Before installing the CIO-DAS801, 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 CIO-DAS801 board.

Base address switch
Before you install the CIO-DAS801 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.

Input configuration
You can configure each analog channel for differential or single-ended input. You can set the input of eachchannel using the bank of switches labeled S2 (0 through 7) on the board. These switches correspond tochannels 0 to 7 of the analog inputs.
The switches are set by default for differential input. Differential inputs are 3-wire analog hookups consistingof a signal high, signal low and chassis ground. The benefits of differential inputs are the ability to reject noise
which affects both signal high and low, and the ability to compensate for ground loops or potentials between
signal low and chassis ground.
Although differential inputs are often preferable to single ended inputs, the floating nature of a differential
input can make getting an accurate reading difficult. In those cases, the CIO-DAS801 inputs can be converted
to single-ended or modified differential.

CIO-DAS801 User's Guide

Installing the CIO-DAS801

The CIO-EXP16 and CIO-EXP32 were designed to interface to a single-ended input. Failure to set the switches
to single-ended when an EXP is connected results in floating, unstable readings from the EXP.
There are two ways to configure the analog inputs:

Set the bank of eight DIP switches on the jumper block labeled S2 located near the I/O connector.
Position the switches in the OFF position (down) to configure the input for differential mode (default).
Position the switches in the ON position (up) to configure the input for single-ended mode.

This package of 10K resistors provides a reference to ground for each of the eight Low Input lines. This
type of input behaves like a single-ended input since there is a reference to ground and floating sources
may be measured.
Figure 4 shows one analog input line with the SIP resistor installed. When the SIP resistor package isinstalled, all eight analog inputs are single-ended.

Interrupt level
In order to take advantage of high speed transfers, you must provide the board with an interrupt that is not usedby other devices in your computer. Use the jumper block labeled IR (above the PC bus interface) to select aninterrupt level between 2 and 7, or to disable interrupts (X). By default, the board is shipped with no interrupt
level set (the jumper is in the 'X' position). Figure 5 shows the interrupt level set for IRQ 5.

Figure 5. Interrupt level select jumper

Set the interrupt level jumper if your software requires it. The Universal Library and other programs which takeadvantage of the REP-INSW high speed transfer capability of the board require an interrupt. If you set theinterrupt jumper, check your PC's current configuration for interrupt conflicts. Refer to the table below for
typical IRQ assignments.

Wait state jumper
Enable the wait state jumper if you have a computer with an I/O bus transfer rate which is too fast for the CIODAS801, or if the board fails sporadically in random ways.
To enable the wait state, set the jumper labeled WS1 to the ON position. Enabling the wait state causes the
personal computer's bus transfer rate to slow down whenever the CIO-DAS801 is written to or read from. Thisjumper is shown in Figure 6 configured for OFF (wait state is disabled).

Functional Details
Analog inputs
Analog inputs on the CIO-DAS801 are designed to accept voltage signals for measurement.
The analog inputs may be configured in three different ways:

True differential inputs; for sources with a separate ground, common to the PC.
Pseudo-differential inputs used for floating sources has noise rejection capability
Single ended inputs; also used for floating sources.

Caution! Using a voltmeter, measure the AC and DC voltage between the ground signal at the signal source
and the PC. Place the red probe on the PC ground and the black probe on the signal ground. If
there is more than 10 volts, do not connect the CIO-DAS801 to this signal source because you
will not be able to make any reading. If there is more than 30 volts, DO NOT connect this signal
to the board because it will damage the board and possibly the computer.
Use great care when measuring any voltage. Voltages over 30 V can be dangerous to your health.

Single-ended inputs
A single ended input is two wires connected to the CIO-DAS801; a channel high (CH# HI) and a Low levelground (LLGND). The LLGND signal must be the same ground the PC is on. The CH# HI is the signal
voltage. Single-ended mode is selected via switch S2 on the board (refer to Input configuration on page 10 for
more information.)

Floating differential
A floating differential input is two wires from the signal source and a 10K ground reference resistor installed at
the CIO-DAS801 input. The two signals from the signal source are Signal High (CH# HI) and Signal Low(CH# LO). The reference resistor is connected between the CIO-DAS801 CH# LO and LLGND pins. This isaccomplished with the installation of the SIP resistor pack.
A floating differential hookup is handy when the signal source is floating with respect to ground, such as abattery, 4-20 mA transmitter or if the lead lengths are long or subject to EMI interference. The floating
differential input will reject up to 10 V of EMI on the signal wires.
Caution! Verify that the signal source really floating. Check it with an ohmmeter before risking the CIODAS801 and the PC.

Fully differential
A differential signal has three wires from the signal source. The signals are Signal High (CH# HI), Signal Low(CH# LO) and Signal Ground (LLGND).
A differential connection allows you to connect the CIO-DAS801 to a signal source with a ground that isdifferent than the PC ground, but less than 10 V difference, and still make a true measurement of the signal
between CH# HI and CH# LO.
Example: A laboratory instrument with its own wall plug. There are sometimes voltage differences in wall
GND between outlets.

CIO-DAS801 User's Guide

Functional Details

Digital inputs and outputs
All the digital inputs and outputs on the CIO-DAS801 are TTL level. TTL is an electronics industry term, shortfor Transistor Transistor Logic, with describes a standard for digital signals which are either at TTL low or
TTL high; levels which are detected by all other TTL devices.
The CIO-DAS801 has three digital inputs and four digital outputs. The digital inputs are buffered by a registeron the board. Each time the register is read, the current high/low state of the digital I/O lines is obtained. The
digital outputs are controlled by a register on the board and are updated each time the register is written to. Thelines are pulled high so a logical-one is read if no signal is connected to an input.
The digital lines also are used to control external EXP boards (all four outputs) and to trigger and gate A/D
conversions (DIn 1).

Counter/timer circuit
The CIO-DAS801 has an 82C54 counter timer which can be used to perform the following tasks:Pace analog conversions
Measure frequency
Count events
Time intervals

The software to support the timer is in the Universal Library. The connections to the hardware are explained
here. For detailed information on the 82C54 registers, refer to the 82C54 data sheet atwww.mccdaq.com/PDFmanuals/82C54.pdf.
The 82C54 contains three 16-bit counters (CTR0, CTR1, and CTR2). CTR1 and CTR2 are dedicated to thepacing of analog to digital conversions. CTR1 and CTR2 are available for other tasks when not in use by the
A/D, but are limited to some extent by the wiring and access to I/O pins. CTR0 is available for your use.
Figure 8 shows the connections to the counters. It also shows the 82C54 functions, I/O pins and how these areconnected on the CIO-DAS801.
