1 Introduction
The BASrouter provides stand-alone routing between BACnet networks such as BACnet/IP,
BACnet Ethernet, and BACnet MS/TP – thereby allowing the system integrator to mix BACnet
network technologies within a single BACnet internetwork. The router is configurable via its
internal webpage.
The BASRT-B comes in a metal case, is DIN-rail mounted and is powered from a 24 VAC/VDC
source. It has one optically isolated MS/TP port and one 10/100 Mbps Ethernet Auto-MDIX port.
The MS/TP port offers a 3-pin terminal block with a removable plug for the EIA-485 connection.
Up to 254 master and slave devices can be addressed through this port — however, the attached
segment can accommodate up to 31 full-load devices. MS/TP baud rates: 9600, 19200, 38400,
and 76800 are supported.
The Ethernet port offers a shielded RJ-45 connector. Through auto-negotiation and Auto-
MDIX, it automatically matches its duplex setting, data rate and communication pair usage to
whatever is needed by the attached equipment. Thus, only a straight-through CAT5 cable is
needed for connection.
When enabled from the web page, a DHCP client feature allows the BASrouter to obtain an IP
address from a DHCP server on the network automatically. FIXED IP address is the default
setting. DHCP setting should be used with caution when BBMD and FDR are enabled because
of the dynamic IP addressing nature of the DHCP protocol. If you are unsure use FIXED IP
setting.
The BASrouter features a user-accessible momentary switch to reset the IP address, subnet
mask, gateway address, and User ID/Password to the factory defaults.
Three LEDs are present: A power LED glows green when proper power connection is provided.
The Ethernet LED glows green for 100 Mbps operation and yellow for 10 Mbps and flashes to
indicate activity. A green LED flashes when MS/TP traffic is received. If the MS/TP LED is off, but
the BASrouter is powered and connected to a MS/TP network, could be an indicator that the
BACnet MS/TP network is down.
Each unit complies with Class A radiated and conducted emissions as defined by EN55022 and
CFR 47, Part 15, and is intended for use in non-residential areas.
A BACnet Broadcast Management Device (BBMD) within the router can be enabled to allow
BACnet communication across routed IP networks, that is a network comprised of multiple IP
subnets. If all IP devices use the same subnet, this functionality can be left disabled. The router
also supports Foreign Device Registration.
Attention: Be cautious when using BBMD and FDR in conjunction with DHCP IP addressing.
Depending on your DHCP server settings, obtained IP address may change. If you are unsure,
use FIXED IP addressing in the BASrouter.

3 Power
The BASRT-B requires 24 VAC or 24 VDC (see Figure 6) while drawing no more than 4 VA of
power. The recommended conductor size is 16–18 AWG. COM is directly connected to zero
volts and the chassis is DC isolated from zero volts. Input connections are reverse-polarity
protected.
Figure 6 — Power Options
WARNING: Powering devices can present hazards. Read the following text carefully.
3.1 POWER SUPPLY PRECAUTIONS
Internally, the router utilizes a half-wave rectifier and therefore can share the same AC power
source with other half-wave rectified devices. Sharing a common DC power source is also
possible. Sharing AC power with full-wave rectified devices is NOT recommended. Full-wave
rectified devices usually require a dedicated AC power source that has a secondary elevated
above ground. Both secondary connections are considered HOT.
AC power sources that power several half-wave devices have a common secondary connection
called either COMMON, LO, or GROUND. This connection might be tied to frame ground or
earth. The other side of the secondary is considered the HOT or HI side of the connection.
Connect the HOT side of the secondary to either the HI or the HIB input on the router and the
LO side to COM on the router. All other half-wave devices sharing the same AC power source
need to follow the same convention. When using a DC power source, connect the positive
terminal of the source to either the HI or the HIB input and the negative terminal to COM on the
router. Reversing polarity to the router will not damage the router. If shielded cable is used, it is
recommended to tie all shield segments together and connect one of the shield ends to chassis
while taping back the other.
For MS/TP devices that share a power source with the BASRT-B, see Figure 7 for proper 2-wire
bus connections and Figure 8 for proper 3-wire bus connections.

WARNING: Devices powered from a common AC source could be damaged if a mix of half-
wave and full-wave rectified devices exist. If you are not sure of the type of rectifier used by
another device, do not share the AC source with it.

For MS/TP devices that use a power source separate from the BASRT-B, see Figure 9 for
proper 2-wire bus connections and Figure 10 for proper 3-wire bus connections.
Figure 9 — 2-wire MS/TP Bus with Separate Power Sources
Figure 10 — 3-wire MS/TP Bus with Separate Power Sources
3.2 Limited Power Sources
The router should be powered by a limited power source complying with the requirements of the
National Electric Code (NEC) article 725 or other international codes meeting the same intent of
limiting the amount of power of the source. Under NEC article 725, a Class 2 circuit is that
portion of the wiring system between the load side of a Class 2 power source and the connected
equipment. For AC or DC voltages up to 30 volts, the power rating of a Class 2 power source is
limited to 100 VA. The transformer or power supply complying with the Class 2 rating must carry
a corresponding listing from a regulatory agency such as Underwriters Laboratories (UL).
