6. Information
The GPS Docking has « banana » output connector to provide a signal TOP-MINUTE which is useful
to synchronize other timing systems.
If the GPS is used only for the CP 540, it is recommended to wait 4 – 5 mins before to switching it
OFF (« memorize » the GPS precision)
The GPS Docking has an Input / output « Master / Slave ». This mode of synchronization between
several CP 540's is very useful for the timekeeper, to guarantee absolute precision between different
systems.
For example: System A (Master) and the back-up system B (Slave).
Connect the CP 540 A « Master » to CP 540 B « Slave » with the special cable HL540-11.
The CP 540 A is synchronized with the Time of Day, manually or with GPS.
The CP 540 B is automatically synchronized by the CP 540 A by choosing Master/Slave in the
Synchro Menu.
If the Main system A is disconnected or communication fails, the back-up system B will operate with its
own time of base.
The Drift (DEV) described later « Synchronization by GPS » is also into the mode. Thus, if the Main
System A is again operational, it will take its main function as Master if the Drift is lower that 100 µsec.
All information is of course printed.
7. How to charge the Docking accumulator
The Docking could be charged alone or connected to a CP 540.
Charge the docking with the power supply HL 540-1 from the CP 540
Connect the power supply to the POWER connector of the Docking (connector 3 poles).
The LED located at the bottom of the Docking allows you to see the charging status.
LED is red during the charge (6 hours for a complete charging)
o
LED is green when the docking is fully charged
o
When the CP 540 is used with the Docking, the external power supply should be connected to the CP
540.
WARNING
The Docking should be not charged with a temperature lower that 0°C / 32°F.
Remark:
The charging status of the Docking is displayed on the CP540 LCD if charged together.
If the Docking is too discharged, the batteries of the CP 540 will power the system. If the power is too
low, the Time on the LCD will flicked and the printer will print « Low battery » before to switching OFF
automatically.
When the charge indicator of the Docking shows 50% on the LCD (Docking Menu), you still have at least
4 hours of autonomy.
