Using NodeUtil

• Number of iterations – How many times to repeat the performance test

before displaying the collected data. The default is once. For an

indefinite number of iterations, specify 0. You can press the [ key at any

time to end the test.

• Delay between messages – How long, in milliseconds, to delay between

sending messages to the device. The default is no delay.

• Acknowledged, Unacknowledged, Request, or Repeated – The type of

message service to use for each message. The default is Acknowledged.

• Retry count – How many times to retry sending a message before

marking it failed. The default for FT channels is three times; the default

for power line channels is seven times.

• Use authentication – Whether (Yes) or not (No) to use authentication for

the messages. The default is No.

• Message code – The message code to send to the device. The default is

0x0000.

• Up to 100 bytes of hex data – The data that you want to send to the

device.

The result of the test is displayed at the conclusion of the test. For example, if
the tests were successful, you receive RESULT: No failures. For an
unsuccessful test, you receive a summary of the failures, such as RESULT: 2 of
50 messages failed ( 4.00%)

.

You can also use the Report device (S)tatus and statistics command to see how

the test affected the statistics collected by the device.

= – Signal Strength

Use this command to perform a series of tests of the signal strength for a device

attached to a power line channel. The tests include both the Primary (normal)

and Secondary (alternate) LonTalk paths. The displayed output includes a
summary of packet errors, margin, and signal strength.
This command is not valid for devices that are not attached to a power line

channel.

* – Refresh Memory

Use this command to perform a series of Refresh Memory network management

commands on the device. Use this command to refresh the local non-volatile

memory (on-chip EEPROM or external EEPROM or flash memory).

<

– Redirect Input from a File

Use this command to run a command script. A command script is a text file that
contains NodeUtil commands. A script file can use have any file extension, but a

common extension is “.scr”.

Commands that do not require a carriage return must be on their own line.

Input that requires a carriage return must be on its own line. Network variable

data is displayed (and entered) in hexadecimal.
