DS4800 REFERENCE MANUAL 6 6 TYPICAL LAYOUTS The following typical layouts refer to system hardware configurations. Dotted lines in the figures refer to optional hardware configurations within the particular layout. These layouts also require the correct setup of the software configuration parameters. Complete software configuration procedures can be found in the Guide To Rapid Configuration in the Genius™ Help On Line. 6.
TYPICAL LAYOUTS 6 In this layout a single scanner functions as a Slave node on a Fieldbus network. The data is transmitted to the Host through an accessory Fieldbus interface board installed inside the CBX500 connection box. Scanner configuration can be accomplished through the Auxiliary interface using the Genius™ configuration program or Genius™ based Host Mode programming.
DS4800 REFERENCE MANUAL 6 6.2 PASS-THROUGH Pass-through mode allows two or more devices to be connected to a single external serial interface. Each DS4800 transmits the messages received by the Auxiliary interface onto the Main interface. All messages will be passed through this chain to the host. When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
TYPICAL LAYOUTS 6 An alternative Pass-Through layout allows the more efficient ID-NET™ network to be used. This layout is really an ID-NET Master/Slave Multidata layout which also allows each scanner (Master and Slaves) to accept input on the Auxiliary interface, for example to connect a device such as a hand-held reader for manual code reading capability. Each DS4800 transmits its own messages plus any messages received by its Auxiliary interface onto the ID-NET™ interface.
DS4800 REFERENCE MANUAL 6 6.3 ID-NET™ The ID-NET™ connection is used to collect data from several scanners to build a multi-point or a multi-sided reading system; there can be one master and up to 31 slaves connected together. The slave scanners are connected together using the ID-NET™ interface. Every slave scanner must have an ID-NET™ address in the range 1-31. The master scanner is also connected to the Host on the RS232/RS485 main serial interface.
TYPICAL LAYOUTS 6 For a Master/Slave Multidata layout each scanner has its own reading phase independent from the others; each single message is sent from the master scanner to the Host computer.

TYPICAL LAYOUTS 6 The Master scanner can communicate to the Host as a Slave node on an Ethernet TCP/IP network. This example requires using the accessory BM2x0 Ethernet interface board installed inside the CBX500 connection box. System configuration can be accomplished through the Auxiliary interface of the Master scanner (internal CBX500 9-pin connector) using the Genius™ configuration program or Genius™ based Host Mode programming.
DS4800 REFERENCE MANUAL 6 Alternatively, the Master scanner can communicate to the Host as a Slave node on a Fieldbus network. This requires using an accessory Fieldbus interface board installed inside the CBX500 connection box. System configuration can be accomplished through the Auxiliary interface of the Master scanner (internal CBX500 9-pin connector) using the Genius™ configuration program or Genius™ based Host Mode programming.
TYPICAL LAYOUTS 6 6.4 RS232 MASTER/SLAVE This interface is provided for backward compatibility. We recommend using the more efficient ID-NET™ network for Master/Slave or Multiplexer layouts. NOTE The RS232 master/slave connection is used to collect data from several scanners to build either a multi-point or a multi-sided reading system; there can be one master and up to 9 slaves connected together. The Slave scanners use RS232 only on the main and auxiliary serial interfaces.
DS4800 REFERENCE MANUAL 6 6.5 MULTIPLEXER LAYOUT This interface is provided for backward compatibility. We recommend using the more efficient ID-NET™ network for Master/Slave or Multiplexer layouts. NOTE Each scanner is connected to a Multiplexer (for example MX4000) with the RS485 halfduplex main interface through a CBX connection box.

Dust, dirt, etc. on the window may alter the reading performance. Repeat the operation frequently in particularly dirty environments. Use soft material and alcohol to clean the window and avoid any abrasive substances. Clean the window of the DS4800 when the scanner is turned off or, at least, when the laser beam is deactivated.
TROUBLESHOOTING 9 9 TROUBLESHOOTING 9.1 GENERAL GUIDELINES When wiring the device, pay careful attention to the signal name (acronym) on the CBX100/500 spring clamp connectors (chp. 4). If you are connecting directly to the scanner 25-pin connector pay attention to the pin number of the signals (chp 5). If you need information about a certain reader parameter you can refer to the Genius™ program help files.
DS4800 REFERENCE MANUAL 9 TROUBLESHOOTING GUIDE Problem Power On: the “Power On”/”Ready” LED is not lit Suggestions Is power connected? If using a power adapter (like PG 6000), is it connected to a wall outlet? If using rail power, does rail have power? If using CBX100, does it have power (check switch and LED)? Measure voltage either at pin 13 and pin 25 (for 25-pin connector) or at spring clamp Vdc and GND (for CBX).
TROUBLESHOOTING 9 TROUBLESHOOTING GUIDE Problem Reading: Not possible to read the target barcode (always returns No Read) or the Auto Setup procedure Fails. Suggestions Check synchronization of reading pulse with object to read: Is the scan line correctly positioned? Place barcode in the center of scan line and run Test mode (selectable by Genius™ as an Operating Mode).
