AquaMatic to MODBUS-RTU Protocol Converter* The prices are given in the response to the offer.
Protocol converter AquaMatic/SP100 to MODBUS-RTU ADA-1040PC4 is a device solves a problem of connection the RCU (Rainwater Control Unit) AquaMatic Industrial, equipped with RS232 interface and communicate by AquaMatic protocol to multipoint RS-485 bus with devices communicate by MODBUS-RTU protocol.
Simultaneously, the converter convert RS232 to RS485/422 standards, with setting of data formats. Depending on configurations, can be set baud rate, data bits, parity, number of stop bits. The setting can be different for RS232 and RS485/RS422 port.
The converter does not require power supply from RS232 port and support the asynchronous transmission data with baud rate 230,4kbps.
The ADA-1040PC4 has DB-9F connector for connecting RS-232 interface of RCU AquaMatic and screw terminal block for connection of RS-485/422 bus and power supply. The DB-9F connector is DCE type to connecting RS232 interface.
The ADA-1040PC4 uses Tx, Rx and GND signals for communication with RS232 interface.
Overvoltage protection was made on base safety diodes and fuses on each RS485/RS422 lines.
