MODBUS-ASCII to MODBUS-RTU Protocol Converter
ADA-1040PC1

MODBUS-ASCII to MODBUS-RTU Protocol Converter* The prices are given in the response to the offer.
Protocol converter MODBUS-ASCII to MODBUS-RTU ADA-1040PC1 is a device solves a problem of connection RS232 devices (communication MODBUS-ASCII protocol) to multipoint RS-485 bus with devices communicate by MODBUS-ASCII protocol.
Simultaneously, the converter can convert RS232 to RS485/422 standards, with setting of data format. 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 230,4 kbps.
ADA-1040PC1 has DB-9F connector for connecting RS232 interface and screw terminal block for connection of RS485/422 network and power supply. The DB-9F connector is DCE type to connecting RS232 interface in use of RS232 extension cable (a typical modem cable) without interleaving of Rx with Tx. Overvoltage protection was made on base safety diodes and fuses on each RS485/RS422 lines.
