Chapter 1

Introducing the CIO-DIO96

Overview: CIO-DIO96 features

The CIO-DIO96 is a 96-bit digital I/O board with four 82C55 parallel-interface chips. The board provides the

96 bits in 24-bit groups based on the 82C55 specification.

Each 82C55 chip controls 24 CMOS/TTL-compatible digital I/O pins. Each 24-bit group is divided into three eight-bit ports, or two 8-bit ports and two 4-bit ports. Each port is programmable for input or output.

All I/O bits are set to input mode (high impedance) on power up and reset. Locations are available for installing pull-up or pull-down resistors.

All signals pass through a 50-pin connector.

Software features

Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf

.

Configuring the base address switch

The CIO-DIO96 employs the PC bus for power, communications and data transfer. As such, it draws power from the PC, monitors the address lines and control signals, responds to its I/O address, and receives and places data on the eight data lines.

The CIO-DIO96 has one bank of base address-select switches, and one wait-state jumper. Verify their settings before installing the board in your computer.

Base address switch

The easiest way to set the base address is to let InstaCal show you the correct settings. However, if you are already familiar with setting ISA base addresses, you may use the base address switch description below to guide your base address selection.

The base address is the starting location that software writes to when communicating with the CIO-DIO96. A set of DIP switches is used to set the base address. By placing the switch down, the CIO-DIO96 address decode logic is instructed to respond to that address bit. A complete address is constructed by calculating the HEX or decimal number which corresponds to all the address bits the board has been instructed to respond to.

The board is shipped with the base address set to 300 hex (see Figure 1

)

. Unless there is already a board in your system that uses address 300 hex (768 decimal), leave the switches as they were set at the factory.

You can set the base address switch to any address in the range of 000-3F8. If you are not using IBM prototyping cards or another board which occupies these addresses, 300-31Fh are also free to use.

Addresses not specifically listed, such as 390-39Fh, are not reserved and may be available. Check your computer for other boards which may use I/O addresses.

Wait state jumper

The CIO-DIO96 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 the processor when the processor addresses the CIO-DIO96 board, so that signals from slow devices (chips) are valid.

The jumper is shown in

Figure 2 configured for OFF (wait state is disabled).

STATE

Figure 2. Wait state jumper

The wait state generator is only active when the CIO-DIO96 is being accessed. Your PC will not be slowed down in general by using the wait state.

Because all PC expansion board buses are slowed to either 8 MHz or 10 MHz, the wait state generally is not required. If you experience sporadic failures, try enabling the wait state generator.

Figure 3. P1 AND P2 pin out

All the digital inputs and outputs are TTL. Under normal operating conditions, the voltages on the I/O pins range from near 0 volts for the low state, to near 5 volts for the high state. The voltages and currents of external devices usually exceed these values. Because of this, external relays are usually employed to handle higher current and voltage loads.

In addition to load matching, digital signal sources often need to be filtered or "de-bounced". Refer to the Guide

to Signal Connections for information on digital interfacing. This document is available at www.mccdaq.com/signals/signals.pdf

Functional Details

Signal level control

The digital I/O bits on the CIO-DIO96 are 8255 CMOS TTL. The 82C55 digital I/O chip initializes all ports as inputs on power- up and reset. A TTL input is a high impedance input. If you connect another TTL input device to the 82C55 it could be turned ON or OFF every time the 82C55 is reset.

All I/O bits are set to input mode on power up and reset. If you are using the board to control items that must be

OFF on reset, install pull-down resistors. The CIO-DIO96 has open locations where you can install Single

Inline Packages (SIP) resistor networks in either pull-up or pull-down configurations.

You can install pull-up and pull-down resistor SIP packs at each port. The positions are labeled

RN1

through

RN6

on the board. When installed, the SIP establishes either a high or low logic level at each of the I/O lines on the port.

To safeguard against unwanted signal levels, the devices being controlled by the CIO-DIO96 board should be tied low or high as required by a 2.2K

Ω resistor. In a 2.2K eight-resistor SIP pack, one side of all of the resistors is connected to a single common point and brought out to a pin. The common line, usually marked with a dot or line, is at one end of the SIP. The remaining resistor ends are brought out to the other eight pins

(refer to Figure 5).

CIO-DIO96 User's Guide Functional Details

To pull-up lines, orient the SIP with the common pin (dot) toward the

HI

end; to pull-down, install the resistor with the common pin in the

LO

hole.

When installing pull-up and pull-down resistor SIP packs, we recommend using 2.2K, eight-resistor Single

Inline Packages (MCC part number SP-K2.29C). Use a different value only if necessary.

Unconnected inputs float

Unconnected inputs typically float high, but not reliably. If you are using a CIO-DIO48H for input and have unconnected inputs, ignore the data from those lines. You do not have to terminate input lines. Unconnected lines will not affect the performance of connected lines. Mask out any unconnected bits in software.

Digital I/O Isolation

To provide external signal conditioning and isolation, you can connect the CIO-DIO96 to a CIO-ERB24 or

SSR-RACK24. The CIO-ERB24 provides 24 Form C electromechanical relays. The SSR-RACK24 is a mounting rack for 24 solid-state relays.

The CIO-DIO96 provides digital I/O in groups of 48-bits. Many relay and solid-state relay (SSR) racks provide only 24-bits of digital I/O. You can configure the CIO-ERB24 relay output board and SSR-RACK24 I/O module rack in a daisy chain configuration to use all of the digital I/O bits provided by the CIO-DIO96 board.

An example of this configuration scheme is shown below.

Programming and Developing Applications

After following the installation instructions in Chapter 2, your board should now be installed and ready for use.

In general there may be no correspondence among registers for different boards. Software written at the register level for other models will not function correctly with your board.

Programming languages

Measurement Computing's Universal Library provides access to board functions from a variety of Windows programming languages. If you are planning to write programs, or would like to run the example programs for

Visual Basic

or any other language, please refer to the Universal Library User's Guide (available on our web site at www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf

).

Packaged applications programs

Many packaged application programs now have drivers for your board. If the package you own does not have drivers for your board, please fax or e-mail the package name and the revision number from the install disks.

We will research the package for you and advise how to obtain drivers.

Some application drivers are included with the Universal Library package, but not with the application package.

If you have purchased an application package directly from the software vendor, you may need to purchase our

Universal Library and drivers. Please contact us by phone, fax or e-mail:

ƒ Phone: 508-946-5100 and follow the instructions for reaching Tech Support.

ƒ Fax: 508-946-9500 to the attention of Tech Support

ƒ Email: [email protected]

Register-level programming

You should use the Universal Library or one of the packaged application programs mentioned above to control your board. Only experienced programmers should try register-level programming.

If you need to program at the register level in your application, refer to the Register Map for the

CIO-DIO48, CIO-DIO48H, CIO-DIO96, and CIO-DIO192. This document is available on our website at www.mccdaq.com/registermaps/RegMapCIO-DIO-Series.pdf
