To make wiring easier, you can connect the STP781x screw terminal panel to the DT7816 module. The connectors on the screw terminal panel mate directly to the Analog I/O header, Digital I/O header, and Digital Function headers on the module.
The following figure shows the layout of the STP781x.
The following table lists the screw terminal assignments for the STP781x.

Tachometer Input |
aThe
DT7816 does not support PWM signals; therefore, screw terminal block TB3
is not used on the STP781x screw terminal panel when used with
the DT7816 module.
bBy
default, general-purpose inputs 0 to 7 are configured as digital input
signals and
general-purpose outputs 0 to 7 are configured as digital output
signals.
cFor
the DT7816, the only signals accessible through screw terminal block TB6
are the tachometer input
and the digital ground signals.
