What I'm trying to do here is make a HAM
repeater controller for ATV (amateur tv). I
need to send and receive data to/from
various RS-485 devices as well to/from
RS-232 devices (without device ID) i.e.
use RS-485 just as a transport media.
So, I need advice on how to send data
trough MAX RS-485 driver to RS-485
devices with their own IDs and RS-232
devices that have no ID, respectively. An
example would be appreciated.
