Abstract
This manual provides specifications for the EE-420R Electronic Shelf Label (hereafter referred to as
Overview
The EE-420R is an Electronic Shelf Label with a 2.4GHz radio for data communication. The product
has a 3-color E-ink based e-paper display with black, white and red pixels. This product uses Direct
Sequence Spread Spectrum RF technology that allows for an ultra-low power consumption combined
with a reduced sensitivity to background noise. That means less interference by other radios that
operate in the 2.4GHz band. The radio protocol that is used is based on the IEEE 802.15.4 standard
that specifies the physical layer and media access control for low-rate wireless personal area
networks. The protocol is entirely implemented, except for some small changes that have all to do with
the connection protocol to a base station. When the base station is not available the EE-420R
switches to a non-802.15.4 standard to lower the power. That is especially meaningful when the EE-
420R is not being used for a prolonged period of time (e.g. during shipping)
The EE-420R is intended to be operated in combination with a base station such as the EBS-40 which
can control a large number of EE-420R and other types of ESL of the same family such as EE-202
and EE-750.

See below
The ESL is in sleep mode almost the entire time. The device wakes up at regular intervals (called the poll
time) and it then transmits a poll request to the base station. When the base station has no data to send, it
just acknowledges the poll after which the ESL immediately goes back to sleep. The poll rate is
configurable and is set to 20 seconds by default. A higher poll rate will decrease the power consumption
but will increase the response time.
The power is supplied to the EE-420R by two replaceable Alkaline AAA size batteries (not included). The
typical operation time on a set of batteries is 5 years when using quality alkaline batteries, based on a poll
rate of 20 and on average two display updates per day.

Radio Protocol
Modified 802.15.4 (Physical layer and Media Access Control layer).
6.3.1 The physical layer
The physical layer (PHY) provides the data transmission service, as well as the interface to the physical layer
management entity, which offers access to every layer management function and maintains a database of
information on related personal area networks. Thus, the PHY manages the physical RF transceiver and performs
channel selection and energy and signal management functions. It operates on the above mentioned frequency
band. The PHY layer is 100% compliant and is based on direct sequence spread spectrum (DSSS) technique
with a transfer rate of 250 kbit/s.
6.3.2 The medium access control layer
The medium access control (MAC) layer enables the transmission of MAC frames through the use of the physical
channel. Besides the data service, it offers a management interface and itself manages access to the physical
channel. It also controls frame validation, guarantees time slots and handles node associations. Finally, it offers
hook points for secure services. The EE-420R does not make use of the optional network beaconing, instead it
used a polling mechanism to increase power efficiency. Some changes are made to the standard to allow for
more efficient data frames and better power efficiency, especially when nodes are not connected to a base
station.
6.3.3 Security
The 802.15.4 standard 128-bit AES encryption is supported. A secure method for key management is
implemented as well. The encryption is optional though and can be configured via the base station. By default, the
radio traffic is unencrypted.
