will immediately start the next consecutive Phase. This linear sequence of Phases can be altered by certain
functions that direct the Pumping Program to continue operation with a different Phase number. Some
functions can change the order of operation conditionally based on external events.
7.1 How to Enter Pumping Programs
Start by organizing your pumping requirements into specific actions and conditions that can then be
programmed into Phases. For more advance programming methods, common groups of Phases can be
grouped together and repeated multiple times using looping and jump functions.
The current values of the pumping rate, optional “Volume to be Dispensed”, and pumping direction, all
refer to the currently selected Phase. Use the command "PHN" to set the current phase.
To change the “Program Function” of the currently selected program phase, use the "FUN" command
When finished sending the data for the current Phase, use the "PHN" command to select the next program
phase to be set. Now all pumping data will refer to next currently selected Phase. Data for the current
Phase can now be entered.
Continue selecting Phase numbers and entering the infusion or control setup for each Phase of the
Pumping Program. The entire Pumping Program will be stored in non-volatile memory.
Use the ‘STOP’ function (FUN STP) to stop the pump and end the Pumping Program. If the Pumping
Program does not operate the pump continuously, the last Phase of the Pumping Program must be a
‘STOP’ function (unless the last Phase number is the maximum Phase number).
When the Pumping Program is started, with the TTL I/O input, or RS-232 command, the Pumping
Program will begin operating from Phase 1.
Very complex dispensing Programs can be created with the Program functions available. Section 7.3
contains a detailed description of all the functions.
7.2 Clearing The Pumping Program
To clear out the pumping program memory and reset communication parameters, send the command:
"*RESET"
7.3 Program Function Descriptions
7.3.1 Rate Function
Command: "FUN RAT"
This is the most basic function to simply command the pump to pump to dispense and a specific rate.
Defines a pumping function with a fixed pumping rate. This function defines a pumping setup consisting
of the pumping rate, optional “Volume to be Dispensed”, and pumping direction. Use the ‘RAT’, ‘VOL’,
and ‘DIR’ commands to set or review the Rate Function's setup. For continuous pumping, set the “Volume
to be Dispensed” to 0.0.
7.3.2 Increment Rate Function
Command: "FUN INC"
The increment and decrement functions operate the same as the ‘RATE’ function, except that the specified
rate is added (‘INC’)or subtracted (‘DEC’) from the current pumping rate. The current pumping rate when
the function is executed is the base pumping rate for the function. If no base pumping rate exists, such as
when executing a pause function or when the Pumping Program is first started, a Program error will occur
and the Program will stop.
The pumping rate units will be the same as the base pumping rate, and therefore cannot be set, or queried,
with the pumping rate increment or decrement value. As with the ‘RATE’ function, a “Volume to be
Dispensed” and pumping direction can be specified for the increment and decrement functions.
When used within a Program loop, the pumping rate can be incremented or decremented in small step
