4.5.6 Transmitter Carrier Phase Synchronisation (CPS)
To allow you to overcome the beat effect, the pulse width modulated oscillator signal
is accessible at the CPS connector D. All readers to be driven by one oscillator must
have their CPS connectors connected together as shown in Figure 13.
DIP switch Synchronization-SW4 determines whether the internal oscillator or the
external oscillator signal is used. When the DIP switch Synchronization-SW4 is OFF,
the internal oscillator is used and the reader is referred to as an oscillator MASTER.
When the DIP Switch Synchronization-SW4 is ON, the external oscillator signal is
used and the reader is referred to as an oscillator SLAVE.

Master Slave
If you are using carrier phase synchronization you must configure your system to
Master/Slave in order to have one common master.
Note:
Only one oscillator MASTER is allowed per synchronized system.
