NID SNTP Service
If your business application requires that the RF650M mobile reader is synchronized with the
time of day of your server, you can use the "NID SNTP Service" applet to make an SNTP
client (Simple Network Time Protocol) available on the mobile reader. The SNTP client can
obtain a time value from a source. Apart from the address of a time server, you can specify a
destination port on which the service is available when necessary.
To implement the SNTP client, polling parameters are also necessary. On the "Settings" tab
of the applet, you can adapt the following parameters:
●
Update Interval
Specifies how often the client checks the time (in minutes or hours).
●
Timeout
Specifies how long the client waits for a server response before sending the time check
request again.
●
Retries
Specifies how often the attempt is repeated per update interval.
This applet also provides the option of adjusting the system time of the device. For time
queries, you can link the user dialog utility "AskTime" to the SNTP queries. To customize
(localize) text boxes of the user interface of AskTime, there are two tabs in the applet.
Apart from using AskTime, you are also instructed to start the SNTP client in the "Settings"
tab.
NOTICE
Saving the system time
The mobile reader is equipped with a real-time clock chip. This is supplied by the
rechargeable backup battery so that the system time is not lost during a restart.
NID Touchscreen
With this applet you can activate/deactivate the touchscreen.
PC Connection
With this applet you can enable or disable the PC connection that is based on the Microsoft
ActiveSync technology. The ActiveSync connection via USB is the standard medium on the
RF650M mobile reader.
The ActiveSync connection is only possible if you have installed Microsoft ActiveSync and
the USB driver for the ActiveSync connection provided by Siemens on your Windows PC.
The PC connection established via USB should then run in plug and play mode. Remember
that you cannot connect the USB cable directly to the device. Instead, connect the USB
cable to the charging station of the mobile reader (you will find more information on the
charging station and USB connection in the operating instructions of the charging station).
