5.2 Optical Alignment
After powering the transmitter and receiver the first operation is optical alignment.
Optical alignment consists of aligning the optical axis of the transmitter and receiver modules.
This alignment is conducted on each module, using the integrated aiming system, starting at
the transmitter.

1. On the side of the optical module is a small
mirror which acts as a viewfinder for the
alignment. Look into the viewfinder from a
distance of about 10-15 cm, as shown in the
figure.
2. Alignment consists of viewing the
opposite module using a system of
internal mirrors.
