Connections
The NETLink PRO ETH has the following connections:
•
RJ45 socket for connecting the unit to a commercial type switch or
hub using a standard CAT5 TCP cable (straight).
If the NETLink PRO ETH is to be operated directly on a PC, mostly
a cross adapter (for accessories, see Section 3.5)or a CAT5 TCP
cable (cross) must be used.
•
Power supply socket for 24 V DC power supply.
This power supply option can be used, if the programmable controller
used does not provide any or only insufficient power on the bus
connector.
•
Bus connector with programming unit socket, switchable terminating
resistor, and 1.2 m connecting cable.
The programming unit socket of the bus connector allows further bus
nodes to be plugged in.
The terminating resistor must be connected (ON) if the NETLink
PRO ETH is at the beginning or end of a bus segment. If this is not
the case, the switch position must be OFF.
The 1.2 m connecting cable is an ‘active cable’. This means there is
no spur line, which avoids interferences with high baud rates.
