UDP

Byte Command Parameters Notes

FC Set IP Address 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.

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.

Example (all in Hex):

49 50 2D 63 45 54 55 50 00 00 2A 12 81

00 01 02

IP address of the node with serial number

42-18 set to 129.0.1.2

FD Set

as well (bytes 0-3).
