ADA-11040 converter is a device used for connection together devices with RS485/RS422 interface via wireless RF network.
The converter transmits data with baud rate from 1200bps to 115200 bps via RS485/RS422 interface, and steady data format: 8 data bits, None parity bit, One stop bit (8N1).
ADA-11040 converter has screw terminals blocks for connection of RS485/RS422 , power supply and SMA connector for RF antenna.
The converters work in the same radio channel, create wireless RF network.
ADA-11040 uses signals:RX+, RX-, TX+/A, TX-/B of RS485/RS422 for operation. To RS485 bus, constructed on the base of ADA-11040, can be connect 32 devices operating in half duplex mode to RS485(2W) bus and full duplex mode to RS485(4W) bus – for short data frames. The converter is adapted to supply an external voltage source from 10V to 30V and power 2W. Has implemented protection against opposite polarization of power supply and over-voltage protection on RS485/RS422 bus. ADA-11040 has galvanic isolation between power supply and RF and RS485/RS422 interfaces, has also optoisolation between RF and RS485/RS422 interface.
Transmission range in wireless RF network:
- in buildings - from 30m to 300m
- in an open area up to 1000m,
The transmission range can be enlarged by use the additional direction
antennas.
