RS485

[C.Tommy]

Hello,

I have a Pic 16F877. I want communicate with the Pic using the RS485 seriell Port.

So I use a Max481 !

I have the problem that I cant`t find a function in CVI for using the RS485.

Only the RS232.

Is there anyway a function for RS485 or what can I do?

Can I use the RS232 function for the communication?

What is different? Only the Baudrate?

Thanks for your help !!!

If you want to use RS485 comms on a PC, you will need an RS485 interface. You can get direct RS485 adapters, or converters for the RS232 serial port (and I guess you can probably get USB adapters these days). Whatever you get, the RS485 interface is normally programmed just like an RS232 interface so the CVI RS232 library would normally be used.
