Synchronization Interface
To allow the synchronization of up to 32 readers, the Series 2000 firmware provides six types of
synchronization (or No Sync if you are not going to use synchronization)
• Wireless synchronization
• Wireless
• Wired
• Combined wireless/wired
• Master/slave (with or without acknowledgement)
• Triggered
This specification covers the way the readers have to be connected for the wired, combined
wireless/wired, Master/Slave and triggered synchronization.
When you have completed the hardware synchronization, you must run the configuration utility
(S2_Util.exe) as described in Section 2.4, in order to tell the system which synchronization method you
have installed, and then set the dipswitch S1.1 to the ON position.
2.8.2 Wired and Combined Wireless/Wired Synchronization
Figure 2-15 shows the way in which the Control Module must be connected for a wired and combined
wireless and wired synchronization. The Control Module also has to be software configured to the chosen
synchronization method. Table 2-13 explains the setting of jumpers 12, 13 and 14 (JP12, JP13 and JP14).

2.8.3 Master/ Slave Synchronization without Acknowledgement; Triggered
Synchronization without Acknowledgement
Figure 2-16 shows the way that the Series 2000 readers have to be connected for Master/ Slave
synchronization or Triggered synchronization, both without acknowledgement. The individual SW
configuration (Master or Slave) is shown in Table 2-14 and Table 2-15. The tables also explain the setting
of jumpers 12, 13 and 14 (JP12, JP13 and JP14).
