Connecting to
networks
Each controller in a KMC digital network may be used as either a stand-alone
controller or connected to other controllers in a network. The KMD-5205 and
KMD-5270 controllers can be connected to other KMC controllers through two
different types of networks.
◆
Connections to KMD Tier 1 controllers and BACnet 8802–3 devices use
standard Ethernet wiring and hardware.
◆
KMD Tier 2 controllers and Modbus controllers use EIA–485 wiring and
hardware.
KMC Tier 1 networks
LAN connections
Connect a standard Ethernet cable between the
Ethernet
connector on the
controller and a port on a network hub or router. You may connect up to 31 Tier 1
controllers in a system using Ethernet. In addition to allowing the maximum LAN
controllers, multiple computers can access the system through the network. See
for Ethernet configuration.
KMC Tier 2 networks
Connect KMC Tier 2 controllers to a KMD-5205 or KMD-5270 at the RS-485
connector. The KMC Tier 2 network uses shielded twisted pair cable to connect
controllers together. See
for configuring a
controller for Tier 2 network operation.
Note
KMD Tier 2 controllers cannot be connected to KMD-5205 or KMD-5270 when
the Modus option is enabled.
