8.4. Input/output synchronization

Connector P4 is used for input and output synchronization and for serial RS485 communication.

There are four independent, galvanically isolated, synchronization inputs. These inputs can be
connected directly to the system for voltages up to 24V. An external series resistor is not necessary.
Synchronization inputs may be left unconnected when not used. The state of each synchronization
input is shown by a green LED indicator next to the connector.

There are four independent, galvanically isolated, synchronization outputs. These outputs can be
used, for example, to trigger a camera or a slave controller. These outputs can be connected directly
to the system for voltages up to 60V. The state of each synchronization output is shown by a yellow
LED indicator next to the connector.

Connector P4 also provides three signals for an isolated serial RS485 interface and two signals for
an optional and non-electrically isolated external temperature sensor. The activity of the serial RS485
interface is shown by a dedicated yellow LED next to connector P4.

See the following section for more information about connector P4.

8.4.1. Synchronization inputs

The four synchronization inputs are available on the TR1+, TR1-, TR2+, TR2-, TR3+, TR3-, TR4+
and TR4- terminals of connector P4. These signals are listed in

Table 5: pinout of connector P4 for

synchronization inputs

. Be careful not to cross-connect the four synchronization inputs.
