To select TTL input functions and the control type from the touch screen,
go to the
INPUT/OUTPUT
touch screen page (see Figure D-4 ).
TTL Input Control Types
The ICS-2000 TTL inputs respond to four types of
signals to accommodate different controlling devices.
The default control type,
Normal Edge
, is compatible
with the output signals provided by Dionex modules.
If the device connected to the ICS-2000 does not send a normal edge
signal, select the appropriate control type. Refer to the documentation
provided with the controlling device and the information below to select
the correct type.
•
Normal Edge : In normal edge
operation, the negative (falling)
edge of a signal turns on the
function. For example, for the
Load/Inject
function, the
negative edge switches the
injection valve position to Load.
