7.5.2 Capturing snapshots (snapshot mode)
Proceed as follows if you want to use the analyzer device NANL-B500G-RE
in the autonomous operating mode
in Snapshot mode with an USB memory
device and only want to capture data from certain time windows via defined
triggers:
Step 1: Safety precautions
Device Destruction
Ø
The voltage applied at the NANL-B500G-RE device must not exceed 30
V, otherwise the device may be destroyed.
Ø At the I/O signal pins of the external IO interface use exclusively 3.3 V
or 24 V signaling voltage! Higher signaling voltages lead to severe
damage to the NANL-B500G-RE device!
Step 2: Connect the device to USB, use the autonomous operating
mode
in the snapshot mode and transfer evaluation data to a PC
Ø
Connect the analyzer device NANL-B500G-RE to an external 24V
power supply .
Ø
Create a netANALYZER Scope project and configure the trigger criteria
for the Autonomous mode.
Ø Save the netANALYZER Scope project as a .prj file.
Ø
Copy the .nsprj file to the root directory of an USB memory device.
Ø
Connect the USB memory device (with sufficient free memory capacity
to store snapshots, see section
Autonomous operating mode, general
conditions and requirements [ } page 39]) to the USB socket on the
reverse side of the analyzer device NANL-B500G-RE.
Ø
When using an USB device with a power consumption of more than 500
mA, connect a separate power supply. If required, it is also possible to
feed it via an USB hub.
Ê
The analyzer device NANL-B500G-RE displays the autonomous
operating mode (snapshot mode) as a particular LED state (STA0-LED/
orange/flashing cyclic at 1 Hz, refer to section
SYS, STA0, STA1, I/O,
LINK and RX (Front side) [
}
page 75]).
Ø To start capturing, briefly press the red REC button on the front side of
the device, provided that in the project configuration, in the settings for
the Autonomous operating mode, the autostart behavior is set to
"Manual".
Ê If the behavior is configured to "Autostart", the capturing process will
start immediately without pressing the REC button. This is especially
useful if the analyzer device NANL-B500G-RE is to be switched
automatically to the capturing mode after a power failure.
Note:
If when switching on the analyzer device NANL-B500G-RE a USB
memory device with a partition marked as "bootable" is connected
to the analyzer device NANL-B500G-RE, the netANALYZER device
may not start correctly (SYS LED is yellow).
