Installation
4.2.5
Selecting the mounting location
The system must be mounted in such a way that the straight line of vision between
the two units is unimpaired.
Ø
Aligne both units either vertically or horizonally.
Ø
Ensure that the adjustment aid (on the top) is easily accessible on both units.
Ø
If two ISD systems are operated in parallel, ensure that the units with the same carrier
frequency are mounted diagonally opposite one another.

Ø
If the connector cover is used, observe the longer dimensions in summary due to the
cover (see
Fig. 10-3, Page 53
).
Path length: 0.2 ... 150/180/200 m
Ø
Mount the units at an angle of 180° with respect to each other (
Fig. 4-1
).
The two large lenses must be directly opposite one another.

Path length: 3 ... 150/180/200 m
Ø
If the distance between any position on the mobile station and the fixed station is not
less than 3 m, both units can also be mounted in the same plane (device unit not
rotated through 180°).
Table 4-1
shows the transmitter and receiver aperture angle for a device unit. The light
spot diameter of the transmitter depending on the distcance is shown in
