1 INTRODUCTION

Congratulations on buying the Inca vision system!

An Inca is a high quality intelligent camera for image

acquisition and processing. Inca offers a complete vision

system that is ACCURATE, FAST, COMPACT and COST-

EFFECTIVE. The high-resolution, high dynamic range

sensor provides the best basis for the development of a

very accurate vision system. Having all the processing

power close to the sensor and the capability of region of

interest processing reduces processing time and thus

faster systems can be realised. Because of this integrated

processor, display capabilities and industrial I/O, the Inca

offers a very compact total vision solution, without any

need for additional hardware like e.g. a PC. This makes an

Inca solution besides very cost-effective also transparent

and easy to work with. Finally the industrial housing

provides optimal possibilities for incorporating the Inca in

almost every (industrial) environment.

1.1 ABOUT THIS MANUAL

This manual explains how to install your Inca camera and

how to check that it is working correctly.

1.2 SUPPLIED PARTS

The supplied equipment comprises the following:

• One Inca 320 camera.

• One hardware manual (this document).

If any of these items is not included notify your supplier

immediately.

1.3 ABOUT THE INSTALLATION

The installation consists only of making the right

connections to the Inca. Start-up and running an

application is completely done under software control.

Software is not provided with the Inca, but is a separate

product that can be purchased from Industrial Vision. Refer

to chapter 3 for available software.

2 HARDWARE

The Inca hardware consists of the following modules:

• TriMedia processor

• CMOS sensor

• Ethernet 10BaseT/100BaseT interface

• RS232 serial interface

• Video outputs VGA and CVBS

• Digital inputs and outputs

• Trigger input and flashlight output

• Reset input and watchdog output

• Four general purpose LEDs

• One system LED

• 8 MByte on-board flash memory

• 32 MByte SDRAM

2.1 TRIMEDIA PROCESSOR

The core of the Inca is the TriMedia 1300 processor. This

Very Long Instruction Word CPU (max. 5 parallel

instructions) with image co-processor runs on 180 MHz.

Among others, this processor handles:

Image and control data flows

Storage of acquired images. The images are stored in the

32 MByte on-board SDRAM.

Processing of the image stored in on-board SDRAM

Interaction with its environment for product information and

measurement results

Programming this TriMedia processor can be done using

the Rhapsody C/C++ software package or a graphical

development environment called Clicks. The TriMedia part

of this software is based on the real time operating system

pSos™. Especially for high-end vision applications this is

very important, because in this way the timing of the

application is deterministic, this in contrast to programs

running in Windows™.

Clicks allows application engineers to graphically compose

the tasks to perform. Without the need of programming

expertise this tool is easily accessible for most engineers

and offers a very natural and interactive way to realize your

application.

2.2 CMOS SENSOR

2.2.1 Inca 320

In the Inca 320 a monochrome sensor IBIS5A-1300 from

FillFactory is implemented. This sensor is dedicated to

industrial machine vision solutions and has both a rolling

and a synchronous shutter. High dynamical range scenes

can be captured using the double or multiples slope

functionality. The following main features, supported by the

Inca 320, are available:

• 1280 x 1024 Pixels

• 10 bit 40 Msample ADC resolution

• 2/3” sensor housing

• One region of interest

• Programmable exposure time

• 10, 20 or 40 MHz pixelclock

• Full framerate 27 frames per second

• Optical dynamic range 64 dB in single slope,

up to 100 dB in multi slope.

• Synthetic test image

• Decimation factor 2 for higher frame rates of sub-

sampled images

2.3 CAMERA CONNECTIONS

The rear side of the camera gives the user a great number

of possibilities for interfacing the camera.

• 10BaseT/100BaseT Ethernet

• One trigger input and one output for flash control

• Digital input 6 bits optically isolated

• Digital output 6 bits optically isolated

• RS232

• Camera reset

• Watchdog

• VGA and CVBS for display purposes

2.3.1 10BaseT/100BaseT

For the interconnection of the Inca camera to the host PC

a so-called 10BaseT (for 10Mbs) or 100BaseT (for

100Mbs) connection is used, which is a twisted pair

connection for Ethernet. For this link the PC must be

equipped with an Ethernet Controller.

In order to be able to control multiple Inca 320 cameras a

decent knowledge of how an Ethernet network has to be

configured is required. This manual assumes the reader

has this knowledge.

Figure 2-2 Inca 320 Ethernet Connector

The Ethernet connector has two LEDs. LED A is the

activity LED and will blink when there is activity. LED B will

be lit when the connection is using 100MBs.

To connect a single Inca camera directly to a PC, a

crossed twisted pair cable is required.

2.3.2 Trigger and Flash

The Inca has an optically isolated trigger input and flash

output.

The trigger input enables the feature to prepare the

capture of an image. If the trigger is enabled by an

application program the capture process will start

immediate when the trigger input is signaled. A rising or a

falling edge on the input can indicate the trigger.

The flash output can control the external flash unit if

required. The active state (high or low) can be

programmed, see the note for side effect.

Note: The start-up sequence for the Inca has

consequences for the flash output. In case the flash output

is configured as a non-inverting output the output is zero

and stays zero and awaits control by the software.

If the output is configured as an inverting output than

during the start-up sequence the output equals the value of

the power supply. This situation stays that way until the

software has taken over the control. In case a flash unit is

switched to the on position with a positive input, the flash

unit will flash or lit continuously.

2.3.2.1 Using the Trigger Input

The trigger input is optically isolated that is different from

the digital I/O as described in 2.3.3.

The following diagram shows an example of how to use

the optical Isolated input.

24V

2K7

Figure 2-4 Optical isolated trigger input

When the diode is conducting and thus emitting light, the

software will interpret this as a binary ‘1’.

The input is TTL level compatible.

• input current 6.3 mA < Ion < 10 mA

• Pmax 20 mW

2.3.2.2 Using the Flash and Watchdog

Outputs

The flash and watchdog outputs are optically isolated that

are different from the digital I/O as described in 2.3.3.

The following diagram shows an example of how to use

the optical output.

24V

Figure 2-5: Optical isolated flash and watchdog outputs

When the flash output is defined as active high and the

software sets the flash as active, then the state of the

output is Ioff, and the transistor will not be conducting.

When the flash output is defined as active low, and the

software sets the flash as active, then the state of the

output is Ion, and the transistor will be conducting.

The watchdog will behave the same as the flash output in

the active high definition. More information about the

watchdog can be found in 2.3.4.3.

2005-12-12 Page 7

The inputs and outputs are not protected in any way, so

care must be taken when connecting anything to these

inputs and/or outputs.

All inputs and outputs are TTL level compatible.

• output current 0.9 mA < Ion < 18 mA, Vce max 40 volt

• Pmax 20 mW

2.3.3 Digital I/O

The Digital Input and Output connectors give the user

the possibility to connect and control a number of devices.

For that purpose 6 output and 6 input lines are available.

These output and input lines are optically isolated from the

Inca.

Input 6 differs from the other inputs in a way that it has a

special purpose. Input 6 can also be used as an interrupt

input that is either level or edge sensitive.
