7.4 TTL I/O Operational Trigger Default Configuration
aa
Configures the default mode of the TTL I/O ‘Operational Trigger’ (pin 2) that will control the
Pumping Program’s operation. This default setting can be overridden within a Pumping Program. (See sec. 10.1,
TTL I/O Operational Controls ). The 2 letter configuration Setting parameter to the right of the colon (:) is defined
in column ‘Setting’ as follows:
Setting
RS-232 Command Setting
FUN TRG <n>
<n> =>
Name Function
Ft 0 Foot Switch Falling edge starts or stops the Pumping Program
FH 1 Foot Switch Hold Falling edge starts the Pumping Program
Rising edge stops the Pumping Program
F2 2 Foot Switch Reversed Rising edge starts or stops the Pumping Program
LE 3 Level Control Falling edge stops the Pumping Program
Rising edge starts the Pumping Program
St 4 Start Only Falling edge starts the Pumping Program
t2 5 Start Only Reversed Rising edge starts the Pumping Program
SP 6 Stop Only Falling edge stops the Pumping Program
P2 7 Stop Only Reversed Rising edge stops the Pumping Program
rL 8 Start on Low Level Start Pumping Program on a low level
rH 9 Start on High Level Start Pumping Program on a high level
SL 10 Stop on Low Level Stop Pumping Program on a low level
SH 11 Stop on High Level Stop Pumping Program on a high level
oF 12 Trigger off Disable trigger
Et 13 Trigger Event Pumping Program Function Only:. Trigger an
event instead of stopping the pump
bt 14 Button Trigger Event Pumping Program Function Only: Pressing ‘Stop’
key triggers an event instead of stopping the pump
7.5 TTL I/O Directional Control Input Configuration
aa
Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction. (See
sec. 10.1, TTL I/O Operational Controls ). The 2 letter configuration parameter to the right of the colon (:) is
defined as follows:
Setting Name Function
rE Reciprocating Pumps Falling edge: Infuse; Rising edge: Withdraw
dU Dual Pump Falling edge: Withdraw; Rising edge: Infuse
The setting names are relevant to a 2 pump system, whereby the ‘Directional Control Input’ TTL pin is attached to
the second pump’s ‘Pumping Direction Output’ TTL pin.
In addition, “Directional Control Input” will affect how the “Sticky Direction” function operates. See “ Sticky
Direction”, sec: 5.8.1
