MOVEMENTS AND SYNCHRONISATION
• Quartz 1.5V
The clock is completely autonomous, the time information is provided by its own time system.
• 1.5V serial impulse (for BT Chrono)
Slave clocks are connected to a radio synchronisation box (BT Chrono) that generates electrical impulses every minute.
• 24V minute impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every minute by the master clock.
• 24V second impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every second by the master clock.
• 1/2 minute serial impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every ½ minute by the
master clock.
• AFNOR TBT
The coded time distribution consists in transmitting a complete time message every second: the time on the receivers is
automatically and immediately set after connection to the clock line.
The AFNOR coded time does not interfere with other transmission, and is insensitive to other electrical interference.
Consumption TBT: 10 mA (6 VDC), 8 mA (24 VDC).
• Network Time Protocol (NTP / ETH)
Slave clocks are connected to the Ethernet network and powered by PoE (Power over Ethernet).
The time is synchronised by the time server or the master clock over the Ethernet network in unicast, multicast or DHCP
mode.
