  1. Connection with a CPM2A PLC

    Anyone know how to read the project out from the NT21 HMI?  Those Japanese is suck. they try to make a simply RS232 as complex as possible to let you buy their expensive cable. 
  2. Connection with a CPM2A PLC

    Thanks IO_Rack, I make the DB9-DB9 cable as your diagram, when It connect to CS1W-CIF31 pigtail, it is able to read another OMROM's PLC but not  CPM2A . I see the TD LED on the CS1W-CIF31 flash, and CX-One is trying different baud rate, finally said can not find CPU. There is a NT21-ST121B-E HMI connect to the CPM2A use the the same RS232 port. I try to connect the HMI and CPM2A to read the program, both fail. My CPM-2A have a little switch besides the port and it is set to "ON" Any clue?
  3. Connection with a CPM2A PLC

    the manual said there is another cable CS1W-CN226/626, anyone has DB9-DB9 pin out? If you can share, I will greatly appreciate
  4. Connection with a CPM2A PLC

    I bought Omron CS1W-CIF31 USB-RS232 converter try to read CPM2A, but it is not successful. According the manual I still need a CQM1-CIF02 cable to connect between the USB-RS232 and PLC. Anyone the both side DB9 pin out? I want to make the cable myself instead of paying $50 for a cable.
