1.1 OVERVIEW
The MATRIX Router is a full-featured BACnet router that directs messages between MS/TP, BACnet/IP
(Annex J) and BACnet/Ethernet (8802-3) networks. Compliant to the BACnet standard (ASHRAE 135-
2004), the MATRIX Router provides users with the ability to directly monitor and control BACnet system
operations with or without an installed building controller solution.
Within the MATRIX Router product family, several variants exist in which one variant may provide
additional functionality over another. For example, MATRIX-BBO is a single port BACnet router without
BBMD capabilities that provides simple routing of BACnet packets for small, enclosed sites. Table 1-1
provides a breakout of all MATRIX BACnet Router products.

1.2 WHEN WOULD I USE AROUTER?
The MATRIX BACnet Router can be implemented in various ways, depending on your project
specification. The following section provides an explanation of the most common examples of how the
MATRIX BACnet Router would be incorporated.
1.2.1 TRADITIONAL OPERATOR WORKSTATION
In its most simple and basic form, a MATRIX BACnet Router is used to allow an operator workstation or
graphical user interface, such as Auto-Pilot or Integra V.A.C, to access networks consisting of MS/TP
devices Alternatively, if your operator workstation or graphical user interface can only be configured for
one layer type (e.g. BACnet/Ethernet only), the product can be used to route BACnet/Ethernet messages
to BACnet/IP.
Figure 1-1 Example of a Simple BACnet Network
In the example network sown above, a MATRIX BACnet Router serves as the intermediate connection
between an IP/Ethernet network, and the MS/TP network. Requests initiated from the BACnet/IP or
BACnet/Ethernet network will be forwarded to the BACnet MS/TP network. Visually, each BACnet MS/TP
device will appear as if it were physically connected to the WAN.

1.2.2 MULTI-VENDOR MS/TP INTEGRATION
A BACnet router is commonly used to third-party vendor BACnet MS/TP products. This approach allows
foe each vendor to communicate on their own physical network without disrupting communications on
another network that may contain another third-party vendor.
Although the BACnet standard defines specific characteristics for each communication layer, vendors are
permitted to implement optional features that could effect network bandwidth performance negatively. For
example, a manufacturer may not support specific MS/TP baud rates or implement slower timing
characteristics. For this reason, isolating vendors from one another using a BACnet router has become
common practice in multi-vendor installations.
Figure 1-2 Example of a BACnet Network with Third-Party Devices
In the example above, MATRIX BACnet Routers are used to isolate EIA-485 networks between different
manufacturers. When integrating with third-party MS/TP devices, American Auto-Matrix recommends
using a MATRIX BACnet Router to isolate vendors to their own communication bus. This practice will
greatly reduce the potential for communication issues.

1.2.3 MULTI-BUILDING COMMUNICATIONS
Many of the communication capabilities within BACnet/IP are dependent on the use of broadcast
messaging. In most IT networks, broadcast messages are blocked or forbidden.
To allow multiple BACnet/IP networks to communicate as flexibly as other traditional Ethernet protocols,
select MATRIX BACnet Routers can be configured to act as a BACnet Broadcast Messaging Device
(BBMD). A BBMD will take broadcast messages originating from one network and forward them onto other
defined networks that have a BBMD or MATRIX BACnet Router configured as a BBMD.
Figure 1-3 BACnet System Architecture with BBMD
In the example above, messages originating from the head-end or either control network using a MATRIX
BACnet router can be distributed throughout the entire system in a logical and straight-forward approach.
Providing BBMD capabilities within the MATRIX BACnet Router avoid possible network security issues in
an existing IT network.

PRODUCT OVERVIEW NETWORKING CONSIDERATIONS
MATRIX BACnet Router User Manual (6/6/2007) 1-7
1.3 NETWORKING CONSIDERATIONS
As the MATRIX BACnet router is compliant to the standards of ASHRAE/ANSI 135, there are
considerations that must be kept in mind when designing a BACnet inter-network using this product.
Following these simple guidelines will ensure project success.
1.3.1 MS/TP MEDIUM RULES
Specified by ASHRAE, an MS/TP network shall use shielded, twisted-pair cable with characteristic
impedance between 100 and 130 ohms. The maximum length of an MS/TP network is 4000 feet (1200
meters) using 18 AWG cabling. An MS/TP network shall have no “T” or “star” based network connections.
Networks requiring a longer distance may utilize an optically isolated repeater to extend this limit.
1.3.2 MS/TP NETWORK LOADING
The MATRIX BACnet Router, as well as American Auto-Matrix Native Series unitary controllers, use half-
watt serial driver technology. By law of electrical limitations, a serial network of half-watt devices may
consist of up to 64 devices total.
The MATRIX BACnet Router has been qualified to accept a network of up to 63 additional BACnet MS/TP
devices (router + 63 devices = 64 load limit). This qualification process included verifying electrical network
capacitance provisions, as well as optimal bandwidth speed.
While it may be possible to achieve more than the above mentioned limit using media converters and
repeaters, American Auto-Matrix discourages applications that exceed this limit. If you need to network
more devices as part of an MS/TP network, it is recommended that you purchase additional MATRIX
BACnet Router hardware.
