Installing and Configuring the BACnet®/IP Router

Ordering number: 4950 0471 (ARCNET), 4950 0472 (Ethernet)

This document describes the installation and
configuration of the BACnet/IP Router. The router
enables you to connect two BACnet local area
networks (LANs) to create a BACnet inter-network.
The LANs may be either BACnet/IP Ethernet or
BACnet ARCNET®.

Before you begin

Before wiring or configuring the router, get the
TCP/IP information from the network administrator
for the site. Figure 1 on page 2 shows a sample letter
of request. Ensure that the TCP/IP information
includes: IP address, subnet mask, default gateway,
and

user datagram protocol (UDP) port

In addition to the TCP/IP information, you may also
need the following information to help with the
network system setup:

• Capability of enabling and disabling a BACnet
broadcast messaging device (BBMD)

• IP addresses of remote BBMDs, routers, and
gateways in the TCP/IP networks

• BACnet network numbers for each of the direct
LAN interfaces

• Information about the LAN to which the router
will be connected, such as other devices connected
to it: BACnet routers, BBMDs, TCP/IP routers,
gateways, switches, and hubs

Note:

Since the router holds configuration information
indefinitely, you can configure the router before
travelling to the site.

For more information about BACnet/IP network
installations, see engineering bulletin Tracer
Summit® BACnet/IP Network Installations (BAS­PRB004-EN).

When you have the TCP/IP information, refer to the
topics that follow. The topics provide router
specifications and wiring information. They also
provide information and procedures for connecting,
configuring, and troubleshooting the router.

Wire the router

When wiring the router and the hub to the Ethernet
LAN, use any combination of straight (patch) cables
and crossover category (CAT) 5 cables. Using CAT 5
cables enables you to connect other devices, such as
a BMTW building control unit (BCU) to the LAN.
Use straight cables when there is a hub; use
crossover cables when there is no hub.
Figure 2 on page 3 shows a router connected to a
typical LAN topology.

Note:

If you are using coax cable, prior to wiring the
router, verify that each LAN cable is terminated
with the appropriate resistor. Ethernet RG58 coax
cable needs a 50 ohm resistor. ARCNET RG62 coax
cable needs a 93 ohm resistor.

To wire the configuration shown in
Figure 2 on page 3:

Subject:

As part of the upcoming facility renovation project, Trane has been
selected to provide the new facility-wide Building Automation System. This
system will control heating, air conditioning, and ventilation in the facility to
provide increased comfort and decreased utility costs. The Trane system
selected is called Tracer Summit.

The Tracer Summit system consists of a series of embedded controllers,
called Building Control Units (BCUs), and PC Workstations. The BCUs
control the equipment in the facility, and the PC Workstations are used for
system configuration and operation. As part of the construction
specifications, Trane is required to use the TCP/IP network for
communications.

Tracer Summit communications use the BACnet protocol (ASHRAE/ANSI
135-95), and IP communications follow annex J-1999 of this standard.

The critical networking requirements are:

IP communications using UDP at port 47808 or other user-designated

•

port.

Each BCU must have a permanently assigned IP address, subnet

•

mask, and gateway address.

PC Workstations can have a permanently assigned IP address or use

•

DHCP.

If you choose to allow access from the Internet, the firewall must allow

•

UDP at the designated port and expose the IP addresses of the BCUs
(i.e. NAT not enabled on these devices).

Dialup communications supported either via IP Dialup (PPP) to your

•

intranet (provided by others), or directly to any BCU using Tracer
Summit workstation software.

This allows for easy operation on your corporate intranet. Any point of
access to the intranet can be used to connect to the Tracer Summit
system.

Tracer Summit System Installation

For installation of the Tracer Summit system, we need network jacks
(10BaseT) in the Mechanical rooms in the Northeast corner of the first
through fourth floors of your facility. We also need the following
information for each Mechanical room:

Location IP

Floor 1

Floor 2

Floor 3

Floor 4

UDP port: __________

We will also be installing the Tracer Summit Windows 95/98/2000/NT 4.0­compatible software on the PC workstation located on the Facility
Manager’s desk. This PC will need to be set up for IP communications by
your staff, using either a permanently assigned IP address or DHCP.

When you have the above information, please send it to me at EMAIL
ADD RES S, or fa x this pa ge to m e at F AX N UMB ER. If you ha ve an y
questions or concerns, please call me at [phone].

I am looking forward to working with you on this project.

Thanks again,

Note:

If the router has two Ethernet cards, the ports
are labeled with the interface number for each
card (refer to factory configuration document).

2. Using a straight CAT 5 cable, connect the hub to
the bottom RJ-45 port on the router
(Figure 3 on page 3).

3. Using a crossover CAT 5 cable, connect the
10Base2 Ethernet port to the BMTS BCU
Ethernet port.

Note:

The router cannot start without the onboard
Ethernet connected.

4. Connect the supplied ac power cable to both the
router and an ac power source.

3270 3319 Rev B 2

Note:

There is no power switch. When the router is
connected to both an IP Ethernet LAN and a
power source, the router turns on.

▲

IMPORTANT

Do not plug an active ARCNET cable into the
onboard Ethernet port. Electrical incompatibilities
between the two network types may cause the
Ethernet port to be permanently damaged.

Note:

If an ARCNET cable is disconnected during
router operation, the router buffers the packets
that are destined for the ARCNET network as
long as possible. When all buffers are full, the
router automatically reboots.
