Note
Set the End-of-Line termination at the controllers where only one wire is
attached to the A and B terminals.
BACnet 8802-3
(optional)
Connect models with the BACnet option to the BACnet internetwork through the
same Ethernet 10Base-T connection as the Tier 1 connection. For access to devices
on a BACnet internetwork you must do the following:
◆
The BACnet internetwork must include at lease one 8802-3 network.
◆
The controller must be connected to the same Ethernet broadcast domain
segment as one of the BACnet 8802-3 networks.
◆
If the internetwork does not include an 8802-3 network, install a router to
route traffic from the existing BACnet network protocols to Ethernet 8802-3.
For internetworks that include MS/TP or BAcnet IP, use a BAC-5050. For
addition details on BACnet networks, see application note AN0404A,
Planning BACnet Internetworks
, which is available on the KMC web site.
