Using RS-485?

Hello,

I should establish a test connection. With the RS-485 port on the testbed for mbed I should receive and spend something on the terminal.

How do I do that? Must it not as another device what ever once sent something which can be received? Or can I also simulate it with the mbed?

How should the jumpers be set to? I should turn off the speaker jumper and turn on the RS-485 jumper. Does that mean if it is on, the "plastic thing" :D on both rods or just on one?

(It will ultimately serve a serial communication between two interlockings produce for trains, to document all actions they take place)

(Sorry for my bad english) :)

Please help me :) (I ask my question in the forum, but I hope here I got an answer faster :D)

Hi,

You talk about using jumpers and connection with the RS485 - what board are you using?

Thanks

The problem has been solved, but thanks. :) (I'm using the testbed board from Elektronikladen)
