Mitsubishi GOT A953-TBD HMI is not communicating with Nittoku nsc30 MC310

I am trying to connect GOT-A953-tbd HMI with Nittoku NSC30.
Actually,

earlier GOT-A953-tbd HMI was used to communicate with Nittoku NC350 and it was working perfectly,When it got damaged over time(Screen became white),I bought new GOT-A953-tbd and installed OS,communication drivers, set baud rate ,downloaded program from PC(HMI communicated with PC).
But when iam trying to connect HMI to Nittoku NSC30 ,then it is not connecting.I have tried all baud rates available on HMI BUT Still no communication.Rs232 protocol is used for communication.
HMI software: GT designer 2 classic .

while installing drivers in HMI I choosed YASKAWA GL/CP9200(SH/H)/CP9300MS drivers.Since this was the only option for Yaskawa PLC in GT designer 2.
I am new to PLC.Kindly guide i this regard.
