IR Receiver
The board provides an infrared remote-control receiver module (model: IRM-V538/TR1), whose
datasheet is offered in the Datasheets\ IR Receiver and Emitter folder on DE1-SoC System CD. The
accompanied remote controller with an encoding chip of uPD6121G is very suitable of generating
expected infrared signals.
Figure 3-23
shows the related schematic of the IR receiver.
Table 3-21
shows the IR receiver interface pin assignments.

IR Emitter LED
The board provides an IR Emitter LED for IR communication which is widely used for operating
the television device wirelessly from a short line-of-sight distance. Match this IR Emitter LED with
an IR receiver will allow the board to communicate with similarly equipped system.
Figure 3-24
shows the related schematic of the IR emitter LED.

shows the IR emitter interface pin
assignments.
