HASSEB ASTER LOCK
hasseb MasterClock is an easy to use battery operated master clock to drive
mini
slave clocks used for example in institutions like factories, offices, and schools.
The device sends 24 volts voltage pulses every minute, every 30 seconds, or
every second to drive the clock. The device utilizes simple Windows software to
control the settings and fine tune the crystal.
INSTALLATION
The device has a two wire connector to attach the slave clock to the device.
Depending on the settings, unipolar or bipolar pulses are sent out every minute
or every 30 seconds to drive the clock.
Many slave clocks have three wires instead of two, to drive the solenoid of the
hour, and can be joined with one or the other of the wires. In most cases hasseb
MasterClock is capable to drive also three wire slave clocks. However, it is
mini
your responsibility to check the connection of your particular device!
ADJUSTING TIME
The time can be adjusted by pressing the push button. The device will send a
single pulse every time you press the button. If you keep the button pressed, the
device sends successive pulses at the interval of two pulse length times.
CONTROL PROGRAM
By default the device will send a bipolar pulse every minute with a pulse length
of 500 ms. If the default settings are not suitable for your slave clock, an easy to
use Windows program MasterClock.exe can be used to configure the
MasterClock device. The MasterClock
mini
cable needs to be connected only when configuring the device.
The MasterClock is visible to the host computer as a human interface device,
mini
such like mouse or keyboard, and requires no drivers.
Due to the software, which is optimized for extremely low standby current
consumption, it is important to connect the USB cable between the
MasterClock device and computer before powering the device. If the USB
mini
cable is connected after the MasterClock
