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.
11.1,
TTL I/O Operational Controls
). The 2 letter configuration Setting parameter to the right of the colon (:)
is defined in column ‘Setting’ as follows:

TTL I/O Directional Control Input Configuration
aa
Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction.
(See sec. 11.1,
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: 6.8.1
