HALCON 7.1 Frame Grabber Interface for Pleora iPORT IP Engine
This page provides the documentation of the HALCON iPORT interface. Using this interface you can use any camera that is connected through the iPORT IP Engine from Pleora. Note that the software installation from Pleora typically also contains a HALCON interface using a different name, see remark below. Registered customers can download the latest revision of this interface from the MVTec WWW server.
Revision: 2.3
System Requirements
- Intel compatible PC with Windows 2000/XP.
- Best performance is reached with a network card from the INTEL Pro 1000 family (82540, 82541, 82546 chip). Then you can use the high performance driver Pro1000.sys (version 2.2.0). With other network cards you reach less performance and have a higher CPU usage.
- Successfully installed Coyote software (version 2.2.0).
- HALCON frame grabber interface HFGiPORT.dll or
parHFGiPORT.dll, respectively.
If you have properly installed the interface, both DLLs should reside in bin\i586-nt4 within the HALCON base directory %HALCONROOT% you have chosen during the installation of HALCON. - With the Coyote application you have to create a file named Config.xml, which must reside in the current working directory.
- The camera must have a valid IP address before accessing it with HALCON. The recommended way is to use an DHCP/BOOTP server.
Features
- Synchronous and asynchronous grabbing.
- External camera triggering.
- Support for a wide range of Camera Link and GigE cameras.
- Software control of various camera features.
- Software control of additional parameters depending on your specific camera.
Limitations
- No LUTs.
- grab_region and grab_region_async not supported.
- No support of driver version 2.3, i.e., no support of standard GigE Vision cameras.
- No support of intern color conversion.
Remarks
There exist several acquisition devices, which are supported by this
interface, e.g., from DALSA, Imperx, JAI, and Mikrotron.
The underlying driver is based on the IPORT IP Engine from Pleora.
Some cameras have additional parameters, which are described in their
documentation. It is possible, that in such a case not all parameters
(but the majority) described below are actually supported.

| 'pulse_gen_count' | count (int) | Returns the number of pulse generators available. | |||
| 'pulse_gen_get' | pulse_gen (int) | The values of the pulse generator. Note that the index of the pulse generator has to be set before calling this function. | |||
