Preparation
Observe the following points before installing the data transmission unit:
·
For each data transmission path one device of type
DDLS 170/xxx. -xxx and one of type DDLS 170/xxx. -xxxx is required.
·
The data transmission path can be oriented either horizontally or vertically.
·
For trouble-free data transmission, ensure
- unimpeded optical connection between transmitter and receiver
- precise alignment
- clean lenses
·
Parallel operation of several data transmission paths:
When arranged with shifted frequencies, two parallel data paths can be operated
with a separation 0.3 m (see Fig. 20).
The parallel distance to a third transmission path can be calculated as follows:
parallel distance = 0.025 x range (however, at least 2.5 m)
