1. Introduction
R211 is a long-distance infrared learning device based on the LoRaWAN open protocol (Class C).
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power
consumption. Compared with other communication methods, LoRa spread spectrum modulation
method greatly increases to expand the communication distance. Widely used in long-distance,
low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low
power consumption, transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure
interoperability between devices and gateways from different manufacturers.
This device has been certified by the LoRa Alliance and is allowed to use the following logo on the
product:

4. Set up Instruction
On/Off
Power on Plug in DC 12V Adapter
Power off Remove Adapter.
Note:
1. On/off interval is suggested
to be about 10 seconds to avoid the interference of
capacitor inductance and other energy storage components.
2. Press any function key and plug in adapter at the same time; it will enter
engineer testing mode.
Network Joining
Never joined the network
Turn on the device to search the network.
The status LED stays on for 5 seconds: success
The status LED remains off: fail
Had joined the network
Turn on the device to search the previous network.
The status LED stays on for 5 seconds: success
The status LED remains off: fail
Fail to join the network
(when the device is on)
First two minutes: wake up every 15 seconds to send request.
After two minutes: enter sleeping mode and wake up every 15 minutes to send
request.
Note: Suggest checking device verification on gateway.
Button Function
Erase IR records Press and hold the IR button for 5 seconds and the status LED flashes once.
Restore to factory setting Press and hold the reset button for 5 seconds till status LED flashes for 20 times.
And then R211 will reboot.

5. Control Command
R211 receive commands from gateway to absorbs and sends IR spectroscopy
1. Learn IR Spectroscopy
Gateway sends “NEW IR learn request” to R211 to enable learning mode. When the status LED light up,
press the button of the remote controller against R211 to learn IR command. After learning process, the status
LED turns OFF and R211 sends “NEW IR learn Confirm response” command to gateway.
2. Emit IR Spectroscopy
Gateway sends “AIR IR Apply request” to R211 and then R211 emit the corresponding IR spectroscopy. After
that, R211 response message to gateway. If success, status LED flashes once. Otherwise, status LED flashes 3
times.
3. Erase command
Gateway sends “Erase IR request” to R211 to remove the recorded IR code.
The detail of the command set is listed as below.

6. Installation
This product does not have waterproof protection. Please place it indoors.
The effective IR range of Z211 is 30M (apparent distance), please hang the product on the ceiling or the wall. Try to
make all the infrared equipment to be controlled within IR effective range, and no other objects block.

7. Important Maintenance Instruction
Your device is a product of superior design and craftsmanship and should be used with care. The
following suggestions will help you use the warranty service effectively.
•Keep the equipment dry. Rain, moisture, and various liquids or moisture may contain minerals that
can corrode electronic circuits. In case the device is wet, please dry it completely.
•Do not use or store in dusty or dirty areas. This can damage its detachable parts and electronic
components.
•Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy
batteries, and deform or melt some plastic parts.
•Do not store in a cold place. Otherwise, when the temperature rises to normal temperature, moisture
will form inside, which will destroy the board.
•Do not throw, knock or shake the device. Rough handling of equipment can destroy internal circuit
boards and delicate structures.
•Do not wash with strong chemicals, detergents or strong detergents.
•Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
•Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may
also explode.
All of the above suggestions apply equally to your device, battery and accessories. If any device is
not working properly.
Please take it to the nearest authorized service facility for repair.
