7.3.16 Setup Expansion Port Event Trigger Jump Phase
Command: "FUN EVE <expansion pin>"
The ‘Event’ function sets a background event trap that is triggered by an external signal on a specific
Expansion Port connector pin. See sec. 9, “Logic Interface: TTL Input and Output” for detailed information
about the Expansion Port.
This command is used in conjunction with the “FUN EVN” command. After setting an event trap with the
“FUN EVN” function, the “FUN EVE” function re-directs the event trigger source to pin <expansion pin> on
the expansion port.
This one time background trap, or interrupt, stays set during the Pumping Program’s entire execution until it is
triggered or reset. This function has no other effect on the operation of the pump until it is triggered.
The event is triggered only when a falling edge (high to low TTL transition) is detected on the expansion port
pin <expansion pin>.
When triggered, the current operation of the pump and the Pumping Program is interrupted, and the Pumping
Program immediately continues operation (jumps to) with Phase number ‘nn’, specified with the “FUN EVN”
function, executed prior to the execution of the “FUN EVE” function. After being triggered, the event trigger
is reset. If an event trigger function is executed while another event trap is still set, the new event trigger will
replace the previous event trap.
The following example, sets an event trap at the start of a Pumping Program to jump to Pumping Program
Phase 5 when a falling edge occur on expansion port pin 3.
PHN 1
FUN EVN 5
PHN 2
FUN EVE 3
7.3.17 Setup Expansion Port Pause and Trigger Level Wait Phase
Command: “FUN EPL <expansion pin>”
Pauses the Pumping Program and waits for a trigger on Expansion Port pin <expansion pin>. The trigger is the
detection of a high to low TTL transition on the specified pin, or a low level when the function is first executed.
7.3.18 Setup Expansion Port Pause and Trigger Edge Wait Phase
Command: “FUN EPE <expansion pin>”
Pauses the Pumping Program and waits for a trigger on Expansion Port pin <expansion pin>. The trigger is the
detection of a high to low TTL transition on the specified pin.
7.3.19 Event Reset
Command: "FUN EVR"
’Event Reset’ cancels a previously set event trap.
7.3.20 Clear Total Volume Dispensed
Command: “FUN CLD”
Sets the total volume dispensed to 0. Both infusion and withdraw volumes are reset.
7.3.21 Override Operational Trigger Default Configuration
Command: “FUN TRG <nn>”
Sets the Operational Trigger (pin 2) to mode setting <n>, overriding the default setup Operational Trigger
Configuration. See Sec. 6.5, ‘TTL I/O Operational Trigger Default Configuration’, for the settings for
parameter <nn>. The default setting for the Operational Trigger is always used to start the Pumping Program.
