Problem transferring program to T100MD888+ from USB to RS232

[aphadke]

Hi,
        I have problem with transferring program to T100MD888+. I had no problem at initial connections. But when I connect to TLServer & hit IR* it says Warning: No resopnse from plc ! I am using USB to RS232 for transferring the program...but it works fine for another T100MD888+ I have. I checked the baud rate & tried to use the RS232 to RS232 port also but gives the same message....even I tired to pause plc & transfer the program....but hard luck...

Plz help me out..
Thx
Atul

If the same program and RS232 convert works on one PLC but does not work on another one, and turning on DIP switch #4 and reset the PLC and you still can't communicate with it using 9600 bps, then it is likely that the board's RS232 port may have failed. please email to: support@tri-plc.com for an RMA # and arrange for return to the dealer for service/repair.
