Digital Input Monitoring Port
This port monitors digital input from external devices. Connect a two wires as follows:

Digital Input Monitoring Port
•
Pin 1 = signal
•
Pin 2 (G) = ground.
The port measures two states: high and low. Digital input is triggered by an external switch or voltage between the digital input
pin and ground. The threshold voltages are:
•
Low to high 2.8 VDC
•
High to low 2.0 VDC
If the connected device does not provide its own power, use Global Configurator to configure an internal pull-up resistor.
Control Ports — USB Adapter
IR
Insert the wires from an IR Emitter into the IR port and place the head of the emitter over or next to the IR signal pickup window of
the device being controlled.
Connect two wires to the IR port, as shown in figure 6. If both the IR port and contact closure port are used, the ground pin must
be shared by both devices.
NOTE:
Each emitter must be within 100 feet (30.4 meters) of the TLC Pro control system for best IR control results.

IR Connector
The IR port can accept a single IR emitter (see figure 7), a dual IR emitter (see figure 8) or two single IR emitters, tied in series (see
figure 9).
