RF Interface MAC address
This parameter is only applicable when the radio is part of a Protected Station.
This RF Interface MAC address is used to define the MAC address of the Protection Switch. This address is
entered in the factory. Both Protected Station radios read and use this MAC address.
This MAC address entry will only be used by the software if it detects that the factory MAC address set in
the internal EPROM of the protected switch is corrupted for some reason, otherwise the software will
ignore the MAC address entered by the user.
The RF interface MAC address is used for registration process only. For example, in a remote Protected
Station, both radios share the same RF MAC address and a single entry of the remote Protected Station
will be presented in network table (Network Status > Network Table).
The Protection Switch RF Interface MAC address is shown on the Protection Switch label:

In-Service Commissioning | 327
Aprisa SR+ User Manual 1.6.0 PO
8. 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.
328 | In-Service Commissioning
Aprisa SR+ User Manual 1.6.0 PO
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
SR+ 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 44).
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.
The RSSI poll refresh rate can be set with the SuperVisor command ‘Transmit Period’ (see
‘Maintenance > Test Mode’ on page 210).
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).

Protected Station
The Aprisa SR+ Protected Station is fully monitored hot-standby and fully hot-swappable product providing
radio and user interface protection for Aprisa SR+ radios. The RF ports and interface ports from the active
radio are switched to the standby radio if there is a failure in the active radio.
Option Example
Part Number
Part Description
APSQ-R400-SSC-HD-22-ENAA
4RF SR+, PS, 400-470 MHz, SSC, Half Duplex, 2E2S, EN, STD
The Aprisa SR+ Protected Station is comprised of an Aprisa SR+ Protection Switch and two standard Aprisa
SR+ radios mounted in a 2U rack mounting chassis.
All interfaces (RF, data, etc.) are continually monitored on both the active and standby radio to ensure
correct operation. The standby radio can be replaced without impacting traffic flow on the active radio.
The Aprisa SR+ radios can be any of the currently available Aprisa SR+ radio frequency bands, channel
sizes or interface port options.
The Aprisa SR+ Protected Station can operate as a base station, repeater station or remote station. The
protection behaviour and switching criteria between the active and standby radios is identical for the
three configurations.
By default, the Aprisa SR+ Protected Station is configured with the left hand radio (A) designated as the
primary radio and the right hand radio (B) designated as the secondary radio.
Each radio is configured with its own unique IP and MAC address and the address of the partner radio.
On power-up, the primary radio will assume the active role and the secondary radio will assume the
standby role. If, for some reason, only one radio is powered on it will automatically assume the active
role.
Both the Aprisa SR+ Protected Station primary radio and secondary radio must be operating on the same
software version.
Product Options | 331
Aprisa SR+ User Manual 1.6.0 PO
Protected Ports
The protected ports are located on the protected station front panel. Switching occurs between the active
radio ports and the standby radio ports based on the switching criteria described below.
The protected ports include:
Antenna ports ANT/TX and RX (if dual antenna ports used)
Ethernet ports (depending on interface port option purchased)
Serial ports (depending on interface port option purchased)
Operation
In hot-standby normal operation, the active radio carries all RS-232 serial and Ethernet traffic over the
radio link and the standby radio transmit is on with its transmitter connected to an internal load. Both
radios are continually monitored for correct operation including the transmitter and receiver and alarms
are raised if an event occurs.
The active radio sends regular ‘keep alive’ messages to the standby radio to indicate it is operating
correctly. In the event of a failure on the active radio, the RF link and user interface traffic is
automatically switched to the standby radio.
The failed radio can then be replaced in the field without interrupting user traffic.
Switch Over
The switch-over to the standby radio can be initiated automatically, on fault detection, or manually via
the Hardware Manual Lock switch on the Protection Switch or the Software Manual Lock from SuperVisor.
Additionally, it is possible to switch-over the radios remotely without visiting the station site, via the
remote control connector on the front of the Protection Switch.
On detection of an alarm fault the switch-over time is less than 0.5 seconds. Some alarms may take up to
30 seconds to be detected depending on the configuration options selected.
The Protection Switch has a switch guard mechanism to prevent protection switch oscillation. If a switch-
over has occurred, subsequent switch-over triggers will be blocked if the guard time has not elapsed.
The guard time starts at 20 seconds and doubles each switch-over to a maximum of 320 seconds and
halves after a period of two times the last guard time with no protection switch-overs.
332 | Product Options
Aprisa SR+ User Manual 1.6.0 PO
Switching Criteria
The Protected Station will switch-over operation from the active to the standby radio if any of the
configurable alarm events occur, or if there is a loss of the ‘keep alive’ signal from the active radio.
It is possible to configure the alarm events which will trigger the switch-over. It is also possible to prevent
an alarm event triggering a switch-over through the configuration of blocking criteria.
Any of the following alarm events can be set to trigger or prevent switching from the active radio to the
standby radio (see ‘Events > Events Setup’ on page 224).

Configuration Management
The Primary and Secondary radios are managed with the embedded web-based management tool,
SuperVisor, by using either the Primary or Secondary IP address. Configuration changes in one of the radios
will automatically be reflected in the partner radio.
To ensure all remote stations are registered to the correct (active) base station, changes to the Network
Table are automatically synchronized from the active radio to the standby radio. The Network Table is
only visible on the active radio. This synchronization does not occur if the Hardware Manual Lock is active.
Product Options | 335
Aprisa SR+ User Manual 1.6.0 PO
Hardware Manual Lock
The Hardware Manual Lock switch on the Protection Switch provides a manual override of the active /
standby radio.
When this lock is activated, the selected radio (A or B) becomes the active radio regardless of the
Software Manual Lock and the current switching or block criteria.
When the lock is deactivated (set to the Auto position), the protection will become automatic and
switching will be governed by normal switching and blocking criteria.
The state of the switch is indicated by the three LEDs on the Protection Switch:
A LED
B LED
Locked LED
State
Green
Off
Off
Auto - Radio A is active
Off
Green
Off
Auto - Radio B is active
Green
Off
Orange
Manual Lock to radio A
Off
Green
Orange
Manual Lock to radio B
The Protection Switch also has a Software Manual Lock. The Hardware Manual Lock takes precedence over
Software Manual Lock if both diagnostic functions are activated i.e. if the Software Manual Lock is set to
‘Primary’ and the Hardware Manual Lock set to ‘Secondary’, the system will set the Secondary radio to
Active.
When a Hardware Manual Lock is deactivated (set to the Auto position), the Software Manual Lock is re-
evaluated and locks set appropriately.
Remote Control
The switch-over to the standby radio can be initiated via the Remote Control connector on the front of the
Protection Switch. This control will only operate if the Hardware Manual Lock switch is set to the Auto
position.
The inputs are logic inputs with 4700 Ω pullup to +3.3 VDC. They require a pull down to ground to activate
the control. The ground potential is available on the connector (see ‘Protection Switch Remote Control
Connections’ on page 367).

L2 / L3 Protection Operation
The Aprisa SR+ Protected Station has selectable L2 Bridge or L3 Router modes, with VLAN, QoS and L2/3/4
address filtering attributes. Each Radio is configured with its own unique IP and MAC address and partner
radio address. On switch-over failure, the new active radio sends out a gratuitous ARP to update the MAC
learning tables / ARP tables of upstream bridge/router for appropriate traffic flow.
Hot-Swappable
The two Aprisa SR+ radios are mounted on a pull-out tray to making it possible to replace a failed radio
without interrupting user traffic.

Creating a Protected Station
When a Protected Station is ordered from 4RF, it will be delivered complete with radios installed, pre-
cabled and pre-configured for Redundant operation. The following process will not be required.
This process is to create a protected station from two individual SR+ radios and a new spare Aprisa SR+
Protection Switch. It assumes that the SR+ radios are currently setup for non-protected operation.
1. Set the protection type and partner IP address of the SR+ radio A with SuperVisor 'Terminal >
Operating Mode'. Set this radio Protection Unit to primary.
2. Set the protection type and partner IP address of the secondary SR+ radio B with SuperVisor Terminal
> Operating Mode'. Set this radio Protection Unit to secondary.
3. Switch off the radios and place the two radios in the new spare Aprisa SR+ Protection Switch.
4. Ensuring that the cables are not crossed over, plug in the interface port cables, the Alarm and Protect
port cables and the power connector to both the radios. Secure the power connectors with the two
screws.
5. Power on the Protected Station.
6. Connect to either one of the radios via SuperVisor. This will start up SuperVisor in Single Session
Management mode.
7. The user can now configure the Protected Station as required.
Replacing a Protected Station Faulty Radio
Replacing a faulty radio in a Protected Station can be achieved without disruption to traffic.
Assuming that the primary radio is active and the secondary radio is faulty and needs replacement:
1. Ensure the replacement radio has the same version of software installed as the primary radio. If
necessary, upgrade the software in the replacement radio.
2. Set the RF Interface MAC Address (see ‘Protected Station: Maintenance > Advanced’ on page 300).
This MAC address is present on chassis label.
3. Using SuperVisor > Maintenance > Advanced ‘Save Configuration to USB’ and ‘Restore Configuration
from USB’ operation, clone the primary radio’s configuration to the replacement radio.
4. Configure the replacement radio as the secondary radio and setup the IP address and other protection
parameters (see ‘Terminal > Operating Mode’ on page 94).
5. Set the Hardware Manual Lock switch to make the primary radio active.
6. Unplug the interface port cables, the Alarm and Protect port cables and the power connector from the
faulty radio being replaced. The two screws securing the power connector will need to be undone.
7. Carefully remove the faulty radio from the protection switch.
8. Install the replacement radio into the protection switch.
9. Ensuring that the cables are not crossed over, plug in the interface port cables, the Alarm and Protect
port cables and the power connector to the replacement radio. Secure the power connector with the
two screws.
10. Power on the replacement radio and wait for it to become standby.
11. Set the Hardware Manual Lock switch to the Auto position.
Product Options | 345
Aprisa SR+ User Manual 1.6.0 PO
Replacing a Faulty Power Supply
Replacing one of the power supplies can be achieved without disruption to traffic.
If a power supply has failed, the associated radio will have failed which will have caused the protection
switch to switch-over to the other radio. It will not have switched back unless the power was restored and
another problem occurred which caused a switch-over.
1. If the A power supply is faulty, ensure that the B radio is active (whether it be the primary or
secondary radio).
If the B power supply is faulty, ensure that the A radio is active (whether it be the primary or
secondary radio).
2. Replace the faulty power supply.
Replacing a Faulty Protection Switch
Note: Replacing a faulty Protection Switch will disrupt traffic.
Move the radios, the interface cables and the power cables to the replacement Protection Switch.
On both Protected Station radios:
1. Power on the radio and wait for it to become ready.
2. Using SuperVisor > Maintenance > Advanced, enter the RF Interface MAC address shown on the
Protection Switch label (see ‘Protected Station: Maintenance > Advanced’ on page 300).
3. Using SuperVisor > Maintenance > Advanced, Decommission the node (see ‘Decommission Node’ on
page 218) and then Discover the Nodes (see ‘Discover Nodes’ on page 218).
Ensure that the Hardware Manual Lock switch is set to the Auto position.
The Aprisa SR+ Protected Station is now ready to operate.

Data Driven Protected Station
The Aprisa SR+ Data Driven Protected Station provides radio and RS-232 serial port user interface
protection for Aprisa SR+ radios.
Example Part:
Part Number
Part Description
APSQ-D400-SSC-HD-22-ENAA
4RF SR+, PD, 400-470 MHz, SSC, Half Dup, 2E2S, EN, STD
The Aprisa SR+ Data Driven Protected Station shown is comprised of two standard Aprisa SR+ setup as
‘dual antenna port’, ‘half duplex’ radios and two external duplexers mounted on 19" rack mounting
shelves.
The Aprisa SR+ radios can be any of the currently available Aprisa SR+ radio frequency band options.
By default, the Aprisa SR+ Data Driven Protected Station is configured with the left hand radio (A)
designated as the primary radio and the right hand radio (B) designated as the secondary radio.
Each radio is configured with its own unique IP and MAC address and the address of the partner radio.
On power-up, the primary radio will assume the active role and the secondary radio will assume the
standby role. If, for some reason, only one radio is powered on it will automatically assume the active
role.
Operation
The active radio is determined explicitly by which radio receives data on its RS-232 serial port input from
the interface.
The active radio carries all RS-232 serial traffic over its radio link and the standby radio is unused with its
transmitter turned off.
If data is received on the RS-232 serial port interface input of the standby radio, it will immediately
become the active radio and the radio which was active will become the standby radio.
Over The Air Compatibility
If the Aprisa SR+ Data Driven Protected Station is to be used in a network of New Aprisa SR radios, the ‘SR
Compatible’ option must be enabled (see ‘SR Compatible’ on page 95).
Product Options | 347
Aprisa SR+ User Manual 1.6.0 PO
Switch Over
The active radio is determined explicitly by which radio receives data on its RS-232 serial port.
The switching and blocking criteria used for the standard Protected Station do not apply. This means that
events and alarms on the unit are not used as switching criteria.
Configuration Management
The Primary and Secondary radios are managed with the embedded web-based management tool,
SuperVisor (see ‘Managing the Radio’ on page 67) by using either the Primary or Secondary IP address.
Configuration changes in one of the radios will automatically be reflected in the partner radio.
Changes to the Network Table are automatically synchronized from the active radio to the standby radio
but the Network Table is only visible on the active radio.
Power
A +10.5 to +30 V DC external power source must be connected to both the A and B Phoenix Contact 2 pin
male power connectors. The maximum combined power consumption is 42 Watts for 10 W transmit peak
power.

USB RS-232 / RS-485 Serial Port
The Aprisa SR+ 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 124).
The Aprisa SR+ 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 inter-
frame 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 SR+ radio or an entire Aprisa SR+ network.
Network Software Upgrade
This process allows customers to upgrade their Aprisa SR+ 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 238) 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.
Non-Protected Network Upgrade Process
This upgrade process is for upgrading the software on an entire Aprisa SR+ network from a non-protected
base station. If there are protected remotes in the network, they must be locked to the current active
radio.
To upgrade the entire Aprisa SR+ network software:
1. Using File Transfer, load the software pack into the base station (see ‘Software > File Transfer’ on
page 238). The software can be transferred to the radio via an FTP transfer or from a USB flash drive.
The Aprisa SR+ 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 246). Note that the distribution process over the air will take some time, depending on RF
and Transfer rate settings.
The Aprisa SR+ 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 248).
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.
Maintenance | 359
Aprisa SR+ User Manual 1.6.0 PO
4. Activate the software on the base station radio (see ‘Software > Manager’ on page 242).
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 271.
6. When the base station restarts with the new software, rediscover the nodes (see ‘Discover Nodes’ on
page 218).
7. Check that all remote radios are now running on the new software (see ‘Network Status > Network
Table’ on page 271).
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 242).
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.

Protected Network Upgrade Process
This upgrade process is for upgrading the software on an entire Aprisa SR+ network from a protected base
station. This software upgrade can be achieved without disruption to traffic.
Transferring the new software to the radios
The software can be transferred to the radio via an FTP transfer or from a USB flash drive.
1. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 335), or the Software
Manual Lock (see ‘Lock Active To’ on page 295), force the secondary radio to active
2. Using File Transfer, load the software pack into the secondary radio (see ‘Protected Station: Software
> Secondary File Transfer’ on page 310).
3. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 313).
4. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 335), or the Software
Manual Lock (see ‘Lock Active To’ on page 295), force the primary radio to active.
5. Using File Transfer, load the software pack into the primary radio (see ‘Protected Station: Software >
Primary File Transfer’ on page 307).
6. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 313).
7. Distribute the software to the entire network of remote radios (see ‘Protected Station: Software >
Remote Distribution’ on page 315). If there are protected remotes in the network, they must be
locked to the current active radio.
Note that the distribution process over the air will take some time, depending on RF and Transfer rate
settings.
Activating the new software on the radios
1. Activate the software on the entire network of remote radios (see ‘Protected Station: Software >
Remote Activation’ on page 318).
2. Monitor the progress of the activation process until the stage where activation of all remote radios has
been confirmed.
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 271.
3. If the new software version is not over the air compatible with the version currently operating on the
radio, there is no need to wait as all link communication from the base station to the remote will be
lost so the verification of the new version on the remote radio will fail.
4. Activate the new version software pack of the secondary radio (see ‘Protected Station: Software >
Manager’ on page 313).
5. Immediately after that, activate the new version software pack of the primary radio (see ‘Protected
Station: Software > Manager’ on page 313).
Note that the activation process will take a few minutes.

Single Radio Software Upgrade
This upgrade process is for upgrading the software on a single Aprisa SR+ radio.
Note: If a radio has been configured for a Protection Type of ‘Redundant’, and that radio is no longer part
of a Protected Station, the Protection Type must be changed to ‘None’ before the radio software upgrade
can be achieved.
File Transfer Method
The Software Pack is loaded into the radio with the file transfer process (see ‘Software > File Transfer’ on
page 238) and activated (see ‘Software > Manager’ on page 242).
The Aprisa SR+ upgrade operation is indicated by a flashing orange AUX LED.
To upgrade the Aprisa SR+ 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 238).
4. Remove the USB flash drive from the host port .
5. Activate the software on the radio (see ‘Software > Manager’ on page 242).
Maintenance | 363
Aprisa SR+ User Manual 1.6.0 PO
USB Boot Upgrade Method
A single Aprisa SR+ 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 SR+ front panel and power cycling the radio.
To upgrade the Aprisa SR+ 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 237).
3. Power off the Aprisa SR+ and insert the USB flash drive into the host port .
4. Power on the Aprisa SR+.
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 242.
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 SR+ 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 237).
In this case, go to SuperVisor see ‘Software > Manager’ on page 242 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
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.

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 SR+ radio,
