2.6.3.2 Memory Channel, Dispense Pressure, and Dispense Time Read Command
This command returns the dispenser’s current memory channel, Dispense Pressure value, and Dispense Time value
to the client.
Client command and data: (STX) + 04 + UD-- + C3 + (ETX)
The above text packet in hexadecimal format:
STX 0 4 U D space space C 3 ETX
0x02 0x30 0x34 0x55 0x44 0x20 0x20 0x43 0x33 0x03
NOTE: “D0” is the letter “D” followed by the digit “0.”
Return Format: D0ChcccPDppppDTtttt
ccc: The 3-digit memory location from 0–399. The dispenser will automatically limit value to prevent any errors.
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 dispenser.
ttttt: The 4-digit dispense time value excluding the decimal point. The valid range is 0.000 to 9.999. This command
truncates the last decimal place of the dispense time. This was done to make this command compatible with
the Musashi FX808 protocol.
Interpreting the pressure setting from the return feedback value:
Pressure Unit
Value Received from the
Dispenser (pppp)
Pressure Setting
psi 0000–1000 0.0–100.0 psi
kPa 0000–6895 0.0–689.5 kPa
Bar 0000–6895 0.000–6.895 bar
EXAMPLE: If the current memory location is 1, the pressure setting at the memory location is 50.0 psi, and the time
setting is 1.005 s, the text packet received from the dispenser is:
(STX) + 13 + D0CH001PD0500DT1005 + 55 + (ETX)
Length of the response text packet: Decimal 19 or hexadecimal 0x13
The above text packet in hexadecimal format:
STX 1 3 D 0 C H 0 0 1 P D 0 5
0x02 0x31 0x33 0x44 0x30 0x43 0x48 0x30 0x30 0x31 0x50 0x44 0x30 0x35
