How to make RS485 (I used MAX1487) power supply? My problem is when my system powered up noise of MAX1487 added to supply voltage.
 

RS485 problem!

Can you be more specific! RS485 converters are noisy when you are changing between receive and transmit state. Therefore you have to take care with the supply voltage. One solution could be to use a voltage regulator with good load regulation to overcome this issue. Bypass cap are always welcomed!
