INTRODUCTION  
Congratulations on buying the Inca vision system!  
1.2  
SUPPLIED PARTS  
The supplied equipment comprises the following:  
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.  
One Inca 311 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.

HARDWARE  
The Inca hardware consists of the following modules:  
2.1  
TRIMEDIA PROCESSOR  
TriMedia processor  
CMOS sensor  
IEEE 1394 (FireWire™) 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 LED’s  
One system LED  
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 143 MHz or  
even 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  
8 MByte on-board flash memory  
32 MByte SDRAM  
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 allow 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.

TRIGGER / FLASH  
2.3.1  
IEEE 1394 (FireWire™)  
For the interconnection of the Inca camera to the host PC  
a so-called IEEE 1394 interface, also known as  
FireWire™, is used. For this link the PC must be equipped  
with an IEEE 1394 interface. This IEEE 1394 can be an  
onboard OHCI version, a PCILynx- or OHCI- IEEE 1394  
PCI expansion board in case of a desktop PC or a  
PCMCIA expansion card in case of a notebook. The  
number of Inca’s that can be connected to a single IEEE  
1394 interface depends on the number of ports available  
on the interface. The number of ports can be in the range  
one to six but is typically three. The integration of the  
physically IEEE 1394 interface into your Windows™  
operating system is achieved via a so called device driver.  
A device driver for the OHCI and the PCILynx version of  
the IEEE 1394 interface will be available for;

2.3.2  
Trigger and Flash  
The Inca has an optically isolated trigger input and flash  
output.  
Figure 2-2 Trigger/Flash connector  
The trigger input enables the feature to prepare the  
capture of an image. If programmed so 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

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.

OUTPUT  
2.3.4  
How to use the isolated input/output  
The optically isolated output is only a transistor. As can be  
seen in figure: 2-6 the emitter is connected via a 1M  
resistor to ground. It prevents the output transistor from left  
floating. If the output is conducting the output current Ion  
must be in the range 0.9 mA < Ion < 18 mA. The maximum  
Vce is 40 volt.  
In this part the user will find how the optical isolation is  
implemented in the Inca. Not only the digital input and  
output lines are optically isolated but also the flash and  
watchdog output and the trigger input.

INPUT  
Figure 2-6: Opto-isolated output Figure 2-5: Opto-isolated input  
As already mentioned in paragraph 2.3.3 Digital I/O the  
input current for Ion is between 6.3 mA and 10 mA. Ion is  
the current whereby the output transistor is conducting. In  
order to prevent the input from left floating, the return (n) is  
internally connected with a high impedance to ground. In  
order to let the input functioning properly the user must  
connect the common ground to the signal ground.  
Warning: Writing a True or One to the digital output results  
in an Ioff (out = high because of pull-up resistor), on the  
contrary writing a False or Zero to the Digital output results  
in a Ion (out = low because of transistor short circuit).

2.3.5  
Multi-purpose connector  
2.3.5.2  
RS232  
Looking at the back of the Inca the connector in the left  
bottom corner is a multi-purpose connector. The  
connector, a 9 pole micro-D connector, contains  
connections for an external power supply, 3-wire serial I/O,  
the input for an external system reset and a watchdog  
function.  
Pin 2 is the RS232 transmit data line.  
Pin 3 is the RS232 receive data line.  
The RS232 digital ground is connected to pin 7.  
Warning: When using the Micro D to Sub D cable (8122  
410 81530) which is also included in the starter kit please  
notice that the point 7 and 5 are interchanged all other  
points are interconnected one to one.

The watchdog connection is an opto-isolated output. Pin 4  
is the p connection and pin 5 is the n connection. This  
output can be switched under software control and can be  
made dependent of among others (software) timers. (p/n

2.3.5.1  
Power supply  
A single pole pushbutton connected between the pins 8  
and 9 can be used as an external system reset. (Available  
in the starterkit). For an internal reset the watchdog output  
can be connected directly to the reset input ( pin 4 - pin 8  
and pin 5 - pin 9) for this reason the reset input is not Opto  
isolated.  
The Inca is powered by connecting the external power pin  
1 to the + pole and pin 6 to the ground of a power supply.  
The voltage must be in the range 8..40 volts, but is  
typically 12..15 Volt. (The Inca starter kit; PCI 8122 410  
56851 or PCMCIA 8122 410 5651 contains a 15 volt 2  
Amp. power supply.)

compatible depending on the mode set via software. Both  
VGA and CVBS outputs support a non-destructive colour  
overlay. For connecting a VGA monitor a standard cable  
can be used. For the CVBS monitor connection no  
standard cable is available. A user made cable must be

POWERING UP  
2.4.1  
System LED  
When the Inca is powered up, the Inca will boot. One of the  
first things it will do is to start a self-test to make sure that it  
is functional. After correct completion of the test a check is  
added for the presence of a host that waits to download an  
application. If a host is connected the camera waits for the  
download of the application to be executed. The download  
is done via the IEEE1394 interface connection. When a  
download is in progress the Inca waits until the download  
is completed. After completion it starts the execution of the  
program.  
If the test for the host is negative then the Inca will load the  
program, if available, stored on the flash file system to the  
SDRAM and starts the execution. If no application is  
available the Inca starts capturing images and send the  
images to the VGA output. The latter will be the case if an  
Inca is powered-up for the very first time.  
The system LED is situated next to the IEEE1394  
connector. The system LED can illuminate in 3 colours  
namely red, green and orange. By connecting the power to  
the Inca the LED illuminates red. During start-up the LED  
is illuminating orange.  
Once start-up has finished the next step is the hardware  
initialization. During the start of this initializing phase the  
LED will blink for a very short time green and stays  
constant green when this phase is terminated successfully.  
If during this phase something goes wrong the led will blink  
in red constantly.  
During the time that a host can download an application  
the general purpose LEDs 1 and 2 blink orange alternately.  
After 3 seconds or a successful application download the  
Inca will (try to) start the default or downloaded  
application. If the system LED is blinking during this phase  
probably the file ‘RapIB311Lcm.rbf’ or the appropriate  
license file (Rhapsody.key or Clicks.key) don’t reside on  
the flash file system.  
For a more detailed meaning of the system led colors  
during the boot sequence please refer to the software  
manual.

SOFTWARE INSTALLATION  
There is no special software supplied with the Inca for  
installation purposes, so no installation is necessary. The  
start-up procedure and running an application is  
completely done by software control.  
A number of software products are available supporting the  
Inca and can be purchased from Industrial Vision.  
Available are:  
The ‘Rhapsody’ package, a powerful set of software  
tools for writing industrial vision applications. Rhapsody  
gives freedom of programming a specific user  
application with maximum performance and the least  
overhead.  
‘Clicks’ a graphical Inca user interface easy to be used  
by engineers.  
The Inca is also supported by ‘Promise’, a National  
Instruments LabVIEW add-on library, for developing  
industrial vision applications for measurement in sub-  
pixel accuracy. Using graphical representations for  
functions, selected and connected together, the  
application builder can create a program capable of  
executing a complex vision function.

MECHANICAL INTERFACE  
For the purpose of installation and handling the camera in  
an application two mechanical preparations have been  
made to the camera body:  
Three M4 screw holes in the bottom of the camera  
The one in the camera front end is the most important  
one because this comprises the sensor.  
The camera neck can be clipped onto a fixed ring  
(50mm h7)  
In both cases it is advisable to design a alignment pin into  
your mechanical placeholder

TROUBLE SHOOTING  
This chapter describes the action to take if the Inca board  
does not operate correctly. Moreover, the means of  
support are described.  
In case of a red blinking system LED (see 2.4.1 System  
LED) during the boot sequence but after the three seconds  
of blinking the general purpose LEDs 1 and 2 one of the  
following files are probably missing on the flash file system;  
‘RapIB311Lcm.rbf’ or the appropriate license file  
Rhapsody.key or Clicks.key. These files are required when  
you like to use the Inca either under Rhapsody or Clicks  
software control.  
5.1  
KNOWN PROBLEMS USING THE INCA  
When using the Micro D to Sub D cable (8122 410 81530)  
that is also included into the starter kit please notice that  
the point 5 and 7 are interchanged all other points are  
interconnected one to one.  
The Digital IO of the Inca does not have a defined reset  
status. Only after a complete boot of the Inca including the  
start of the user application the IO ports will have a defined  
level.  
The cleanness of the sensor is of major importance for the  
image quality. During the production of the Inca special  
account is taken with respect to the cleanness of the  
sensor. However when you remove the sensor protection  
cap from the Inca front end prior to the mounting of the  
lens, the sensor can attract some dust or dirt. This pollution  
can affect the image captured with the Inca. Remove the  
sensor protection cap only in a clean environment by  
holding the Inca with the sensor facing down. After  
removing the sensor protection cap inspect the cleanness  
of the sensor and immediate assemble the required lens to  
the Inca.

SERVICE AND SUPPORT  
Service  
5.2.3  
Support Channels  
5.2.1  
Support can be received through the following channels:  
E-Mail:  
Internet:  
The Inca has built-in identification codes for hard and  
software in order to facilitate service and support. These  
codes are displayed during the boot time. If a problem  
occurs these codes can help to determine quickly the level  
of equipment being used. The programmable hardware  
can be altered or updated by downloading a file. There is  
no need for changing components.  
5.2.2  
Software Support Agreement  
Although no software is delivered with the Inca, apart from  
buying an Inca software can be purchased from Industrial  
Vision. At the same time a Software Support Agreement  
can be purchased. A Software Support Agreement offers  
several benefits, which are not available to other users.  
The most important are:  
free telephone support  
free fax support  
free release updates  
Although free telephone and fax support are also available  
to other users, users with a Software Support Agreement  
will be given a higher priority when support questions are  
raised. Holders of the agreement will also automatically  
receive new releases of the software.
