Connecting a Two-position Switch to the Digital Input Port
•
Port Configured
— Input with pull‑up (switch 2 closed)
•
Two Position Switch Open
— Digital input reads +5 VDC = Logic High
•
Two Position Switch Closed
— Digital Input reads 0 VDC = Logic Low
Control Ports — USB Adapter
IR Port
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 9. 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 control system for
best IR control results.
