Limited Warranty

Sensoray Company, Incorporated (Sensoray) warrants the Model 6 1/7 0 hardware to be free from

defects in material and workmanship and perform to applicable published Sensoray specifications for

two years from the date of shipment to purchaser. Sensoray will, at its option, repair or replace

equipment that proves to be defective during the warranty period. This warranty includes parts and

labor.

The warranty provided herein does not cover equipment subjected to abuse, misuse, accident, alteration,

neglect, or unauthorized repair or installation. Sensoray shall have the right of final determination as to

the existence and cause of defect.

As for items repaired or replaced under warranty, the warranty shall continue in effect for the remainder

of the original warranty period, or for ninety days following date of shipment by Sensoray of the

repaired or replaced part, whichever period is longer.

A Return Material Authorization (RMA) number must be obtained from the factory and clearly marked

on the outside of the package before any equipment will be accepted for warranty work. Sensoray will

pay the shipping costs of returning to the owner parts that are covered by warranty.

Sensoray believes that the information in this manual is accurate. The document has been carefully

reviewed for technical accuracy. In the event that technical or typographical errors exist, Sensoray

reserves the right to make changes to subsequent editions of this document without prior notice to

holders of this edition. The reader should consult Sensoray if errors are suspected. In no event shall

Sensoray be liable for any damages arising out of or related to this document or the information

contained in it.

EXCEPT AS SPECIFIED HEREIN, SENSORAY MAKES NO WARRANTIES, EXPRESS OR

IMPLIED, AND SPECIFICALLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR

FITNESS FOR A PARTICULAR PURPOSE. CUSTOMER’S RIGHT TO RECOVER DAMAGES

CAUSED BY FAULT OR NEGLIGENCE ON THE PART OF SENSORAY SHALL BE LIMITED

TO THE AMOUNT THERETOFORE PAID BY THE CUSTOMER. SENSORAY WILL NOT BE

LIABLE FOR DAMAGES RESULTING FROM LOSS OF DATA, PROFITS, USE OF PRODUCTS,

OR INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF ADVISED OF THE

POSSIBILITY THEROF.

Special Handling Instructions

The Model 6 1/7 0 circuit boards contains CMOS circuitry that is sensitive to Electrostatic Discharge

(ESD).

Special care should be taken in handling, transporting, and installing the board to prevent ESD damage

to the board. In particular:

Do not remove the circuit board from its protective anti-static bag until you are ready to configure

the board for installation.

Handle the circuit board only at grounded, ESD protected stations.

Remove power from the PCI system before installing or removing the circuit board.

1. Introduction

The Sensoray models 6 1/7 0 are 7 channel digital I/O cards. The features include:

7 digital I/O channels.

64 channels have edge detection and interrupt capability.

8 channels have input latch and output enable capability.

64 I/O channels are grouped in eight blocks of eight channels. 8 I/O channels are grouped in two

blocks of four channels. Each block may be programmed as inputs or outputs.

The 6 0 is a PCI card whereas the 7 1 is a Compact PCI card. Except for where otherwise specified, this

document applies to both models.

The board is powered from the 5V supply of the PCI bus. No auxiliary power supplies are required. Low

power circuitry is used to minimize system power consumption and enhance reliability.

A high-density connector on the card’s front panel is provided for connecting the I/O channels to

external circuitry. A solid state relay board (see Sensoray model 7 0RB) will often be used to facilitate

connections to real world circuits.

2. Installation

The installation of the board into a PCI or Compact PCI system is straight forward as no special

adjustment (jumpers) are required.

3. Reset

After a system reset or at power up the board is in its default state

Global interrupt enable (GIE) is disabled

Channel interrupt enables are cleared (disabled)

Event capture enables are indeterminate

Edge selections are indeterminate

All I/O channels are all set to input mode

Output registers are indeterminate

Channel 64 through 71 are set to simple I/O mode (no latching/output enable)

Light emitting diode ‘D1’ will be on (controlled by LOE bit which is clear)

4. Device and Vendor Identification

This is the information that identifies a board in the system.

Device ID: 9050 Sub Device ID: 6000

Vendor ID: 10B5 Sub Vendor ID: 0001

5. Digital I/O Interface

Note: Any examples referred to in this manual are written in Visual Basic format. Look at the C &

Visual Basic samples included with the board for more examples.

5.1 Overview

The board provides 7 digital I/O channels. 64 channels have edge detection capability. 8 channels have

input latch and output enable capability.

The 64 edge detection capable channels (channels 0-63) are divided into groups of eight. Each group can

be set as inputs or outputs by setting its corresponding data direction register (DDR).

If edge capture is desired, the arm capture register can be enabled for any particular input channel. In

addition, either capture on a positive or negative going edge can be selected.

A capture event can generate an interrupt if a channel’s corresponding interrupt enable bit is set. If an

interrupt occurs, a channel interrupt flag will be set such that the user can determine the source.

The eight remaining I/O channels (channels 64-71) are divided into two groups of four. Each group can

be set as inputs or outputs by setting its corresponding data direction register (DDR).

A latch/output enable (LOE) mode is available for channels 64 through 71. Setting the latch enable

The LOE mode allows a user to latch the data inputs (channels 64 through 71) by asserting the LATCH

input line. The data can be then read at the user’s convenience. In addition, the outputs in this mode are

tri-stated unless the user asserts the OUTEN input line.
