-
During testing, it can be attached to a meter that supports
near-infrared communication for data transcription. Users can set rate
parameters, it reads instantaneous variables
Applications:
Based
on 38kHz signal modulation and demodulation, it is a far-infrared
converter. Using state grid RS485 chip, far-infrared pair tube for
Vishay, integrated circuit for TI, 38KHz crystal oscillator as clock
signal source. This product is suitable for electric energy meters,
water meters, gas meters and other instruments with local data reading
function with far-infrared communication ports.
Product Parameters:
1. Modulation and demodulation signal frequency: 38KHz
2. Communication baud rate: up to 2400bps, higher baud rate will reduce the effective range
3. Communication distance and angle: 3-5 meters, ≤15°
4. Working voltage: from 485 terminal, the highest input voltage can reach 40V, meet the commonly used 5V, 12V, 24V
5.
The direction of infrared transmission and receiving is about 120°, not
360°. In the external infrared test, it is not that the closer the
distance, the more stable performance. Since the infrared transmission
is a fan-shaped area, the transmission axis of each tube will be a bit
deviated, which will cause unstable communication when being close
sometimes. It is recommended to keep the distance between 15cm-50cm
during testing. It doesn't matter if the distance is a little longer,
gradually increase the test distance, and it can work normally when the
distance is 3 meters in our test.
6. Infrared can only be tested with
expensive handhelds or other special conversion tools. This needs many
tools and causes inconvenient operation. The converter solves this
problem. Thanks to standard RS485 interface, it is convenient to wire
and simple to use.
Package Included:
- 1 x Far Infrared To RS485 Converter Meter Reader
