The RS485 interface permits the simultaneous connection and
operation of a maximum of 32 bus users per bus segment. Fur-
ther bus segments can be constituted via bi-directional repeaters,
and thus the number of bus users can be extended to max. 127.
10.3 Transmission Speed and Line Length
The transmission speed with the datalogger
COMBILOG 1020
can be adjusted between 2,400 baud and 38.4 kbps. The permis-
sible line lengths are reduced with increasing transmission speed.
At the given transmission speeds these line lengths are about
1,200 m (3,900 feet) per bus segment. With 3 repeaters topolo-
gies with a dimension of max. 4.8 km (3 miles) can be set up.
