges are software-selectable as either bipolar or unipolar:

Bipolar: ±10 V, ±5 V, ±2.5 V, ±1.25 V, and ±0.625 V
Unipolar: 0 to 10 V, 0 to 5 V, 0 to 2.5 V, and 0 to 1.25 V

In differential mode, up to three optional 10 K SIPs can be installed to provide ground reference to the CH LO
inputs. The SIPs are installed in banks of 8 inputs each.
An optional current measurement conversion kit (MCC part number CIO-DAS48-ISIP) is available forconverting the 24 differential voltage measurements inputs into 24 current measurement inputs. The kit
contains six, four-resistor-SIPs that you install on the board. You set the board's input type to current with an
on-board jumper.
A DC/DC converter supplies stable ±15 V power to the analog circuitry. It is possible to construct the board
without the DC/DC converter. This reduces the cost but limits the ranges of analog inputs. It is available withorders of 10 or more units.
You can enable a wait state generator with an on-board jumper.

Software features
For information on the features of InstaCal and the other software included with your CIO-DAS48-PGA, referto the Quick Start Guide that shipped with your device.

Configuring the CIO-DAS48-PGA
The CIO-DAS48-PGA has a base address switch, an input mode switch, an input type jumper, and a wait state
jumper which you must set before installing the board in your computer. Configure the input type jumper only
if you have the voltage to current input conversion kit.
The InstaCal calibration and test program included with the CIO-DAS48-PGA will show you how to set theswitches and jumpers. Run InstaCal before you open your computer and install the board. The CIO-DAS48PGA is shipped with the factory-default settings listed below.

Before installing the CIO-DAS48-PGA, verify that the board is configured with the settings that you want.
Review the following information to change the default configuration of a jumper or switch on the CIODAS48-PGA board.

Base address
Before you install the CIO-DAS48-PGA in your computer, set the base address by using the dip switch labeled
ADDRESS located on the board. The easiest way to set the base address switch is to let InstaCal show you thecorrect settings. However, if are already familiar with setting ISA base addresses, you may use the base address
switch description below to guide your base address selection.
Unless there is already another board in your system using address 300 hex (768 decimal), leave the switches as
they are set at the factory. The example shown in Figure 1 shows the settings for the factory-default baseaddress of 300 hex.

Figure 1. Base address switches

In the default configuration shown in Figure 1, addresses 9 and 8 are DOWN, and all others are UP.
Address 9 = 200 hex (512 decimal) and address 8 = 100 hex (256 decimal); when added together they equal
300 hex (768 decimal).
Disregard the numbers printed on the switch
When setting the base address, refer to the numbers printed in white on the printed circuit board.

Wait state
Enable the wait state jumper if you have a computer with an I/O bus transfer rate which is too fast for the CIODAS48-PGA, or if the board fails sporadically in random ways.
To enable the wait state, set the jumper to the ON position. This jumper is OFF by default. Enabling the waitstate causes the personal computer's bus transfer rate to slow down whenever CIO-DAS48-PGA is written to orread from. This jumper is shown in Figure 2 configured for OFF (wait state is disabled).

Functional Details
Single ended inputs
Single-ended inputs are two-wire connections between the signal source and the A/D board. A single wire
carries the signal, and is connected from the signal source to Channel n HI. The ground from the signal sourcemust be connected to LLGND (pins 49 or 50).

Differential inputs
Differential inputs are 3-wire analog hookups consisting of a signal high, signal low and chassis ground. The
signal source high is connected to Channel n HI, the signal source low is connected to Channel n LO, and thesignal source GND is connected to LLGND.
The benefits of differential inputs are the ability to reject noise which affects both signal high and low, and theability to compensate for ground loops or potentials between signal low and chassis ground.

Modified differential
Modified differential inputs for voltage measurements provide much of the environmental-noise immunity andcommon mode rejection of fully differential inputs with the convenience of a two wire hookup.
Although differential inputs are often preferable to single-ended inputs, there are occasions when the floating
nature of a differential input can prevent making a valid reading. In those cases, the CIO-DAS48-PGA inputs
can be converted to modified differential.
Near the 50-pin connector on the board are positions for optional Single Inline Packages (SIP) of 10 K
resistors. Installing the SIP in RN7, RN8 and RN9 converts the analog inputs from fully differential to modified
differential with a 10 K reference to ground.
Notes: All three sips must be installed. It is not possible to mix channels.

After the SIPs are installed, signal connections require on Signal Source Hi be connected to Channel n HI andsignal source low be connected to Channel n LOW. No connection to LLGND is needed.
Special instructions and solder are packaged with the 10K SIP. Follow the installation instructions carefully anduse the solder provided. Use of other solder, or failure to follow instructions will probably result in adegradation of the analog input's accuracy and will require out-of-warranty repair.

Current loop measurements
If you are configuring a CIO-DAS48-PGA for current measurements, do the following operations:1.

Remove (clip off) the SIPs from RN7, RN8, and RN9, if installed. These SIPs must not be installed if theboard is to be used for current measurement.

2.

Install the resistor "CIO-DAS48-ISIP" kit. Install ISIPs in RN1, RN2, RN3, RN4, RN5, and RN6.
Special instructions and solder are packaged with the CIO-DAS48-ISIP kit. Follow the installation
instructions carefully and use the solder provided. Use of other solder, or failure to follow instructions willprobably result in a degradation of the analog input's accuracy and will require out-of-warranty repair.

13

CIO-DAS48-PGA User's Guide

Functional Details

The selection of the ISIPs is critical. Variations in either value or tolerance from those supplied in the
CIO-DAS48-ISIP will result in inaccurate measurements.
3.

Set the input type jumper to the "I" position (see page Error! Bookmark not defined.).

4.

Set the DIFF/SINGLE switch to the "24 DIFF" position (see page 11).

5.

Install the board and run the InstaCal calibration procedure for current mode.

After installation, the inputs are committed to current measurement and cannot be used for voltage
measurement.
To restore the inputs to voltage measurement remove the ISIPs (clip off the SIPs). If you want to de-solder
the SIPs, you must return the board to the factory.
If you want to re-install the 10k SIPs in RN7, RN8, and RN9 (to have ―Modified-Differential‖ inputs), youmust return the board to the factory.

It is not possible to install only a portion of the ISIPs and have a mixture of current and voltage inputs. You
must install all six SIPs from the CIO-DAS48-ISIP package, and set the input type jumper to the "I" position.
