Operating Instructions Chapter 5

CLV490 Bar Code Scanner

Electrical installation

For connecting the host interface via the CDB420 or CDM490 Connection Module, see the

Operating Instructions for the "CDB420 Connection Module" (no. 8010001, German/En-

glish) respectively the Operating Instructions for the "CDM490 Connection Module"

(no. 8010005, German/English).

Terminating the RS 422 interface:

The interface can be terminated in the Connection Module. See the Operating Instructions

for the "CDB420 or CDM490 Connection Modules".

Activating the RS 232 interface:

The RS 232 interface can be activated with the "CLV-Setup" program:

1. Choose the H

OST INTERFACE tab.

2. Choose the RS 232 option from the H

ARDWARE drop-down list under DATA FORMAT.

3. Download the data to the CLV490 by clicking in the toolbar.

The D

OWNLOAD PARAMETERS dialog box is displayed.

4. Confirm the dialog box by choosing P

ERMANENT.

The CLV490 uses the RS 232 version of the host interface.

Tip The communication parameters can be changed, if necessary, on the H

OST INTERFACE tab.

To do so, change the values under D

ATA FORMAT and INTERFACE PROTOCOL.

5.5.5 Connecting the CAN interface

Connecting the CAN Interface 1 and configuring the CLV490 to use the device in the SICK-

specific CAN Scanner Network or in a CANopen network see the Operating Instructions

“Application of the CAN interface“ (no. 8009180, English edition).

5.5.6 Connecting the PC

The CLV490 is operated and configured with the PC-based "CLV-Setup" program. In order

to do so, you must connect the device to the PC via the auxiliary interface (auxiliary inter-

face). Unlike the host interface, the auxiliary interface has a permanent data format and a

fixed data transfer rate. Fig. 5-4 shows how the auxiliary interface is connected. The cable

length should not be more than 10 m (32.8 ft).

1. Switch off the PC and power supply to the CDB420 or CDM490 Connection Module.

2. Connect the PC to the internal, 9-pin "Aux" plug on the Connection Module.

To do so, use a 3-core RS 232 data cable (null modem cable), e. g. no. 2014054

(RxD and TxD crossed).

Without the SICK Connection Module:

Connect the PC as shown in Fig. 5-4.
