Data transfer via SATEL Compact-4BT
Data can be sent via Bluetooth, USB or RS-232 which are ON simultaneously so no extra setting
is needed to choose which port shall be opened, choosing the data port is done by selecting the
dedicated cable.
If Bluetooth port is used for data transmission USB and RS-232 ports are also operational. User
should not send data to two different ports simultaneously as this might corrupt the data.
All serial ports including Bluetooth do not output or pass through data to other serial ports, all
data input is directed to internal UHF modem.

Compact-4BT.

external source up till 2 Amps @ 12V. When external DC supply is connected all power is
drained from that source. After battery is fully charged the external DC supply will continue to
feed the device hence not draining the battery. DC supply can be disconnected at any time or it
can be left connected all times.
When external DC supply is connected Battery LED will illuminate Green or blinking Green when
charging is ongoing.
If during the charging Red LED starts blinking there is an internal error in charging process. Error
can occur in a following circumstances; charging temperature is too low or high, maximum
charging time has exceeded, battery absent or defect. In a case of error occurrence assure that
the device is in a proper temperature range. Notice that inner temperature may be different than
outside, or the device may take a while to cool down or heat up. If charging takes too long or
behaves not normal, battery may be defect. In this case contact manufacturer for further
instructions.
