B-2 TCP/IP and Resource Tests for ZonicBook/618E 987295 Appendix B
What does the TCP/IP test tell me?
The TCP/IP test provides test results for “Pinging Device” and “TCP Connection Test.”
Pinging Device. The Pinging Device test is an ICMP (Internet Control Message Protocol) ping test. In
addition to indicating either “Passed” or “Failed,” the test displays;
(a) The round-trip time of the ping, for example, <10 ms.
(b) 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.
TCP (Transmission Control Protocol) Connection Test. The result of the TCP 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.
How to run the Resource Tests
For Ethernet devices, such as ZonicBook/618E, you can run the Resource Test after a successful
completion of the TCP/IP test with a simple click of the <Resource Test> button.
What does the Resource Test tell me?
The Resource Test includes two categories of test, Resource Tests and Performance Tests.
Resource Tests. The resource tests are intended to test system capability for the current device
configuration. Resource tests are pass/fail. Test failure may indicate a lack of availability of the resource,
or a possible resource conflict.
Base Address Test. This resource test checks the base address for the selected port. Failure of this test may
indicate that the port is not properly configured within the system. See relevant operating system and
computer manufacturer’s documentation to correct the problem.
Interrupt Level Test – Tests the ability of a parallel port to generate interrupts. Failure of this test may
indicate that the parallel port may be currently unable to generate the necessary hardware interrupt, while
other parallel port devices may work OK in this mode. Some parallel port devices (such as printers) do not
require interrupts to work properly. See relevant operating system and computer manufacturer’s
documentation to correct the problem.
Performance Tests. These types of tests are intended to check various device functions, using the
current device configuration. Performance tests provide quantitative results for each supported functional
group.
Test results represent maximum rates the various operations can be performed. The rates depend on the
selected parallel port protocol, and 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 through the parallel port.
Results are given in samples/second, where a sample (2 bytes in length) represents a single A/D value.
