GSM/GPRS-gateway MIRT-811 (modification 2)
The device is used as a part of the data collection and communication modules MIRT-851 and MIRT-853.
It has to be installed on a DIN-rail.
Retransmitter MIRT-181 and MIRT-581
Retransmitter is designed for increasing of the communication coverage area. The devices are fixed on the power transmission line supports.
AC power supply ~ 230V
Data reading master MIRT-145
Data reading master MIRT-145 integrates into one network up to 300 devices. The device was developed for work with radio channels 433 MHz and 868 MHz.
Data collection and communication device MIRT-881
Data collection and communication device MIRT-881 has the following functions:
- collection, accumulation and storage of data from metering devices (up to 4 096),
- collected information communication on request at the high level of information and measuring systems
- control and synchronization of the current time in the meters,
- embedded GSM-modem
GSM-gateway MIRT-851/ MIRT-853
GSM-gateways MIRT-851 and MIRT-853 are equipment set for remote access to the object via GSM-network. The device installation is recommended on supports. Its' powered by AC power ~ 230V
Data reading master MIRT-141
Data reading master MIRT-141 is designed for access to metering devices with radio modules 433MHz. MIRT-141 сonnects to a laptop or personal computer using USB.
Data collecting master MIRT-541
Data collecting master MIRT-541 is designed for access to metering devices with radio modules 2400MHz. MIRT-541 сonnects to a laptop or personal computer using USB.
The carrier frequence in unlicensed range:
- 433 MHz
- 868 MHz
- 2400 MHz
Automatic network construction, high reliability of data communication.
The usage of the ready public comminication channels GSM/ GPRS and usual SIM-cards with dynamic IP-address - low costs on the system deployment. There are 2 slots for SIM-cards installation of other operators - high reliability of the data communication.
LoRaWAN is open protocol for high-capacity networks (one network includes up to 1 000 000 devices) with long range of operation (up to 10-15km in open areas, 4-5km in urban areas) and low power consumption.
Asynchronous half-duplex interface with physical layer in the differential pairs type and support up to 256 devices.
CAN-network of the bus topology with physical layer in the differential pair type, according to the ISO 11898 standard.
The work on twisted pair in full-duplex mode at the rate of 10Mb/s, the static IP-address.
Optical infrared interface (IR port) for individual data communication with meters
