1.0 INTRODUCTION TO THE VLB-92 OMNI MEGA LED MARINE BEACON
WARNING
THIS OMNI MEGA BEACON IS CAPABLE OF PRODUCING VERY HIGH INTENSITY LIGHT OF
OVER 200,000 CANDELAS. THE BEACON’S VERTICAL DIVERGENCE IS ±0.8 DEGREES. IT
IS RECOMMENDED THAT OPERATORS DO NOT LOOK DIRECTLY INTO THE BEAM.
This LED PRODUCT has been tested to IEC60825-1 and found to be exempt from
classification.
THIS OMNI MEGA BEACON MAY BECOME HOT TO THE TOUCH.
1.1 Overview
Each VLB-92 Omni Mega is supplied for a particular application depending on the colour, flash
character and range required. As such the number of lenses required will vary even though the
range may be the same for different applications. The details of the application for this Omni Mega
Beacon are provided on the cover of this manual.
The number of lenses required for any application is determined from the peak intensity of the
flash character and the thermal constraints of the LED’s in the Omni Mega design. Longer on
period within a flash character and lower duty cycle will minimise the number of lenses required
and consequently the cost of the Omni Mega Beacon.
The VLB-92 Omni Mega is available in two supply voltage options for operation from nominal
12VDC or 24VDC supplies. The peak and average night currents as well as the day and night off
currents of the beacon are detailed in Appendix B of this manual.
As the VLB-92 Omni Mega is delivered against the application specification there should be no
need to alter the program settings. Installation should only involve the assembly/mounting and the
supply of power. If an external light sensor is required this will need to be connected to the
beacon.
If required the intensity can be adjusted according to the capabilities and settings detailed in
Appendix B.
The Omni Mega requires a high level of current in order to meet the range specification of the
application. Care should be taken to size the electrical cabling so that the voltage supplied to the
beacon is within specification. With any cable size calculation remember to account for the total
length of the electrical circuit. Where possible, keep the length of DC cabling within a few metres.
To minimise cable inductance the supply cables should be straight and strapped together.
1.2 Performance at a Glance
This Omni Mega has been supplied to meet the requirements on the sales order.
As a product the Omni Mega has the following specification:
•Nominal Night range of 17 to 23.5Nm for the 1.6 degree version, at an atmospheric
transmission of 0.74T (10Nm visibility) depending on the colour, flash character and the
number of lenses used.
•Automatic Schmidt Clausen intensity correction for flash characters
•Vertical Divergence is better than 1.6 degrees, as appropriate, at 50 percent of the peak
intensity.
•Hard-wire synchronising (negative transition)
•RS232 (or RS485) and IRDA data ports
•Hard wire control and monitoring connections including inputs for operation override, and
outputs for alarm, beacon healthy, and LEDs on

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 8 of 56 VLB-92 V1.19
•Programmed with Vega TVIR programmer and Vega Prog-03 IRDA computer program kit.
•The Omni Mega has a 15-year design life
1.3. Construction
The metal components of the VLB-92 Omni Mega are made from cast or machined marine grade
aluminium. All aluminium components are anodised and the cast components are painted in a
marine grade undercoat and two-part gloss final coat. The LED lenses are made from machined
cast acrylic. Cooling of the LED’s is achieved using multiple heat pipes in the central core to
transfer the heat to the heat sink mounted on top of the beacon.
The VLB-92 Omni Mega is sealed against dust and moisture to the level of IP-67. There should be
no need for the beacon to be opened during its design life. The Omni Mega is fully sealed. There
is no breather vent.
1.4 Other Options
The VLB-92 Omni Mega operation can be enhanced using the following Vega products
•GPS synchronisation using the Vega VSU-29 GPS synchronisation unit
•Monitoring using the Mini VegaWeb Internet based monitoring system (requires VLB-92
firmware version 029 or later. New firmware can be loaded into a beacon in the field –
contact Vega for details.).
2.0 MECHANICAL ASSEMBLY AND INSTALLATION
2.1 Assembly
For Omni Mega bigger than a three-lens unit the separate parts will need to be assembled by
bolting parts together and connecting the cables. The Omni Mega is shipped in this format to
spread the shipping weight across a number of items and to allow the light to be more easily
transported to where it will be used.
The separate parts should be bolted together as shown in Appendix F.

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 9 of 56 VLB-92 V1.19
2.2 Lifting Eye
VLB-92 Omni Mega will be delivered with a lifting eye that can be attached to each section of the
light to allow easy handling. It should be used with the components of the Omni Mega as delivered
from Vega. Do not use the lighting eye on anything more than a single unit assembly. The lifting
eye is not designed to lift an assembled Omni Mega over the size of single unit. The intention is to
lift the component parts to the assembly location. Ensure the lifting eye is removed after the Omni
Mega is installed to ensure the sealing integrity of the beacon.
2.3 Bird Spikes
The VLB-92 Omni Mega is supplied with 28 stainless steel bird spikes to be screwed into the top of
the beacon.

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 10 of 56 VLB-92 V1.19
2.4. Mounting Omni Mega
The mounting base of the Omni Mega contains 14mm holes for three or four bolt mounting on a
200mm diameter circle. The mounting holes contain corrosion isolation inserts to prevent
corrosion occurring between the base and the mounting bolts. Do not over tighten the mounting
bolts as the corrosion isolators will compress and this will cause metal-to-metal contact between
the base and the bolt.
As the focal plane for the beacon is parallel to the base, the mounting surface needs to be level to
ensure the Omni Mega has a horizontal beam. This can be checked by placing a builder’s level on
the mounting surface then moving the level 90 degrees at a time checking the surface is level in at
least two directions. If the mounting surface is not level take appropriate measures to ensure it is
before permanently fixing the Sector Light in place.
2.5 The Mounting Structure
Any sway of the mounting structure needs to be constrained to a level where the Omni Mega can be
visible to the intended user.
For the 1.6 degree Omni Mega beacon: The vertical divergence of the beacon is 1.6 degrees. At ±
0.8°the intensity is at 50%, and at ± 1.6°the intensity is approximately 10% of the peak intensity.
3.0. ELECTRICAL CONNECTION
3.1 Power Connection
The VLB-92 Omni Mega is available in 12VDC and 24VDC models. The correct model must be
requested at the time of ordering. A beacon cannot be converted from one voltage type to another.
The beacon must never be connected to any voltage over 36.0VDC. The Omni Mega will shut
down to protect its electronics if the input voltage is outside the rated voltage range listed in
Appendix J.
The 1.5m power cable supplied with the Omni Mega has either a 6mm2or 10mm2copper
conductor. This size cable is adequate where the distance to the supply is 5m or less. Where the
distance is greater than 5m the cable should be sized to allow no more than a 5% voltage
reduction when carrying the peak beacon current over the entire length of the electrical circuit.
Connections to the Beacon are as shown below.

3.2 Other Connections to the Omni Mega
All other connections to the Omi Mega beacon are through a single multi pin connector fitted to the
base of the beacon. A plug and 1.5m of connection cable is supplied with the beacon. The
connection diagrams of the connector and cable are shown in Appendix E. The electrical
specification is provided in the specifications section of this manual.
3.2.1 Hardwire Synchronization
The Vega hardwire sync operatesas a positive to negative transition. The start ofthe flash character
can be delayed between 0 and 9.9 seconds should it be desirable to have a different start time to
other beacons connected to the synchronising wire.
Where GPS synchronisation is required the Vega VSU-29 GPS sync unit can be connected to the
synchronising wire of the Omni Mega. Alternatively a GPS sync pulse can be generated from a
VegaWeb monitoring unit when it is fitted with a GPS unit.
Other beacon manufacturers may not use a negative transition signal and will not be able to
synchronise with Vega Beacons. If there is a requirement to synchronise with beacons with a
positive transition signal it may be possible to use the signal inverter module (Vega 167-295). The
Omni Mega will only operate in Slave Sync mode when connected to the signal inverter module.
Vega 12V products that generate or receive hard-wired sync, such as the VSU-29 and the VLB-44,
etc, can be safely connected to the sync wire on the Omni Mega.
3.2.2 Omni Mega Monitor.
The Omni Mega monitor outputs consists of a normally-open (NO) and normally-closed (NC)
contact that are used to provide an indication when the Omni Mega is able to operate or not able to
operate. This alarm monitors the current and the supply voltage as well as internal functioning of
the beacon. These contacts are electrically isolated from the power supply and the rest of the
beacon circuitry.
The two output signals, Beacon FAIL and Beacon OK, are always in opposite states from each
other. A relay contact is provided for each signal and they share a common contact.
The Beacon FAIL relay contact is closed to the common when the Omni Mega is in any of the
following states:
•For a few seconds at first power-up.
•No voltage or low voltage is present.
•No LED current or low current is detected when the Omni Mega LED’s should be on.
•Alarm is being tested using Operation mode 1-5-007 (Clause 5.5.6).
To use the Beacon FAIL and/or Beacon OK signals, first connect the common signal to a supply
rail, e.g. battery negative. A voltage from 0 to 30VDC can be applied to these contacts. The
maximum current the outputs can handle is 2A and an open circuit maximum voltage of 30VDC.
For additional details refer to the specification section.
3.2.3 Omni Mega “Beacon ON” Output
The Omni Mega ”Beacon On” output is a solid-state relay and will operate when the beacon is
awake and the LEDs are on. Please note that the relay will not follow the flash character. It will be

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 12 of 56 VLB-92 V1.19
on when flash characters are being generated. A normally open relay contact pair is provided and
is isolated from all other circuitry in the beacon.
The Beacon On relay contacts will be closed when:
•The flash character is being generated according to the programmed settings of the Omni
Mega and no fault is detected.
•When the Omni Mega is forced on by the “Beacon On” input.
The Beacon On relay contacts will be open when:
•The Omni Mega flashes its LEDs during, or on leaving, programming mode.
•Any alarm detection state that turns off the LEDs and activates the Beacon FAIL output.
•The beacon is in an off state due to either day detection, if in night mode only, or is forced
off by the “Beacon Off” input.
A voltage from 0 to 30VDC can be applied to the “Beacon On” output. The maximum current the
monitor output can handle is 125mA DC. For additional details refer to the specification section.
3.2.4 Omni Mega Force inputs: Beacon On and Beacon Off
The Omni Mega Force inputs for “ON” and “OFF” will force the beacon into the selected state
regardless of the programmed operation and day/night detection status. When “Forced ON”, the
Omni Mega will flash the programmed flash character and night intensity.
If both force inputs are operated at the same time the inputs will be ignored and the Omni Mega
will operate according to its programmed parameters.
A voltage from 0 to 30VDC can be applied to the Beacon ON and beacon OFF inputs. An input
voltage of 6V or more will activate an input. An open-circuit input will be inactive. For additional
details refer to the specification section.
3.2.5 Data Port
The RS232 (or RS485) data port is continuously operational. Beacon commands that correspond
to those offered via the TVIR Remote will be accepted on the Data port’s serial input at any time.
Additionally, the beacon will output any error status on the Data port’s serial output.
The Data port can be enabled to send monitoring data either on-demand or continuously. The
command input function will continue to be available when monitoring is enabled.
Details of the data port protocol and the beacon parameters available via this protocol are
contained in Appendix G.

4.0 INITIAL POWER UP
4.1 Initial Power up and Alignment
The beacon works as a single light irrespective of the number of units used in the assembly.
The beacon is shipped with factory settings that meet the customer’s requirements of range, flash
character, etc. The beacon can be returned to these factory default settings at any time by sending
the Reset Factory Default 8-1-000 command.
The programming features of the Omni Mega will be covered later in the manual.
At power-on when the supply voltage is first connected, the Omni Mega will remain inactive for up
to 30 seconds and the Beacon FAIL output will be asserted during this time. Subsequently, the
beacon will start in night mode with the beacon flashing with the programmed flash character and
the Beacon FAIL signal will be de-asserted.
•After a further 10 seconds the beacon will begin to monitor the ambient light level. If day is
detected, and the beacon is programmed in night-only mode, the LED’s will be turned off.
•After 14 seconds the beacon will begin to monitor the voltage for the low threshold (factory
setting of 20.0 Volts for the 24V version or 10.0V for the 12V version). If the threshold is
reached the Omni Mega will be turned off. The beacon will not return to normal operation
again until the supply voltage rises to above the high threshold (25.6 volts for the 20V
version or 12.8 volts for the 12V version). Recycling the power to the Omni Mega will reset
the low voltage cut out operation.
Note: If the supply terminals (+ / -) are connected in reverse the Omni Mega will not power up. No
damage will be caused by reverse connecting the beacon.
5.0 PROGRAMMING
5.1 Programming Methods
There are two recommended methods of programming the Omni Mega:
•Using the Vega remote TVIR Programmer (Remote-02);
•Using a Computer with the VLB-92 IRDA Programming Kit (Prog-03).
Advanced users may also program the Omni Mega via the Data port serial input.
The Beacon will be shipped with a default setting for programming with the Remote TVIR
Programmer. The IRDA data port will need to be enabled to allow computer IRDA programming.
5.1.1 Using the Vega Remote TVIR Programmer
The location of the TVIR sensor in the Omni Mega is shown in the diagram below. For best results
the TVIR programmer should be used at this point on the Omni Mega.
Numeric keypad, used
to configure the
programmable
features of the light.
Red standby key, used to
enter programming mode.
IMPORTANT
Before attempting to use the Programmer for
the first time, please pull the plastic insulating
strip out of the battery holder –you do not
need to remove the battery holder to do this.
The programmer will not work if the plastic
strip is left in place.

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 14 of 56 VLB-92 V1.19
During programming the Omni Mega will provide visual feedback by flashing as the keys are
operated on the TVIR programmer. On completion of a program option the beacon will provide
visual feedback by repeating the code of the programmed function by a series of flashes.
Because of the high intensity of the Omni Mega and the corresponding risk to the eyes of the
programmer a green LED is used to provide the visual feedback as programming is carried out.
This is the default feedback option for TVIR programming and the main LEDs of the Omni Mega
will be turned off when the beacon is in programming mode. The green LED is located at the
same point as the TVIR sensor. If the green LED cannot be seen because of high daylight
intensity there is an option to use the main LEDs in the Omni Mega to provide the programming
feedback. When used during programming the intensity of the beacon LED’s will be 4% of the
maximum possible intensity.
5.1.2 Using a Computer
Computer programming can be carried out using the RS232 (or RS485) or the IRDA data port.
The RS232 port is always switched on in the Omni Mega. Two-way IRDA communication to the
Beacon can be provided via a USB to infrared adapter plugged into the computer. The IRDA must
be turned on using the TVIR programmer to become active.
With computer programming all options for the Omni Mega will be displayed on the screen.
Computer programming is more straightforward than using the Remote TVIR programmer as all
features can be set at once and can be verified by up-loading the settings from the beacon.
Copies of the program settings can be saved or recalled from memory.
For Computer programming please refer to the PROG-03 Instruction Manual.
The programming described in the rest of this manual relates to the infrared TVIR programmer
only.

5.2 Default Settings
The Omni Mega is delivered from the factory with default settings including the range and flash
character required for the application. These settings are detailed in Appendix A. If there is a
need to return the light to the default settings use the Reset Factory Default option (8-1-000).

FEATURE items represent the features of the light such as flash character and intensity.
VALUES are the actual settings or value of the various features.
Appendix A of this manual provides a Table for the programming features of the Omni Mega.
Please take the time to become familiar with the table before continuing.
5.4 Visual Feedback when Using the TVIR Programmer
The Omni Mega will provide visual feedback of the programming instructions it receives from the
TVIR programmer. It is important to understand the feedback that is provided to ensure the light
will be programmed correctly.
Note:
The default operation of the Omni Mega is for the visual feedback to be provided from a green or
blue LED in the bottom lens of the beacon. If the green or blue LED is not bright enough to see
the visual feedback the main LEDs can be used for providing the visual feedback. See Section
5.5.11. When the main LEDs are used to provide the visual feedback their intensity is reduced to
4% of the maximum intensity of the Omni Mega.

Exiting Programming mode
No programming activity for 10 Seconds
The light will give two quick flashes followed by
a short pause followed by another two quick
flashes.
After this it will resume normal operation. The
light will flash its character for 16 seconds
while it checks the day/night settings. If it is
daytime and the light is set to operate at night
only the light will turn off.
5.4.1 The Omni Mega Will Not Enter Programming Mode
If you find the beacon will not enter the programming mode it will be caused by one of 2 reasons:
•The battery in the TVIR Programmer is missing, or the plastic battery insulator has not been
removed, or the battery has low voltage.
•There is no power supply connected to the light or it is out of the specified voltage range.
If the beacon enters programming mode but rejects all commands then it requires a security PIN to
be entered by the operator to allow programming. Refer clause 5.5.10.
5.4.2 Becoming Familiar with the Syntax and Flash Feedback
If you have not used the Vega TVIR Programmer before, spend some time learning how the light
will respond to the various programming actions. Make sure the Omni Mega is connected to an
appropriate power supply voltage with sufficient current capacity and experiment with the following.

rejected and an error indicated by 3 quick flashes.
The beacon will then return to programming mode and
is ready for a new instruction.
3. Exit programming mode
Leave the programmer idle for 10 seconds
The light will give two quick flashes followed by a short
pause followed by another two quick flashes.
After this it will resume normal operation. The light will
flash its character for 16 seconds while it checks the
day/night settings. If it is daytime and the light is set to
operate at night only the light will turn off.
Read System Information
To read the voltage level of the battery or supply, determine the Syntax from Appendix A:
Operation =System Checks =3
Feature =Battery Voltage =1
The programming sequence to get the information is 31
1. Enter programming mode
Press the red standby button for 5 seconds
The light will give 4 quick flashes to indicate it has
entered programming mode
2. Enter the programming sequence for the
information (31)
The light will flash once each time a key on the
programmer is operated.
When the sequence is completed and accepted the
light will provide the voltage level in a series of flashes
(e.g. 23.2VDC). Two quick flash followed by a 0.5sec
gap followed by 3 quick flashes followed by a 0.5
second gap followed by two quick flashes.
3. Exit programming mode
Leave the programmer idle for 10 seconds
The light will give two quick flashes followed by a short
pause followed by another two quick flashes.
After this it will resume normal operation. The light will
flash its character for 16 to 20 seconds while it checks
the day/night settings. If it is daytime and the light is
set to operate at night only the light will turn off.
5.4.3 Deciding what Settings are Required
Appendix D contains tables for noting the program settings of the Omni Mega.
As the Omni Mega is delivered from the factory with default settings, it is only necessary to
program the settings that need to be changed. The “Read Settings” feature can be used to note
the values already programmed.

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 18 of 56 VLB-92 V1.19
Once the required settings are known use the second table in Appendix D to note the correct
syntax and programming code from programming tables in Appendix A.
5.4.3.1 Programming or Reading Multiple Settings
Each feature can be programmed one at a time as done in the examples given, by entering and
exiting the program mode each time a feature is programmed. However this can be extremely
time-consuming to enter multiple settings as it is necessary to wait for the Omni Mega to flash its
response and return to normal operation before entering the programming mode again.
To avoid this difficulty the various settings can be programmed sequentially. Once the Omni Mega
has accepted a program sequence and has flashed back the value code, the next program
sequence can be entered. If there is a delay of more than 10 seconds after the confirmation
flashes before entering the next program sequence the Omni Mega will exit the program mode.
The use of the table in Appendix D will allow all the programming sequences to be pre-determined
and allow for a quick entry of the program settings without the need to exit the programming mode.
5.5.0 Programming Features
(Refer to Appendix A for the full list).
5.5.1 Flash Character
Vega lights are pre-programmed with 246 standard characters represented by a 3-digit code XYY.
The first digit of the code represents a flash type such as 1YY for Isophase characters. If flash
characters are required that are not included in the standard set these can be included if advised
at time of order. These would then be available for programming under Custom character type
9YY.
Operation =Program (or read) =1 (or 9)
Feature =Flash character =0
Value =Select from Appendix D =XYY
5.5.2 Custom Flash Character.
When programmed the flash character code for the custom character is 999.
To program the custom character the details of the on and off periods of the flash character has to
be recorded.
The programming a custom character has its own syntax and this needs to be followed correctly to
be able to program the character successfully.
Operation =Custom Character =2
Value =Code for the character
The code is entered in a series of 3 digit values representing an on period or off period. Each 3-
digit value is a multiple of 0.05 seconds. The 3-digit code for a 1 second on or off period would be
020 (20 multiplied by 0.05 seconds is 1 second).
The following restrictions apply:
The minimum period that can be programmed is 0.1 second or the code of 002.
The maximum period that can be programmed is 12.75 seconds or the code of 255. For
longer periods than 12.75 seconds an ADD code can be entered
There are two special codes used as part of the custom character programming
The ADD code to get on or off periods greater than 12.75 seconds = 001
The termination code when the programming of the custom character is finished = 000
Appendix C provides a work sheet, and an example, for programming a Custom Character
If an error occurs when entering a custom character the Omni Mega will flash the error code of 3
quick flashes.

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 19 of 56 VLB-92 V1.19
Programming a custom character creates a flash character with code 999. To get the Omni Mega
to use the custom character the value of 999 must be entered as the flash character.
5.5.3 Day/Night Use of the Light
The Omni Mega is capable of operation at night only or both day and night. The default setting
when the beacon is shipped is to operate at night only.
How the Omni Mega transitions from day to night mode and vice versa is determined by the
programmed day and night Lux levels. There are 9 different day/night transition light levels
allowing for a shorter or longer night.
Operation =Program (or read) = 1 (or 9)
Feature =Day/Night Control = 4
Value =Select from Appendix A =XYY
The first digit of the Day/Night Control value programs Day or Day/Night operation.
0YY allows night time operation only
1YY allows day and night operation
The YY digits of the Day/Night Control Value determine when the Day/Night transition occurs. The
Lux levels of the 9 settings are detailed in Appendix A. The accuracy of the light sensor is ±10%.
5.5.4 Intensity Settings
A different effective intensity setting can be programmed for both day and night operation. By
having different intensity settings the Omni Mega can be operated at a higher intensity during the
day than at night. The programmable effective intensity settings are provided in Appendix B.
The effective intensity is programmed into the Omni Mega. The peak intensity is controlled
automatically according to the flash character to maintain the required effective intensity. This is
done by increasing the intensity by the Schmidt Clausen multiplier for LED lights:
(Flash period in seconds+0.2)/Flash period in seconds
Operation =Program (or read) =1 (or 9)
Feature =Intensity =1 for night intensity, 2 for day intensity
Value =Select from Appendix B =XXXX
5.5.5 Synchronising Options
The synchronisation options available are as follows:
Product
Hard wired
GPS
VLB-92 Omni Mega
Yes
External GPS using Vega VSU-29
For Vega LED products the sync pulse has a positive to negative transition.
Each light can be set to be a sync master or sync slave. As a slave the Omni Mega will not
generate sync pulses. As a master a sync pulse will occur at the start of the flash character.
Where the lights connected are all masters the first light to send a sync pulse will control the other
lights.
In slave mode the Omni Mega will operate on the basis of the sync pulses received and will stop
operating after a programmed number of flash cycles after the sync pulse is lost.
Operation =Program (or read) =1 (or 9)
Feature =Synchronisation =3
Value =XYY (999 disables synchronisation)
X determines if the light is a master or slave unit.
0YY Master
1YY Slave

Instruction Manual VLB-92 Omni Mega LED Beacon © Sabik Oy, Dec 2018
VLB-92 Omni Mega LED Beacon Page 20 of 56 VLB-92 V1.19
YY allows for the start of the flash character to be delayed from 0.0 seconds to 9.9 seconds in
0.1second increments. For example YY=25 would provide a delay of 2.5 seconds.
When an external GPS sync unit is used, such as the Vega VSU-29, refer to the manual for this
device.
5.5.5.1 Loss of Sync when in Slave Sync Mode
To program a slave Omni Mega to keep running for a number of flash cycles after the loss of the
master sync pulse.
Operation =Program (or read) =1 (or 9)
Feature =Flash count on Loss of Sync =7
Value =0YY where YY is the number of
flashes (999 = never stops flashing)
5.5.6 Operation Mode
The Operation Mode provides control of how the Omni Mega will operate.
•Normal, Failsafe (001): Allows Normal
Operation and beacon stops working if an error is
detected.
•Normal, Best Effort (002): Allows normal Operation
and beacon will operate with diminished performance if
error detected.
•Beacon On Output Test (005): The Beacon On
output will be asserted for 10 seconds.
•AIS Beacon On Output Test (006): The AIS Beacon
On output will be asserted for 10 seconds.
•Beacon Fail Alarm Test (007):Beacon Fail will be
asserted for 10 seconds and Beacon OK will be
simultaneously de-asserted for 10 seconds.
•Test mode (008): Temporary 4 minute test mode.
To change the operating mode of the Omni Mega
Operation =Program (or read) =1 (or 9)
Feature =Operation Mode =5
Value =YYY where 001 is Failsafe mode.
(Refer to Appendix A for other codes)
5.5.7 Programming Mode
Programming Mode controls the operation of the IRDA port. The RS232 (or RS485) port is always
on.
The IRDA or the RS232 port can be used for Computer programming or for the external monitoring
of the Omni Mega.
To begin using a Computer for programming with the IRDA port it will need to be turned on using
the TVIR remote programmer. Information on using the IRDA port to program the Omni Mega is
provided in the Supplementary Programming manual (PROG-03). After completing programming
with PROG-03 via the IRDA port, it is recommended that the IRDA port be turned off (this is the
default state) before the Omni Mega is installed. This precaution will reduce the possibility of IR
interference with the TVIR controller input.
Monitoring the Omni Mega using the IRDA or RS232 (or RS485) port can be continuous or on
demand, when data is requested by an external device. Only one of the ports can be used for
monitoring at any time. Details of the protocol to exchange data with the beacon is provided in
Appendix G
