WAVESHARE- REBE-TZ42C -LED 4.2 -Inch 3-Color -Graphic

Application

This Specification is applied to ATEC IOT Wireless Electronic Shelf Label. (REBE-TZ42C) REBE-TZ42C is used by retailers for displaying product pricing on shelves. Typically, electronic display modules are attached to the front edge of retail shelving. These modules use Electrophoretic Display (EPD) or similar screen technologies to show the current product price to the customer. A communication network allows the price display to be automatically updated whenever a product price is changed.

1. [Notice]   If the background of display is red, display quality can be decreased. Generally, we recommend that the portion of red color has less than 50%.

2. The battery life time depends on operating conditions
   (Temperature, humidity, wireless environment, image update count…etc)

3. LoS (Line of Sight) : Without any sort of an obstacle between a gateway and end devices.

4. Communication Range depends on surrounding environment.

Absolute Maximum Rating

Environmental Conditions

The normal operating environmental conditions are those as below. In such conditions, ESL must be in conformity with the present specification. The conformity to such requirement must be certified by the manufacturer.

Operating Environment

| Temperature| 10| 23| 30| ℃
Humidity| 45| 55| 65| %RH

Storage Environment

| Temperature| 0| 23| 40| ℃
Humidity| 45| 55| 65| %RH

[Notice]

1. Tag can operate at 0~40℃. But only assure the image quality of EPD at 10~30℃.
2.  Depending on the characteristic of the EPD, it may become reddish by passing time.
3. Moisture and liquid can damage the tag and reduce its life time.
4. Getting a magnetic close to the tag can be degraded the performance. (wireless communication, remote controller, etc)
5. When storing the tag, change it to a white screen, and maintain the proper temperature and humidity.
6. After receiving the product, it should be installed within 3 months.
7. The display glass may break when it is dropped or bumped on a hard surface. (fragile by external impact)

Electrical Conditions

The operating electrical conditions are those as below. In such conditions the ESL must be in conformity with the present specification. All devices can be damaged or non-operated over the specification as below. The conformity to such requirement must be certified by the manufacturer.
