ESCO-IPN
Portable BACnet Multi-Network Router
Installation Guide
1.0 INTRODUCTION
The information contained in this document provides details of installation,
and operation for installers and users of the ESCO-IPN multi-network
router.
ESCO-IPN 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 ESCO-IPN. No communications is
supported via the USB port.
The ESCO-IPN 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.

3.0 WIRING
The ESCO-IPN 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 ESCO-IPN does not apply any fail safe bias or
termination.

4.0 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 the local
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.
LED'S
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.

5.0 WEBPAGE CONFIGURATION
Each router contains an interactive web server, accessible from any Internet-
compatible PC on the local network. 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 ESCO-IPN,
a computer for configuration, and a connection to the MS/TP network. Make
sure that a USB cable connects between the PC and the ESCO-IPN 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 to show an IP address
for the PC of 192.168.92.69.
After entering the router’s IP address into your browser’s address field, you will

IMPORTANT
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.

Device Parameter
Device Instance (Default Value = 0)
The router’s device instance is a 22-bit value (0–4,194,302). Do not use
4,194,303 which is reserved by BACnet. Each BACnet device within the same
BACnet internetwork must have a unique device instance. One must be assigned
to the ESCO-IPN.
BACnet Ethernet
Ethernet Network (Default Value = 0 —disables BACnet Ethernet)
Most BACnet communication that is carried by Ethernet uses the BACnet/IP
protocol. However, there are still instances in which the older BACnet Ethernet
protocol (ISO 8802-3) is found. The ESCO-IPN allows these two protocols to
communicate.
BACnet Ethernet uses Ethernet MAC addresses for station addressing — unlike
BACnet/IP which addresses messages by means of Internet Protocol (IP)
addresses. Each Ethernet MAC address (often called the physical address) is
unique to the Ethernet network adapter. It is permanently embedded into the
adapter during manufacture and cannot be changed. It is composed of six two-
digit hexadecimal numbers (00–FF). An example of an Ethernet MAC address is:
00-08-A1-10-BD-EB
Each Ethernet network adapter has the ability to store an IP address that is
changeable. This IP address is typically represented as four decimal values (each
is 0–255) separated by dots. Often called the dotted quad format, an example is:
192.168.92.1
IMPORTANT
Although they may share the same Ethernet physical network, BACnet
Ethernet devices and BACnet/IP devices must have their own unique network
number and these two networks cannot communicate unless their messages
pass through a router. These network numbers must be in the range of
1–65534 (0 and 65535 are reserved). If the BACnet Ethernet network value is
left at its default value of 0, the BACnet Ethernet function within the ESCO-
IPN will be disabled. To prevent message loops, a subnet must have only one
router enabled for BACnet Ethernet.
BACnet/IP Parameters
BACnet/IP UDP Port (Default Value = 0xBAC0)
This 16-bit hex value (BAC0–BACF) is set to BAC0 by default. Usually, this
default value should not be changed. In a typical installation, each ESCO-IPN
will be assigned the same UDP port.
BACnet/IP Network (Default Value = 1)
The BACnet/IP network number is a 16-bit value (1–65534). Each network within
the BACnet internetwork must have a unique number. This includes the BACnet/
IP and MS/TP sides of the ESCO-IPN. Do not use addresses 0 or 65535 since
these addresses are reserved.
IP Address (Default Value = 192.168.92.68)
The IP address of the router can be 0.0.0.1–255.255.255.254. A private address is
usually assigned to the ESCO-IPN.
IP Subnet (Default Value = 24)
This value (0–30 in the “slash” notation) is the number of bits with a “1” in
the mask. The default value of 24 corresponds to 255.255.255.0 in the dotted
decimal format. All devices on the same subnet which communicate via BACnet/
IP should use the same subnet mask.
IP Gateway (Default Value = 192.168.92.1)
The default gateway for the IP stack is a dotted decimal number in the range of
0.0.0.0–255.255.255.254. This will be the IP address of your local IP router —if
one exists.
MS/TP Parameters
MS/TP MAC (Default Value = 00)
This is the 8-bit (0–127) MAC address of the router’s MS/TP port, in decimal.
Lower MAC address numbers are preferred with the default recommended. It is
further recommended that all other BACnet devices attached to the same MS/
TP network be assigned consecutive MAC addresses beginning with 1 without
allowing any gaps in addressing. Slave devices may have MAC addresses of
128–254, but MAC address 255 is reserved.
MS/TP Network (Default Value = 2001)
This 16-bit decimal network number (1–65534) must be unique for all BACnet
networks within the BACnet internetwork. No other networks, regardless of
type, can have the same network number. Do not use addresses 0 or 65535
since these addresses are reserved.
Max Masters (Default Value = 127)
Only master nodes participate in the MS/TP token-passing process. The highest
master MAC address (in decimal) in the MS/TP network is 127 and you should
use 127 if you are unsure of other MS/TP device addresses. Each MS/TP device
should use this same value. For a value in this field to be proper, it must equal
or exceed the highest MAC address for any master on the network. Optimum
performance occurs when this value:
1. Equals the highest MAC address of any master, and
2. All masters use sequential MAC addresses
Since many BACnet devices do not allow this parameter to be changed, leave
the ESCO-IPN at the default value.
Max Info Frames (Default Value = 40)
This is the maximum number of messages that can be routed onto the MS/
TP network by the router per token pass. Its range is 1–100, and typical values
are 20–40. Smaller values provide less access to the MS/TP network from the
BACnet/IP network because they give native MS/TP messages higher priority
than those passed by the router from BACnet/IP. The default value usually
provides good performance.
MS/TP Baud Rate (Default Value = 9600)
The baud rate of the MS/TP network can be 9600, 19200, 38400 or 76800 bps.
All MS/TP devices on the same MS/TP network must use the same baud rate.
On power up the router checks for other masters; if finding none, it begins token
passing — at which point autobauding devices will adjust to the router’s baud
rate.
MS/TPTolerance (Default Selection = Strict)
This setting determines the degree to which interoperability with devices is
successful. The Lenient option is less efficient for traffic flow but optimises
interoperability. A slight improvement in performance will be realised by
selecting the Strict setting.

Status Screen
The Status Screen depicted in Figure 10 reports the traffic of the various
protocols handled by the ESCO-IPN. It shows the number of messages received
and transmitted for each of the supported networks.
IMPORTANT
“BIP 1” is the only BACnet/IP port in use. Although it appears in the
screen, “BIP 2” is not used in this version of the product. Therefore, the counts
of “BIP 2 Incoming Packets” and “BIP 2 Outgoing packets” will always be 0.
“Available Memory” (at the bottom of the list) is the amount of RAM currently
unused (normally about 30K). If one network is temporarily offline and another
network is attempting to communicate with this network, the available memory
may drop very low until the offline network returns to an online condition.
The remaining information indicates the instantaneous MS/TP state of the
router and is documented in the MS/TP portion of the BACnet standard.
“RFSM” is the current Receive Frame State Machine state.
“MNSM” is the current Master Node State Machine state.
By refreshing this page, you can watch the router MS/TP state change and gain
insight into the state of the MS/TP network (as seen by the router). For example,
if “MNSM” always reports SoleMaster or PollForMaster, after repeated refreshes,
then the router cannot communicate with any MS/TP devices.
“Next Station” is the MS/TP MAC address of the device to which the router will
next pass the token. This value may change if devices leave or enter the network
— and when the router searches for devices on the network, as per the BACnet
MS/TP standard.
BIP 1 Incoming Packets = 440
BIP 1 Outgoing Packets = 440
BIP 2 Incoming Packets = 0
BIP 2 Outgoing Packets = 0
BACnet/Ethernet Incoming Packets = 0
BACnet/Ethernet Outgoing Packets = 1
