Connection to Visible or Infrared LEDs
Connect infra-red LEDs to the outputs according to the figure below. A
series resistor of 100 ohms 2 Watt should be connected between the
infrared LED and the output.

Use 2 or more for greater range

Figure 2.16 - Output Connection to Infrared LED
For Infrared LEDs, the value of this resistor depends on the distance
from the LED to the appliance and the incident angle . As a rule of
thumb, within 4 meters and 15 degrees, use 100 ohms (2 Watt) Aim to
mount the infrared LED as close as possible to the receiver, in a clear
line of sight to the receiver. If the Infrared LED is positioned further
from the receiver or is pointed at a larger angle, it may be necessary to
use two or more infrared LEDs in series as shown in the figure.
Infrared LEDs from a single output may be positioned to control several
appliances within line of sight.
Note that indicator and infrared LEDs have polarity and should be
connected in the right direction.

Figure 2.17- Output Connection to Test Lamps
A valuable tool for testing output programming are 12V lamps
connected to the Output terminal Blocks. Unlike LEDs, these lamps do
not have polarity, and can be connected directly to the Output terminals
without the need for a series resistor. These lamps take around 80 mA
current so they impose a real load on the outputs, similar to relays.
