It's actually exactly what it is, although i have no idea why it's there by default.
What happens is that the LB sends an UDP packet with the data "default send string". It's not replaced by anything, just plainly "default send string".
I suppose that as long as you leave your receive string empty the F5 would not care if you get a valid response or not, just as long as you actually get a response.
To know what to replace the send strig and receive string with to get a more accurate monitor you'd have to know the syntax of the application.
