This product is based on a standard industrial-grade RS485 interface to near-infrared converter. The RS485 interface ports are defined as VCC, GND, A, B. This infrared is near infrared, and its infrared wavelength is 940nm. There is a ring magnet on the converter, which is adsorbed on the instrument for communication. Overseas, like electric meters,Most instruments such as water meters and gas meters use near-infrared communication. This converter is transparent Transmission, applicable to the entire protocol; it is mainly used in research and development, debugging, testing and other occasions, Realize infrared reading of data.

Product specifications

1. The length of this cable is 2m and it has a built-in silabs CP2102 chip. For more information about this chip, please check the silabs official website.

2. Standard industrial grade RS485 interface, the 4 wires are red-VCC, black-GND. Green-A. Yellow-B. The voltage input range is DC5V DC24V. Optocoupler/power isolation type RS485 to near infrared IR

3. The near-infrared end of the converter uses an industrial-grade IR infrared pair tube with a wavelength of 940nm.

4. Baud rate supports 300pbs\600pbs\1200pbs\2400pbs\4800pbs\9600pbs\19200pbs

5. Use UL2464 signal control soft wire, the wire length is 2 meters.

6. The maximum communication distance between the infrared end of the converter and the infrared of the instrument is 30mm; this distance will vary depending on the instrument being communicated with.

7. With a magnet suction head to connect the meter, it is convenient to connect to the meter reading.

8. Data transparent transmission, supporting all communication protocols; such as supporting IEC 62056-21, IEC 1107, DLMS, MD BUS and other protocols

9. RS485 and near-infrared IR are isolated by optocoupler and isolation power module; anti-interference and stable communication.
