MultiHop Ethernet Data Radio Overview
The MultiHop Ethernet Data Radio system provides extremely reliable communication in large plants, over long distances,
or through difficult terrain. A network can easily cover many square miles and has a raw bit rate of 300Kbps.
Master, Repeater, and Slave Radios
All radios can be configured as a master, repeater, or slave radio.
Master Radio: Every network has only one master radio and all data is routed to or from the master. Because of this, the
network will have better throughput if the master radio is connected to the PLC or HMI that generates the most data
traffic.
Repeater Radio: Repeater radios are slaves that also repeat. Although it is possible to use many repeaters in a network,
it is usually better to carefully define only a few devices as repeaters to help the network form faster and result in fewer
repeated messages. Repeating a message many times unnecessarily slows down the network. Repeater radios should be
stationary and always on; a moving or powered off repeater causes a slight delay in communications while the network
reforms through other repeaters.

SureCross MultiHop Ethernet Data Radio
Slave Radios: Slave radios cannot repeat and are used at the endpoints of the network. Mobile radios and radios that
may not always be on while the network is in use should be configured as slave radios to prevent other devices from
attempting to connect through them to the master.
Topology
The MultiHop Ethernet data radio may operate in either star topology mode or in MultiHop topology mode.
Star Topology
2
3
1

At the center of the wireless star topology is the master
radio. All wireless traffic is managed by the master and
messages can only be sent to or from the master. If a data
packet needs to get from one slave to another slave it is
routed through the master. In a star topology network, the
master radio is the parent and all slave radios are the
children.
For the simple example star topology network shown, the
following relationships exist:
• Radio 1 is the Ethernet master radio.
• Radios 2 through 6 are the Ethernet slave radios.

MultiHop Topology

MultiHop networks are similar to star networks but use
repeaters, which relay or repeat wireless messages The
MultiHop networks are self forming. The master will first
establish a wireless connection to every device within
range. Then repeaters establish wireless connections to
repeaters and slaves further away from the master. The
network will self-heal: if a repeater is lost, slaves
automatically attempt to reconnect to the master through
other repeaters. The advantage of using repeaters is that
you can reach very long distances and "hop" over obstacles
like buildings or hills. The disadvantage to using repeaters
is that repeating takes time. Adding a repeater doubles the
wireless range but also doubles the time it takes to
communicate.
In MultiHop networks, the master radio is the parent to all
devices connected to it. Repeater radios are also parents to
radios below them. A parent may have many children, but a
child has only one parent.
For the simple example MultiHop network shown, the following relationships exist:
• Radio 1 is the master radio within the MultiHop Ethernet data radio network.
• Radios 2 and 4 are repeater radios.
• Radio 2 acts as a parent radio to radios 3 and 4, but is the child of radio 1.
• Radio 3 is an slave radio. Its parent is radio 2 and, as a slave radio, cannot have any children radios.
• Radio 4's parent radio is radio 2 and its children are radios 5 and 6.
Which Topology is Better?
Star topology is faster and simpler. Use a star topology when all devices are easily within range. MultiHop networks are
more capable and flexible. Use a MultiHop network for more challenging terrain, longer ranges, or where future additions
to the network may require a repeater.

SureCross MultiHop Ethernet Data Radio
Network Size and Throughput
Both the star and MultiHop radio network can support up to a total of 100 radios. However, desired throughput limits your
network's size. All radios in a network share the network's bandwidth, or total throughput. Doubling the number of radios
reduces by half each radio's available data throughput. For wireless systems, it is important to limit data traffic on the
ethernet wire to the minimum amount needed. One approach to increase the network size without lowering throughput is
to collocate another network. It is possible to install multiple networks in the same physical area.
Setting Up Your MultiHop Ethernet Data Radio Network
Banner Engineering recommends configuring and binding your wireless network before deploying the network in the field.
Step 1: Set the rotary dials
Set the left and right rotary dials each to 0.
Step 2: Set the Hardware DIP Switches
Refer to the DIP switch configuration section for complete definitions of all DIP switches. By default, all DIP switches are in
the ON position.
Configuring for a star topology
1. Define the master radio using DIP switch 4 in
the OFF position. Only one radio in the network
can be the master (server) radio.
2. Define the network topology on the master radio
using DIP switch 5. By default (ON), the star
topology is selected.
3. All remaining radios are slave radios, with DIP
switches 4 and 5 in the ON position.
OR Configuring for a MultiHop topology
1. Define one radio as the master radio, using DIP
switch 4 in the OFF position. Only one radio in the
wireless network can be the master (server) radio.
2. Define the network topology on the master radio
using DIP switch 5. To select MultiHop operation,
DIP switch 5 should be in the OFF position on the
master radio.
3. For all slave and repeater radios, DIP switch 4
should be in the ON position.
4. For repeater radios, move DIP switch 5 to OFF.
Step 3: Install the Wiring Terminal Header
Your MultiHop Ethernet Data Radio shipped with a small terminal header, part number 26732 (model BWA-HW-044). Plug
this terminal header into the terminals on the right side of the data radio.
Step 4: Connect 10-30V dc Power
Wire your 10-30V dc power to the Ethernet Data Radio using wiring connection 9. For low power operation, see Low Power
Operation in the Additional Information section.
Step 5: Bind Your Radios
To form the wireless network, bind all the slave radios to the designated master radio. Binding slave radios to their master
radio ensures the slaves only exchange data with that master. After a slave radio is bound, the slave accepts data only
from the master to which it is bound.
To bind the slave radios to the master radio, position the radios at least six feet away from each other to ensure good
communications, then follow these steps.
1. On the master radio: triple click button 2 to enter binding mode. The red LEDs flash alternately when the master is
in binding mode. Any slave entering binding mode will bind to this master.
2. On the slave radio: triple click button 2 to enter binding mode. The slave radio enters binding mode and locates the
master that is also in binding mode. The red LEDs flash alternately. After the slave is bound, the LEDs are both
solid red for a few seconds. The slave automatically exits binding mode, cycles power, and enters RUN mode.
3. Repeat the previous step for all slave radios that are to be bound to this master radio.
4. On the master radio: single click either button 1 or button 2 to exit binding mode and cycle power.
After all devices exit binding mode, allow a few seconds for all devices to be in sync with the Master device. The master
device green LED always blinks and the slave/repeater device LED blinks green when it is synchronized to the master
device.

Step 6: Perform a Site Survey
After placing your radios in the network locations, but before permanently installing them, perform a Site Survey to
analyze the radio signal strength of your chosen location. For details about Site Survey and how to run one, refer to
Conducting a Site Survey, located in the Additional Information section of this datasheet.
Step 7: Connect the Ethernet Data Radios
Connect an ethernet cable to the ethernet port on each radio. Many radio systems require you to set the IP address of the
radios themselves. This is not necessary for Banner's MultiHop Ethernet Data Radios; they will transmit data regardless of
their IP address. The amber LED 2 flashes when data is transmitting.
Note: If you have trouble getting the system to work here are a few tips:
1. Before installing the radios, verify the ethernet system works using an ethernet cable. Many problems with
ethernet are a result of improperly configured IP addresses.
2. Limit the data traffic. These long range radios do not have unlimited bandwidth. Verify the radios are properly
configured and bound by testing on a lightly used ethernet network.
3. View the internal web page of the master radio. Although it is not necessary to set an IP address on the Banner
radios, you may want to when troubleshooting problems. The master radio has an internal web page with
diagnostic information. By default, the internal web page is at 192.168.17.17. To access this page you must
connect the master radio to your PC and use a web browser. Login: root. Password: sxi.

Ethernet or Serial Mode. These radios operate in either ethernet or serial mode. In ethernet mode the radios route
ethernet data packets from their source to their final destination. Packets are routed by their IP address, making ethernet
systems efficient in Multihop mode and with many radios.

SureCross MultiHop Ethernet Data Radio
Because serial protocols are different, it is not practical to route packets with some configurations of radio devices. As a
result, the factory default setting is to broadcast all data between the radios when the radios are set to operate in serial
mode. For two-device radio systems configured in serial mode, it is possible to force routing between them by setting the
rotary dials on both radios to 01 to create routed messaging between two radios.
Radio Speed 300/200 kbps. A speed of 300 kbps (default) is recommended for most applications. Operating at 200
kbps provides more gain and can be an option in very long range applications.
Master Multihop or Star. Use a star topology when all devices are easily within range. Use the MultiHop topology when
the wireless network may require a repeater radio.
Repeater or Slave. Most radios in a network are slave radios. Careful selection of repeaters helps the network form up
with as few as possible wireless hops. Minimizing hops increases overall throughput.
RS-232 or RS-485. This setting selects the serial physical layer. Note that the physical layer does not need to be the
same on all radios in a network. In this way, the wireless network can be used to convert from RS-485 to RS-232.

-DEST. Destination Address. To force message routing when operating in transparent mode, set a specific destination
address.
-FMPCT. Formation percentage, default value of 50%. This device will not form a parent/child relationship with a parent
radio that misses more than 50% of the timing beacons (approximately a 25% site survey link value). If the only option
for a child is a parent with a less than a 25% site survey link value, change this value.
Conduct a Site Survey
A site survey analyzes the radio signal between a MultiHop child radio and its parent and reports the number of data
packets missed or received at relative signal strengths.
Conduct a MultiHop Site Survey (from the LCD Menu System)
Perform the site survey before permanently installing your network to pre-screen a site for its radio communication
potential, compare link quality in different locations in a factory, or assist with final antenna placement and aiming.
Site surveys can be conducted from either the master, repeater, or slave radios. A master radio is always a parent and the
slave radios are always children radios within the radio communication relationship. A repeater radio, however, may be
both a child radio to the master or another repeater and a parent radio to other repeater or slave radios. For a more
detailed description of the parent-child relationships, refer to the device data sheets.

SureCross MultiHop Ethernet Data Radio
Other radios bound within the same network remain synchronized to the network, but are blocked from sending data while
the site survey is running. The site survey analyzes the signal strength between the selected child and its parent radio
only. Disable site survey on one radio before initiating it from another.
Radios in site survey mode have a solid green LED for the duration of the site survey and the LCD display scrolls the
results. Because the statistics represent the lesser of the round-trip results, one person can ascertain the link quality from
either device.
Single-click button 2 to pause or resume autoscrolling the site survey results. While paused, button 1 single-step advances
through the four signal strength categories: green, yellow, red, and missed. Double-click button 2 to exit the results
display. (Refer to the data sheet for the menu structure.)
1. On a MultiHop radio, press button 1 until the display reads *SITE.
When the site survey runs, serial and I/O data radio communication between that parent and its children stops.
2. Single-click button 2 to enter the Site Survey menu.
Master radio: The displays reads CHLDRN. Repeater radio: The display reads PARENT. Slave radio: The display reads
PARENT.
3. Select the MultiHop radio to analyze.

radio
Single-click button 2 to display PARENT. Single-click button 2 to begin the site survey.
The site survey begins. LED 2 on both the parent and child radios flash for every received RF packet. To indicate the
parent is in site survey mode, LED 1 is a solid green. The data radio analyzes the quality of the signal between the
parent and child by counting the number of data packets received and measuring the signal strength (green, yellow,
and red).
4. Examine reception readings (G, Y, R, M) of the devices at various locations. M displays the percent of missed packets
while G, Y, and R display the percent of received packets at those signal strengths. These values are continuously
updated as long as the site survey is running.
GRN = GREEN excellent signal strength; YEL = YELLOW good signal strength; RED = RED marginal signal strength;
MIS = Percentage of missed packets. When possible, install all devices to optimize the percentage of YELLOW and
GREEN data packets received.
5. While the site survey is in process, single-click button 2 to pause or resume autoscrolling the site survey results. While
paused, button 1 single-step advances through the four signal strength categories: green, yellow, red, and missed.
Double-click button 2 to exit the results display.
6. Double-click button 2 on either the child or the parent device.
Site survey ends and the devices automatically resume operation.
Configuring the Ethernet Radio Using the Web Tool
The Ethernet Data Radio is typically configured using the hardware DIP switches on the side of the device. It is not
necessary to access the software configuration to create a Ethernet wireless network.
To configure your MultiHop Ethernet Radio:
1. Connect the radio to your computer's Ethernet port.
2. Launch an Internet browser.
3. Go to the Ethernet IP address: 192.168.17.17. This is the default IP address of the Ethernet Data Radio. Your
Ethernet Data Radio's IP address also displays on the LCD under the *DINFO menu (see menu system diagram).
Your computer's Ethernet connection parameters must be set to communicate with this IP address. For more
information about how to configure your computer's IP address, refer to document 133116.
4. Login in as "root" with a password of "sxi".
The configuration page loads to your Web browser.

SureCross MultiHop Ethernet Data Radio
Click Reset the Device to reboot the Ethernet Data Radio. To restore factory default settings, use the button on the
wiring board (see Wiring Connections).
Select Enter Programming Mode to update the firmware of the radio. To override the DIP switch settings, select
something other than Hardware. After selecting this option, the device becomes unresponsive: the LEDs stop flashing and
the device drops out of the wireless network until programming is complete or the power is cycled for the device.
Options under the Ethernet Radio heading allow you to select between operating your wireless network as either a star
network or a MultiHop network. After making any changes in this section, click the Save button to save your changes to
the radio.
Hardware/Master/Slave: Select Hardware to use the DIP switch settings. Select Master to override the DIP switches
and make this device a master (either the master of a star network or the master of a MultiHop network.) Select Slave to
make this devices either a star slave, MultiHop repeater, or MultiHop slave.
Master Broadcast Only: Factory default setting is OFF (not selected). When Master Broadcast Only mode is selected, the
internal wireless routing table on the master device is ignored. All master radio messages are transmitted to all wireless
devices in the network; messages originating in slave/repeater devices are routed back to the master device. Using Master
Broadcast Only results in lower throughput and messages are not acknowledged, making them less reliable.
Suppress Master Re-broadcast: Factory default setting is OFF (not selected). When not selected, the master device
automatically re-broadcasts radio messages coming in from radio devices back out the radio network when the destination
address is not known. This affects slave/repeater messages coming to the master that are unknown point to point
messages and all broadcast type messages. This allows for slave/repeater devices to send messages to other slave/
repeater devices within the wireless network. If all messages originate from Ethernet devices connected to the master
wireless device or when a wireless network only has a master and slave device (one-to-one networks), this feature can be
selected, suppressing re-broadcast messaging. In most cases this switch will have little to no affect on performance.

SureCross MultiHop Ethernet Data Radio
Master Re-broadcast Multicast: Factory default setting is OFF (not selected). With this feature off, the master wireless
device does not re-broadcast Multicast messages received from radio devices out to the radio network. Multicast messages
are found in certain protocols such as EtherNet/IP. To create a network with multiple end devices that want to use
multicast messaging to communicate, enable this feature. The performance is decreased when using this feature.
Optimize the wireless network operation by connecting Ethernet devices that create (produce) multicast messages to
slave/repeater devices.
When the device is a master: By default, the Ethernet Data Radio is set, from the master radio, to operate as a star
network. Only the master radio selects when the network is in star configuration and when it is in MultiHop configuration.
When the device is a slave: When the device is a slave radio, select slave operation or repeater operation. If the
network operates as a star network, only the slave configuration is recognized. Only MultiHop networks use repeater
radios.
Use the Network section to change the IP address if needed. If you change the IP address, carefully make note of the
new address, then cycle power to the radio to activate the new IP address. To reset the IP address to its factory default
settings, press and hold down the reset button on the ethernet board (see Wiring Connections section) for ten seconds.
The Device section displays the Ethernet Radio model number, serial number, version number, and uptime setting. When
calling the factory for technical assistance, have this information available.
The Ethernet Statistics section displays the number received and transmitted Ethernet packets and indicates if any
receive or transmit errors have occurred.

SureCross MultiHop Ethernet Data Radio
The Radio Statistics section displays the number of received and transmitted wireless packets.
Technical Note: Using the MultiHop Ethernet Data Radio with an EtherNet/IP®
or Modbus RTU System
The MultiHop Ethernet Data Radio is designed specifically to send small amounts of data very long distances. This long
range comes at the expense of throughput, requiring you to slow down data throughput significantly compared to other
wireless short range systems. When using the Ethernet data radio to replace an ethernet cable, some timing parameters
need to be relaxed on the EtherNet/IP or Modbus/TCP host system and unnecessary ethernet traffic limited.
•
•
EtherNet/IP systems have a requested packet interval (RPI); the maximum allowable RPI is 3200 milliseconds.
Modbus/TCP systems have a timeout.
Star Topology Mode
The time to transmit data in star mode is 150 milliseconds per 60 registers (120 bytes) over an EtherNet/IP or Modbus
TCP/IP connection.
The absolute minimum requested packet interval (RPI) for a simple, one hop system is 100 milliseconds for 60 registers
(120 bytes) over an EtherNet/IP or Modbus TCP/IP connection. Do not set the RPI faster than 100 milliseconds.
Example 1 - Using an EtherNet/IP host system and four remote devices
Each remote device has an input and output assembly connection of 60 registers or less, for a total of 4 × 2 = 8
connections. Set the EtherNet/IP's host system RPI to a minimum of 8 × 150 milliseconds, or 1,200 milliseconds.

SureCross MultiHop Ethernet Data Radio
Example 2 - Using one remote device to provide 1,000 registers of input data
A connection consisting of 1000 registers of input data will take 17 radio transmissions to send all the registers (1000 ÷
60 = 17), requiring 17 × 150 milliseconds = 2,250 milliseconds. Because this device also has an output connection of
six registers that requires an additional 150 milliseconds, set the RPI to 2400 or higher.
MultiHop Topology Mode
When using the Ethernet Data Radio in MultiHop mode with a repeater, the time required to transmit is doubled and the
RPI for each connection becomes 300 milliseconds per 60 registers. The RPI increases another 150 milliseconds for each
additional repeater in the data path.
Important Timing Considerations
• Good radio links transmit faster than poor radio links. Missed packets are retried, which consumes bandwidth.
• All data is routed through the radio master; the network will be faster when the master radio is connected to the
PLC.
• Each wireless hop slows down the network.
• Use unicast messaging; multicast messaging causes unnecessary additional traffic on the network.
• The previous examples are for the standard data rate of 300 Kbps. Proportionally increase the RPI at 200Kbps
Warnings
