4.2.5
Selecting the mounting location
When you select the mounting location, the distance between the CLV490 and the host and
between the CLV490 and the bar code are extremely important.
Distance between the CLV490 and the host
The CLV490 can be mounted at a maximum distance of 1,200 m (3, 937 ft) from the host
without a connection to the SICK network or a bus. In practice, however, the distance de-
pends on the physical configuration of the host interface and the data transfer rate (see
).
Distance between the CLV490 and the CDB420 or CDM490 Connection Module
The CDB420 or CDM490 Connection Module should not be located further than 10 m
(32.8 ft) from the CLV490, since the "CLV-Setup" program on the PC accesses the auxiliary
interface (RS 232) of the CLV490 via this module.
4.2.6
Mounting accessories
The CLV490 is secured in position using the two tapped blind holes (M6) above the electrial
shows the location of the threads near the line scanner.
The dimensions of the CLV490 housing are shown in
