Basler pylon .NET API / pylon Viewer / Camera auto disconnects when starting Continous Shot

luis-fernando-rigoni report abuse

Hi,

I'm getting this error when I start Continuous Shot in pylon Viewer:

Exception caught while executing acquisition stop, msg='Control channel not open. : LogicalErrorException thrown (file 'gxport.cpp', line 110)'

I'm testing this with 2 computers, a Windows 10 x64 PC (development machine) and a Windows 10 x64 Tablet (rugged, production system), and the error happens ONLY in the tablet.

The camera and the PC are connected with cable at a switch, and tablet via Wi-Fi.

SDK version: 6.1.1.19832 Camera model: acA1300-60gc

Using script StartPylonViewerWithLogging.cmd from SDK, I've got this pylonLog.txt excerpt:

HI Luis,


You have isolated the problem in proper way. The problem is the network communication via WLAN is not stable enough.

If you want to operate a Basler camera in a WLAN, you may have to change the network-related parameters of the camera.

This is because the bandwidth available in a WLAN may be limited. The default camera settings may not be sufficient to establish a stable network connection.

To configure the camera to operate in a WLAN:

Install the pylon Camera Software Suite (Windows or Linux).
Make sure the camera is installed and configured as described in the Hardware Installation (GigE Cameras) topic.
Connect your computer to the WLAN.
Open the pylon Viewer.
Set the GevSCPSPacketSize parameter (i.e., the packet size) to 1500.
Tip: Use the search feature in the pylon Viewer to quickly find a parameter setting.
Set the PixelFormat parameter (i.e., the pixel format) to an 8-bit pixel format, e.g., Mono 8.
Set the GevSCPD parameter (i.e., the inter-packet delay) to a high value.
This decreases the current device throughput (GevSCDCT parameter).
The minimum inter-packet delay and the maximum current device throughput depend on the quality of the WLAN connection. A higher connection quality will allow a lower inter-packet delay.
Start continuous image acquisition.
If the resulting WLAN connection is unstable, return to step 7 and increase the inter-packet delay further.
