2.3 Sleep Mode
Momentarily pressing the OK/Power button when the Reader is displaying the main
screen will put the Reader into low power “Sleep” mode. In this mode, the screen is
switched off, tag reading stops, and any PC connection (USB or Bluetooth) is lost.
Sleep mode is useful for extending battery runtime when there is a long period
between reading tags.
The Reader can be “woken up” by pressing the OK or READ buttons. The Reader
can also be configured to auto-sleep after a certain amount of time if it is not being
used. Please refer to Section 3 for more information about configuring this setting.
2.4 Using Alternate DC Power Sources
It is possible to use alternate DC sources to charge and power the Reader
provided the following points are considered:
The charging input to the Reader operates over 11-30V DC. Connecting
voltages sources above 30V DC may damage the Reader.
Observe the polarity of the DC connection. The tip of the charger connection
is positive and the ring is negative.
The Reader requires a power source capable of providing at least 20W to
operate at full transmit power and charge the internal battery.
Use of AC adapters (particularly ungrounded types) other than the one
provided with the Reader may result in poor read range of tags due to noise.
DC Power Input Cable is an available accessory item from Biomark.
NOTE: It is possible to configure the cut-off voltage for the DC input via the settings
menu. This feature is useful when powering the reader from an external battery or
other alternate power supply. Refer to Section 3 for more information on
configuring these settings.
2.5 Connecting the Accessories
The unit should be connected to the loop antenna with the supplied cable.
Depending on what other functionality is required, the unit can also be connected
to a USB port on a PC, or USB Flash Drive.
The threaded locking collets should be fully screwed onto their mating connectors.
NOTE: When data is transferring from the reader to a USB drive, the USB icon will
show a lock symbol. DO NOT remove the USB drive while the lock status symbol
is showing. Failure to observe this procedure can result in loss or corruption of data
from the USB drive.
