Totals etc..).

be sent 8 times with a delay of 500ms.

Note: When the cash register requests the weight information, unit
price, price to pay, the scale sends back the data when the weight is
stabilized. So, it can last up to 1 or 2s.
P = Unit Price
W= Weight
UP= Unit Price
PtP=Price to Pay
If information is not available (too much weight, nul unit price, etc…)
the scale sends the error code “3Ch” in W4
