1. Precautions
“This RF device operates on the 2.4GHz and Sub-GHz frequency band and can
produce radio interference. The device, therefore, may not be used for applications where
safety of human lives is concerned.”
1) Usage Environment
Take extra caution when using this RF device in the vicinity of other electronic devices and
appliances. Most electronic devices and appliances use electromagnetic waves. Electromagnetic
waves emitted by this RF device can affect other electronic devices and appliances.
If using the device in an explosion hazard area, follow all safety regulations, instructions, and
signals.
2) Storage and Use
Moisture and liquids can damage internal parts and circuit boards if allowed to enter into the device
itself.
Do not place or store the product on a sloped surface. The product may slide and fall off the surface
and damage.
Use the product in temperatures ranging from -25℃to +60℃. Parts and circuits may damage if
used or stored under temperature extremes.
Avoid areas with strong magnetism or subject to magnetism.
Contact between the device and a magnetic object can lead to malfunctions.
Do not place the product near heat-producing kitchen appliances like a stove or a microwave or
in the vicinity of highly pressurized containers.
External impact to the product, such as from being dropped, can damage the screen.
Twisting and bending the product can damage the exterior casing and the internal components.

2. Overview
Gateway make up a system the electronically displays price and other product information that
are traditionally shown printed or written on paper in places like the supermarket.
Here, ESL(Electronic Shelf Label) Gateway receives product price updates from the server and
uploads the new data to the applicable electronic shelf label tags (ESL-Tag), changing the displayed
price information.

5-1 Gateway
- Components (includes installation accessories – bracket, screws)
Installation
a) Drill 4 holes on the wall or ceiling to align with Plates (1). Refer to the attached diagram.
b) Drill two Ф10 holes on the wall or ceiling for Ethernet Cable. Refer to the attached diagram.
c) Align the mounting bracket holes(4) to the holes drilled through the wall or ceiling from step a)
d) SMPS Adapter and Ethernet Cable through the two Ф10 holes made from step b).
e) Use Screws(3) to completely secure the mounting bracket and Wall or Ceiling.

Operation Check
< Connect Ethernet Cable with PoE or Connect SMPS adapter and Ethernet cable first . >
1) Network : ON if Ethernet link is connected
- Check every 1sec whether Ethernet link is connected.
2) 2.4GHz SIL : Blink (duration 1sec) if Server interface layer is operated.
- Check operation of Server interface layer
3) 2.4GHz TML : Blink (duration 1sec) if RF MODEM is operated.
- Check operation of RF MODEM interface layer
4) Sub GHz SIL : Blink (duration 1sec) if Server interface layer is operated.
- Check operation of Server interface layer
5) Sub GHz TML : Blink (duration 1sec) if RF MODEM layer is operated.
- Check operation of RF MODEM interface layer
1) Network LED
2) 2.4G SIL LED
3) 2.4G TML LED
4) SubG SIL LED
5) SubG TML LED

.Installation
a) Map product information and tag IDs.
Each tag has a unique 1) MAC Address that serves as the tag’s ID.
Map 1) MAC Addresses of the tags and 2) barcodes of the products.
Using a PDA f or higher as the operating system and a barcode scanner, scan the tag’s 1) MAC
Address and then the product’s barcode to map.
+
b) Register product and tag mapping information.
Using the PDA’s WLAN feature, register mapping data with the 4) Server.
(1) MAC Address (2) Product
Barcode
(3) Industrial PDA

c) Attach a back rail to the shelf (secure using double-sided tape or screws).
d) Attach end and middle caps to the middle rail.
e) Take a tag that has been mapped from step a) and insert to the middle rail from step d). Here,
make sure to align the tag and the rail grooves properly.
f) Slide in the middle rail to the fixed back rail.
g) Products information on Tags such as price will be updated from the server regularly via
gateway
