Communication Cable

For lengths up to 15 metres, it is recommended to use pre-fabricated Ethernet twisted
pair cable FTP type, CAT5/6.
For longer cable lengths, it is recommended to use S-FTP (screened shielded twisted
pair) Ethernet cable CAT5/6.
Note that a CAT5/6 twisted pair (TP) Ethernet cable has maximum working distance of
100 m. If longer cable lengths are needed, fibre optic cables may be used along with
needed converters such as converters for fibre optic to CAT5 Ethernet and vice versa.

Data Communication

IMx-T unit communications are compliant with the Ethernet standard 10/100 Mbit
(half- and full-duplex).
IMx-T has two Ethernet ports which work like an internal network switch.

Ethernet Cable

The Ethernet TP cable on the IMx-T is connected at one of the standard Ethernet RJ45
connectors, labeled J1 and J2.
Both Ethernet ports have auto detection of crossover or straight through Ethernet cable
connection. Basically, IMx-T has a built-in Ethernet switch.
It is possible to connect IMx-T in a daisy chain up to 8 units in a single cable layout.
There are two LEDs on a RJ45 connector.

Yellow LED is the Ethernet traffic indicator which flickers whenever there is
traffic on the network.
Green LED is the Ethernet link indicator which lights up when the system is
correctly connected to another network device.
