- The pin
external synchronization source, such as a function generator
- The termination resistor R

4.3.12.2 Internal Synchronization

One IFC2411 controller (master) synchronizes one or more controllers (slaves).
Synchronization
Fig. 26 Connections and signal level internal synchronization
Activate the termination resistor (120 Ohm) in the last controller (slave n) in the chain.
Star synchronization
Sync+
Connect pins
(master) in a star shape to pins
from controller 2 (slave) to controller n, in order to
synchronize two or more controller to one another,
see Fig. 27
- Sub-loop length less than 30 m in star synchronization
Use shielded cables with twisted wires.
Connect the cable shield to pin 3 of the 5-pin terminal block.

If the sensors are operated by way of the EtherCAT interface, then synchronization can also be achieved without the
synchronization line.
