VLB-67 goes immediately to Storage mode. After the beacon sees 1
minute of darkness it remains in Storage and reverts to Y=0.

Programming Mode
Programming Mode controls the operation of the IRDA and RS232/RS485 data ports. Only one of
the ports can be used at any time. When in use the background power consumption of the VLB-67
will be higher and this must be taken into account when calculating the power usage of the
beacon.
The IRDA port is used for Computer programming of the VLB-67. To begin using a Computer for
programming the IRDA port will need to be turned on using the TVIR remote programmer.
Information on the IRDA operation is provided in the Supplementary Programming manual (PROG-
01). Remember to turn the IRDA port off before the VLB-67 is installed to reduce the background
power consumption of the beacon.
Monitoring using the IRDA or RS232/RS485 port can be continuous or on demand when data is
requested by an external device. The on demand option will use less power.
Protocol for the RS232/RS485 port is provided in Appendix G
Operation
=Program (or read)
=1 (or 9)
Feature
=Operation Mode
=6
Value
=000 has both IRDA and RS232 port disabled.
See Appendix A for other settings
5.8
Battery Thresholds
The VLB-67 has programmable battery threshold settings designed to protect a battery from
damage by being over discharged. If the low threshold is reached the beacon will turn off until
the battery voltage is above the high voltage threshold. Where no batteries are used the low
voltage threshold can be disabled.
Operation
=Program (or read)
=1 (or 9)
Feature
=Operation Mode
=8 Low battery threshold (9 High battery threshold)
Value
=YYY in tenths of Volts
The value range for the Low Threshold is 000 to 119 (999 disables the Low voltage threshold).
The value range for the High Threshold is 080 to 138 (999 sets the default setting 12.8VDC).
Take care in setting the high threshold to ensure the voltage of the battery will reach this voltage
during charging. If the high threshold is set too high, the light may not resume operation after a
low voltage threshold shutdown. Disconnecting and reconnecting the battery or putting the light
into TVIR programming mode will reset the high voltage threshold restart.
5.9
System Checks
The VLB-67 beacon contains details of manufacture including calibration details, firmware version,
and LED type used. This information is useful should there either be a problem with the VLB-67 or
where it is necessary to locate the correct manual for the serial number of the beacon.
The supply voltage to the VLB-67 can also be read as a quick means of checking battery voltage.
Operation
=Read Only
=3
Feature
=Operation Mode
=1 for battery voltage, (see Appendix A for others)
Value
=Series of flashes providing the requested value.
