    Default RS232 with multiple slaves

    Hi

    I want all the slaves to receive the same bytes sent by the master using RS-232 at 2400 baud, no communication from the slaves are needed.
    I know that RS-232 communication are not supposed to be used with multiple slaves but maybe if I use an RS-485/422 driver as in the picture below?
    what do you all think, Is it worth trying or does anyone see any obvious problems with this solution?

    The total cable length is about 500 meters.
