Auto-Find Example
The example has a button and a list box as
follows:
• When the button is clicked function
button1_Click() is called that sends a UDP
broadcast on port 46000 containing
“MonitIR?”.
• The list box is populated with the replies
contents
This could be rejigged to suit a multithreading
app by using non-blocking calls instead of
using the ReceiveTimeout.

Parse the response as follows
Bytes[0..24] = “MonitIR-“+serial_number,
bytes[25] = hardware_version, bytes[26..31] =
mac address, bytes[32..47] = location
Hardware version identifies the units as
MN4000 / MN4100 and reflects hardware
defined signals.
The hardware signals are PB[15:14] copied as
HWVersion[1:0]
