EE-750R Specifications manual

1. Abstract
This manual provides specifications for the EE-750R electronic shelf label (hereafter referred to
as “ESL”).
as “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.
