Introducing the CIO-PDISO16
Overview: CIO-PDISO16 features
The CIO-PDISO16 is a sixteen channel-isolated high voltage digital input and sixteen relay output interface
board. You can use the CIO-PDISO16 for control and sensing applications where high voltages need to besensed or controlled.
Caution! High voltages are present on the CIO-PDISO16 when you have connected high voltage inputs or
outputs to the CIO-PDISO16 connector. Use extreme caution! Never handle the CIO-PDISO16
when signals are connected to the board through the connector.
Never remove the protective plates from the CIO-PDISO16.
The sixteen inputs are optically-isolated (500 V) inputs that can be read back as a single byte. The inputs are notpolarity sensitive, and may be driven by either AC (50 - 1000 Hz) or DC. Each input has a switchable low-passfilter with a time constant of 5 ms (200 Hz).
Outputs are from sixteen electromechanical relays. All relays have FORM C connections. The relays arecontrolled by writing to two 8-bit ports. The relay control register can be read back from the same ports.
Signal conditioning installed
The CIO-PDISO16 is a combination digital I/O board with signal conditioning installed. Most accessory boards
provide signal conditioning or easy-to-access signal termination. The CIO-PDISO16 does not require additionalsignal conditioning.
Caution! We recommend NOT using screw terminal boards with the CIO-PDISO16. The CIO-PDISO16 isintended to sense and control high voltages. If you use a screw terminal board, you will expose
yourself and others to those high voltage signals. We recommend that you construct a safe cable tocarry your signals directly from your equipment to the CIO-PDISO16 connector.

Software features
For information on the features of InstaCal and the other software included with your CIO-PDISO16, refer tothe Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.

Installing the CIO-PDISO16

Unpacking the board
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-PDISO16 from its packaging, ground yourself using a wrist strap or bysimply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately byphone, fax, or e-mail:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.
Fax: 508-946-9500 to the attention of Tech Support
Email: techsupport@mccdaq.com

Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-SoftwareQuick-Start.pdf.

Configuring the CIO-PDISO16
The CIO-PDISO16 has one base address switch, two sets of input filter switches, and one wait state jumper
which you must set before installing the board in your computer. The InstaCal calibration and test program
included with the CIO-PDISO16 will show you how to set the switches. Run InstaCal before you open yourcomputer and install the board. The CIO-PDISO16 is shipped with the factory-default settings listed below.

Installing the CIO-PDISO16

Base address switch
The base address switch sets the starting I/O location where the CPU can access the registers of the CIOPDISO16. The factory default is 300h (768 decimal).
Before you install the CIO-PDISO16 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 2 shows the settings for the factory-default baseaddress of 300 hex.

Figure 2. CIO-PDISO16 base address switches

In the default configuration shown in Figure 2, 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 jumper
The CIO-PDISO16 board has a wait state jumper which you can set to enable an on-board wait state generator.
A wait state is an extra delay injected into the processor's clock via the bus. This delay slows down theprocessor when the processor addresses the CIO-PDISO16 board so that signals from slow devices (chips) will
be valid.
The factory default is wait state disabled (Off). You will probably never need the wait state because PC
expansion slot busses are limited to 8 or 10 MHz. If you get intermittent operation, try enabling the wait state tosee if that solves the problem.

Installing the CIO-PDISO16

AC input filter switches
The CIO-PDISO16 board has two sets of eight individual, optically isolated (500 V) inputs that can be readback as a single byte. The inputs are not polarity sensitive, and may be driven by either AC (50 - 1000 Hz) orDC.
Each input has a switchable low-pass R-C filter having a time constant of 5 ms (200 Hz). The filters must be
used for AC inputs, and should be used for DC inputs. A typical switch is shown in Figure 4.
7 6 5 4 3 2 1 0
0NFigure 4. AC input filter switches (typical)

Unless you have reason to turn off a filter, you should leave it on (switch up). With the filter on, an AC voltage
on the input will produce a constant high signal.
Caution! High voltages are present on the CIO-PDISO16 when you have connected high voltage inputs or
outputs to the CIO-PDISO16 connector. Use extreme caution! Never handle the CIO-PDISO16
when signals are connected to the board through the connector.
Never remove the protective plates from the CIO-PDISO16.

Installing the CIO-PDISO16
After you configure the board's switches and jumper, you can install the CIO-PDISO16 into your computer. To
install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installingthe software.
1.

Turn your computer off, open it up, and insert your board into an available ISA slot.

2.

Close your computer and turn it on.

3.

To test your installation and configure your board, run the InstaCal utility you installed in the previous
section. Refer to the Quick Start Guide that came with your board www.mccdaq.com/PDFmanuals/DAQSoftware-Quick-Start.pdf for information on how to initially set up and load InstaCal.

CIO-PDISO16 User's Guide

Installing the CIO-PDISO16

Do not use exposed-screw terminal boards if your field voltage is more than 24 volts. Using a screw terminal
board with high voltage inputs or outputs exposes you and others to those high voltage signals. Construct a safe
cable to carry your signals directly from your equipment to the CIO-PDISO16 connector.
Caution! High voltages are present on the CIO-PDISO16 when you have connected high voltage inputs or
outputs to the CIO-PDISO16 connector. Use extreme caution! Never handle the CIO-PDISO16
when signals are connected to the board through the connector.
Never remove the protective plates from the CIO-PDISO16.

CIO-PDISO8 compatibility
The C50-37F-x cable converts the CIO-PDISO16 to a CIO-PDISO8 compatible D-type connector. The
C50-37F-x cable has a 50-pin header connector at one end and a 37-pin female D-sub connector at the otherend.
