Ethernet grabber
Firmware 1.3.0 introduces the possibility to transmit acquired images using TCP/IP connection. When
the camera is connected using a gigabit ethernet network, up to 25 frames per seconds can be sent in
full server resolution (640x512).
The ethernet grabber is controlled using
exec ethernetgrabber start
and
exec
ethernetgrabber stop
commands.
Once enabled, the camera waits for incoming TCP connection on port 8889. The streaming of the images
starts immediately once the TCP connection established.
Note: The ethernet grabber must be restarted after each camera reboot.
Date/Time management
During the camera boot sequence, the camera tries to connect to the server ntp.unice.fr to get the
current date/time.
If the server is not accessible for any reason, the date/time of the camera is invalid.
The camera does not require that a valid date has been set to operate properly. However, firmware
1.3.0 allows to get and set the date using
“date”
and
“set date”
commands.
Note: Having a proper date set may be useful when contacting the support, since it allows to correlate
events stored in the camera internal logs with the current date.
Note: Due to lack of battery backed RTC, the date must be set after each reboot.
Image pattern
The firmware 1.3.0 introduces the possibility for the camera to send a pattern instead of actual sensor
image.
This specific mode can be used to diagnose connectivity issues (damage camera link cables, …. )
The camera can be configured to send a ramp or a fixed value for all images
When the camera is configured to send a ramp, first pixel sent by the camera is 0, the second pixel 1,
and so on. When the maximum value (16383), is reached the pixels is set to 0 again.
The ramp pattern is selected using the command
“set imagepattern ramp”
.
When the camera is configured to send a fixed values, all pixels are set to the specified value.
The fixed pattern is selected using the command “
set imagepatttern constant <value>
”
To revert to standard camera operation, use the command
“set imagepattern off”
.
