TD071200-0IC

1 Introduction

The BASRT-B routes messages between BACnet/IP and

BACnet MS/TP networks as per the ANSI/ASHRAE 135-2004

standard. It allows BACnet/IP devices operating over Ethernet to

communicate with MS/TP devices. 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 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. Through this port, up to 254

devices can be addressed —as many as 31 full-load devices on

the attached segment. All MS/TP baud rates (as stated in the

BACnet standard) 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 hook-up.

The BASRT-B features a user-accessible switch to reset the IP

address, subnet mask and gateway address to the factory defaults.

Three LEDs are present: A power LED glows green when proper

power 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.

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.

When using the BASRT-B to communicate on routed IP networks

(ones whichuse multiple IP subnets), a separate device with BBMD

functionality must be provided. If all IP devices use the same

subnet, then BBMD functionality is not required. For example, if

the BASRT-B uses IP address 192.168.1.1 and another BACnet/IP

device (which will communicate with the BASRT-B) uses 10.0.0.1,

then BBMD functionality is required from another device on your

network.

3 Power

The BASRT-B requires 24 VAC or 24 VDC (see Figure 6)

while drawing no more than 3 W 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

text on the following page carefully.

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.

TD071200-0IC

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 thesecondary 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.

Figure 7 —2-wire MS/TP Bus with Shared Power Source

TD071200-0IC

Figure 8 —3-wire MS/TP Bus with Shared Power Source

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.

TD071200-0IC

Figure 10 —3-wire MS/TP Bus with Separate Power Sources

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).

4 LEDS

Power glows green if power supplied to the unit is proper

Ethernet glows solid for a valid link (green for 100 Mbps or

yellow for 10 Mbps) and flashes to show activity

MS/TP flashes green when receiving valid MS/TP traffic
