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 Mode
=5
Value
=YYY where 001 is Failsafe mode.

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
