78 EX10xxA Web Page Operation
It should be noted that the use of this button does not eliminate the need to click the Apply button
to accept the changes.
Initialize
Clicking on this link will begin an acquisition, transitioning the trigger model from the IDLE layer
to the ARM layer. This command clears the FIFO reading memory and resets all limit indications.
Abort
Clicking on this link will abort the current acquisition and returns the trigger model to the IDLE
layer. Once an acquisition has begun, most commands are not accessible. The abort command is
used to prematurely end the acquisition in order to make configuration changes. Acquired data is
not affected by the issuance of an abort.
Software Arm
Clicking on this link will perform a software arm of the trigger model. Software arms are always
enabled as an ARM source and can be used to perform a bypass of the configured ARM source. The
software arm applies at the time it is issued and will be ignored if the system is not waiting for an
ARM event. The issuance of a software arm has no effect on the ARM source configuration.
Software Trigger
Clicking on this link will perform a software trigger of the trigger model. Software triggers are
always enabled as a TRIG source and can be used to perform a bypass of the configured TRIG
source. The software trigger applies at the time it is issued and will be ignored if the system is not
waiting for a TRIG event. The issuance of a software trigger has no effect on the TRIG source
configuration.

LAN events are used for device communication over Ethernet. The LAN events menu is used to
configure the EX10xxA’s LAN event arm and trigger lines.
Configuration
This entry page is used to define how the EX10xxA responds to LAN events. Each LAN event
trigger line can be set to arm or trigger on a packet with the same event ID as specified in the
Event
ID field (default values shown below). Note that each line can arm or trigger on different LAN
events (i.e. LAN event line LAN0 could arm on Event ID LAN1, but trigger on Event ID LAN3).
Additionally, the user can use the
Filter field to specify which network hosts are allowed to trigger
the LAN event line. The format of this field should be “hostname:port”. When the hostname is set
to blank or “” (default), the EX10xxA will accept all UDP and TCP packets on port 5044. If set to
“ALL”, the instrument will allow multicast UDP packets.
From this page, the user can also set the instrument’s LAN Domain and configure the LAN event
log. By clicking on the
Log Enable checkbox, the EX10xxA will record LAN events as they occur.
The Log Overflow Mode radio buttons affect how the log buffer will operate once it becomes full.
If Overwrite Old is selected, the existing log will be overwritten by new LAN events, while
selecting Ignore New will ignore all LAN events that occur after the buffer is full.
