Modbus error
#7
Did you try that? This is from the slave manuals.
TROUBLESHOOTING If response from RMC doesn’t happen:
- check connection from RMC and RS232/RS485 converter ;
- check if data outgoing from the RS232 serial port of the PC come in the RS232/485 converter - try to increase the wait time for response ( 300 mS is good);
- check if the transmitted data stream is EXACTLY as in example, monitoring the data on the RS485 serial line with a terminal (i.e. Hyperterminal or other emulator);
- if the RS232/485 converter is not our model EMI-1, be sure the turnaround-time is set in range 1 to 2 mS
