config com4 to be rs232

[Mr. Robert]

 Hi  all,

I have an cfp2220 cfp.

I have 4 232 device.

How can I config the com4 to send/receive 232 command.

I find from the datasheet it original design for 485.

Any special connection or VI script for convert 232 command through 485 interface to another 232 device.

Thanks.

Robert

You can't.

But what you can do is get an RS-232/RS-485 converter like here. http://www.bb-elec.com/productcat.asp?topLevelid=2

HI all,

Would you suggest the circuit using the 485/232 converter?

Also the simple test program for me.

It's better to let me try in this case.

Thanks

Robert
