Revision 08 – 04 May 2018
1 DESCRIPTION AND OPERATION
Vega SI-13 has two design options, varying by data exchange interface:
Vega SI-13-232 with RS-232 interface;
Vega SI-13 -485 with RS-485 interface.
Vega SI-13 pulse counter is designed for counting of pulses incoming to 2 independent
inputs, further accumulating and transmitting of this information via the LoRaWAN protocol to
the gateway through wireless communication within 860-1000 MHz frequency band.
In addition, Vega SI-13 can be used as a security device - all inputs can be configured as
security inputs.
The pulse counter can be used for any utilities’ meters and industrial equipment with RS-
232 and RS-485 interfaces or pulse outputs, including water-, electricity-, and heat meters.
Vega SI-13 can work as a wireless modem or query some meters’ models.
Equipment with NAMUR pulse output is not supported
De-bouncing logics with 5 msec time constant is integrated in the pulse counter. The
pulse counting is carried out for frequencies up to 200 Hz.
The counter is powered by a 8…36 V external power supply.
The counter is configured via USB with special software.
The label on the board contains the information for registering of the device in the
LoRaWAN network:
