4.3 ESTTL Spark Setup
The purpose of the ESTTL Spark Setup window is to configure the operation of the first Engine Synchronous TTL
(ESTTL1) Output module. The TTL outputs of this module, in the third slot of the MXIe Expansion Chassis , are
intended to be used for commands to smart ignition coils . The ESTTL Spark Setup window contains a tabbed
pane with nine tabs:
ESTTL 1 TDC Channel Mapping Tab: Used for assigning Top Dead Center (TDC) values to each ignition coil
commands.
Ch1-8 Tabs: Used for configuring spark command pulse sequences that are associated with each of the eight
ESTTL 1 output channels.
Each of the ESTTL 1 output channels are non-multiplexed and therefore can be independently controlled.
The ESTTL module is an optional module for the NI 9155 MXIe Expansion Chassis. This setup window is only
applicable if the ESTTL module is inserted in the assigned slot.
