Bixton Kitchen Buzzer

Just curious if anyone knows if the parameters of the below can be adjusted to change tone and number of bleeps?
The below code works and came from old v3/v4 kitchen buzzer topic and sounds the premade bixton buzzer i am testing.


THe 27,112,48 is the same start as a fairly generic kick code which makes sence i guess since its connecting to the cash drawer port.
However the 100 and 200 are different. Just curious if anyone knows what these represent? Searching obviously comes up with lots of drawer kick topics.
