Cameras
The camera views the part to be inspected and electronically converts the scene in
its field of view into an analog signal. Then, the signal is converted into a digital
signal that is processed by the Acuity Vision Accelerator.
Solid state cameras are used. They are powered by the Acuity 1000 Vision
Accelerator and must be compatible with the Acuity 1000 Vision Accelerator.
Cameras that are used for strobe lighting applications have been specially
modified by RVSI Acuity CiMatrix.
Refer to Chapter 3, “Combination I/O Board” for pinout diagrams and
information.

Strobe & Sensor
When choosing your part sensor, you must consider the time interval between the
part passing into the sensing zone and an electrical signal being generated. When
there is a large variation in process speed, considerable apparent motion of the
part within the FOV may result. The Acuity 1000 Vision Accelerator can
compensate for this motion over a considerable range. However, the sensor
should be fast enough to minimize this apparent shift.
To connect your sensor and strobe, refer to Figure 2–10 and Figure 2–12.

System Components
For continuous motion or high-speed indexing applications, a sensor and strobe
will be required to freeze each part before the image can be acquired. The strobe
unit may include a fiber-optic light pipe.

Combination I/O Board

Overview
The Combination I/O Board provides up to 16 discrete I/O points, 4 Strobe and
Sensor connections, and 8 channels for analog outputs, as shown in Figure 3–1.
Using a Combination I/O Board, the Acuity 1000 Vision Accelerator can
communicate with other devices. For example, you can have three input modules
that provide input signals to the Acuity 1000 Vision Accelerator, and you can
have four output modules that send signals to external control devices.

•
Digital I/O—This is used to connect the Combination I/O Board to the
Acuity Vision Processor and provides 16 I/O points. Digital I/O allows you
to connect to switches, lights, controls, PLC’s, etc., and uses G4 type optos.
•
Sensor In—This is used if you need to connect a parts sensor to your Acuity
1000 Vision Accelerator.
•
Strobe Out—This is used if you run the Acuity 1000 Vision Accelerator in a
strobed application and need to connect your strobe to the Strobe Out
connector.
•
Analog Output—This has 8 analog outputs that are jumper-selectable for
0-5V or 0-10V outputs with 6-bit (64 level) of resolution. The last two
Digital I/O points are used to control the analog outputs, which are typically
used for controlling light sources. There are 14 Digital I/O ports available (114) when Analog Output is selected by SW1.
Acuity 1000 Hardware Guide
Rev A, July 2001
Overview
I/O Connection from PC—Connects the Combination I/O Board to the
Camera I/O Card via a 50-pin ribbon cable. You can attach your own
industry standard I/O board to the I/O Connector. Only 16 bits of I/O are
available. RVSI Acuity CiMatrix suggests that you use optically-isolated
I/O, such as Opto 22 type optos.
•
VREF—When disconnected, the sensor reference voltage defaults to TTL
levels (1.4V). By applying a voltage between VREF and VREF_GND, the
reference voltage will change to VREF/2. VREF should be greater than or
equal to 5V.
Note: You must remove the 12V Sensor Power Jumper (JMP1) from the
Camera I/O Card before installing your own I/O board.

There is a Sensor/Strobe connector JS, as shown in Figure 4–1. This connector is
supplied with an 8-position mating screw terminal plug. It provides two nonisolated sensor inputs SENSOR1 on pin 3 and SENSOR2 on pin 2, a sensor
return on pin 4 and +12V for sensor power SENSOR_PWR on pin 1. Each sensor
input can operate from TTL to 30V DC.
The JS connector also provides two non-isolated TTL strobe outputs STROBE1
on pin 6 and STROBE2 on pin 5, a strobe return on pin 7 and a CHASSIS GND
on pin 8.
The internal voltage reference signal VREF is connected to SENSOR_PWR on
the board, and is used to properly bias the sensor inputs.

Acuity 1000 Hardware Guide
Rev A, July 2001
Overview
For 12V sensors, supply power to your sensor using the sensor power
SENSOR_PWR on pin 1 on the sensor strobe connector JS.
For 24V sensors (30 volts maximum), you must provide an external +24V power
supply, which also sets the internal reference voltage VREF. Connect external
+24V to sensor power SENSOR_PWR pin 1 on connector JS and supply power
to your sensor using the sensor power SENSOR_PWR pin 1 on connector JS.
For TTL sensors, do not connect power to the sensor power SENSOR_PWR pin
1 on connector JS. You must remove jumper JMP1 on the Camera I/O Card. This
will properly bias the sensor inputs for TTL levels. See Figure 4–1, “Mini Opto
I/O Board,” on page 4-2.
WARNING! IF YOU CONNECT AN EXTERNAL POWER SUPPLY
THAT IS LESS THAN 12V TO THE SENSOR POWER PIN ON THE JS
CONNECTOR, YOU MUST REMOVE JUMPER JMP1 ON THE
CAMERA I/O CARD. FAILURE TO REMOVE THE JUMPER MAY
CAUSE DAMAGE TO THE MINI OPTO I/O BOARD AND THE
CAMERA I/O CARD.
Digital I/O
There are two dedicated input and four dedicated optically-isolated output points.
The field wiring is terminated on the two screw terminal connectors JI and JO.
There is a digital input connector JI, as shown in Figure 4–1. This connector is
supplied with a 4-position mating screw terminal plug. It provides two bidirectional opto inputs:
•
IN1 on pins 3 and 4.
•
IN2 on pins 1 and 2, corresponding to GPIO points 5 and 6 (see “General
Purpose I/O” on page 4-4).
Each input can operate with non-polarized DC signals from 5 to 50 volts with DC
currents from 0.5 to 5ma.

Note: Whenever the Sensor Power pin on JS is less than 12V, jumper JMP1 on the
Camera I/O Card MUST be removed.

Mini Opto I/O Board
There is a digital output connector JO, as shown in Figure 4–1. This connector is
supplied with an 8-position mating screw terminal plug. It provides four bidirectional opto outputs:
•
OUT1 on pins 7 and 8.
•
OUT2 on pins 5 and 6.
•
OUT3 on pins 3 and 4.
•
OUT4 on pins 1 and 2, corresponding to GPIO points 1 through 4 (see
“General Purpose I/O” on page 4-4).
Each output has a contact resistance of less than 20 ohms and can operate with
non-polarized AC or DC signals up to 50 volts at 100ma. Each output is protected
by a current limiting foldback circuit.
The I/O connector supplies the necessary +5 volts DC to operate the I/O board
via the I/O cable. There is no external power supply connector.
Note: Do not attempt to connect an external +5 volts DC power supply to the
Mini Opto I/O Board. There is no connector provided for this function. This
board receives its power via the I/O cable. Connecting an external power supply
will cause serious problems: the two power supplies will conflict with each other
to produce unpredictable results and the external power supply's ground may
cause ground loops to occur. Contact RVSI Acuity Customer Service at (800)
468-9503 for assistance.
In designing your vision application, you must decide which mix of input and
output ports you require.
To program your vision application, use AppFactory’s user interface software.
Refer to your Visionscape® Tools Reference Manual for more specific
information on how to assign the I/O.
General Purpose I/O
Visionscape® provides a complement of optically-isolated I/O communications
points called general purpose I/O (GPIO). You can configure the GPIO in the
Vision System Step properties page by setting the GPIO Input Mask property.
This mask defines which I/O points are programmed as inputs and which are
defined as outputs.
