4. Test the system connections.
a. Make sure the device has been properly installed and is powered-on.
b. Make sure all cables are properly and securely connected.
c. Click the “ Test Hardware ” tab.
d. Click the < TCP/IP Test > button. This tests the Transmission Control Protocol / Internet
Protocol. The TCP/IP test has two components: Pinging Device and TCP Connection .
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.
When testing a DaqBook/2000 or a DaqOEM/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 DaqBook/2020, DaqBook/2001, DaqBook/2005,
DaqOEM/2001, or DaqOEM/2005 to the Ethernet.
