2.4 EPD System-Initial Flow on Device Side
This section will explain how the end device joins, registers, and communicates with
the gateway and router. Users may change some parameters to fit their own scenario.
2.4.1 DEvice Scan for Router
Initial scan: EPD device scans each available channel. If the EPD device still
find the router after 2 mins, it will change the status to
Reconfirm scan: The device will start to scan the channel to look for another
router every 2 mins. If a device still find the router after 4 attempts, it will rescan the channel every 2, 4, 8, 16, 32 mins, then every 64 mins for 5 days.
Finally the device will move to deep sleep mode after scanning for 5 days continuously.
Stop scanning and deep sleep: If the EPD device still find the router
finally, it will stop RF Scanning and go back to deep sleep mode until the button
of the device has been pressed. The device will start scanning from the beginning.

EPD device will report status every 1 mins
2.4.4 Execute actions Cmd
Router will receive action commands from the gateway in real-time .
EPD device sends data requests every 20 secs from sleep mode to router to
check if there are any action commands.
EPD device will send back the ACK turn result if the action command is exe-
cuted.
2.4.5 Firmware update
WISE-1840 network control card in the Router will receive FW upgrade com-
mands from the router in real-time and execute automatically. System will
reboot after FW upgrade is complete.
EPD device sends data requests every 20 secs from sleep mode to the router to
check if there is any action command. EPD device receives FW upgrade com-
mands if there is FW upgrade action. After upgrading, the EPD device will re-
register network.
2.5 Whitelist mechanism
Before importing the whitelist, the user need to setup a router channel which can provide optimal performance. Users can setup the channel from ePaper manager and
the router channels are: 11 13 14 15 20 21 22 23 24 25 26. If the channel has not
been set, the router will be set to the default channel of 15.
(1). When a user receives the goods, it comes with an EPD device whitelist. Users
need to import the list from ePaper manager.
(2).ePaper manager can dispatch the list to the connected system daemon in the
Gateway.
(3) EPD device can auto join the network after the whitelist has been properly setup
in ePaper manager and Gateway.
Note! End users need to be aware which 2.4Ghz wi-fi channels have been
used to avoid to using the same channels.
9 EPD-023 User Manual
2.6 Secure Key Mechanism
Advantech EPD-023 asks users to change the secure key when data exchanges
between devices. Users can setup a new secure key from ePaper manager and the
gateway will start passing the new key to connected devices. As long as the key has
been changed, the device can not operate in the original system which has a different
secure key setting.
Data communication is encrypted by AES128
Users can define a 128 bit secure key
The Gateway exchanges keys to devices automatically
