NTP service
A NTP service (Network Time Protocol) can be used to synchronize the time on devices across a
network. A NTP time server is used to obtain the correct time from a time source and adjust the
local time in each connecting device.
INRIM provides a synchronization service for informatics system connected to the Internet, based
on two primary NTP (Network Time Protocol) servers installed at the Time and Frequency
Laboratory.
The INRIM NTP servers can be reached by means of the following addresses:
ntp1.inrim.it (193.204.114.232)
ntp2.inrim.it (193.204.114.233)
IMPORTANT: save the settings with the button Save NTP Setup.

RS485 settings
Device ID :
Address NP2/NP5 in the 485 bus. This address MUST be univocal, two
devices with the same address can not co-exist on the same bus.
Response delay:
Minimum delay between end of reception of the pack and delivery of the reply.
NP2/NP5 can be connected to an RS485 communication bus through a serial port, which is
controlled from a master system or by a computer.
Due to interference from outside the serial line, one may find anomalous behaviour from part of
the master system which could cause possible damage to NP2/NP5. To avoid this mishap one
must take the following precautions:
1. Do not let the serial cables transit in the same conduits as power cables or cables with
elevated voltage. Maintain a safety distance of at least 10 cm. between these cables.
2. Connect serial cable screen to the ground the on one of the two sides (do not connect the
screen from both sides); in addition, the ground connection of the screen must not be made in
the same point in which piloted circuits of elevated tension are connected.
3. Cut the voltage of the entire system before beginning the wiring of the serial lines: even
dispersed or parasite currents could damage the modules.
IMPORTANT:
The internal electronics of NP2/NP5 are not galvanically insulated from the RS485 line; in
case of short circuit or discharge to ground, it is possible to damage not only the NP2/NP5, but
even the master system to which it is connected!
For the RS485 connection, one must remember to ignore the transmission echo from the
master that is returning through the serial line.

How to update the Bootloader (BL) or Application (App) Firmware?
If you have an NP2/NP5 device with the BL firmware version equal or less to the version "A.3",
and the App with version equal or less to the version "3.0.2", it is necessary to follow the below
instructions.
To update the newest firmware versions is it possible to use this web page for both: Bootloader
and Application.
The process uploads the file in the SD card memory, inside the directory "updates", check the file
integrity using the CRC info and then decrypt the data and write them in the Flash area.
Instead, in the App, after the integrity check will recall a sw reset, in order to execute the
bootloader that will find the file in the "updates" directory.
For both process, at the end, in case of success, the update file will be deleted.
IMPORTANT:
To update firmware wait 4 minutes, after it is recommended to switch off and on
NP2/NP5 device.
USB Firmware Update ( optional )
1. Update the App firmware using the well know USB method, saving in the USB Flash root the file
"dASys_F4_v3.x.xx.bin".
2. Plug the USB Flash memory to the NP2/NP5 device.
3. Power on the NP2/NP5 device and wait 4 minute.

Standard Player configuration
NP2/NP5 works just like a standard player in this mode and does not require any specific
programming or playlist file. The tracks will be played in the sequence in which they are
memorised in the flash memory; if a block of data is transferred then the written sequence in the
flash memory will depend on the operating system used.
