The Pinging Device test is an ICMP (Internet Control Message Protocol) ping test.  

In addition to indicating either “Passed” or “Failed,” the test displays the round-trip 

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. 

 

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.
