1 Introduction
The BASRT-B is a multi-network router, sharing messages
among BACnet/IP, BACnet Ethernet and MS/TP networks. 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, gateway address and User ID/Password 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.
A BACnet Broadcast Management Device (BBMD) within the
router can be enabled to allow BACnet communication across
routed IP networks (ones with multiple IP subnets). If all IP devices
use the same subnet, this functionality can be left disabled. The
router also supports Foreign Device Registration.
