4.5 Wiring of trigger inputs and outputs
Depending on the peripherals to be connected,
the connection work may need to be carried out
by an electrical specialist.
Example: Safety Extra Low Voltage (SELV)
exceeded

NOTICE
Danger of damage to the product and the connected
devices caused by overvoltage!
Do not engage or disengage the trigger lines while
under power
Check the trigger connections for correct wiring
The wiring of the trigger inputs and trigger
outputs depends on the customer's peripherals.
For more information, see manufacturer's
documentation.
Trigger input and output on the rear of the product
The GND pins of connections X31 and X32 are connected
to GND in the product and with the encoder connections.
A trigger is triggered upon each edge from LOW to HIGH.
Assignment of the differential signals:
U : LOW to HIGH
Trigger,In+
U : HIGH to LOW
Trigger,In–
Recommendation
The external trigger source should address the product via
differential signals. If the application requires single-ended
signals for triggering, the sensitivity to noise increases
because the EMC Directives according to which the
product has been tested are not complied with.
In this case, we recommend using 5 V TTL signals for
addressing the product and wiring the differential signals
as follows:
Do not wire the vacant input and switch off the
terminating resistor
Use U for triggering upon rising edge
Trigger,In+
Use U for triggering upon falling edge
Trigger,In–
External trigger input X31
Four independent differential inputs for the triggering of
trigger events are supported.
A 120 Ω terminating resistor can be connected.
For pin layout according to RS-485, see "M", Page 135.
External trigger output X32
Four independent differential outputs with individual
assignment to internal trigger sources of the product are
supported.
For pin layout according to RS-485, see "N", Page 135.

4.6 Connecting a computer
Network participants that are not required
by the application may cause interference.
HEIDENHAIN therefore recommends
connecting the EIB 74x through a dedicated
network connection in order to ensure
interference-free data transfer and maximum
performance.
A computer can be connected to the Ethernet port X4.
For information on the location of the connections, see
"Rear panel", Page 24.
For information on the technical requirements, see "",
Page 31. TCP/IP and UDP protocols are required for
communication.
The connection between the product and the
PC may be connected or disconnected even
while the product is switched on.
For X4 pin layout, see "O", Page 136.
Commissioning on the computer
For commissioning, the device must first be connected to
the computer through a point-to-point network connection.
Set the following TCP/IP configuration on the computer
for the network card being used:
Fixed IP address (not to be procured automatically)
IP address: 192.168.1.1
Subnet mask: 255.255.255.0
Connect the Ethernet port of the computer to
connection X4 using an Ethernet cable
Switch on the product
The STATUS LED shines green
The device is ready for operation
You should check by means of a ping test (in
the Windows prompt or Linux shell) whether
the device can be addressed via the network.
For this purpose, use the following syntax:
ping 192.168.1.2
