- 5 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.

Power and battery Parameter Typ Unit Remarks Operating voltage 3.0 V 4x Alkaline AAA size battery Battery life 5 Years Reference: Panasonic LR03XWA 2 updates per day Sleep current <1 µA When the transmitter and receiver are idle Poll rate >5 Per sec. 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-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.

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.
