2.4 EPD System-Initial Flow on Device Side
This section will explain how the end device joins, registers, and communicates with
the router. Users may change some parameters to fit their own scenario.
2.4.1 EPD Device Scan for Router
Initial scan: EPD device scans each available channel. If the EPD device still
can’t find the router after 2 mins, it will change the status to “lost connection”.
Reconfirm scan: The device will start to scan the channel to look for another
router every 2 mins. If a device still can’t find the router after 5 attempts, it will re-
scan the channel every 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 can’t find the router, 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.

–Router connects to DeviceOn/ePaper
EPD Device
–Default setting for shipping: Supports 11 channels.
–Power on auto check if a router exists and asks to join the network.
–Router permits EPD device to join if it is on the whitelist.
–EPD device joins the network
2.4.3 Status report
Router (WIS-3240) will report status every 1 mins.
EPD device will report status every 1 mins.
2.4.4 Execute actions Cmd
Router will receive action commands from the router 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.
2.5 Whitelist mechanism
Before importing the whitelist, the user needs to setup a router channel which can
provide optimal performance. Users can setup the channel from DeviceOn/ePaper
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 DeviceOn/ePaper.
(2).DeviceOn/ePaper can dispatch the list to the connected system daemon in the
Router.
(3) EPD device can auto join the network after the whitelist has been properly setup
in DeviceOn/ePaper and Router.
Note! End users need to be aware which 2.4Ghz wi-fi channels have been
used to avoid to using the same channels.

2.6 Secure Key Mechanism
Advantech EPD-230, EPD-232 asks users to change the secure key when data
exchanges between devices. Users can setup a new secure key from DeviceOn/
ePaper and the router 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 Router exchanges keys to devices automatically
