UDP Byte FC Command Set IP Address Parameters First 8 bytes must be set to the string IP-SETUP (Hex 49 50 2D 53 45 54 55 50). Next 2 bytes have to be set to 00. Next 2 bytes must contain the serial number. Next 4 bytes have to be the new IP address. Notes This block can be sent as a broadcast, because the serial number is unique. It provides one method to set the IP address of the Device Server if is on the local network and the serial number is known. Remember, broadcasts are only 'heard' on the subnet on which they are generated. No reply is sent by the Device Server, which restarts using the new IP address after the block is received.
