Figure 2-10 AF 100 bus connection diagram.
When connecting the station to the AF 100 twisted pair bus cable, the
incoming and outgoing cables can be connected either directly to the
terminal header or to a TC505/TC506 connection unit.
The minimum distance between stations is 4 metres. If the stations are
located inside the same cabinet, the minimum distance can be shorter
if the total bus length does not exceed 10 metres.
The TC501V150 is a termination unit for twisted pair cable (150 ohms).
