BASrouterLX

High-Performance BACnet® Router

INSTALLATION GUIDE

INTRODUCTION

The BASrouterLX is a high-performance BACnet router providing stand-alone
routing between BACnet networks such as BACnet/IP, BACnet Ethernet, and
BACnet MS/TP. Besides its high-speed processor, it has advanced features such
as MS/TP slave proxy support (allowing auto-discovery of MS/TP slaves) and
MS/TP frame capture and storage for use with Wireshark®. Up to 50 BBMD
entries can be made. The BASrouterLX has two physical communication ports
— a 10/100 Mbps BACnet/IP Ethernet port and an optically isolated EIA-485 port
for MS/TP. A USB port is included for future use. Router configuration is
accomplished via a web page

POWER

The BASrouterLX requires 24 VAC or 24 VDC and draws a commensurate
amount of current. 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 5 — Power Options

WARNING: Powering devices can present hazards. Read the following carefully.
Since the product incorporates a half-wave rectifier circuit, it can share the same

24 VAC power with other half-wave rectified devices. It can also be powered
from a 24 VDC source. A redundant power connection exists for back-up power
schemes.

The product incorporates a 3-wire optically-isolated EIA-485 interface for the
serial connection, allowing better circuit protection and noise immunity. To
connect to other 3-wire devices simply make a one-to-one connection to the other
devices. But when connecting to 2-wire non-isolated devices, the signal common
(SC) on the product must share the reference used by the 2-wire devices. This is
accomplished by tying the SC pin to COM on the product and by grounding the
low-side of each power supply on all connected devices. In this way all EIA-485
transceivers share the same earth reference. Notice that the SC pin is signal
common and not a shield pin. For shield connections, use the SH pin. Far-end
external termination is required as shown. Near-end bias and termination are
internally supplied within the product.

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).

LEDS

Power This LED is green if power supplied to the unit is proper.
Ethernet L glows green for a proper 100 Mbps link and yellow for a proper 10

Mbps link. It flashes to show activity.

D glows green for a full-duplex link and is off for a half-duplex link
EIA-485 Tx flashes green when transmitting valid EIA-485 traffic.

Rx flashes green when receiving valid EIA-485 traffic.

RESET SWITCH

To reset the router to its default values (except for configuration settings), use a
paperclip or similar tool to press the Reset IP button for at least 3 seconds while
the router is powered. Then release the reset button and remove power from the
router for 3 seconds. Restore power and the unit will now use default IP values
and User ID/Password which are admin/admin.

CABLING CONSIDERATIONS

When attaching cables to the unit, Table 1 should be considered.

Table 1 — Cabling Considerations

TD120100-0IC

NOTE: If using shielded cable, connect to chassis at only one point. Wire size

may be dictated by electrical codes for the area where the equipment is being
installed. Consult local regulations.

Observe in Table 1 that 10BASE-T segments can successfully use Category 3, 4
or 5 cable — however, 100BASE-TX segments must use Category 5 cable.
Category 5e cable is highly recommended as the minimum for new installations.

The Ethernet port of the router employs Auto-MDIX technology so either straight­through or crossover cables can be used to connect to the network.

MS/TP PORT

This port uses an isolated EIA-485 transceiver connected to a 5-pin removable
connector. The transceiver + and – lines tie to + and – pins of the connector. The
SC pin ties to the transceiver ground. You MUST connect the SC pin to the
MS/TP segment signal common — or EIA-485 communication will fail!

In Figure 10 a simplified schematic of the isolated EIA-485 transceiver is shown.
Notice that the transceiver common (SC) is electrically isolated from the router
power supply common (COM) through the use of opto-isolators and an isolated
DC-DC converter. An isolated EIA-485 transceiver offers less chance of damage
to the transceiver from high common-mode voltages, but there is still a risk. Surge
suppression is applied between the two differential inputs and between each input
and ground. Since the transceiver is electrically isolated, the transceiver circuit
common must be brought out for connection to the other devices on the EIA-485
network. This is accomplished by pin SC. The differential pair is labelled + and
– and requires a three-wire connection to the EIA-485 network. Connecting other
isolated EIA-485 devices is no problem since each device requires a 3-wire
connection. Just make corresponding connections. For non-isolated EIA-485
devices, usually only a 2-wire connection is provided. The third wire is the power
supply common. In this situation, the SC connection MUST be made to the power
supply common of the non-isolated device. Refer to the device vendor
instructions for connecting such a device.

In an application where one connection is made to Ethernet and the other to EIA­485, the location of the router is probably at the end of the EIA-485 bus segment
and therefore both bias and termination must be applied to the segment end. The
product is shipped with bias and termination applied, but this can be changed by
removing three jumpers. This should be done if the router is to be connected
anywhere between the end EIA-485 devices.

The router can address up to 31 MS/TP full-load or 62 half-load devices on the
local bus at baud rates from 9.6 to 115.2 kbps.

EIA-485 Bias and Termination Jumpers

TD120100-0IC

10

After removing the router cover, three jumpers are accessible on a 6-pin jumper
block located near the EIA-485 connector. These impart 604 Ω of bias via the upper
jumper (pull-up) and the lower jumper (pull-down), and 130 Ω of termination
impedance with the middle jumper. With all three jumpers in place, the effective
termination resistance is 120 Ω — consistent with the MS/TP standard. If the
router is not installed at the end of a segment, remove all the jumpers and install
120 Ω at each far end of the bus.
