2.6.3.3 Pressure Time Vacuum Read Command

This command returns the Dispense Pressure, Dispense Time, and Vacuum values of the specified address. This
command also update the LCD screen to the specified memory location.
Client command and data: E8ccc
ccc: The 3-digit memory location from 0–399. The dispenser will automatically limit value to prevent any errors.
EXAMPLE: To read the pressure, time, and vacuum values in memory location #1, the text packet is:
(STX) + 05 + E8001 + 8D + (ETX)
NOTE: This command changes the current memory location in the dispenser as set in the command (e.g., 001 in
above example command), in addition to returning the values for pressure, time, and vacuum.
The above text packet in hexadecimal format:
STX 0 5
0x02 0x30 0x35
NOTE: "D0" is the letter "D" followed by the digit "0."
Return Format: D0PDppppDTtttttVCvvvv
pppp: The 4-digit pressure setting excluding the decimal point. This is a unitless value. The valid pressure ranges
and decimal point are determined by the pressure units currently selected in the dispens
ttttt: The 5-digit dispense time value excluding the decimal point. The valid range is 0.0000 to 9.9999 seconds.
vvvv: The 4-digit vacuum setting excluding the decimal point. This is a unitless value. The valid vacuum ranges and
decimal point are determined by the vacuum units currently selected in the dispenser.
