time of the ping, for example, <10 ms; and Packet Loss expressed as a percent of
data lost.
A long ping round trip time, for example, >50 ms and/or any packet loss indicates
a slow network that is not optimized.
If the Pinging Device Test fails a <Details> button will appear just above the
<Resource Test> button. If this is the case, click the <Details> button to
obtain possible causes and possible solutions.
The result of the TCP (Transmission Control Protocol) test will be either
passed or failed. If the TCP test failed a <Details> button will appear just above
the <Resource Test> button. If this is the case, click the <Details> button to
obtain possible causes and possible solutions.
e. Upon completion of the TCP/IP test, click the <Resource Test> button. The
Resource Test consists of two components: Resource Tests and Performance
Tests.
The Resource Test performs a quick communications check. If the host PC can
communicate with the device a message that the test passed is displayed.
The Performance Tests obtain quantitative results using the current
configuration of the acquisition device. The test results represent the maximum
rates at which various operations can be performed, and will vary according to
port hardware capabilities.
The ADC FIFO Input Speed part of the test results in a display of the maximum
rate at which data can be transferred from the tested device’s internal ADC FIFO
to computer memory. Results are given in samples/second, where a sample
(2 bytes in length) represents a single A/D value.
When testing a DaqLab/2000 Series or a DaqScan/2000 Series device, if
the unit does not respond within 30 seconds perform the following steps:
1) reboot the system
2) upon power-up, re-open the Daq Configuration applet
3) select another configuration setting
4) reinitiate the test
This completes the procedure for connecting a DaqLab/2000 Series or a DaqScan/2000 Series
device to the Ethernet.
