Coordinator MIRT-557, variation 2

Designation and application field

MIRT-557 is used for control of a MESH-network in radio channel 433 MHz and 2400 MHz.

It provides a transparent access to devices of a MESH-network and lets control devices in the automatic and manual modes as well.

It uses the frequency band in the range 433 MHz, has power of 10 mW, a frequency band in the range of 2400 MHz, has power of 100 mW, therefore no permissions are needed to use frequency bands and execution of a registration of radio electronic equipment.

It has two SMA-connectors for connection of remote antennas in the range of 433 MHz and 2400 MHz respectively.

The interface type of the coordinator with equipment of the wired communication channel consists of two separate RS-485 for radio channel 433 MHz and 2400 MHz respectively.
