Mounting & Cabling
o
Use the fixing elements of the connectors.
o
Avoid mechanical stress regarding the cables and
connectors.
If you are using drag chains, make sure to use appropriate
cables.
Cover all unused connectors with a protection cap.
During cabling, the Irinos-System and all other devices must be
turned off.
The following shows a typical connection sequence:
a) Connect Ethernet cable .
b) Connect ILink cables .
c) Connect measurement equipment and digital in- and outputs.

Ethernet cabling
The Ethernet interface is of standard type (no special
enhancements), like it is used for example in IT networking. This
allows connecting the Irinos-System to any standard PC or laptop
Ethernet port. It can also be used with standard Ethernet switches.
The communication between the Irinos-System and the PC has
been designed for fault tolerance. In case a data packet is lost, it will
be retransferred automatically. This retransmission results in a delay
of the availability of measurement values. Hence it should be an
exceptional case. (It has no influence on the realtime capability of
the system, since the values are internally buffered.)
In order to minimize the number of retransmissions, it is strongly
advised to use a direct connection between the Irinos-
System and the PC
. Therefore the Ethernet interface of the Irinos-
System is directly connected to an unused Ethernet interface of the
PC. Experience has shown, that retransmissions almost never occur.
The Irinos-System has not been designed for use with routers, VPN
connections, wireless connections and similar.
An integrated "cross-over detection" ensures that it does not
matter, whether 1:1 or crossed Ethernet cables are used.
By factory defaults, the DHCP-Server of the Irinos-System
is activated. This is a good choice for a direct connection to
