Toss parameter
CAUTION
:. If the connection goes down, the Toss parameter throws away old data after the
specified Toss time (2 to 99 minutes), until the connection is re -established. Consideration
should be taken to adjust the toss time according to the sample rate so that the toss delay
time expires before the RAM fills causing acquisition to stop.

The following is an example with a verbose response:

Check the IP Address, Mask, Host, and Gateway Addresses.
Example NET configurations with Ethernet link down and acquisition on:
1.
If the unit parameters are set to dump to disk ONLY then there is no effect.
2.
If the unit parameters are set to dump to Ethernet and to disk, then the unit will dump the data to
disk when the RAM reaches the dump point (default = 66% full), but the RAM will not empty until the
data is sent out over the Ethernet link or the unit switches to toss mode and discards the data
destined for the NET Port.
3.
If the data is being sent only to Ethernet, then the RAM will fill until the toss delay threshold is
reached. Once the Ethernet connection is re-established, the data in RAM will be sent out the
Ethernet port and acquisition will re-start automatically.
CAUTION
:. There will be only a loss of data while the acquisition state is off.
