Figure 13. Wiring the IR Port
Connect the port directly to the wired IR port of another device. Or insert the wires from
up to four IR Emitters into the IR port and place the heads of the emitters over or next
to the IR signal pickup windows of the devices. For wiring, see the following diagrams
or the IR Emitter Installation Guide (available on www.extron.com).
NOTE: Each emitter must be within 100 feet of the HCR 102 for best IR control
results.
