You use RS232 protocol at the input and the board translates it to RS485.

Hello,
at **broken link removed** the chat 485 convert the RS232 to RS485.
It used the power of the RS232 line (or ext).
work at 9600bauds, or more or less, RC timing.
No CPU... and only TX,RX.
ask for the schematic (free), because it was describe in the french paper.

Re: RS232/485

Hi, RS-485 describes the phisical layer, protocol layer or communication could be anyone you can imagine...
Generaly is <ID><DATA(variable)><Checksum>. Where ID in a master system is 00 and slaves from 01 to 31.

Do not post files that are freely available on the net, why not post a link to bb electronics where everybody can download whatever he/she likes?
