Communications Problem with Omron PT NS12 to Mitsubishi FX2N

<p>I have the problem of communicating FX2N-128MT Mitsubishi PLC to NS12 Omron PT. My HMI has a serial port connected through the port of FX2N-232-BD installed in FX2N-128MT. My wiring configuration is:
<pre>
NS12 PT FX2N PLC

2............2

3............3

9............5

4-5 4-6
</pre>
<p>Are my wiring configurations correct?
How can I configure FX2N-232-BD port?
Communication protocol I will use also to configuration?
What other configuration will I make in FX2N and/or NS12 PT to communicate them?

<p>Thanks for help.
