Downloading event from a reader
In order to read event log from a reader, it has to be connected to USB port of PC computer with
Patrol Master software launched. In Readers tab click Connect button – computer will establish
connection with the reader, showing message
ONLINE
in
Status field. When reader is online click
Download events button in Readers tab – software will download and show all events from reader.
Downloaded events are not erased from reader’s memory and can be downloaded again if
necessary. If it is required, events can be set as archival (button
Delete events from reader) and
will be omitted while downloading event log for the next time. Nevertheless archival events can be
restored and set again as actual by means of button
Recover deleted events.
Note : There is no software method to erase events from reader’s memory. Old events are kept in
the memory until they are overwritten by new ones, when 32 000 event limit is reached. After that
there is no way to restore old events as they physically do not exist in the memory anymore (their
memory cells have been replaced by new events). Because of relatively large buffer size (32k),
causing memory overflow deliberately is practically very difficult and requires large amount of time
(about 88 hours of continuously reading cycles) to do it.
Events downloaded from a reader can be browsed and analyzed on computer’s screen as well
printed on connected printer.
Patrol Master software enables writing event log to special file of
.xml extension. These files are totally independent from configuration files RGT, and can be loaded
to
Patrol Master software or browed and processed in another software.

OWER SUPPLY
Reader can be supplied from:
rechargeable LR6 (AA size) batteries
ordinary (one time use) batteries
PC’s USB port
AC charger
Factory new reader is delivered with NiMh/2100 mAh batteries fully charged and formatted.
Normally, this batteries can provide up to 8000 read cycles with LED backlight switched off or 3000
with 100% LED backlit. These numbers are continuously reduced with batteries getting older. In
general, it should be assumed, that rechargeable batteries should be replaced once a year or two
(depending on intensity of usage).
When battery is low, reader displays message
Battery weak
accompanied by 2400Hz/1800Hz
alarm signal. In order to continue work, guard should press the ON/OFF button. If not, reader will
not go further and switch off. Once warning is confirmed by pressing ON/OFF button reader will
continue work however with every read cycle it will remind the user about week battery but will not
require message confirmation. Displaying
Battery weak
message is a warning for the user that
batteries should be charged or replaced soon. For battery charging use the dedicated charger
delivered with the PATROL II LCD set or charge them directly from the PC USB port.
Note: It may happen that PC USB port is not able to provide amount of power to charge batteries
(up to 0.5 A are required for battery charging). In such situation charging should be performed
from another computer or using AC charger attached to the PATROL II LCD set.
It is recommended that only original AC charger provided with a reader should be used. Using
different types of chargers does not guarantee a proper work of the device and can damage
device’s circuits and/or batteries.
Even without any source of supply (e.g. when batteries are being removed) reader keeps its
internal clock running. This is maintained by an additional (internal) backup battery which does not
require to be replaced during reader’s planed lifetime (i.e. 10 years).
