1 Introduction
The BASRTP-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 unit attaches
to a USB port of your computer and 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 signal polarity to whatever is
needed by the attached equipment. Thus, only a straight-through
CAT5 cable is needed for hook-up.
The USB port is strictly used to power the BASRTP-B. No
communications is supported via the USB port.
The BASRTP-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.

3 Power
The BASRTP-B features a USB 2.0 Full Speed Device Port that
accepts the USB cable with Type B plug that is included in the box. It
takes 5 VDC from a host computer, while typically drawing 300 mA of
current. It can operate from a USB hub, if desired, and no driver
installation is needed.
For MS/TP devices, see Figure 5 for proper 2-wire bus connections and
Figure 6 for proper 3-wire bus connections. The BASRTP-B does not
apply any failsafe bias or termination.

4 Operation
MS/TP Port
The MS/TP port uses an isolated EIA-485 transceiver that is
connected to both a removable 3-pin connector (Figure 1) and an
RJ-11 jack. Either connector can be used for the MS/TP line.
The EIA-485 transceiver’s + and – lines tie to + and –pins of
both connectors. The SC pin ties to the circuit ground of the
EIA-485 transceiver and is isolated from both the USB and
Ethernet ports.
The router can access 254 MS/TP devices and supports 31
devices on thelocal bus at rates of 9600, 19200, 38400, or 76800 bps.
Ethernet Port
This port offers a shielded RJ-45 connector. Through auto-
negotiation and Auto-MDIX, it automatically matches its duplex
setting, flow control, data rate and signal polarity to whatever is
needed by the attached equipment. Thus, the provided CAT5 cable
is the only cable needed for the Ethernet hook-up.
IP Address Reset Switch
When pressed for at least 1 second
(at any time the router is under
power), this switch will reset the
default values of the IP address
(192.168.92.68), gateway address
(192.168.92.1) and netmask (24).
It is accessed by a paper clip (or similar device) via a small hole
in the case —then after reboot, the default values apply.
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

5 Webpage Configuration
Each router contains an interactive web server, accessible from
any Internet-compatible PC on the local network and compatible
with recent versions of Internet Explorer (5.0 or later, suggested)
or Netscape Navigator (7.1 or later, required). It is factory-
programmed with a default IP address of 192.168.92.68 and a
Class C subnet mask of 255.255.255.0 (/24).
Figure 8 shows the setup for accessing the MS/TP network using
the BASRTP-B, a computer for configuration, and a connection
to the MS/TP network. Make sure that a USB cable connects
between the PC and the BASRTP-B so it can be powered.
To configure the router, attach it to a computer with an Ethernet
connection and a standard web browser. For initial configuration,
the PC chosen for the procedure should temporarily have its IP
address modified as illustrated in Figure 9 —which employs a
Windows®XP example.
The example in Figure 9 suggests an IP address for the PC of
192.168.92.69, but the final quad of the address could be any
value from 3 to 254 —except for 68 which is used by the router.
After the IP address of the PC has been set to the same subnet as
the router, a browser can access the router via its default IP address.
