You do not need an SC09 cable to connect to an A1sJ71UC24 module. You only need an RS232 Null Modem cable but you need to have some of the handshaking pins linked together for this to work. The correct pin out is in the manual for the module which should be available on the Mitsubishi web site. You also need to make sure that you have the right module selected in your programming software (C24 in GX Developer) and the the module settings match the software settings. You will need the manual for this as well.

Apologies for incorrect info

Andybr & cjd1965 Thanks a lot for your info.
I have found the 9pin connection diagram on A1SJ71UC24-R2 user's hardware manual 5.1(1)
Thank you
