  3. Hello. I am having 22 slaves communicating to a master on rs485 half duplex.i have selected baud rate as 38400 on a length of 800m.The problem is out of 22 devices only six are communicating .i have checked wiring,inserted termination resistor but still not getting rest of the devices alive.is it that i have selected high baud rate on a long length?this is the only problem as i am seeing it.can somebody help me on this issue
