8. 5 Connecting the interfaces
All of the interfaces are routed via the 15-pin D Sub HD connector
À
(
Table 3
).
8. 5. 1 Connecting the host interface
The CLV is equipped with two host interfaces (RS 232 and RS 422/485). One of
these must be selected for data communication with the host/PC. If the RS 232
interface is not connected to the host, it can be used exclusively to monitor data
traffic on the parallel RS 422/482 interface.
TIP:
The internal modules of the CLV may be damaged irreparably if the data interface
is connected incorreclty.
Ø
Connect the host interface of the CLV to the host in accordance with the EMC
requirements using shielded cables(
Fig. 4
)
Ø
To prevent interference, do not lay the data cables over a long distance parallel
to the power supply and motor cables, e.g. in cable ducts
Ø
Apply the shield on one side (SICK recommendation)
