Hardware
3.1.3.3 Fieldbus Connection
The connection to the fieldbus is made via an RJ45 connector, which is also
called a "Western plug." Wiring for the RJ45 socket on the fieldbus controller
adheres to 100BaseTX specifications. It is mandatory to use a twisted pair ca-
ble of category 5 as a connecting cable. Cable types S-UTP (Screened Un-
shielded Twisted Pair) and STP (Shielded Twisted Pair) with a maximum
segment length of 100 m can be used.
The connection point is lowered for mounting into an 80 mm-high switchgear
cabinet after the connector attachment.
Attention:
The bus connection is approved only for use in LAN networks, not for the
connection of telecommunication lines!
In addition to BACnet/IP, the controller also supports the BACnet/PTP proto-
col. The controller can communicate, when connected to the RS232 interface,
with other PTP-capable devices through a modem connection (half router).
The SUB-D connector for the RS232 interface is wired as follows:

The pin arrangement corresponds to the RS232 DCE arrangement. This allows
the use of customary 9-pole 1:1 socket/plug cables for the direct connection of
a PC.
