7. OPERATION
ADA-1040PC3 is bidirectional protocol converter of SunMaster to MODBUS-RTU protocol,
with
possibility of conversion a baud
rate, a data format (number of data bits, parity bit, stop bits) and interface type RS232 to RS485/RS422.
Additionally, is a separator of RS232 (SunMaster) port to RS485/422 (MODBUS-RTU) port.
If connect to RS232 port the Inverter with Soladin (SunMaster) interface, should connect to RS485/RS422 port RS485 MODBUS-RTU
bus.
Frames of MODBUS protocol having the errors CRC are rejected by the converter.
Frames of SunMaster-Soladin having the errors CRC are also rejected by the converter.
