1. Abstract
This manual provides specifications for the EE-750R electronic shelf label (hereafter referred to
ESL
2. Overview
The EE-750R is an Electronics 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-750R switches to a non-802.15.4 standard to lower the
power. That is especially meaningful when the EE-750R is not being used for a prolonged
period of time (e.g. during shipping)
The EE-750R is intended to be operated in combination with a base station such as the EBS-40
which can control a large number of EE-750R and other types of ESL of the same family such
as EE-202 and EE-420.

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-750R by four 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.

6.3. 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-750R 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.
