CHAPTER THREE - PL3000 BASICS

NID Power Button
Through a NID Power Button applet you can customize the functioning of the
power button. The power button has two attributes to be changed:
• ‘Virtual key’ – whether or not the Power button press generates a
virtual key code; the virtual key code can be chosen freely
• ‘Hold time’ – how long the power button shall be held down until the
system powers down itself.
NID Scanner
A NID Scanner applet gives you control of the scan engine of the optical tag
reader and of the scan operation itself on the PL3000 as follows:
• Enabling/disabling barcode decoding on a barcode-to-barcode basis
• Setting the barcode’s optional parameters
• Setting the triggering mode of the scan key
• Setting the timeout for the barcode reading
• Adding affixes and placeholders to the read code string
• Replacing the mark in the read code string with another
• Setting how success and failure of the barcode reading is indicated to
the user
• Testing the barcode reading to see if the reader reads a particular
barcode
Be aware that the NID Scanner applet is not so much a control panel applet as
a sample utility to demonstrate the configuration options being available on the
scan engine on your PL3000.
NID SNTP Service
If your business application requires keeping the PL3000(s) in synch with your
servers’ time, a NID SNTP Service applet makes a Simple Network Time Protocol
(SNTP) client available on your Nordic ID PL3000. The SNTP client can retrieve
time value from one source. In addition to the address of a time server, you can
specify a destination port on which the service is available.
Furthermore, the implementation of the SNTP client demands polling
parameters. With a ‘Settings’ page of the applet you can also adjust the following
parameters:
• ‘Update interval’ - how frequently the client checks time (either in
minutes or in hours)
• ‘Timeout’ - how long to wait for the response from the server before
resending the time check request
• ‘Retries’ - how may times to retry before giving up per the update
interval.
This applet also provides a facility for adjusting manually the system time of
the device. You can link a time query user dialog utility, called ‘AskTime’, to the
SNTP queries. There are two property pages to customize (to localize) the text
fields of the user interface of the AskTime in this applet.
