Connectors Cn1 And Cn2 - Renishaw NCi-4 Installations- Und Benutzerhandbuch

1-4
10-way connector (CN1)
Connector CN1 is used to connect the non-
contact unit to the NCi-4 interface. The interface
automatically detects which NC unit has been
connected.
15-way connector (CN2)
Connector CN2 is used to connect the NCi-4
interface to the CNC machine tool.
Terminals 1 – 2
Used to monitor the signal from the NC3 or NC4.
Terminals 3 – 6
These are SSR outputs that can be used to
control external devices. Devices may include a
LED or a buzzer.
An output can also be used with an NC1
separate system and NC4 systems to switch the
transmitter unit on/off independently of the
receiver. Alternatively, it can act as a skip-
