Compliance General
The Aprisa SRi radio predominantly operates within frequency bands that are covered under a class license
or general user license which is a license is issued to ‘every person’.
Changes or modifications not approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Equipment authorizations sought by 4RF are based on the Aprisa SRi radio equipment being installed at a
fixed restricted access location and operated in point-to-multipoint or point-to-point mode within the
environmental profile defined by EN 300 019, Class 3.4. Operation outside these criteria may invalidate
the authorizations and / or license conditions.
The term ‘Radio’ with reference to the Aprisa SRi User Manual, is a generic term for one end station of a
point-to-multipoint Aprisa SRi network and does not confer any rights to connect to any public network or
to operate the equipment within any territory.

About the Radio
The 4RF Aprisa SRi Radio
The 4RF Aprisa SRi is a Point-To-Multipoint (PMP) digital radio providing 915 MHz Industrial Licence Free
Spread Spectrum communications.
The radios carry a combination of serial data and Ethernet data between the base station and remote
stations.
A single Aprisa SRi is configurable as a Point-To-Multipoint base station or remote station.
Aprisa SRi User Manual 1.0.0
18 | About the Radio
Product Overview
Network Coverage and Capacity
The Aprisa SRi has a typical link range of up to 50 km, however, geographic features, such as hills,
mountains, trees and foliage, or other path obstructions, such as buildings, will limit radio coverage.
Additionally, geography may reduce network capacity at the edge of the network where errors may occur
and require retransmission. However, the Aprisa SRi uses 0.4 W (+26 dBm) output power and Forward Error
Correction (FEC) which greatly improves the sensitivity and system gain performance of the radio resulting
in less retries and minimal reduction in capacity.
Ultimately, the overall performance of any specific network will be defined by a range of factors including
the RF output power, the modulation used and its related receiver sensitivity, the geographic location,
the number of remote stations in the base station coverage area and the traffic profile across the
network. Effective network design will distribute the total number of remote stations across the available
base stations to ensure optimal geographic coverage and network capacity.
One base station can register and operate with up to 500 remote stations.
The practical limit of remote stations that can operate with one base station is determined by a range of
factors including the number of services, the packet sizes, the protocols used, the message types and
network timeouts.
Automatic Registration
On start-up, the remote station listens for the base station before attempting registration. It then
transmits a registration message to the base station which responds with a registration response. The base
station records the details of all the remote stations active in the network.
If a remote station cannot register with the base station after multiple attempts within 10 minutes, it will
automatically reboot. If remote is not able to register with base station in 5 attempts, then a ‘Network
Configuration Warning’ alarm event will be raised indicating that a remote is not registered with the base
station.
If a remote station has registered with the base station but then loses communication, it will
automatically reboot within 2 minutes.
Remote Messaging
There are two message types in the Aprisa SRi network, broadcast messages and unicast messages.
Broadcast messages are transmitted by the base station to the remote stations and unicast messages are
transmitted by the remote station to the base station. These messages are commonly referred to as uplink
(unicast remote to base) and downlink (broadcast base to remote).
All remotes within the coverage area will receive broadcast messages and pass them on to either the
Ethernet or serial interface. The RTU determines if the message is intended for it and will accept it or
discard it.

Product Operation
There are three components to the wireless interface: the Physical Layer (PHY), the Data Link Layer (DLL)
and the Network Layer. These three layers are required to transport data across the wireless channel in
the Point-to-Multipoint (PMP) configuration. The Aprisa SRi DLL is largely based on the 802.15.4 Media
Access Control (MAC) layer using a proprietary implementation.
Physical Layer
The Aprisa SRi PHY uses a one frequency half duplex transmission mode which eliminates the need for a
duplexer.
Remote nodes are predominantly in receive mode with only sporadic bursts of transmit data. This reduces
power consumption.
The Aprisa SRi is a packet based radio. Data is sent over the wireless channel in discrete packets / frames,
separated in time. The PHY demodulates data within these packets with coherent detection.
The Aprisa SRi PHY provides carrier, symbol and frame synchronization predominantly through the use of
preambles. This preamble prefixes all packets sent over the wireless channel which enables fast
Synchronization.
Aprisa SRi User Manual 1.0.0
24 | About the Radio
Data Link Layer / MAC layer
The Aprisa SRi PHY enables multiple users to be able to share a single wireless channel; however a DLL is
required to manage data transport. The two key components to the DLL are channel access and hop by
hop transmission.
Channel Access
The Aprisa SRi radio uses a channel access of Access Request. Channel access scheme where the base
stations controls the communication on the channel. Remotes ask for access to the channel, and the base
station grants access if the channel is not occupied.
Access Request
This scheme is particularly suited to digital SCADA systems where all data flows through the base station.
In this case it is important that the base station has contention-free access as it is involved in every
transaction. The channel access scheme assigns the base station as the channel access arbitrator and
therefore inherently it has contention-free access to the channel. This means that there is no possibility
of contention on data originating from the base station. As all data flows to or from the base station, this
significantly improves the robustness of the system.
All data messages are controlled via the AG (access grant) control message and therefore there is no
possibility of contention on the actual end user data. If a remote station accesses the channel, the only
contention risk is on the AR (access request) control message. These control messages are designed to be
as short as possible and therefore the risk of collision of these control messages is significantly reduced.
Should collisions occur these are resolved using a random back off and retry mechanism.
As the base station controls all data transactions multiple applications can be effectively handled,
including a mixture of polling and report by exception.
Aprisa SRi User Manual 1.0.0
About the Radio | 25
Hop by Hop Transmission
Hop by Hop Transmission is realized in the Aprisa SRi by adding a MAC address header to the packet. For
802.15.4, there are 2 addresses, the source and destination addresses.
Adaptive Coding and Modulation
The Aprisa SRi provides Adaptive Coding and Modulation (ACM) which maximizes the use of the RF path to
provide the highest radio capacity available.
ACM automatically adjusts the modulation coding and FEC code rate in the remote to base direction of
transmission over the defined modulation range based on the signal quality for each individual remote
radio.
When the RF path is healthy (no fading), modulation coding is increased and the FEC code rate is
decreased to maximize the data capacity.
If the RF path quality degrades, modulation coding is decreased and the FEC code rate is increased for
maximum robustness to maintain path connectivity.

Network Layer
Packet Routing
Aprisa SRi is a standard static IP router which routes and forwards IP packet based on standard IP address
and routing table decisions.
Aprisa SRi router mode (see figure below), enables the routing of IP packets within the Aprisa SRi wireless
network and in and out to the external router / IP RTUs devices connected to the Aprisa SRi wired
Ethernet ports.
Within the Aprisa SRi Router mode, each incoming Ethernet packet on the Ethernet port is stripped from
its Ethernet header to reveal the IP packet and to route the IP packet based on its routing table. If the
destination IP address is one of the RTUs, the packet is then forwarded to the wireless ports and
broadcasted as a PMP wireless packet to all the remote stations. The appropriate remote then routes the
IP packet and forwards it based on its routing table to the appropriate Ethernet port, encapsulating the
appropriate next hop MAC header and forwarding it to the RTU. The RTU can then interpret and process
the IP data and communication is established between the RTU and the initiating communication device.
Aprisa SRi User Manual 1.0.0
About the Radio | 27
Static IP Router
The Aprisa SRi works in the point-to-multipoint (PMP) network as a standard static IP router with the
Ethernet and wireless / radio as interfaces and serial ports using terminal server as a virtual interface.
The Aprisa SRi static router is semi-automated operation, where the routing table is automatically created
in the base station and populated with routes to all remote stations in the network during the registration
process and vice versa, where the routing table is automatically created in remote stations and populated
with routes to base station during the registration process. Updates occur when remote is disconnected
from network for any reason, with the routing table updated in a controlled fashion.
Also, in decommission operation, the base station routing tables are completely flushed allowing an
automatic rebuild. This avoids the user manually inserting / removing of multiple static routes to build /
change the routes in the network which might be tedious and introduce significant human error. The
Aprisa SRi works as a static IP router without using any routing protocol and therefore does not have the
overhead of a routing protocol for better utilization of the narrow bandwidth network.
In addition to the semi-automated routes, the user can manually add / remove routes in the routing table
for the radio interface, Ethernet Interface and for routers which are connected to the radio network.
The Aprisa SRi base station is used as a gateway to other networks. Thus, a configurable IP address default
gateway can be set using a static route in the routing table with a destination IP address of the
destination network address. It is recommended to use a real network IP address (actual device IP) for the
gateway and not 0.0.0.0.
The Aprisa SRi sub-netting rules distinguish between the wireless interface and the remote Ethernet
interface where RTUs are connected. The entire wireless network is set on a single IP subnet, while each
Aprisa SRi remote’s Ethernet interface is set to a different subnet network. In this way, the user can easily
distinguish between the remotes subnet IP addresses.

The Radio Network as a Gateway Router
The Aprisa SRi point-to-multipoint radio network can be considered as a gateway router where the
‘network Ethernet interface’ on each radio in the network is the ‘router port’.
The routing table for all directly attached devices to the Aprisa SRi network, at the Base or the Remote
stations is automatically built and no static routes are required to be entered for those device routes.
The ‘Radio interface IP address’ is used internally for the radio network and automatic routes. It is not
used when setting static routes or default gateways.
Static route IP addresses or the default gateway should use the ‘network Ethernet interface’ IP address.
External network routers should be set with a high metric for the SRi path, to prevent route updates being
sent over the radio network.
The Radio Network as a Router – Example
The purpose of this example is to determine the static route setting for router R2 in the base station and
remote station in the following network.
Since the Aprisa SRi network should be considered as a router where the network Ethernet interface is the
‘router port’, the network configuration for setting the static routes or the default gateway IP addresses is
described in the follow figure:
Thus, the static route setting for router R2 at the Aprisa SRi base station and remote station will be:
Destination Address
Destination Mask
Gateway Address
Static Route Setting at ?

255.255.255.0
192.168.2.2

Note: The radio network (base station and remote stations) will automatically build routes to the attached
device e.g. SCADA Master station or attached router e.g. router R1 so static routes are not required for
these devices.

About the Radio | 29
Static IP Router – Human Error Free
To ensure correct operation, the Aprisa SR router base station alerts when one (or more) of the devices is
not configured for router mode or a duplicated IP is detected when manually added.
When the user changes the base station IP address / subnet, the base station sends an ARP unsolicited
announcement message and the remote stations auto-update their routing table accordingly. This also
allows the router that is connected to the base station to update its next hop IP address and its routing
table.
When the user changes the remote station IP address / subnet, a re-registration process in the base
station then auto-updates its routing table accordingly.
Terminal Server - Transition to Converged Ethernet / IP Network
Customers that are transitioning their SCADA network to an Ethernet / IP SCADA network, can
simultaneously operate their legacy serial RTUs, not as a separate serial network to the new Ethernet / IP
network, but as part of the Ethernet / IP network, by using the terminal server feature.
The Aprisa SR terminal server is an application running in the radio that encapsulates serial traffic into
Ethernet / IP traffic. For SCADA networks, this enables the use of both serial and Ethernet / IP RTUs
within an Ethernet / IP based SCADA network.

Bridge Mode with VLAN Aware
Ethernet VLAN Bridge / Switch Overview
The Aprisa SRi in Bridge mode of operation is a standard Ethernet Bridge based on IEEE 802.1d or VLAN
Bridge based on IEEE 802.1q/p which forward / switch Ethernet packet based on standard MAC addresses
and VLANs using FDB (forwarding database) table decisions. VLAN is short for Virtual LAN and is a virtual
separate network, within its own broadcast domain, but across the same physical network.
VLANs offer several important benefits such as improved network performance, increased security and
simplified network management.
The Aprisa SRi Bridge mode (see figure below), is the default mode of operation and it enables the
switching / bridging of Ethernet VLAN tagged or untagged packets within the Aprisa SRi wireless network
and in and out to the external Industrial LAN network and RTUs devices connected to the Aprisa SRi wired
Ethernet ports or serial ports through the terminal server function.
Within the Aprisa SRi Bridge mode, each incoming Ethernet packet is inspected for the destination MAC
address (and VLAN) and looks up its FDB table for information on where to send the specific Ethernet
frame. If the FDB table doesn’t contain the specific MAC address, it will flood the Ethernet frame out to
all ports in the broadcast domain and when using VLAN, the broadcast domain is narrowed to the specific
VLAN used in the packet (i.e. broadcast will be done only to the ports which configured with that specific
VLAN).
The FDB table is used to store the MAC addresses that have been learnt and the ports associated with that
MAC address. If the destination MAC address is one of the RTUs, the packet is then forwarded to the
wireless ports and broadcast as a PMP wireless packet to all the remote stations. The appropriate remote
then switches the Ethernet packet and forwards it based on its FDB table (based on the MAC or VLAN &
MAC) to the appropriate Ethernet port to the RTU. The RTU can then interpret and process the Ethernet /
IP data and communication is established between the RTU and the initiating communication device.

VLAN Bridge Mode Description
General – Aprisa SRi VLAN Bridge
The Aprisa SRi works in a point-to-multipoint (PMP) network as a standard VLAN bridge with the Ethernet
and wireless / radio as interfaces and serial ports using terminal server as a virtual interface.
The Aprisa SRi is a standard IEEE 802.1q VLAN bridge, where the FDB table is created by the bridge
learning / aging process. New MACs are learnt and the FDB table updated. Unused MACs are aged out and
flushed automatically after aging period.
VLANs are statically configured by the user on the ports where a Virtual LAN is required across the radio
network. An example of VLAN isolation of traffic type is shown in the figure below, where RTUs #1, 4 and
6 together with SCADA meter master form a Virtual LAN which is isolated from the other devices, even
though they are on the same physical network. VLAN management can be used to manage with external
NMS all the Aprisa SRi devices on the radio network and is automatically created with a VLAN ID = 1
default value. The VLAN ID can be changed by the user later on.
Each device in the Aprisa SRi bridge is identified by its own IP address, as shown in the figure.
Aprisa SRi User Manual 1.0.0
32 | About the Radio
VLANs – Single, Double and Trunk VLAN ports
The Aprisa SRi supports single VLAN (CVLAN), double VLAN (SVLAN) and trunk VLAN.
A single VLAN can be used to segregate traffic type.
A double VLAN can be used to distinguish between Aprisa SRi sub-networks (remotes), where the outer
SVLAN is used to identify the sub-network and the CVLAN is used to identify the traffic type. In this case,
a double tagged VLAN will be forwarded across the Industrial LAN network and switched based on the
SVLAN to the appropriate Aprisa SRi sub-network. When packet enters the Aprisa SRi network, the SVLAN
will be stripped off (removed) and the forwarding will be done based on the CVLAN, so only a single VLAN
will pass through over the radio network and double VLAN will be valid on the borders of the radio
network.
Trunk VLAN is also supported by the Aprisa SRi where the user can configure multiple VLANs on a specific
Ethernet port, creating a trunk VLAN port. For example, in the above figure, a single trunk VLAN port is
created between the switch and the Aprisa SRi base station, carrying VLAN ID #1, 20, 30 and 40.
VLAN Manipulation – Add / Remove VLAN Tags
In order to support double VLAN and different device types connected to the Aprisa SRi e.g. switches,
RTUs, etc, which can be VLAN tagged or untagged / plain Ethernet devices, add / remove VLAN
manipulation is required.
In an Aprisa SRi VLAN tagged network, a remote Aprisa SRi connected to a plain RTU without VLAN
support, will remove (strip-off) the VLAN tag from the packet before sending it to the RTU. On the other
direction, when the RTU is sending an untagged packet, the Aprisa SRi will add (append) an appropriate
user pre-configure VLAN tag before sending it over the air to the base station. This is shown in the above
figure on untagged RTU #5 and 7.
QoS using VLAN
VLANs carry 3 priority bits (PCP field) in the VLAN tag allowing prioritization of VLAN tagged traffic types
with 8 levels of priority (where 7 is the highest priority and 0 is the lowest priority). The Aprisa SRi
supports QoS (Quality of Service) where the priority bits in the VLAN tagged frame are evaluated and
mapped to four priority levels and four queues supported by the Aprisa SRi radio. Packets in the queues
are then scheduled out in a strict priority fashion for transmission over-the-air as per the priority level
from high to low.

About the Radio | 33
Avoiding Narrow Band Radio Traffic Overloading
The Aprisa SRi supports mechanisms to prevent narrowband radio network overload:
1.
L3/L4 Filtering
The L3 filtering can be used to block undesired traffic from being transferred on the narrow band channel,
occupying the channel and risking the SCADA critical traffic. L3/4 filtering has the ability to block a known
IP address and applications using TCP/IP or UDP/IP protocols with multiple filtering rules. The L3 (/L4)
filter can block/forward (discard/process) a specific IP address and a range of IP addresses. Each IP
addressing filtering rule set can also be set to filter a L4 TCP or UDP port/s which in most cases relates to
specific applications as per IANA official and unofficial well-known ports. For example, filter and block Email SMTP or TFTP protocol as undesired traffic over the SCADA network. The user can block a specific or
range of IP port addresses, examples SMTP (Simple Mail Transfer Protocol) TCP port 25 or TFTP (Simple
Trivial File Transfer Protocol) UDP port 69.
2.
L2 Address Filtering
L2 Filtering (Bridge Mode) provides the ability to filter radio link traffic based on specified Layer 2 MAC
addresses. Destination MAC (DA) addresses and a Source MAC (SA) addresses and protocol type (ARP, VLAN,
IPv4, IPv6 or Any type) that meet the filtering criteria will be transmitted over the radio link. Traffic that
does not meet the filtering criteria will not be transmitted over the radio link.
3.
L2 Port VLANs Ingress Filtering and QoS
Double VLAN (Bridge Mode)
Double VLAN is used to distinguish/segregate between different radio sub-networks (remotes). Traffic
with double VLANs which are not destined to a specific sub-network will be discarded on the ingress of the
radio sub-network, avoiding the overload of the radio sub-network.
Single VLAN (Bridge Mode)
Single VLAN is used to distinguish/segregate between different traffic types assigned by the user in its
industrial corporate LAN. In order to avoid the overload of the radio network, traffic with single VLANs
which are not destined to a specific radio network will be discarded on the Ethernet ingress port of the
radio network. All single VLANs which set and are eligible will be transmitted over the radio link.
QoS using 802.1p priority bits (Bridge Mode)
The priority bits can be used in the VLAN tagged frames to prioritized critical mission SCADA traffic and
ensure SCADA traffic transmission relative to any other unimportant traffic. In this case, traffic based on
VLAN priority (priority 0 to 7) enters one of the four priority queues of the Aprisa SRi (Very High, High,
Medium and Low). Traffic leaves the queues (to the radio network) from highest priority to lowest in a
strict priority fashion.
4.
Ethernet port QoS
The Aprisa SRi supports ‘Ethernet Per Port Prioritization’. Each Ethernet port can be assigned a priority
and traffic shall be prioritized accordingly. This is quite useful in networks where customers do not use
VLANs or cannot use 802.1p prioritization.
Aprisa SRi User Manual 1.0.0
34 | About the Radio
5.
Ethernet Data and Management Priority and Background Bulk Data Transfer Rate
Alternatively to VLAN priority, users can control the Ethernet traffic priority (vs serial), management
priority and rate in order to control the traffic load of the radio network, where important and high
priority data (SCADA) will pass-through first assuring SCADA network operation. The user can set the use of
the Ethernet Data Priority, which controls the priority of the Ethernet customer traffic relative to the
serial customer traffic and can be set to one of the four queues. The Ethernet Management Priority
controls the priority of the Ethernet management traffic relative to Ethernet customer traffic and can be
set to one of the four queues. The Background Bulk Data Transfer Rate sets the data transfer rate (high,
medium, low) for large amounts of management data.
6.
Ethernet Packet Time to Live
Another aspect of avoiding overload radio network is the Ethernet packet TTL, which is used to prevent
old, redundant packets being transmitted through the radio network. This sets the time an Ethernet
packet is allowed to live in the system before being dropped if it cannot be transmitted over the air.
7.
Payload Compression
Aprisa SRi supports payload compression. A Lempel–Ziv (LZ) algorithm is used to efficiently compress up to
50% traffic with high percentage of repetitive strings. Both serial and Ethernet / IP payload traffic are
compressed.

Hardware Alarm Inputs / Outputs
The Aprisa SRi provides two hardware alarm inputs to generate alarm events in the network and two
hardware alarm outputs to receive alarm events from the network.
The hardware alarm inputs and outputs are part of the event system. All alarm events can be viewed in
SuperVisor event history log (see ‘Events > Event History’ on page 198). These include the alarm events
generated by the hardware alarm inputs.
Alarm Input to SNMP Trap
An alarm event from an Aprisa SRi hardware alarm input can be sent over the air to any SNMP Manager
using SNMP traps.
Alarm Input to Alarm Output
An alarm event from an Aprisa SRi hardware alarm input can be mapped to an hardware alarm output of
another SRi using an event action setup (see ‘Events > Event Action Setup’ on page 205).
Aprisa SR Alarm Input to Aprisa SRi Alarm Output
The Aprisa SRi event action setup feature is compatible with the Aprisa SR.
Since, the Aprisa SR only supports hardware alarm inputs, the Aprisa SRi can be used as an option to

Bench Setup
Before installing the links in the field, it is recommended that you bench-test the links. A suggested setup
for basic bench testing is shown below:
When setting up the equipment for bench testing, note the following:
Earthing
Each radio should be earthed at all times. The radio earth point should be connected to a protection
earth.
Attenuators
In a bench setup, there should be 60 - 80 dB at up to 1 GHz of 50 ohm coaxial attenuation, capable of
handling the transmit power of +26 dBm (0.4 W) between the radios’ antenna connectors.
Splitter
If more than two radios are required in your bench setup, a multi-way splitter is required. The diagram
shows a two way splitter. This splitter should be 50 ohm coaxial up to 1 GHz and capable of handling the
transmit power of +26 dBm (0.4 W).
Cables
Use double-screened coaxial cable that is suitable for use up to 1 GHz at ≈ 1 metre.
CAUTION: Do not apply signals greater than +10 dBm to the antenna connection as they can damage the
receiver.

Compliance Considerations
The Aprisa SRi is a professional radio product and as such must be installed by a suitably trained and
qualified installer who is aware of the local regulatory requirements existing at the time of installation
and is capable of ensuring that the regulations are adhered to.
The maximum Equivalent Isotropic Radiated Power (EIRP) permitted from the Aprisa SRi is regulated and
must not exceed the limits provided in the following table. To meet this regulatory requirement;
knowledge of the antenna gain and feeder cable loss must be known before setting the transmitter output
power.

The Aprisa SRi has a maximum mean output power of +26 dBm into a 50 ohm antenna which equates to a
maximum peak power of +30 dBm PEP. To determine the maximum power to be set on the Aprisa SRi, the
following installation parameters must be known:
1.
Aprisa SRi equivalent average power for maximum permitted EIRP (specified in dBm)
RdBm
2.
Antenna isotropic gain (specified in dBi)
GdBi
3.
Feeder coax loss between Aprisa SRi and antenna (specified in dB/m)
LdB/m
4.
Length of feeder coax between Aprisa SRi and antenna (specified in metres)
dm
From these the above information, the power setting of the Aprisa SRi (PdBm) can be calculated to ensure
operation within the regulatory requirements using the formula:
𝑃𝑑𝐵𝑚 = 𝑅𝑑𝐵𝑚 + (𝑑𝑚 × 𝐿𝑑𝐵/𝑚 ) − 𝐺𝑑𝐵𝑖
Antenna gain information can be obtained from the Antenna manufacturer and is either expressed in
terms of dBi, referenced to an isotropic radiator, or dBd, referenced to a dipole.
If the gain is expressed in dBd, it can be converted to dBi by adding 2.15 dB to the gain value.
These are correct at the time of printing. The installer must ensure that the installation complies with the
regulatory requirements at the time of installation.

Antenna Siting
When siting antennas, consider the following points:
A site with a clear line of sight to the remote radio is recommended. Pay particular attention to trees,
buildings, and other obstructions close to the antenna site.
Example of a clear line-of-sight path
Any large flat areas that reflect RF energy along the link path, for instance, water, could cause multipath
fading. If the link path crosses a feature that is likely to cause RF reflections, shield the antenna from the
reflected signals by positioning it on the far side of the roof of the equipment shelter or other structure.
Example of a mid-path reflection path
The antenna site should be as far as possible from other potential sources of RF interference such as
electrical equipment, power lines and roads. The antenna site should be as close as possible to the
equipment shelter.
Wide angle and zoom photographs taken at the proposed antenna location (looking down the proposed
path), can be useful when considering the best mounting positions.

1. Open your web browser and enter the IP address of the radio.
If you haven’t assigned an IP address to the radio, use the factory default IP address of 169.254.50.10 with
a subnet mask of 255.255.0.0.
If you don’t know the IP address of the radio, you can determine it using the Command Line Interface (see
‘Command Line Interface’ on page 253).
Note: The Aprisa SRi has a randomly generated unique self-signed ECC256 security certificate which may
cause the browser to prompt a certificate warning. It is safe to ignore the warning and continue. The valid
certificate is ‘Issued By: 4RF-APRISA’ which can be viewed in the browser.
2. Login with the Username and Password assigned to you.
If unique usernames and passwords have not yet been configured, use the default username ‘admin’ and
password ‘admin’.
Important: After you login for the very first time, it is recommended that you change the default admin
password for security reasons (see ‘Changing Passwords’ on page 171).

CHANNEL SETTINGS
Maximum Packet Size (Bytes)
This parameter sets the maximum over-the-air packet size in bytes. A smaller maximum Packet Size is
beneficial when many remote stations are trying to access the channel. The default setting is 1550 bytes.
As radios dispatched from the factory have a Packet Size set to the maximum value of 1550 bytes, if a new
radio is installed in an existing network, the Packet Size must be changed to ensure it is the same value
for all radios in the network. The new radio will not register an existing network if the Packet Size is not
the same as the other radios in the network.
This packet size includes the wireless protocol header and security payload (0 to 16 bytes). The length of
the security header depends on the level of security selected.
When the security setting is 0, the maximum user data transfer over-the-air is 1516 bytes.
When encryption is enabled, the entire packet of user data (payload) is encrypted. If authentication is
being used, the security frame will be added (up to 16 bytes). The wireless protocol header is then added
which is proprietary to the Aprisa SRi. This is not encrypted.

Option
Function
Disabled
Every packet received by the radio will be forwarded to the
relevant interface.
Automatic
The radio will filter (discard) packets not destined for itself
according to the Aprisa SRi traffic protocols
The default setting is Automatic.
Note: The Aprisa SRi network is transparent to the protocol being transmitted; therefore the Packet
Filtering parameter is based on the Aprisa SRi addressing and network protocols, not the user (SCADA,
etc.) traffic protocols.
Serial Data Stream Mode
This parameter controls the traffic flow in the radio serial ports.
Option
Function
Broadcast
Serial port traffic from the network is broadcast on all serial ports
on this radio. This will include the RS-232 port derived from the

Default Packet Time to Live (ms)
This parameter sets the default time a packet is allowed to live in the system before being dropped if it
cannot be transmitted over the air. It is used to prevent old, redundant packets being transmitted through
the Aprisa SRi network. The default setting is 1500 ms.
In the case of serial poll SCADA networks such as MODBUS and IEC 60870.50.101, it is important to ensure
the replies from the RTU are in the correct sequence and are not timed out replies from Master requests.
If the TTL value is too long, the SCADA master will detect sequence errors.
It is recommended to use a TTL which is half the serial SCADA timeout. This is commonly called the ‘scan
timeout’ or ‘link layer time out’ or ‘retry timeout’.
When using TCP protocols, a TTL of 1500 ms is recommended because a TCP re-transmission usually occurs
after approximately 3 seconds.
In SCADA networks which use both serial and Ethernet, it is recommended that the TTL is set to half the
serial SCADA timeout for serial remotes, and 1500 ms for Ethernet (TCP) remotes. For example, if the
serial SCADA timeout is 1000 ms, a remote radio which is connected to the serial RTU should be set to
500 ms, a remote radio which is connected to an Ethernet (TCP) RTU should have a 1500 ms timeout.
In this case, the base station TTL should be set to 1500 ms as well; or whichever is the longer TTL of serial
or Ethernet.

Serial Line Interface Protocol (SLIP)
This menu item is only applicable if the serial port has an operating mode of SLIP.
The SLIP operating mode provides IP packet encapsulation over RS-232 serial interface as per the SLIP
protocol RFC 1055.
A SLIP serial interface contains the IP address of the serially connected RTU as per the RTU/PLC SLIP
protocol. The SLIP interfaces on the remote radios can be part of the bridge network and can coexist and
operate with a mix of Ethernet interfaces, serial SLIP and terminal server interfaces.
As the RTU/PLC serial SLIP interface doesn't support MAC addresses, a remote radio SLIP interface uses a
proxy ARP function that returns its own MAC address for ARP requests based on the IP address of the
RTU/PLC SLIP interface.
Serial Device IP Address
This parameter sets the IP address of the RTU connected on the configured serial port.

PORT PARAMETERS
Ingress Filtering Enabled
This parameter enables ingress filtering. When enabled, if ingress VLAN ID is not included in its member
set (inner tagged), the frame will be discarded.
If the Ingress Filtering is disabled, the Aprisa SRi supports ‘Admit All Frames’ so that all frames tagged,
untagged and priority-tagged-frames are allowed to pass through the Ethernet ports. The default is
disabled.
Double Tagging Enabled
This parameter enables double tagging on this specific port. When enabled, if the ingress traffic is double
tagged, the Aprisa SRi will check and validate that the S-VLAN ID matches the S-VLAN defined in 'Double
Tag Egress S-VLAN ID' in the 'all ports' tab. If there is a match, the packet will be forwarded into the
Bridge and the S-VLAN outer tag will be removed, thus the radio network will only forward a single VLAN.
If there isn’t a matching S-VLAN, the packet will be discarded. On egress, the outer tag (S-VLAN) is
appended with the 'Double Tag Egress S-VLAN ID' defined in the 'all ports' tab (see page 121). The default
is disabled.
Aprisa SRi User Manual 1.0.0
124 | Managing the Radio
If double tagging is enabled on the port, incoming frames should always be double tagged.

If the incoming frame is untagged, then the PVID (port VLAN ID) is used and forwarded with the Port
Ingress priority provided the PVID is configured in the Port VLAN Membership of any of the Ethernet
ports. If not, the frames are dropped.

If the incoming frame is single tagged, then PVID is used and forwarded with the Port Ingress priority
provided the PVID is configured in the Port VLAN Membership of any of the Ethernet ports. If not the
frames are dropped.
If double tagging is disabled on the port, incoming frames should always be single tagged, untagged or
priority–tagged frames.
Double tagged frames are simply forwarded treating them as if they were single tagged frames. At the
egress of the Ethernet port, such frames are forwarded only if the S-VLAN ID of that frame is a member of
the Port VLAN Membership.
PVID (Port VLAN ID)
This parameter sets the frame VLAN ID when the ingress frame is untagged (e.g. when in 'port VLAN
membership' the 'egress action' is set to 'untagged and forward') or priority-tagged (VLAN=0). The value
can be between 1 and 4094. The default is 1.
Note: The Port VLAN Membership must contain the PVID. If the Port VLAN Membership does not contain
the PVID, untagged or priority-tagged frames will be discarded.
COPY VLAN MEMBERSHIP

This specifies the duration (in seconds) to automatically terminate the connection with the remote TCP
server if no data has been received from either the remote TCP server or its associated serial port for the
duration of the configured inactivity time.
TCP Keep Alive
A TCP keep alive is a message sent by one device to another to check that the link between the two is
operating, or to prevent the link from being broken.
If the TCP keep alive is enabled, the radio will be notified if the TCP connection fails.
If the TCP keep alive is disabled, the radio relies on the Inactivity Timeout to detect a TCP connection
failure. The default setting is disabled.
Note: An active TCP keep alive will generate a small amount of extra network traffic.

TRAFFIC PRIORITY
Default Management Data Priority
The Default Management Data Priority controls the priority of the Ethernet management traffic relative to
Ethernet customer traffic. It can be set to Very High, High, Medium and Low. The default setting is
Medium.
This priority is also used for traffic if the remote serial port is not available for the radio hardware data
port option e.g. if the base station is 2E2S and a remote radio is 4E0S.
SERIAL PRIORITY
This parameter controls the per port priority of the serial customer traffic relative to the Ethernet
customer traffic. If equal priority is required to Ethernet traffic, this setting must be the same as the
Ethernet Data Priority setting.
The serial data priority can be set to Very High, High, Medium and Low. The default setting is Low.
A queuing system is used to prioritize traffic from the serial and Ethernet interfaces for over the air
transmission. A weighting may be given to each data type and this is used to schedule the next
transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a
higher weighting it will be transmitted first. The serial buffer is 20 serial packets (1 packet can be up to
512 bytes).
There are four priority queues in the Aprisa SR: Very High, High, Medium and Low. Data is added to one of
these queues depending on the priority setting. Data leaves the queues from highest priority to lowest:
the Very High queue is emptied first, followed by High then Medium and finally Low.

PRIORITY DEFINITIONS
PCP (Priority Code Point)
These settings provide priority translation / mapping between the external radio LAN VLAN priority
network and the radio internal VLAN priority network, using the VLAN tagged PCP (Priority Code Point)
priority field in the Ethernet/VLAN frame.
The IEEE 802.1Q specification defines a standards-based mechanism for providing VLAN tagging and class
of service (CoS) across Ethernet networks. This is accomplished through an additional VLAN tag, which
carries VLAN tag ID and frame prioritization information (PCP field), inserted within the header of a Layer
2 Ethernet frame.
Priority Code Point (PCP) is a 3-bit field that indicates the frame priority level (or CoS). The operation of
the PCP field is defined within the IEEE 802.1p standard, which is an extension of 802.1Q. The standard
establishes eight levels of priority, referred to as CoS values, where CoS 7 (‘111’ in PCP filed) is the
highest priority and CoS 0 (‘000’) is the lowest priority.
The radio in bridge mode used the PCP value in the VLAN tag to prioritize packets and provide the
appropriate QoS treatment per traffic type. The radio implements 4 priority queuing techniques that base
its QoS on the VLAN priority (PCP). Based on VLAN priority bits, traffic can be put into a particular Class of
Service (CoS) queue. Packets with higher CoS will always serve first for OTA transfer and on ingress/egress
Ethernet ports.
The ‘PCP priority definition’ tab is used to map ingress VLAN packet with PCP priority to the radio internal
CoS (priority). Since, in most of the cases the radio VLAN network is connected to the corporate VLAN
networks, the network administrator might like to have a different VLAN priority scheme of the radio
network CoS. For example, management traffic in the multi-gigabit corporate VLAN network might be
prioritize with priority 7 (highest priority) and SCADA traffic with priority 5, but in the narrow bandwidth
radio network, SCADA traffic will be map to radio very high CoS / priority (i.e. set PCP 5 = Very high) and
management traffic might will be map to radio medium CoS / priority (i.e. set PCP 7 = medium) in order
to serve first the mission-critical SCADA traffic over the radio network.

This is done by mapping the external radio network VLAN priority to the internal radio CoS / priority using
the ‘PCP priority definition’ tab. The radio support 4 queues, thus at maximum an 8 -> 4 VLAN priority /
CoS mapping is done.

144 | Managing the Radio
DSCP (Differentiated Services Code Point)
These settings provide translation / mapping between the external radio IP priority network and the radio
internal IP priority network, using the DSCP (DiffServ Code Point) priority field in the IP packet header.
Differentiated Services (DiffServ) is a new model in which traffic is treated by routers with relative
priorities based on the IPv4 type of services (ToS) field. DSCP (DiffServ Code Point) standard defined in
RFC 2474 and RFC 2475. DiffServ increases the number of definable priority levels by reallocating bits of
an IP packet for priority marking.
The DiffServ architecture defines the DiffServ (DS) field, which supersedes the ToS field in IPv4 to make
per-hop behaviour (PHB) decisions about packet classification and traffic scheduling functions. The six
most significant bits of the DiffServ field (in the IPv4 TOS field) is called as the DSCP. The standardized
DiffServ field of the packet is marked with a value so that the packet receives a particular
routing/forwarding treatment or PHB, at each router node. Using DSCP packet classification, traffic can be
partition into multiple priority levels.
The radio in router mode uses the DSCP value in the IP header to select a PHB behaviour for the packet
and provide the appropriate QoS treatment. The radio implements 4 priority queuing techniques that base
its PHB on the DSCP in the IP header of a packet. Based on DSCP, traffic can be put into a particular
priority / CoS (Class of Service) queue. Packets with higher CoS will always serve first for OTA transfer and
on ingress / egress Ethernet ports.
The ‘DSCP priority definition’ tab is used to map ingress IP packet with DSCP priority to the radio internal
priority / CoS. Since, in most of the cases the radio routed network is connected to the corporate routed
networks, the network administrator might like to have a different routed network priority scheme of the
radio network, for example management traffic in the multi-gigabit corporate routed network might be
prioritize with DSCP EF (expedite forwarding) code (DSCP highest priority), and SCADA traffic with DSCP
AF11 (assured forwarding) code (high priority), but in the narrow bandwidth radio network, SCADA traffic
will be map to radio very high CoS / priority (i.e. set AF11 = Very high) and management traffic might map
to radio low CoS / priority (i.e. set EF = Low) in order to serve first the mission-critical SCADA traffic over
the radio network.

This is done by mapping the external radio network DSCP priority to the internal radio CoS / priority levels

QoS > Traffic Classification
These settings provide multiple traffic classification profiles based on classification rules. Profiles for a
specific traffic type, protocol or application can be assigned to a particular VLAN and CoS / priority in
bridge mode or to CoS / priority in router mode to provide the appropriate QoS treatment.
For example SCADA traffic, management traffic, FTP traffic, can each have its own profile build with a set
of classification rules. A profile can be build using multiple classification rules based on ports, Ethernet,
IP, TCP / UDP headers fields (i.e. L1/2/3/4 header fields) such as: Ethernet port #1, VLAN ID, VLAN
priority, IP DSCP Priority, MAC/IP address, TCP / UDP port fields to identify and classify the specific traffic
type. When an ingress packet matches the profile L2/3/4 header fields settings, the packet is assigned to
a particular VLAN and CoS / priority in bridge mode or to CoS / priority in router mode to provide the
appropriate QoS treatment.
The radio supports four CoS / priority queues: very high, high, medium and low. These queues are
connected to a strict priority scheduler which dispatches packets from the queues out to the egress port
by always serving first the ‘very high’ priority queue, whenever there is a packet in this queue. When the
highest priority queue empties, the scheduler will serve the next high priority queues and so on. So when
SCADA traffic is assigned to a ‘Very high’ priority, it will always served first and send over-the-air (OTA)
whenever SCADA traffic enters to the radio, giving it the highest priority over other traffic type.
These settings are different for Bridge Mode and Router Mode.

Bridge Mode Traffic Classification Settings
TRAFFIC CLASSIFICATION
VLAN bridge mode traffic classification settings provide mapping / assigning of profiles (set by rules to
match a specific traffic type) to a VLAN ID and VLAN CoS / priority. The profile which is used to match to
a specific traffic type will be identified in the radio network by its associated VLAN ID and VLAN CoS /
priority to provide the appropriate QoS treatment. CoS / Priority can be set to very high, high, medium,
low priority.
Profile name
A free form field to enter the profile name with a maximum of 32 chars.
Assigned Priority
Traffic packets that match the applied profile rules will be assigned to the selected ‘assigned priority’
setting of Very High, High, Medium and Low. This field cannot be set to Don’t Care.
This applies profile rule mapping to the VLAN CoS / Priority with the appropriate internal radio assigned
priority setting of Very High, High, Medium and Low.
Aprisa SRi User Manual 1.0.0
148 | Managing the Radio
Assigned VLAN ID
Traffic packets that match the applied profile rules will be assigned to the selected ‘assigned VLAN ID’
setting of VLAN ID in the range of 0 to 4095.
A VLAN ID of an ingress packet matching the classification rule (see ‘VLAN ID’ rule in next page) shall be
changed to the ‘assigned VLAN ID’ setting, if below conditions are met:
1. The VLAN ID of Ingress packet is same as PVID of the ingress port.
2. Packet is received untagged at the port
If the VLAN ID of the tagged ingress packet is not the same as the PVID of the ingress port, then it shall
not be changed and the ‘assigned VLAN ID’ setting is ignored i.e. ingress VLANs will pass-through
unchanged.
If ‘assigned VLAN ID’ value is set in the ‘port VLAN membership’ under Ethernet > VLAN (port x tab), then
this VLAN will be available for ingress and egress on the Ethernet and RF ports, otherwise this VLAN will
only be available in one direction on the egress RF port.
For example, if the base station Ethernet port 1 ‘assigned VLAN ID’ = 100 (VLAN-100) and it is also defined
in the ‘port VLAN membership’ under Ethernet > VLAN (port 1 tab) and the remote sends a packet to the
base with a VLAN of 100, this packet will be egress out to Ethernet port 1 (tagged or untagged based on
the ‘egress action’ definition). If the VLAN-100 wasn’t set in the ‘port VLAN membership’, then the base
station will drop a packet from the remote.
This setting parameter can be ‘Don’t Care’ (Assigned VLAN ID = 0) which means that the VLAN ID of ingress
frame will never be modified.

Key Encryption Key Summary
The security of over-the-air-rekeying depends on a truly random Key Encryption Key. This is why the use
of a Raw Hexadecimal key is recommended as a plain text phrase based on known spelling and grammar
constructs is not very random. The default Key Encryption Key is provided only to allow testing of the
security mechanism and is not intended for operational use. Using the default Key Encryption Key
undermines the security of the AES payload encryption because an attacker using the default Key
Encryption Key would immediately recover the AES payload key after the first over-the-air-rekeying event.
When the Security Level is set to Strong, various protections are applied to the Key Encryption Key setting
to prevent tampering. In addition, the Key Encryption Key Type, Key Encryption Key Size, and the Key
Encryption Key itself are all loaded from a customer prepared USB key. This is a one way operation to
prevent key recovery from radios. While the ability to save a Key Encryption Key to USB exists in Standard
Security Level, the Strong Security Level Key Encryption Key is not compromised because the Strong Key
Encryption Key is not the same as the Standard Security Level Key Encryption Key.

SNMPv3 Authentication Passphrase
The SNMPv3 Authentication Passphrase can be changed via the SNMPv3 secure management protocol
interface (not via SuperVisor).
When viewing / managing the details of the users via SNMPv3, the standard SNMP-USER-BASED-SM-MIB
interface is used. This interface can be used to change the SNMPv3 Authentication Passphrase of the users.
The SNMPv3 Authentication Passphrase of a user required to be changed cannot be changed by the same
user i.e. a different user must be used for the transactions.
Generate New Keys from SNMPv3 USM User Passphrases
Net-SNMP is a suite of open source software for using and deploying the SNMP protocol.
functionality is built into many commercial SNMP managers.
Similar
This next step of loading the Aprisa SRi radios with keys generated from USM user passphrases requires the
SNMPv3 USM Management utility provided as part of NET-SNMP.
The utility is called ‘snmpusm’. It provides a range of commands including the management of changing
passwords for SNMPv3 users. In order to use this utility, the user will need to install NET-SNMP on a Linux
(or WindowsÂŽ) or machine. The examples below are from the Linux environment. This tool automatically
obtains the engine ID from the target radio before generating the keys and loading them into the target.

Summary
It is necessary to record the new passphrases loaded into the Aprisa SRi radios and then load the
passphrases into the SNMP manager. There is a separate passphrase for the two supported forms of
authentication (MD5 and SHA1) only as well as the two forms of authentication used in combination the
two forms of encryption (DES and AES). It is vital to change all passphrases even if the depreciated
mechanism are not used (MD5 and DES) otherwise an attacker could still use the default passphrases.

Reset Unknown Passphrases with the Command Line Interface
As it is not possible for users to read previously set passphrases, a CLI command is available from Aprisa
SRi software release 1.4.0 to ‘reset’ the SNMPv3 USM users back to defaults.
Note: USM users are not related to CLI and SuperVisor users. This command will only be accessible to the
CLI ‘admin’ user logins.
To reset unknown passphrases:
1. Telnet into each radio in the network and via the CLI reset the passphrases
2. Login to the radio with:
Login: admin
Password: *********
3. Set all SNMP3 users to default values with the ‘snmpusm reset’ command (see ‘SNMP3 users to default

SNMPv3 Context Addressing
SNMPv3 is not user configurable and user can use this option with any NMS. The radio SNMP management
interface supports SNMPv3/2 context addressing. The SNMv3 context addressing allows the user to use
secure SNMPv3 management while improving NMS performance.
A NMS (Network Management System) can access any remote radio directly by using its IP address or via
the base / master station SNMPv3 context addressing. The SNMPv3 context addressing can compress the
SNMPv3 management traffic OTA (Over The Air) to the remote station by up to 90% relative to direct OTA
SNMPv3 access to remote station, avoiding the radio narrow bandwidth traffic loading.

Security > SNMP
In addition to web-based management (SuperVisor), the network can also be managed using the Simple
Network Management Protocol (SNMP) using any version of SNMP v1/2/3. MIB files are supplied, and these
can be used by a dedicated SNMP Manager, such as Castle Rock’s SNMPc, to access most of the radio’s
configurable parameters.
For communication between the SNMP manager and the radio, Access Controls and Community strings
must be set up as described in the following sections.
A SNMP Community String is used to protect against unauthorized access (similar to a password). The
SNMP agent (radio or SNMP manager) will check the community string before performing the task
requested in the SNMP message.
ACCESS CONTROL SETUP
A SNMP Access Control is the IP address of the radio used by an SNMP manager or any other SNMP device
to access the radio. The Aprisa SRi allows access to the radio from any IP address.

The default Read Only community string is public.
Read Write
The default ReadWrite community string is private.

SNMP Manager Setup
The SNMP manager community strings must be setup to access the base station and remote stations.
To access the base station, a community string must be setup on the SNMP manager the same as the
community string setup on the radio (see ‘Security > SNMP’ on page 173).
SNMP access to remote stations can be achieved by using the radio’s IP address and the normal community
string or by proxy in the base station.
SNMP Access via Base Station Proxy
To access the remote stations via the base station proxy, the community strings must be setup on the
SNMP manager in the format:
ccccccccc:bbbbbb
Where:
ccccccccc is the community string of the base station
and
bbbbbb is the last 3 bytes of the remote station MAC address (see ‘Network Status > Network Table’
on page 246).
The SNMP Proxy Support must be enabled for this method of SNMP access to operate (see ‘SNMP Proxy
Support’ on page 166).

This page displays the current settings for the Security RADIUS.
RADIUS - Remote Authentication Dial In User Service
RADIUS is a client / server system that secures the radio link against unauthorized access. It is based on
open standard RFCs: RFC 2865/6, 5607, 5080 and 2869. It is used for remote user Authorization,
Authentication and Accounting.
When a user logs into a radio with RADIUS enabled, the user’s credentials are sent to the RADIUS server
for authentication of the user.
Transactions between the RADIUS client and RADIUS server are authenticated through the use of a shared
secret, which is never sent over the network.
For a RADIUS server to respond to the radio, it must configured with and respond to the following
Management-Privilege-level attributes:
Admin Level = 4
Technician Level = 2
Viewer Level = 1
A RADIUS server can act as a proxy client to other RADIUS servers or other kinds of authentication servers.

REMOTE PAYLOAD SECURITY PROFILE ACTIVATION
When the security profile has been distributed to all the remote stations, the security profile is then
activated in all the remote stations with this command.
The base station will always attempt to distribute the profile successfully. This broadcast distribution has
its own retry mechanism. The user can find out if all the remote radios have the latest profile when the
managed activation process is attempted. A pop up confirmation will be shown by SuperVisor with
relevant information and the user can decide to proceed or not. The user can attempt to redistribute
again if needed. If the decision is made to continue, on completion of the activation process,
communication with the remote radios that did not have the new security profile will be lost.
Predefined Profile Name
This parameter displays the predefined security profile available for activation on all remote stations.
To activate the security profile in remote stations:
This process assumes that a security profile has been setup into the base station (see ‘Security > Setup’ on
page 162) and distributed to all remote radios in the network.
Note: Do not navigate SuperVisor away from this page during the activation process (SuperVisor can lose
PC focus).
1. Click Start Activation
The remote stations will be polled to determine which radios require activation:

Node Registration Retry (sec)
This parameter sets the base station poll time at startup or the remote station time between retries until
registered. The default setting is 10 seconds.
Base Station Announcement Period (min)
This parameter sets the period between base station polls post startup. The default setting is 1440
minutes (24 hours).
When a new base station powers on, it announces its presence and each remote that receives the
announcement message will be advised that a new base station is present and that they should re-register.
This allows the new base station to populate its Network Table, with knowledge of the nodes in the
network.
If, during this initial period, there is some temporary path disturbance to one or more remotes, they may
miss the initial announcement messages and be left unaware of the base station change. For this reason,
the base station must periodically send out announcement messages to pick up any stray nodes and the
period of these messages is the base station Announcement Period.
Setting this parameter to 0 will stop periodic announcement messages being transmitted.
If a critical parameter is changed in the base station, such as IP address, then the change is distributed to
the network using base station announcement message. Note that in this case, an announcement is sent
immediately independent of the Announcement Period setting.

Discover Nodes
This parameter when activated triggers the base station to poll the network with Node Missed Poll Count
and Node Registration Retry values.
Decommission Node(s)
This parameter when activated resets the network registrations to remove the entire network from
service.
Note: Take care using this option.
Broadcast Time
This parameter when activated sends the base station Date / Time setting to all the remote stations in the
network and sets their Date / Time. This option applies to the base station only.
Automatic Route Rediscovery
This parameter enables the radio to transmit route discovery messages when packets are unacknowledged.
When enabled, unacknowledged unicast packets are converted into uni-broadcast messages and sent
through the network. All nodes see the message and populate their routing tables accordingly.
When the destination node is reached, it sends a route response message via the shortest path. The
intermediate nodes see this message and populate their routing tables in the reverse direction, thus reestablishing the route.
The default setting is disabled.
Delete Received Channel List – Remote Radios Only
This parameter deletes the existing zone channel list and uses the configured zone channel allocation
setup with Zone Setup on page 101 until it re-registers with the base station and receives the new
distributed zone channel list.
GENERAL
Frequency Tracking
Frequency Tracking enables the receiver to track any frequency drift in the transmitter to maintain
optimum SNR and radio link performance over the full temperature range.
When enabled, remote stations adjust their receive frequency to the frequency of the incoming packet
rate and the base station notifies remote stations if their transmit frequency requires adjustment.
The default setting is Enabled.

renamed to be able to identify the radio it was saved from.
Save to Radio USB
This saves the file with a filename of ‘asrcfg_1.0.0’ to a binary
encrypted file on the radio USB flash drive root directory.
Restore from PC
This restores all user configuration settings from a binary
encrypted file on a PC directory to the radio.
A reboot warning message will warn of a pending reboot after the
PC file is selected. Clicking OK will open a browser file selection
window to select the file.
Note: If you are using Explorer, it must be IE10 or above for this

Action
Option
Load and Execute
This loads and executes configuration script files.
There are sample configuration script files on the product CD in a
directory called ‘Master Configuration’.
The purpose of these files is to use as templates to create your
own configuration scripts.
Note: Be careful using this feature as incompatible configurations
will change the radios settings and break radio connectivity.
Note: Activating this function will over-write all existing configuration settings in the radio (except for the
non-saved settings e.g. security passwords, licence keys etc) without any verification of the command
setting in the radio. Precautions should be taken to prevent radio outages with incorrect radio
configurations. The following process steps are recommended:
a.
Save the current radio configuration to a PC or USB before uploading the new configuration script
file
b.
Upload the new configuration script file to the radio
c.
If for some reason the radio doesn’t work as expected, the saved configuration file can be
uploaded to the radio (roll back to previous configuration).
Retain IP Address
This parameter when enabled ensures that the radio IP address is not changed when the radio
configuration settings are restored from a configuration file with a different IP radio address. It prevents
the radio losing connectivity when the configuration settings are restored from a configuration file.
Revert Config if Connection Lost
When the Maintenance Files feature is used on remote radios from the base station, this parameter allows
the configurations to be restored to the previous configuration if the connection is lost.
This must be set before executing the Configuration Settings / Configuration Script restore functions.

Start Transfer
This parameter when activated distributes (broadcasts) the new Software Pack to all remote stations in
the network.
Note: The distribution of software to remote stations does not stop customer traffic from being
transferred. However, due to the volume of traffic, the software distribution process may affect customer
traffic.
Software distribution traffic is classified as ‘management traffic’ but does not use the Ethernet
management priority setting. Software distribution traffic priority has a fixed priority setting of ‘very
low’.
To distribute software to remote stations:
This process assumes that a Software Pack has been loaded into the base station with the file transfer
process (see ‘Software > File Transfer’ on page 212).
1. To ensure that the Network Table is up to date, it is recommended running the node discover function
(see ‘Discover Nodes’ on page 193).
2. Click on ‘Start Transfer’.
Note: This process could take anywhere between 40 minutes and several hours depending on channel size,
Ethernet Management Priority setting and the amount of customer traffic on the network.
3. When the distribution is completed, activate the software with the Remote Software Activation.
Pause Transfer
This parameter when activated, pauses the distribution process and shows the distribution status. The
distribution process will continue from where it was paused with Resume Transfer.
Cancel Transfer
This parameter when activated, cancels the distribution process immediately.

ARP Table
This page displays the current Address Resolution Protocols (ARP) on the radio. The radio implemented
ARP protocol is used for resolution of network layer addresses into link layer addresses. It is used to map a
IPv4 address to an Ethernet MAC address. The ARP table shows the results of the ARP protocol linkage
between IPv4 address and Ethernet MAC address of the devices attached to the radio.
In a layer 2 bridge LAN, an upper layer protocol may include the IP address of the destination, but since it
is an Ethernet LAN network, it also needs to know the destination MAC address. First, the radio uses a
cached ARP table to look up the IPv4 destination address for the matching MAC address records. If the
MAC address is found, it sends the IPv4 packet encapsulated in Ethernet frame with the found MAC
address. If the ARP cache table did not produce a result for the destination IPv4 address, the radio sends a
broadcast ARP message requesting an answer (of MAC address that matches) for IP address. The
destination device responds with its MAC address (and IP). The response information is cached in radios’
ARP table and the message can now be sent with the appropriate destination MAC address.

Ethernet MAC Learning Table
This page displays the current Ethernet Media Access Control (MAC) Address table on the radio LAN
network. In order for the radio to switch frames between Ethernet LAN ports efficiently, the radio layer 2
bridge maintains a MAC address table. When the radio bridge receives a frame, it associates the MAC
address of the sending network device with the LAN port on which it was received.
The bridge dynamically learns and builds the MAC address table by using the MAC source address of the
frames received. When the radio bridge receives a frame for a MAC destination address not listed in its
address table, it floods the frame to all LAN ports of the same LAN (or in case of VLAN, to the specific

In-Service Commissioning
Before You Start
When you have finished installing the hardware, RF and the traffic interface cabling, the system is ready
to be commissioned. Commissioning the radio is a simple process and consists of:
1. Powering up the radios.
2. Configuring all radios in the network using SuperVisor.
3. Aligning the antennas.
4. Testing that the links are operating correctly.
5. Connecting up the client or user interfaces.
What You Will Need

Appropriately qualified commissioning staff at both ends of each link.

Safety equipment appropriate for the antenna location at both ends of each link.

Communication equipment, that is, mobile phones or two-way radios.

SuperVisor software running on an appropriate laptop, computer, or workstation at the base
station radio.

Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters.

Predicted receiver input levels and fade margin figures from the radio link budget.
Aprisa SRi User Manual 1.0.0
In-Service Commissioning | 259
Antenna Alignment
A base station omni-directional collinear antenna has a vertical polarization. The remote station yagi
antennas must also have vertical polarization.
Aligning the Antennas
Align the remote station yagi antennas by making small adjustments while monitoring the RSSI. The Aprisa
SRi has a Test Mode which presents a real time visual display of the RSSI on the front panel LEDs. This can
be used to adjust the antenna for optimum signal strength (see ‘Test Mode’ on page 39).
Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They
should always be panned horizontally to find the peak signal.
1. Press and hold the TEST button on the radio LED panel until all the LEDs flash green (about 3 - 5
seconds).
Note: The time for the LEDs to display the RSSI result is variable, depending on the network traffic,
and can be up to 5 seconds. Small antenna adjustments should be made and then wait for the display
to refresh.
2. Move the antenna through a complete sweep horizontally (pan). Note down the RSSI reading for all the
peaks in RSSI that you discover in the pan.
3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan.
Move the antenna horizontally slightly to each side of this maximum to find the two points where the
RSSI drops slightly.
4. Move the antenna halfway between these two points and tighten the clamp.
5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (tilt)
vertically. Note down the RSSI reading for all the peaks in RSSI that you discover in the tilt.
6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt.
Move the antenna slightly up and then down from the maximum to find the two points where the RSSI
drops slightly.
7. Move the antenna halfway between these two points and tighten the clamp.
8. Recheck the pan (steps 2-4) and tighten all the clamps firmly.
9. To exit Test Mode, press and hold the TEST button until all the LEDs flash red (about 3 – 5 seconds).

USB Serial Ports
USB RS-232 / RS-485 Serial Port
The Aprisa SRi USB host port is predominantly used for software upgrade and diagnostic reporting.
However, it can also be used to provide an additional RS-232 DCE or RS-485 serial port for customer
traffic.
This is accomplished with a USB to RS-232 / RS-485 serial converter cable. This plugs into the USB host
port
connector and can be terminated with the required customer connector.
This additional RS-232 / RS-485serial port is enabled with the SuperVisor mode setting in Serial Port
Settings (see ‘Serial > Port Setup’ on page 108).
The Aprisa SRi USB port has driver support for these USB serial converters. Other USB serial converters
may not operate correctly.
USB RS-232 / RS-485 operation
The USB serial converter buffers the received data frames into 64 byte blocks separated by a small interframe gap.
For the majority of applications, this fragmentation of egress frames is not an issue. However, there are
some applications that may be sensitive to the inter-frame gap, therefore, these applications need
consideration.
A 5 ms inter-frame is recommended for the applications that are sensitive to inter-frame gap timings.
On a USB RS-232 port, Modbus RTU can operate up to 9600 bit/s with all packet sizes and up to 115200
bit/s if the packet size is less than 64 bytes. The standard RS-232 port is fully compatible with Modbus RTU
at all baud rates.

Software Upgrade
A software upgrade can be performed on a single Aprisa SRi radio or an entire Aprisa SRi network.
Network Software Upgrade
This process allows customers to upgrade their Aprisa SRi network from the central base station location
without need for visiting remote sites.
The Software Pack is loaded into the base station with the file transfer process (see ‘Software > File
Transfer’ on page 212) and distributed via the radio link to all remote stations.
When all remote stations receive the Software Pack version, the software can be remotely activated on all
remote stations.
To upgrade the entire Aprisa SRi network software:
1. Using File Transfer, load the software pack into the base station (see ‘Software > File Transfer’ on
page 212). The software can be transferred to the radio via an FTP transfer or from a USB flash drive.
The Aprisa SRi network file transfer operation is indicated in base station and remote stations by a
flashing orange AUX LED.
2. Distribute the software to the entire network of remote radios (see ‘Software > Remote Distribution’
on page 220). Note that the distribution process over the air will take some time, depending on RF
and Transfer rate settings.
The Aprisa SRi network software distribution operation is indicated in base station and remote stations
by a flashing orange MODE LED.
Note: The distribution of software to remote stations does not stop customer traffic from being
transferred. However, due to the volume of traffic, the software distribution process may affect
customer traffic.
Software distribution traffic is classified as ‘management traffic’ but does not use the Ethernet
management priority setting. Software distribution traffic priority has a fixed priority setting of ‘very
low’.
3. Activate the software on the entire network of remote radios (see ‘Software > Remote Activation’ on
page 222).
Note: When the new software activates on the remote radios, all link communication from the base
station to the remote will be lost. The base station will attempt to re-establish connectivity to the
remote radios for the new version verification but this will fail. However, when the new software
activates on the remote radios, the remote radio will reboot automatically and link communication
will restore when the base station software is activated.
When the Remote Activation process gets to the ‘Remote Radios On New Version’ step, don’t wait for
this to complete but proceed to step 4.
4. Activate the software on the base station radio (see ‘Software > Manager’ on page 216).
5. When the new software has been activated, remote stations will re-register with the base station. The
remote stations software version can verified with ‘Network Status > Network Table’ on page 246.
6. When the base station restarts with the new software, rediscover the nodes (see ‘Discover Nodes’ on
page 193).
Aprisa SRi User Manual 1.0.0
Maintenance | 267
7. Check that all remote radios are now running on the new software (see ‘Network Status > Network
Table’ on page 246).
Note: The following steps will only be necessary if for some reason steps 1-7 did not operate correctly
or if software activation is attempted before the distribution process ends or the remote radio was off
during steps 1-7 and turns on later. Thus, the following steps will most likely not be required.
8. If step 7 shows that not all remote radios are running the latest software version, restore the base /
master station to the previous software version (see ‘Software > Manager’ on page 216).
9. Attempt to re-establish connectivity to the remote radios that have failed to upgrade by navigating to
and remotely managing the remote radios individually.
10. Navigate to the remote radio history log and review the logs to determine the reason for the failure to
activate the new software version.
11. Take appropriate actions to address the reported issue. If connectivity restores with the failed
remotes, repeat steps 2-7 if required.

Single Radio Software Upgrade
This upgrade process is for upgrading the software on a single Aprisa SRi radio.
File Transfer Method
The Software Pack is loaded into the radio with the file transfer process (see ‘Software > File Transfer’ on
page 212) and activated (see ‘Software > Manager’ on page 216).
The Aprisa SRi upgrade operation is indicated by a flashing orange AUX LED.
To upgrade the Aprisa SRi radio software:
1. Unzip the software release files in to the root directory of a USB flash drive.
2. Insert the USB flash drive into the host port
3. Using File Transfer, load the software pack into the radio (see ‘Software > File Transfer’ on page 212).
4. Remove the USB flash drive from the host port
5. Activate the software on the radio (see ‘Software > Manager’ on page 216).
Aprisa SRi User Manual 1.0.0
Maintenance | 269
USB Boot Upgrade Method
A single Aprisa SRi radio can also be upgraded simply by plugging a USB flash drive containing the new
software into the USB A host port
on the Aprisa SRi front panel and power cycling the radio.
To upgrade the Aprisa SRi radio software:
1. Unzip the software release files in to the root directory of a USB flash drive.
2. Check that the SuperVisor USB Boot Upgrade setting is set to ‘Load and Activate’ (see ‘Software >
Setup’ on page 211).
3. Power off the Aprisa SRi and insert the USB flash drive into the host port
4. Power on the Aprisa SRi.
5. The software upgrade process is complete when the OK LED flashes green. This can take about 2
minutes.
The software will have loaded in to the radio current software version.
6. Remove the USB flash drive from the host port
7. Power cycle the Aprisa SR.
Login to the radio being upgraded and go to SuperVisor ‘Software > Manager’ on page 216.
The version of the uploaded software will be displayed in the Software Pack ‘Version’ field and the
current software version.
If the upgrade process did not start, the Aprisa SRi could already be operating on the version of software
on the USB flash drive. This will be indicated by flashing OK LED and then the OK, MODE and AUX will light
steady green.
If the radio is not operating on the new software (after the power cycle), it could be caused by the
SuperVisor ‘USB Boot Upgrade’ setting set to ‘Load Only’ (see ‘Software > Setup’ on page 211).
In this case, go to SuperVisor see ‘Software > Manager’ on page 216 and tick the Software Pack ‘Activate’
checkbox and click ‘Apply’.
If any Display Panel LED flashes red or is steady red during the upgrade process, it indicates that the
upgrade has failed. This could be caused by incorrect files on the USB flash drive or a radio hardware
failure.
Software Downgrade
Radio software can also be downgraded if required. This may be required if a new radio is purchased for
an existing network which is operating on an earlier software release.
The downgrade process is the same as the upgrade process.

Alarm Types and Sources | 273
12. Alarm Types and Sources
Alarm Types
There are three types of alarm event configuration types:
1. Threshold Type
These alarm events have lower and upper limits. An alarm is raised if current reading is outside the limits.
Note: the limits for PA Current, TX AGC, TX Reverse Power and Thermal shutdown are not user
configurable.
2. Error Ratio Type
This is the ratio of bad packets vs total packets in the defined sample duration.
For Serial, it is the ratio of bad characters vs total characters in the duration seconds. An alarm is raised if
current error ratio is greater than the configured ratio. The error ratio is configured in ‘Upper Limit’ field
and accepts value between 0 and 1. Monitoring of these events can be disabled by setting the duration
parameter to 0.
3. Sample Duration Type
Used for No Receive data events type. An alarm is raised if no data is received in the defined sample
duration. Monitoring of these events can be disabled by setting the duration parameter to 0.
See ‘Events > Events Setup’ on page 199 for setup of alarm thresholds / sample durations etc.

14. Product End Of Life
End-of-Life Recycling Programme (WEEE)
The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment.
Under the Directive, used equipment must be marked, collected separately, and disposed of properly.
4RF has implemented an end-of-life recycling programme to manage the reuse, recycling, and recovery of
waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste
Electrical and Electronic Equipment 2002/96/EC).
The WEEE Symbol Explained
This symbol appears on Electrical and Electronic Equipment (EEE) as part of the WEEE (Waste EEE)
directive. It means that the EEE may contain hazardous substances and must not be thrown away with
municipal or other waste.
WEEE Must Be Collected Separately
You must not dispose of electrical and electronic waste with municipal and other waste. You must
separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE
collection system in your area.
YOUR ROLE in the Recovery of WEEE
By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE
that enters the waste stream.
One of the aims of the WEEE directive is to divert EEE away from landfill and encourage recycling.
Recycling EEE means that valuable resources such as metals and other materials (which require energy to
source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and
manufacturing new products is reduced.
EEE Waste Impacts the Environment and Health
Electrical and electronic equipment (EEE) contains hazardous substances which have potential effects on
the environment and human health. If you want environmental information on the Aprisa SRi radio,
