Connection and Architecture Options

You can choose from several different options to connect the Commission mobile application to one or more BACnet/IP controllers.

Connect by Wire

You can use a CAT5e or CAT6 Ethernet cable to connect a Windows laptop computer running the Commission mobile application to one or more BACnet/IP controllers, using either of two methods:

  • A direct connection to a free Ethernet port on a controller

  • A connection to an Ethernet switch to which one or more controllers are also connected

Important:

When connecting the Commission mobile application laptop computer to one or more BACnet/IP controllers by wire, you must use one of three methods of IP addressing:

  • Include a DHCP server to assign dynamic addresses to the controllers.

  • Where a DHCP server is not included, use AutoIP to assign dynamic addresses to the controllers.

  • Where a DHCP server is not included, assign static addresses to the controllers.

Note:

You do not need to know the IP address of the Commission mobile application because it is not required for BACnet device discovery. For more information, see BACnet Device Discovery .

Note:

When the BACnet/IP controller's Ethernet port 2 is not used by the controller network, you can connect the Commission mobile application using that port without disruption or additional hardware. When the BACnet/IP controller's Ethernet port 2 is used by the controller network (for example, in a daisy-chain or RSTP network topology), you can add a temporary switch or hub to ensure that connectivity is maintained while the Commission mobile application is in operation.

If Ethernet port 2 will not be used, you can disable this port for network security purposes by configuring the Ethernet port 2 property on the Basic tab of the BACnet/IP controller. For more information, see BACnet/IP Controller Settings Properties – Basic Tab .

Connect Wirelessly

Connect the Commission mobile application wirelessly to a BACnet/IP controller network, using a WiFi router or a wireless access point.

Wireless router

In many cases it is possible to set up a temporary WiFi network, using a WiFi router that contains a DHCP server. The DHCP server provides IP addresses to the BACnet/IP controllers and the Commission mobile application. The router you choose must have a configurable IP address range.

Wireless access point

You can also connect the Commission mobile application to the controller network using a wireless access point. The access point must be networked with a DHCP server, which serves up the IP address. Typically the access point is connected to Port 2 of the AS-P, which is configured for dual IP.
