Physical InterfaceBasler scout 535.4 Cabling Requirements5.4.1 IEEE 1394b CableThe maximum length of the IEEE 1394b cable used between the camera and the adapter in yourPC or between the camera and a 1394b hub is 4.5 meters as specified in the IEEE 1394 standard.Standard, 9-pin, shielded 1394b to 1394b cables should be used.5.4.2 Standard I/O CableThe end of the standard I/O cable that connects to the camera must be terminated with a Hirosemicro plug (part number HR10A-10P-12S) or the equivalent. The cable must be wired as shown inFigure 34.The maximum length of the standard I/O cable is at least 10 meters. The cable must be shieldedand must be constructed with twisted pair wire. Use of twisted pair wire is essential to ensure thatinput signals are correctly received.Close proximity to strong magnetic fields should be avoided.The required 12-pin Hirose plug is available from Basler. Basler also offers a standard I/O cableassembly that is terminated with a 12-pin Hirose plug on one end and unterminated on the other.Contact your Basler sales representative to order connectors or standard I/O cables.The camera is backward compatible with IEEE 1394a devices. If you will beconnecting the camera to an IEEE 1394a device, you must use a conversioncable. The cable should have a 9-pin IEEE 1394b plug on the end that connectsto the camera and a 6-pin IEEE 1394a plug on the end that connects to the device.The standard I/O cable is intended for use if the camera is not connected to a PLCdevice. If the camera is connected to a PLC device, we recommend using a PLCI/O cable rather than the standard I/O cable.You can use a PLC I/O cable when the camera is not connected to a PLC device,if power for the I/O input is supplied with 24 VDC.See the following section for more information on PLC I/O cable.
